The toe part of the boot has a rubber pad that provides additional protection from mechanical impacts when walking. Multi-directional tread ensures optimal grip. surface Stainless steel fittings The red, disheveled sun, yawning, creeps out from behind the distant ridges, looks at itself in every puddle, rings with drops and draws us into a festival of light and air. I would like to forget about the backpack that weighs down my shoulders, take a deep breath and look around, not at my feet. The road is far from simple... it lulls your vigilance, unfolding like a fluffy carpet, and suddenly, capriciously bending, throwing up obstacles and traps. It’s good that trekking boots have already been invented! THB "Berg" boots fix the foot, protect the feet from stones and impacts, “keep” on the terrain, do not get wet and remove excess moisture from the inside. Stability on difficult terrain, the necessary rigidity and elasticity of the boot are provided by a two-component sole (heat-resistant rubber + EVA). EVA (ethylene vinyl acetate) is a lightweight and elastic material, similar to foam rubber, with excellent shock-absorbing properties. It has low heat transfer, does not absorb moisture, and remains flexible at low temperatures. Thanks to the foamed structure of the EVA sole, the shoes spring well, easily restore their shape when deformed, retain heat, and do not allow cold to pass through. The outsole is made of wear-resistant rubber with a deep multi-directional tread that provides reliable traction on a variety of soils in any weather. The upper material combines full-grain leather with PU coating and durable, lightweight synthetic material Cordura ®, which reduces the weight of the boots and improves their breathability and wear resistance. The lining is a practical synthetic quick-drying material on a Dintex® membrane. It breathes, removes excess moisture well from the foot and maintains a comfortable temperature in the boot, protecting the feet from hypothermia. The replaceable, molded, anatomical sockliner is highly wear-resistant and antibacterial to provide arch support and ventilation. The heel supports the ankle, durable nylon lacing secures the foot tightly, and a rubber pad in the toe of the boot protects the toes from impact and increases the grip area on rocky terrain. Light, comfortable boots will make your journey shorter, just be careful and take your time while trying them on.

Unlike expensive membrane fabrics and down insulation, these materials do not require special care and do not raise the price of a jacket to sky-high heights. The hood, characteristic of Alaska, with fur trim, in combination with a high collar, covers almost the entire face if necessary, and is adjustable in terms of volume and oval of the face. The trim, made of natural or faux fur (your choice), can be detached from the hood. The inside of the collar and the edge of the hood that touches the face are lined with soft fleece. Serious barriers to wind and cold are also the windproof outer and inner flaps of the front two-way zipper, the belt and the bottom of the jacket that are tightened with a cord. Sleeves with internal knitted cuffs are adjustable with Velcro patches. The length of the jacket (up to mid-thigh) allows you to stay in the cold for a long time, and the loose silhouette does not restrict movement. Large buttons allow you to unbutton the jacket without taking off your gloves. The voluminous, warm front pockets are lined inside with a soft knitted fabric, and large buttons on the top pockets allow you to unfasten them with gloves. In addition to the six front pockets, there are two more pockets on the sleeve and two inside. A warm, comfortable jacket designed for long stays in the cold. We strongly recommend using front-loading washing machines; if you own a top-loading machine, we recommend washing clothes and equipment in a special mesh laundry bag to protect against possible damage from the washing machine drum parts. Before washing, you must fasten all zippers and Velcro fasteners and completely loosen all adjustments. If the outer fabric is membrane, then it is better to wash the product with the lining facing out (turned inside out). Wash on delicate cycle at 30°C with a double rinse cycle (it is better to use two rinse cycles to ensure that all detergent residues are removed from the fabric and insulation) and a medium spin. It is acceptable to use a drying drum at medium temperature (40-60°C) for 30-40 minutes or until completely dry; if the top fabric is membrane, it is better to dry the product with the lining out (turned inside out). You can hang dry the product with the lining facing out. To remove stubborn stains, you can treat the stains with a special solution such as Grangers Performance Wash or Nikwax Tech Wash before washing, allowing the detergent to soak in for 10-15 minutes. It is better to store clothes and equipment with synthetic insulation in a straightened (not compressed) state. How to restore DWR treatment on insulated clothing or equipment DWR is a special polymer applied to the surface of the fabric to give it water-repellent properties. DWR treatment does not last forever. During use of the product, as well as after a certain number of washes, the effectiveness of DWR decreases. If water droplets no longer roll off the surface of the fabric and wet the fabric even after washing, it’s time to restore the splashproof treatment. We recommend using a special spray-on or wash-in fabric spatter-reinforcement product such as Grangers Clothing Repel or Performance Repel, or Nikwax TX. Direct Wash-In or Spray-On. First, wash the item in accordance with the washing recommendations, then use the selected solution to restore the splash-proof treatment by spraying it directly onto the front of the item while it is still damp, or running a second wash cycle after pouring the required amount of wash-in into the washing machine . The manufacturer's instructions for the splashproof restoration product on the packaging must be followed exactly. Many DWR restoration products require heat activation, so it is best to tumble dry treated clothing and equipment on medium heat (40-60°C) for 40-50 minutes or until completely dry.

« Membrane- this is either the thinnest film that is laminated (welded or glued using a special technology) to the upper fabric, or a special impregnation that is rigidly applied to the fabric using a hot method during production. On the inside, the film or impregnation can be protected by another layer of fabric.”

From this we can conclude about an important property of membrane clothing - it is very light.

Poreless membranes they work on the principle of osmosis (not space, but osmosis - remember physics and chemistry lessons at school).

The system is as follows: vapors fall on the inside of the membrane, settle on it and, through active diffusion, quickly move to the outside of the membrane. (Again, only if there is a driving force - a difference in the partial pressures of water vapor).

What are the advantages of non-porous membranes? They are extremely durable, do not require careful maintenance, and work properly in a wide temperature range. Such membranes are usually used in top-end (expensive and most functional) products.

What are the disadvantages? At first it may seem that the products are getting wet, but this is precisely the same fumes that accumulate on the inside of the product. That is, they begin to breathe more slowly, but advanced non-porous membranes, “heating up”, sometimes surpass porous membranes in their breathing properties.

Pore membranes- these are, roughly speaking, membranes that work according to the following principle: drops of water that fall on the membrane tissue from the outside cannot pass through the pores of the membrane inside, since these pores are too small. The steam molecules that form when you sweat are freely removed from the inside of the membrane tissue through the pores of the membrane (since a steam molecule is thousands of times smaller than a drop of water, it can freely penetrate through the pores of the membrane). As a result, we obtain waterproof membrane fabric on the outside of the product and breathable (steam-removing) properties from the inside of the product. At the same time, a drop of water will not be able to seep into such a hole. But how (you ask) will clothes with holes withstand the wind? After all, wind molecules are also significantly smaller than a drop of water! In this case, the membrane works differently. The wind, entering long and narrow pores, begins to swirl and does not pass through.

What is the advantage of pore membranes? They "quickly" begin to breathe, i.e., remove evaporation as soon as you begin to sweat (provided that there is a difference in the partial pressures of water vapor inside and outside the jacket. That is, when there is a driving force).

What are the disadvantages? This membrane “dies” quite quickly, that is, it loses its properties. The pores of the membrane become clogged, which greatly reduces the breathability. If washed incorrectly, the jacket may begin to leak. This drawback can manifest itself especially strongly if you are not a particular fan of caring for your things (using special DWR sprays, detergents for membrane fabrics, etc.).

Membrane combination- everything is very cool. The system is as follows: the upper fabric is covered on the inside with a pore membrane, and on top of the pore membrane there is also a thin coating (i.e., a non-porous polyurethane membrane film). This magical fabric has all the advantages of pore and non-pore membranes without the disadvantages. But high technology comes at a high price. Very few companies use this membrane in their products...

How does a membrane “work”?

If you become the owner of membrane clothing, then you should not put it on a cotton T-shirt and go for a run in twenty-degree frost. This is how the membrane does not “work”. The idea is to keep the heat inside by wicking moisture out and preventing it from being absorbed into your clothes.
The classic scheme of protection against moisture and cold consists of three layer elements, and the membrane is only one of them, the very last.

First layer of clothing- this is thermal underwear (special thin clothing that retains the heat generated by the body). Cotton should be avoided, as it greedily absorbs moisture, and, therefore, there can be no talk of any warmth.

Second layer- woolen clothing (with an admixture of synthetic fabrics that wick away moisture) or clothing made from artificial materials such as fleece (Fleece) or Polartec. It is important that the second layer is voluminous and retains heat.

But only third, outer layer- thin membrane jacket.
If the frost is mild, then you can get by with only the first and third layers, which will provide you with mobility and mobility.

And finally, it is important to understand how moisture will be removed outside. Due to the difference between the air pressure under the membrane jacket and outside. Therefore, if you decide to sit motionless in a snowdrift, hoping for a “magic” membrane, there is a real chance of catching a serious cold. However, this does not mean at all that you need to run around like crazy waiting for a pressure difference for the membrane to “work.” It’s enough just to move more or less actively (just in case: walking is also movement).

Characteristics of membrane fabric

A membrane can be characterized not only by its structure and operating principle (with or without pores), but also by its two main parameters: water resistance and the ability to release steam.

Water resistance(or water resistance), waterproofness (millimeters of water column, mm water column, mm H2O) - the height of the water column that the membrane (fabric) can withstand without getting wet. In fact, this parameter indicates the water pressure that can be maintained without getting wet. The higher the water resistance of the membrane, the more intense precipitation it can withstand without letting water pass through it.

Vapor permeability(g/m2, g/m2) - the amount of water vapor that a square meter of membrane (fabric) can pass through. Other terms are also used: Moisture Vapor Transfer Rate (MVTR), moisture permeability. Most often, the value g/(m2.24h) averaged over a long period of time is indicated - the amount of water vapor that a square meter of membrane (fabric) can pass through in 24 hours. The higher it is, the more comfortable the clothing.

The base level is usually 3,000mm/3000g/m2/24 hours.
Mid-range membranes typically have a rating of 8,000mm/5,000g/m2/24hrs or so.
The water resistance of high-end fabrics is usually at least 20,000 mm water column, and the breathability is at least 8,000 g/m?/24 hours.

About gluing seams

Taped seams prevent moisture from penetrating through the seams, and, as a result, you feel dry and comfortable.
Inscription " all seams are sealed " means that all seams in this product are taped.

If the label says “critical seam sealing,” this means that only the main seams are taped in the product, which may or may not result in leaks in some places. It is worth noting that in products positioned by the brand as semi-urban, this option is very acceptable (usually these are products with insulation). Here, every buyer is free to choose what he wants and what is suitable for him personally.

Water-repellent coating - DWR

Look - the droplets on the fabric are not absorbed, but lie on the fabric, rolling into balls! This is a DWR (Durable Water Repellence) coating that does not allow water to pass even through the top layer of the fabric (that is, to be absorbed into it). On DWR coated fabric, water beads up and rolls easily. DWR, by the way, is not durable, and disappears over time (is washed off), and wet spots appear on the fabric (upon contact with water). This does not mean that the product gets wet, since the membrane will still not allow water to pass through, but some discomfort may be present. The resulting layer of water on top will not allow the membrane to work, no matter how cool it is. In addition, in pore membranes, in this case, water can pass through the membrane. Specially developed products with this same DWR coating (NIKWAX, WOLY, salamander), sold in stores selling extreme clothing, will help you avoid dying of DWR.

Pros and cons of membrane clothing

Pros:

it is light and comfortable: the child can move outside and enjoy a walk, rather than sitting in a stroller and only being able to move his head.
you don’t waste a lot of nerves pulling on and fastening another layer of “warmer” clothing
the child will not cry while you get dressed and go outside.
protects well from rain and snow, durable and lightweight;
again, your nerves are calm and you don’t have to run home after another fall in a puddle.
it is not blown by the wind and removes body fumes well;
it is suitable for both not very cold windy weather and frosty weather;
You need to wear less clothing underneath than usual.
Dirt is very easy to remove, you can forget about washing every other day and choose bright colors.

Minuses:

membrane clothing is quite expensive
requires special care
relatively short-lived
clothes for it must be selected in a special way;
Not suitable for lovers of everything natural.

Types of membranes

The best is the Gore-Tex microporous membrane, developed in the 60s of the 20th century for astronaut suits. For ski clothing, as a rule, two-layer Gore-Tex is used, which is lighter and softer than three-layer, from which jackets for tourism and mountaineering are mainly made.

The water resistance of the two-layer membrane is 15,000 mm, and the moisture evaporation rate is 12,000 g/m2/24 hours.

The non-porous membranes Triple-Point and Sympatex, ULTREX, and other fabrics under the general name hi-pora are kept approximately on the same level with Gore-Tex. Their water resistance ratings are slightly lower - approximately 12,000 mm, but this is quite enough to not get wet even in heavy rain or snowfall. These membranes also breathe very well. Sympatex, in addition to being used in its pure form, is part of the Omni-Tech technology, which includes a membrane, a special water-repellent coating and a windproof layer.

Ceplex and Fine-Tex membranes, which are now very actively used in the production of sportswear, are much cheaper. The main disadvantage of Ceplex is its fragility.

If clothes with Gore-Tex, Triple-Point or Sympatex last 4-5 years with careful handling, then Ceplex rarely withstands more than one or two seasons of active use and begins to get wet. Fine-Tex, on the other hand, does not get wet, but breathes a little better than polyethylene. But these membranes themselves and clothing with them cost an order of magnitude less than their counterparts from Gore-Tex, Triple-Point and Sympatex.

The Ceplex membrane is used in the production of Vaude brand clothing.
Membrane Fine-Tex, Sympatex - in brands Bolik, COOLAIR.
hi-pora membranes - in the brands Commandor (Hi-Pora™/Evapora™), Lowe Alpine (Triple Point Ceramic), Columbia (Sympatex)

Membrane, insulation, outer fabric and weather conditions, let’s sum it up at the layman level by creating review of brands currently represented in Ukraine.

On average, you can start wearing winter membrane clothing from +5+7 °C (for cool children). A membrane overall or set worn by a baby during autumn rain or during a spring thaw will save the mother’s nerves (but not those around her) and will give the child a lot of joy from interacting with water. If no active fiddling around in the puddle is expected, fabric impregnated with DWR will suffice.

It would be very nice if the seams in the product are taped. Reima tec (for cool children, but if the child is active and not freezing, it is better to get by with demi-season clothing), Huppa (jacket without fleece insulation or with 80 g of insulation, fleece-lined trousers) are suitable for such conditions. Under the overalls - a minimum of clothing, ideally - thermal underwear. Because, as practice shows, when there are a lot of puddles around, it is not difficult for a child to walk inactively.

When the thermometer shows 0...-5 °C, you can either add 1 layer, or change outer clothing. As an option - Reima tec (you can add a fleece blouse or a mixed golf shirt to your thermal underwear), Huppa (jacket without insulation on fleece or with an amount of insulation of 80, 130 g, trousers with fleece or bib overalls 100 g), Lenne (products with an amount of insulation no more than 150 g), Bambino, TCM, H&M.

Suitable for temperatures of -5...-15°C are Reima tec (it is advisable to wear thermal underwear or other underwear and a fleece overall under the overalls), Huppa (jackets with insulation amounts of 130, 160, 200 g, bib overalls 100 g, overalls 200 g), Lenne ( products with insulation 150 g, 330 g), at temperatures below -10 °C you can wear a down jacket (O'Hara, Chicco, Geox) or overalls Kiko, Donilo, Gloria Jeans, Lemmi, Shaluny, Gusti, Bambino, TCM, H&M.

15 °C and below - many mothers cancel walks at this temperature. If you are not one of those people, make sure that the child does not sit still on the street (in which case a fur coat will not help much), which means that he is not dressed in thick clothes and can move freely.

15-20 °C will not be scary if the child rides down the slide, sculpts a snow woman, plays snowballs (if you don’t believe me, try it yourself!). Suitable for Reima tec (not for everyone, depends on the child), Huppa (jackets with insulation amounts of 130, 160, 200 g, bib overalls 100 g, overalls 200 g), Lenne (products with 150 and 330 g of insulation), down jacket (O'Hara , Chicco, Geox), overalls Kiko, Donilo, Gloria Jeans, Lemmi, Shaluny, Gustі, Bambino, TCM, H&M.

These recommendations are suitable for small pedestrians. If the baby walks, but still rides in a stroller, you can, after dressing him for a walk, put him in an envelope in the stroller. Then you won’t freeze in the stroller and won’t sweat while running.

For babies in the first year of life, one-piece overalls are well suited - Huppa (200 g), Lenne (baby models or transformable overalls), down jackets (Chicco), overalls Kiko, Donilo, Gloria Jeans, Lemmi, Shaluny, Gusti, sheepskin overalls. You can also choose lighter options, but put a fur envelope in the stroller and enjoy your walk

The membrane resolved a controversial issue. How to get breathable clothes with water-repellent properties. What's the secret? The fact is that each pore of the membrane is so small that it will not allow even a drop of water to pass through, but the pore is large enough to remove steam, which is smaller in structure, from the body. By combining different types of membranes and related fabrics, manufacturers create clothing with unique properties for different applications.

In membrane clothing there are 4 main areas of application:

for cardio exercises (running, cycling);
for mountaineering;
everyday wear, tourism, hunting, fishing;
for classic winter sports - skiing, snowboarding.

It is this classification that narrows the scope of choice for membrane clothing and allows you not to get lost in the sea of proposals. To find out which group of products to focus on, during the purchase, read the manufacturers' catalogs or take advice from sellers. And proceed to the next stage - selecting the optimal characteristics.

Water resistance and vapor permeability

It is water resistance and vapor permeability that characterize the main properties of the membrane. Water resistance is especially important if you plan to exercise in poor weather conditions. It is calculated using special devices that simulate a water column. The more water pressure the membrane fabric can withstand, the better it will protect its owner.

These 2 indicators can be indicated on clothing labels. Water resistance in mm water column, and vapor permeability in MVTR or RET. More about this below.

In some cases, the manufacturer indicates only the scope of application of the product, without specifying MVTR or RET.

Water resistance

The water resistance indicator is grouped as follows:

more than 20,000 mm - clothing is suitable for use during a storm, heavy rain with strong winds;
10000-20000 mm – withstands heavy rain or downpour;
5000-10000 mm – moderate rain;
1000-5000 mm – light rain, fog;
<1000 мм – только ветрозащитные свойства.

Despite the variation in water resistance, manufacturers often offer a membrane with the highest protective properties. In this way, as if guaranteeing their clients comfort during any bad weather.

For lovers of hiking, fishing and hunting, are produced.

Vapor permeability

Vapor permeability in membrane clothing is much more important than water resistance. It is she who is responsible for comfort during active physical activity, when the body produces steam that needs to be removed quickly and efficiently.

To calculate vapor permeability, 2 main methods are used:

MVTR involves testing samples for the fabric's ability to transmit water vapor. The resulting indicator is recorded as X g/m2/24 hours, with an X value of more than 13,000 - extremely breathable clothing, from 6,000 to 13,000 - excellent breathability, below 6,000 - clothing with a moderate ability to release steam.
RET- a reverse technique that calculates how the fabric resists the release of steam. It was originally used by Gore-Tex. The vapor permeability scale according to the RET method looks like this: from 0-6 - nothing prevents the escape of steam, extremely breathable fabric, 6-13 - excellent breathability, 13-20 - fabric with moderately breathable properties, more than 20 - the fabric does not breathe.

Vapor permeability indicators calculated using 2 methods are not always identical. This is due to the testing conditions in different research centers.

In view of this, some manufacturers indicate both values on the tag, others - only an indicator calculated using one method, and others may not give specific values to the consumer at all (in order to avoid comparing clothes with competitors’ products based on only one indicator).

What level of vapor permeability to choose

High vapor permeability rates are especially important for active physical activity. If you plan to wear membrane clothing only while walking, a vapor permeability rating of 6-10 RET is sufficient.

Types of membranes by structure and purpose

The membrane is a very thin film with tiny holes. It is able to transmit steam coming from the body and at the same time remain resistant to humidity from the outside, not allowing even small particles of water to pass through.

This is what membrane tissue with pores looks like under a microscope

The structure of the membrane plays an important role in its operation and even its service life.

What types are there?

Poreless– they work indirectly, since the steam first settles on the inner surface of the membrane and then gradually evaporates under pressure. Poreless membranes are durable and easy to maintain;
Pore– very well “breathable” membranes, but require careful care;
Combined– combines the characteristics of both pore and non-pore membranes. This type is used by all leading manufacturers;
eVent- a new class in membranes, manufacturers have “taught” the pore membrane to repel dirt and fats, thereby giving it greater durability.

Review of druft jacket with eVent membrane

The purpose of membranes also varies:

Windproof– usually work in conjunction with fleece (polartec) fabric, onto which a layer of water-repellent impregnation is applied. Such clothing is optimal for use in the off-season; it warms well and can withstand light rain. All windproof membranes are durable, inexpensive and easy to maintain.
Wind- And waterproof– a classic in the membrane industry. They are designed to operate even during bad weather conditions. They have good water-repellent and windproof properties, while maintaining the ability to breathe. These membranes are expensive and difficult to maintain.

Membrane Protective Fabrics

The membrane (due to its thinness) in clothing is always covered by fabric, which must first withstand the impact of wind, rain or snowfall.

The inner lining is in the form of a mesh that protects it.

Its properties are influenced by the following indicators:

Fiber type- These are synthetic materials nylon or polyester. They have approximately the same properties, but nylon is more durable, and polyester is cheaper and warmer. In rare cases, elastic materials are used in membrane clothing, since the membrane is very sensitive to stretching.
Thickness and weight of threads– this indicator is designated as Den or D (denier) and is calculated as the weight of 9 km of the designated thread. High denier fabrics are very durable and quite heavy.
Density– calculated in g/m2. High rates always characterize heavy, dense fabric.

Every manufacturer is always looking for the ideal light, durable and at the same time inexpensive fabric. But in practice, you always have to look for a compromise between the weight of the product and strength.

If you are not planning to conquer mountain peaks, but are choosing clothes to wear in city mode or short hikes, inexpensive membrane jackets are quite suitable. They have sufficient density, moderate weight and reasonable price.

For mountaineering and freeride Only ultra-strong and lightweight materials are suitable, which are tested for resistance to friction and tearing. These fabrics are very expensive, which affects the final cost of the products.

If you are doing long hikes, make sure that the membrane jacket is wear-resistant, since the backpack straps create friction during movement and can damage both the fabric itself and the membrane.

For aerobic exercise Lightweight fabric with moderate strength is ideal. However, it is advisable to move in such clothes on terrain without obstacles.

Methods for connecting membrane to fabric

In order for the membrane and fabric to work together, they are connected. Outer fabric - membrane - inner lining. It turns out to be a kind of sandwich.

How does it work:

2-layer materials (2L or 2-layer) - obtained by simply attaching a membrane to the inside of the fabric. This method has a significant drawback - the membrane wears out quickly, since it is not covered with anything from the inside. Sometimes manufacturers add a conventional 3rd layer in this scheme - a lining in the form of a mesh or soft fabric, but it does not serve as full protection for the membrane.
2.5-layer materials (2.5L or 2.5-layer) are very similar to 2-layer materials, only the function of covering the membrane is not performed by a mesh, but by a special coating. This membrane fastening scheme allows maintaining the flexibility and durability of the membrane.
3-layer materials (3L or 3-layer) are a kind of monolith of fabric, membrane and lining. Clothing with this type of membrane fastening is quite heavy and inflexible, but benefits from a long service life.

A brief educational program on labeling fabrics with heat-saving properties

Designations:

Soft Shell - especially soft, comfortable, flexible material;
Windbloc, Windtec - products with these designations provide excellent wind protection, but do not guarantee water-repellent properties;
Windstopper - an improved line of clothing from Gore with good wind protection;
Polartec Thermal Pro is a good warming material, essentially a slightly improved Polartec;
Polartec Wind Pro - warming material with excellent windproof function, can protect against light rain;
Polartec 200 is one of the most popular heat-saving materials for jackets;
Resist Techno Soft Shell is the latest material on the membrane clothing market, provides excellent warmth and has increased breathability. Suitable for active sports;
Rip Stop is a fabric with a special weave structure, therefore durable and wear-resistant;
Gore-Tex is the world's first patented membrane;
Sympatex is a German high-tech membrane that is used in clothing and footwear;
eVent is an advanced pore membrane, ideal for clothing for extreme sports;
ComforTex is a membrane from an Italian manufacturer with wind- and water-repellent properties.

Pay attention to the cut features

Manufacturers are no less scrupulous about the sewing process than they are about the selection of fabric and membrane type. If the model does not fit perfectly, the whole point of membrane clothing will come to naught.

At the first stage, fashion designers prepare a pattern. It should take into account the main nuances of future physical activity. Everything is important here: from calculating the seam allowance to the width of the elastic bands on the cuffs.

For greater functionality in clothing, the areas most susceptible to wear are sealed, making the base of the product from lighter materials. This allows you to reduce the cost while maintaining the quality and lightness of the finished garment.

On overalls and trousers, the bottom of the legs, knees and buttocks are sealed. In jackets, thickening is done on the elbows, cuffs, and shoulders. It is membrane clothing that is characterized by shifting shoulder and back seams - this allows you to reduce the friction of the backpack during long hikes.

In general, membrane clothing is not the place for modeling frills, so manufacturers produce 3 main types of cut:

Athletic– designed for intense physical activity (running, cycling). Assumes an ideal fit to the figure (it, accordingly, should also be fit). Clothing of this cut follows the curves of the body as closely as possible; under it you can only wear thin thermal underwear and a fitted fleece jacket.
Regular cut is more versatile. It allows you to wear thermal underwear and a second, denser insulating layer. It is comfortable to wear this type of clothing for a long time; it does not restrict movement. Suitable for hiking, walking and other light activity.
Loose fit designed specifically for use in unstable climates. Under such clothes you can wear a different number of insulating layers. It is suitable even for people who do not have an ideal physique. But the main purpose of a loose cut is to be used during expeditions, long hikes and for low-impact sports.

All the subtleties are in the details. An important point when choosing

Membrane clothing is a kind of standard in textile production. She does not tolerate crooked stitches and especially poor fittings. But for its good functionality, a “reliable rear” is needed.

What to look for when choosing. Using the example of a review of The North Face Men Tethian jacket

Sealing seams

Any sewing needle leaves holes in the fabric. And if no one pays attention to them in ordinary clothes, then in membrane clothes moisture can leak through these holes. To eliminate this defect, in all models the seams are sealed, i.e. The top is glued with a special tape.

Ventilation

During active movement, the body quickly heats up. In order to remove the generated heat (steam) as efficiently as possible, manufacturers provide additional ventilation. On jackets in the armpit area, and on trousers along the inner seam, zippers are sewn in. Sometimes an additional folding pocket can serve as additional ventilation, which, however, is only appropriate in lightweight models.

Hood

The upper part of the jacket is one of the most vulnerable places in the entire complex of membrane clothing. The hood should provide protection here. For driving in normal weather conditions, models with a simple cut are suitable. They can handle moderate rain and snow quite well. During extreme travel and mountain hiking, the hood should fit well to the helmet. To do this, it is given a more complex shape and several adjustments are provided.

Lightning

The accessories used in membrane clothing are of the highest quality. Despite the fact that in good zippers the teeth fit together as closely as possible, in heavy rain conditions they can also become vulnerable. In budget clothing, zippers are hidden under a fabric strip for additional protection. In more modern and expensive models they are treated with a special polymer. It prevents water from seeping inside, as it tends to repel it.

Be sure to check all zippers (not just the main ones) before purchasing.

Changing snakes (runners) in membrane clothing is very difficult, since during repairs the tightness of the seams may be compromised and the product will lose its properties.
Check whether it is easy to fasten the zipper while wearing gloves. If it grabs the fabric, be sure to put the item aside. “Playing” with bad lightning during bad weather is not a pleasant experience.

Pockets

These elements in membrane clothing should be both comfortable and functional. Consider what you will need in an easily accessible place and whether the pockets meet these requirements.

The above features of such clothing are the main ones, but not the only ones.

There are other additional options:

Fleece inserts on the inner surface of the jacket/pants provide additional protection for the membrane;
a flexible visor on the hood will cover your face from wind, rain or snowfall;
snow skirt - for severe cold weather and mountaineering, it is not just an additional option, but another main factor of protection.

Who produces

When choosing membrane clothing, the last thing you should pay attention to is the price of the product. By the way, it can be both transcendental and more democratic. It all depends on the “renowned” manufacturer, the quality and type of membrane, the characteristics of the top layer of fabric, etc.

The most famous manufacturers of such clothing:

The North Face is an American brand widely known throughout the world. The company's developers were directly involved in improving the Gore-Tex membrane. One of the main areas is clothing for mountaineering. Now the company's product list includes almost the entire arsenal of things for sports and tourism.
Marmot is a North American company with over 50 years of experience. Produces clothing with a PreCip membrane.
Black Yak, a company originally from Korea, confidently occupies key positions not only in the Asian market, but throughout the world. The main direction is clothing for mountaineering.
Arcteryx - this Canadian brand is well known to all extreme athletes. The company has many years of experience, established itself in the last century and confidently holds its own in the market.
Norrona is a European brand that was the first to release a jacket with a Gore-Tex type membrane. One of the most recognizable companies in Scandinavia.
Decathlon is a French manufacturer of budget sports equipment. Models are easy to select thanks to the available classification. Before going on sale, all products are tested, so the buyer can be confident in the quality of the product. The price of membrane clothing from Decathlon is one of the most affordable.

How to wear it correctly

Membrane clothing suggests the presence of allies. To begin with, it's right. It must correspond to the type of physical activity. If thermal underwear does not cope well with moisture removal, the operation of subsequent layers is also at risk.
The second layer of clothing - also insulating - should work in conjunction with thermal underwear and membrane clothing. Choose a fleece jacket or jumper in accordance with the temperature conditions. If necessary, wear not one, but 2-3 layers (). The membrane clothing itself is the final, 3rd link in the overall complex.

Remember: only a well-thought-out set of clothes will not spoil the overall impression of wearing things with a membrane. If you feel cold or, on the contrary, overheat, try changing your thermal underwear or a second layer.

Having bought membrane clothing, be sure to. This way you will extend the life of things and thereby minimize one of the main disadvantages of the membrane - high cost and fragility.

Membrane clothing has both a large number of its adherents and those who do not recognize it and trust ordinary things. The former are always up to date with new products, and the latter are lured by manufacturers with interesting cuts, bright combinations and even promotional offers. So, this type of clothing is gradually gaining a place in the market, in our closets, and it does so more than confidently, because it is not afraid of either fashion trends, global warming, and especially the weather in the house.

(in everyday speech sometimes called simply membrane ) is a type of fabric that, due to its special structure, has water-repellent or windproof properties and at the same time allows water vapor to pass through it.

The membrane fabric consists of several layers: an upper wear-resistant layer and a lower soft layer. And between them there are several protective layers of fabric and membrane .

The first industrial membrane fabric was Gore-Tex, developed for use in space by Rowena Taylor, Wilbert L. Gore and his son Robert W. Gore. It was initially protected by a patent, but after the patent expired, other types of fabrics with similar properties appeared on the market.

Membrane fabric has found wide application in tourist products: it is used to sew jackets , trousers, do shoes. The reason for the success of this type of fabric is that the membrane fabric allows you to stay dry in the rain, while the body does not dry out due to lack of air.

What is a membrane?

The membrane is either the thinnest film that is laminated (welded or glued using a special technology) to the upper fabric, or a special impregnation that is rigidly applied to the fabric using a hot method during production. On the inside, the film or impregnation can be protected by another layer of fabric.

This is a fabric that has windproof and/or waterproofing properties, while the normalized pore size of the membrane allows the material to effectively allow the evaporation of the human body to pass through (breathe). The opposite of it is the so-called. “Oilcloth”, that is, a completely non-breathable fabric with a polyurethane (PU) coating, usually used in the production of tents and awnings.

Membrane fabric is used in top layer clothing, protecting the lower layers of clothing from getting wet. The structure of the membrane fabric allows your skin to breathe and remove sweat. The higher the technical characteristics of the membrane fabric, the stronger and lighter it is in weight.
Double layer fabric– this is the outer layer of fabric, to which the wrong side is applied in a special way. membrane. This fabric is always used in products with a lining, because... the lining provides adequate protection to the membrane from clogging and mechanical damage.
The three-layer fabric looks like a fine mesh fabric on the reverse side. This is the upper fabric + membrane+ knitted mesh, glued into one structure using a special lamination technology. The knitted mesh protects the membrane from mechanical damage and clogging.
“Two-and-a-half” layer membrane fabric is a material developed using new technology. This is a two-layer membrane fabric, coated on the inside with a protective layer (foamed protective coating in the form of pimples), which performs the functions of the third layer, i.e., protecting the membrane. Cloth This fabric makes it as light as possible and does not need lining, and the weight of the protection is much less than that of three-layer materials.

In the production of modern high-tech clothing, they use membrane materials based on expanded polytetrafluoroethylene. By physically deforming Teflon, a thin porous film is obtained, which is applied to fabrics and used in sewing clothes.

Theoretically, such fabric will allow you to stay dry in the rain, but at the same time the body will not sweat due to lack of air. Membrane fabrics are widely used in outdoor activities because they are, unlike conventional waterproof fabrics (with PU coating).

In clothes made of membrane fabric, you can walk in any weather, except the hottest humid weather, without experiencing discomfort. The technical characteristics of membrane fabrics are compared in accordance with the mentioned properties: which material breathes better, which is stronger, etc. “Breathing” depends on the vapor permeability of the membrane (measured in g/sq.m for 24 hours) - the greater the permeability of water vapor, the better the material “breathes”. What is the principle of operation of membranes? They have a chemical structure in the form of a film with pores several thousand times smaller than a drop of water, but larger than an H2O molecule. Therefore, the drop simply does not pass through them. This ensures waterproof. But water vapor molecules pass through the pores freely. When sweat appears (during hard work), a difference occurs in the partial pressure of water vapor under the jacket and outside. This is the driving force for the removal of steam, which is discharged outside. Such membranes are called microporous.

The technical characteristics of membrane fabrics are compared in accordance with the mentioned properties: which material breathes better, which is stronger, etc. Waterproof determined by the water column pressure that a fabric with a membrane applied to its surface can withstand for a certain time - the more it can withstand, the better. In a jacket that “holds” more than 6000 mm, you can walk in the rain (8000 mm - you can safely work in a downpour, 10000 mm - jacket waterproof).

To ensure that microporous membranes last longer, you need to wash your clothes with special detergents. In clothing that uses this type of membrane, the top layer of fabric itself must have good water-repellent properties. This is because if the outer fabric gets very wet, membrane will allow water to pass through (due to the fact that inside the fibers of the upper material the surface tension force is much weaker and water drops as such are not formed). Therefore, it is necessary to restore the water-repellent properties of the fabric. In addition, no membrane will “breathe” if there is a continuous film of water or a layer of ice on the surface of the fabric. Therefore, restoring the water-repellent properties of the top material is important for all types of membrane materials.

STRUCTURE OF MEMBRANE FABRIC:

The size of the membrane pores does not exceed the size of water molecules, which eliminates water seepage inside, due to the fact that the pores are 20 thousand times smaller than a drop and 700 times larger than a water molecule.

In the form of vapor, molecules not bound by surface tension in the gaseous state easily pass through the membrane.

The tunnel-like structure of the pores breaks the air flow into micro-eddies and acts as a barrier to the wind (much like a dense bush), without interfering with single molecules of water vapor (or gas, if you prefer).

Classification

The world classification allows us to divide all membrane tissues into several classes:

Membrane categories by structure

Based on the structure of the membrane, fabrics are divided according to the principle of which one is used: non-porous, porous and combined.

Poreless membranes work on the principle of osmosis. The system is as follows: vapors fall on the inside of the membrane, settle on it and, through active diffusion, quickly move to the outside of the membrane. (Again, only if there is a driving force - a difference in the partial pressures of water vapor). What are the advantages of non-porous membranes? They are extremely durable, do not require careful maintenance, and work properly in a wide temperature range. Such membranes are usually used in top-end (expensive and most functional) products. What are the disadvantages? At first it may seem that the products are getting wet, but this is precisely the same fumes that accumulate on the inside of the product. That is, they begin to breathe more slowly, but advanced non-porous membranes, “heating up”, sometimes surpass porous membranes in their breathing properties.

Pore membranes- these are, roughly speaking, membranes that work according to the following principle: drops of water that fall on the membrane tissue from the outside cannot pass through the pores of the membrane inside, since these pores are too small. The steam molecules that form when you sweat are freely removed from the inside of the membrane tissue through the pores of the membrane (since a steam molecule is thousands of times smaller than a drop of water, it can freely penetrate through the pores of the membrane). As a result we get waterproof membrane fabric on the outside of the product and breathable (steam-removing) properties from the inside of the product. What is the advantage of pore membranes? They “quickly” begin to breathe, i.e., they remove evaporation as soon as you start to sweat (provided that there is a difference in the partial pressures of water vapor inside and outside jackets. That is, when there is a driving force). What are the disadvantages? This membrane “dies” quite quickly, that is, it loses its properties. The pores of the membrane become clogged, which greatly reduces the breathability. If washed incorrectly jacket may start to leak. This drawback can manifest itself especially strongly if you are not a particular fan of caring for your things (using special DWR sprays, detergents for membrane fabrics, etc.).

Membrane combination– the upper fabric is covered on the inside with a pore membrane, and on top of the pore membrane there is also a thin coating (i.e., a non-porous polyurethane membrane film). This magical fabric has all the advantages of pore and non-pore membranes without the disadvantages. But high technology comes at a high price. Very few companies use this membrane in their products...

By design, membrane fabrics are divided into: two-layer, three-layer and so-called “two-and-a-half”-layer.

A two-layer fabric is a top fabric, to which a membrane is applied (in a special way) on the reverse side (in the picture it’s white, but it can also be transparent or with some other pigment). This fabric is always used in products with a lining, because... the lining provides adequate protection to the membrane from clogging and mechanical damage.

The three-layer fabric looks like a fine mesh fabric on the reverse side. In essence, it is a top fabric + membrane + knitted mesh, glued into one structure using a special lamination technology. Why do you need a knitted mesh from the inside out? It protects the membrane from both mechanical damage and clogging. And, most importantly, in three-layer products, the use of lining is eliminated. As a result, we have: mega-light fabric + mobility + small volume of the product and maximum functionality. But this is no longer a small amount of money... However, depending on who it is, for some people, comfort is most important, and recently there are more and more such people. The domestic snowboarder is getting smarter... And his wallet is getting stronger.

“Two-and-a-half” layer membrane fabric- This is a new product on the market. Typically, this is an ordinary two-layer membrane fabric, covered on the inside with some kind of protective coating (foamed protective coating in the form of pimples, or knitted pimples, etc.), designed to perform the function of the third layer, i.e., protecting the membrane. But such jackets are made as light as possible - no lining is needed, and the weight of the protection is much less than that of three-layer materials.

Classification of membranes by purpose:

Windproof membranes

Typically applied to a thin fleece fabric, providing a combination of warmth, breathability and wind resistance. Unlike regular fleece, this fabric holds up well to the wind and keeps you warm even when wet, and dries very quickly under active loads. The fabric may have a water-repellent finish to withstand light rain. - the most widely used windproof membrane. The membrane is not very expensive and can withstand many washes. This fabric is the best option for demi-season cycling clothing: cycling pants, gloves, strip on the ears.

Representatives:

Advantages:

Advantages:

Not blown through
Don't get wet
Allows high physical activity

Flaws:

High price
Degrade over time
They don't like washing

About gluing seams

Taped seams prevent moisture from penetrating through the seams, and, as a result, you feel dry and comfortable.

First let's talk about seams in three-layer products. In these products, the seams must, I repeat, all must be taped! This is a standard recognized by all manufacturers! Usually, you can find out about this by reading the inscription on the product tag: “all seams are sealed,” which translated from English means “all seams are taped.” But, anyway, look carefully and check that all the seams on the three-layer product are taped. I would like to note that some particularly relaxed companies sin by not gluing some seams in products made from three-layer fabric, which is a shame and a huge drawback. The next condition regarding three-layer clothing is the minimum number of seams. The more seams, the more weight, the more knots for gluing, the less mobile the product. In three-layer products, all these parameters are extremely important, because the price of these products is quite high and it is implied that the products are the most high-tech.

Currently, most companies use waterproof dry zippers in three-layer products. Using dry zipp eliminates the need for flaps or protective strips on pockets and ventilation, which again saves weight and improves product mobility. In good products, at the top of the dry zipper zipper there is a so-called zipp garage (protection of the lock in the zipper - “garage” for the lock). In the absence of such a “feature,” water will flow into the product through a small hole at the top of the zipper.

Cloth from two-layer membranes. Regarding seams: the inscription “all seams are sealed” means that all seams in this product are taped. If the label says “critical seam sealing,” this means that only the main seams are taped in the product, which may or may not result in leaks in some places. It is worth noting that in products positioned by the brand as semi-cable or semi-urban, this option is very acceptable (usually these are products with insulation). Here, every buyer is free to choose what he wants and what is suitable for him personally. If you spend a lot of time just hanging out with friends on the slope, then probably things with not fully taped seams and insulation will suit you. You can see what taped seams look like in two-layer clothing in the photo.

About membrane fabric manufacturers

Typically, in top-end, three-layer or two-layer items, reputable brands use membrane fabrics produced by companies such as W.L. Gore and Associates, Inc. ( USA) (Gore-tex, Gore-tex XCR, etc.), Toray ( Japan ) (Dermizax, Entrant HB), Event ( USA, produced in Japan), Unitika (Japan). These are leaders in the field of membrane fabric production technologies. Note, countries with a high level of technology!

Approximate figures

Waterproof high-end fabrics are usually at least 20,000mm water column, and breathability is at least 8,000g/m?/24 hours. Mid-range membranes typically have a rating of 8,000mm/5,000g/m?/24hrs or so. The base level is usually 3,000mm/3000gsm/24h, although in products made from this type of fabric, the low performance of the membrane can be well combined with the presence of a large number of ventilation holes, allowing you to regulate the temperature inside the product.

Water-repellent coating – DWR

Look - the droplets on the fabric are not absorbed, but lie on the fabric, rolling into balls! This DWR(Durable Water Repellence) a coating that prevents water from passing even through the top layer of fabric (that is, being absorbed into it). On fabric with DWR coated with water, rolls into balls and rolls easily. DWR, by the way, the thing is not durable, and disappears over time (washed off), and wet spots appear on the fabric (upon contact with water). This does not mean at all that the product will get wet, since it will still not let water through, but some discomfort may be present. The resulting layer of water on top will not allow the membrane to work, no matter how cool it is. In addition, in pore membranes, in this case, water can pass through the membrane. Specially developed products with this same DWR coating will help you avoid dying DWR ( NIKWAX, for example), sold in extreme clothing stores.

About the texture of the fabric

Rip Stop– usually used for top-end, expensive clothes. This is the name of the method of weaving fabric, which in its structure resembles a mesh or honeycomb. That is, this texture uses both thin and thick threads, which makes it possible to produce durable and, at the same time, lightweight material.

Twill weaving also often used in snowboard clothing. This is a smooth material that is pleasant to the touch (see photo of the previous section) and has excellent strength characteristics. In the last couple of years, many, especially advanced brands, began to present denim clothes with a membrane in their collections.

Types of membrane fabrics

SOME TECHNOLOGIES FOR PRODUCTION OF MEMBRANE FABRICS.

Omni-Tech Mini-Faille FD Ceramic
A technology in which the inner surface of the fabric (durable, textured, with a matte finish of 100% nylon) a layer of microporous polyurethane is applied, into which ceramic particles are embedded, which give the fabric strength and are additional micropores, too small for moisture from the outside to penetrate through them, and large enough to allow moisture vapor from the body to pass out. Water permeability is 11900 mm, the ability of the fabric to “breathe” is 8400 g/sq.m./24h.
Omni-Tech Storm Dry Coating
Fabric, the base of which is coated with a layer of matte nylon microporous polyurethane, and the inner surface of the fabric is coated with a waterproof coating. Water resistance 5500mm, fabric breathability 5700 g/sq.m./24h.
Scholler-Comfort-Temp
This technology provides special linings on the inside of jackets, consisting of wax microcells and regulating the temperature microclimate for the body.
Sympatex Transactive
This technology provides an increased level of comfort for people involved in active sports. A completely new membrane fabric system consisting of a membrane Sympatex and a water-repellent layer, eliminates sweat not only in the form of evaporation, but also in the form of moisture. Due to its structure, it is poreless Sympatex Transactive ensures that the skin's breathing will not be impeded by dirt, salt crystals, detergent particles and other external factors.
Sympatex Professional
Tightly connected seams ensure 100% waterproof. Extreme climatic conditions in winter require maximum functionality and efficiency. This is achieved thanks to two- and three-layer materials, tightly connected to each other so that they provide 100% waterproof .
Pontetorto Dryfast
Anti-odor and anti-moisture technology. An exceptionally light knit that allows sweat to quickly wick away thanks to the capillary properties of the material. Keeps the body dry. Antibacterial material, which has also been processed using a special disinfectant technology and as a result constantly neutralizes bacteria that cause unpleasant odors.
Schoeller Stretch, Schoeller WB400
Elastic, windproof and comfortable to wear. Elastic three-layer material Schoeller WB400 is three fabrics in one. The outer layer, made of elastic and synthetic fibers, guarantees complete freedom of movement and protection from dirt. The waterproof second layer allows sweat to evaporate. A dense, voluminous inner layer with a fleece that retains heat makes it comfortable to wear.
In clothes made of membrane fabric, in any weather, except the hottest humid weather, you can walk or run, climb rocks, ski and not experience discomfort. In Soviet times, climbers and tourists had to wear canvas rain jackets, which quickly became wet and were quite heavy compared to modern membrane jackets. In the 70s, when Russian climbers came to visit their American colleagues, they gave the guests a tent with awning membrane Gore-Tex. Russian climbers could not believe it for a long time: how could it be that in the heaviest rain awning doesn’t get wet, and the steam from a pot boiling on a primus stove evaporates freely through the tent awning?! Membrane fabrics are compared in accordance with the mentioned properties: which material “breathes” better, which is stronger, etc. Water resistance is determined by the pressure of the water column that the fabric with the membrane can withstand for a certain time: the more it can withstand, the better. In a jacket that “holds” more than 6000 mm, you can stay in the rain for some time, 8000 mm - you can safely work in the downpour, 10000 mm - jacket waterproof.
“Breathing” depends on the vapor permeability of the membrane (measured in g/m2 for 24 hours) - the greater the permeability of water vapor, the better the material “breathes”. Often, when purchasing, there is a mistake in selection due to the fact that different membranes have been tested differently. Let's assume that two companies in their advertising materials indicate a water vapor permeability of 5000 g/m2 for their fabrics. But one was kept over a flask of boiling water, and the other at a water temperature of 36.6°C. It is clear that the results will be different, and that the fabrics “breathe” differently. In Europe, ISO 811 tests are generally accepted (for waterproof), ISO 9237 (for wind resistance) and ISO 11092 (for vapor permeability). However, American, English (BS7209 WVP Index) and other European tests are very different from each other.

Dermizax: Combines full waterproof and moisture removal with increased strength without compromising the smoothness and softness of the material. Water resistance remains at the same level, regardless of the energy and intensity of movements. The ability of the fabric to “breathe” and remove moisture is ensured by a unique non-porous membrane. At the same time, the “breathing” properties of the membrane can increase with increasing human body temperature. This results in an increase in the distance between the membrane's long molecular chains of polymer, making it more accessible to water vapor molecules. Keeping condensation to a minimum prevents the inner layer from freezing and effectively complements the fabric's breathability. The membrane does not collapse with numerous washes, which makes it easy to care for. Water resistance 2000mm, breathability 10000 g/sq.m/24h.

Those. the distance between molecules is fundamentally greater than a water molecule and less than a drop of water, and with increasing body temperature these distances increase even more. The result is a membrane material that, with active movements, simply releases more steam onto the surface of the clothing while maintaining the normal thermal balance of the body. And therefore the comfort of the state. Water resistance 20000mm, vapor permeability 15000gr/sq.m/24h.
Isotex: The fabric is 100% windproof and the outer surface is coated with a water-repellent coating. It is a hydrophilic material, i.e. it consists of chains of molecules that conduct moisture and water through the fabric. When water molecules get caught between these chains, the molecules swell and their ability to conduct moisture and water increases.
Kevlar: Highly strong and durable material. Highly resistant to tearing, Kevlar 5 times stronger than steel when compared on a weight-for-weight basis.
Koliv: The coating collects moisture and releases it into the atmosphere, generating heat. This thermal energy allows moisture to be quickly removed to the surface. As a result, the “breathing” properties improve and almost no moisture remains on the inside. Vapor permeability 20000 g/sq.m/24h.

Outlast: Microthermal material embedded in fabric, which consists of millions of microcapsules that can absorb heat emanating from the body when heated, distribute it evenly and return heat when cooled. If the body temperature rises, then Outlast takes on a certain amount of heat, restoring thermal equilibrium, and, at the same time, changing the phase to liquid (melting). When body temperature drops without movement and the body becomes cooler than the tissue, heat is transferred back to the body, restoring thermal balance. And Outlast changes the phase to solid. Thus, Outlast not only retains heat, but also removes excess heat, while maintaining body temperature comfort.

Sympa Tex: A waterproof and vapor-repellent membrane used as one layer in multi-layer materials.
2-ply Sympa Tex: A two-ply material consisting of an outer fabric (Stretch is often used) and a SympaTex vapor-permeable waterproof membrane. Water resistance 15000mm, vapor removal g/sq.m/24h.
3-ply Sympa Tex: Three-layer material consisting of a dense and lightweight fabric exterior, a waterproof and vapor-wicking SympaTex membrane and a hygroscopic micro-mesh lining. The membrane collects released moisture and removes it from the body, while maintaining the body's thermal balance. Water resistance 30000mm, vapor removal 700 g/sq.m/24h.
mSM 2.5 SympaTex: This is a microstatic membrane, the development of which has achieved the following properties - lightness of the fabric, increased absorbency properties on the inner surface and a thicker layer of internal air layer. As a result, an air gap was formed, which improved thermal insulation by 30%, and many zones of a clean membrane were formed in which condensation could accumulate without any points of contact with the body. The main difference between this material and the three-layer 3-ply SympaTex is the structure of the weaving of the fibers; they are located not parallel, but perpendicular to the surface of the membrane, which creates an air gap; in addition, the vertical fibers improve the absorption of moisture and its removal to the membrane for release to the outside.
Super Microft: 100% polyester , waterproof 2000mm, vapor permeability 9000 g/sq.m/24h.
Supplex: The fabric does not fade and is breathable. Saplex was developed by DuPont
Windbloc: A special membrane makes this fabric waterproof, windproof, yet breathable. The fabric is quite light and does not restrict movement.
Windstopper: Waterproof membrane material, 100% polytetrafluoroethylene (Teflon). By deforming Teflon, a thin porous membrane is obtained. It retains heat while removing excess moisture into the atmosphere, maintaining body comfort. The membrane is used as an additional layer between the lining and the top layer of knitted garments, marked Windstopper .
Windstopper Flees: Soft, thin material, with the addition of an additional layer of membrane, which provides improved thermal performance and high breathability. The membrane retains heat well. The material is twice as warm as regular material fleece, prevents heat loss and increases the feeling of comfort.

XT 10000: Water resistance 10000mm, breathability 8000 g/sq.m/24h
XT 20000 3 Layer: Waterproofness 20000mm, breathability 4000g/sq.m/24h
XT: This coating penetrates the fabric in such a way that the structure of the fabric becomes like a honeycomb - with many micropores. These pores are too small to allow water particles to pass through (this makes the fabric waterproof), but large enough to allow moisture from the body to pass through (this allows the body to breathe).
XT.L: XT.L Laminate is an ultra-thin membrane that provides an exceptional degree of water resistance while allowing the skin to breathe. This membrane also provides the fabrics with a high level of elongation, which serves as a guarantee against damage to the membrane even after prolonged intensive use and frequent washing.

Durability and efficiency

Typically, the durability of wind barrier membranes is limited by the strength and wear resistance of the base material. With careful use, the fabric can withstand many washes for several years without losing its properties.

In the case of waterproof membranes, the situation is worse. It is believed that the service life of a good expensive membrane is several (2-3) years, and with each wash the waterproof properties deteriorate. After the water-repellent layer is washed off, the fabric becomes covered with a film of water in heavy rain and does not breathe much better than a regular raincoat.

After several years of active use, even Gore-Tex begins to get wet through in the heavy rain. However, this is also true for ordinary oilskin jackets, under the same operating conditions. The degradation of properties can be slowed down by periodically treating an old jacket with a special impregnation, but this is not a panacea; it will still get damp in the rain.

PROS AND CONS OF MEMBRANE CLOTHING

It is light and comfortable;
Protects well from rain and snow, durable and lightweight;
It is not blown by the wind and removes body fumes well;
It is suitable for both not very cold weather and frosty ones;
Dirt is very easy to remove, you can forget about washing every other day and choose bright colors.

Minuses:

WASHING CLOTHES MADE FROM MEMBRANE FABRICS

Clothes made from membrane fabrics cannot be washed with ordinary detergents. Washing powder clogs the porous structure of the membrane, which leads to the loss of its specific qualities. In this case, the membrane stops “breathing” - its breathability properties decrease. The same thing happens when using conditioners and bleaches.
Detergents containing chlorine and its derivatives have the opposite effect of clogging the pores of membrane fabric. Chlorine molecules have a perforating effect on the membrane, due to which it begins to “breathe” better, but, as a result, gets wet. Thus, the water-repellent protective properties of the membrane fabric are reduced.
It is recommended to wash using special DWR sprays, detergents for membrane fabrics, etc.). Otherwise, you can wash it using liquid soap or baby shampoo.
Membrane clothing should never be washed in a washing machine, should not be soaked, or wrung out. This also has a negative effect on the specific properties of the membrane tissue.
No soaking of the product is required. As a rule, fabric stains can be easily removed by hand washing. To avoid damage to the membrane, wash by hand at a temperature of 30-40 degrees. After washing, the product is wrung out by hand, but without twisting. To remove excess moisture, you can use a highly absorbent cotton cloth.
Drying membrane fabric products
Membrane cloth dried flat in a horizontal position at room temperature. The room in which drying is carried out must be ventilated. Avoid direct sunlight to avoid fading of the top layer of membrane clothing.

SPECIAL CARE

Membrane clothing should never be ironed, as high temperatures can damage the structure of the fabric.
To restore the water-repellent properties of the outer fabric of membrane clothing, use a special fluoride-based spray. Fluoride compounds make it possible to create a water-repellent film that will not impede air movement. In addition, the film will make it difficult for external contaminants to penetrate and increase the fabric’s resistance to ultraviolet radiation.

IMPREGNATION OF MEMBRANE CLOTHING

Membrane materials needs to be soaked from time to time. Various special aerosols or washing liquids are suitable for this. It must be remembered that only CLEAN items need to be soaked after washing or cleaning. For different fabrics it is possible to use only your own products. The use of aerosols and impregnation liquids may cause slight discoloration of clothing. Regular use of impregnations will entail maintaining the good water-repellent properties of the membrane.

STORING CLOTHES MADE FROM MEMBRANE FABRICS

Membrane clothing is stored flattened and in a vertical position. To prevent dust from entering the porous structure of the membrane, clothing made from membrane fabrics should be placed in a protective fabric or polyethylene shell. Before storage, the membrane must be washed in accordance with the recommendations.

What is a roofing membrane

The membrane is a film roofing material consisting of polymers, which can be based on thermoplastic olefins, synthetic rubber or plasticized polyvinyl chloride. However, it is impossible to name the exact components, since each manufacturer uses its own specific components. Fiberglass, modified bitumen, various plasticizers, etc. are added to the material.

In addition, this is the most modern type of coating, the prevalence of which is due not only to its excellent technological characteristics, but also to its long service life. Thanks to excellent adhesion, excellent waterproofing properties, resistance to moisture and high strength, the material can be widely used in individual construction.

Modern membranes are highly resistant to moisture, durable and able to withstand sudden temperature changes.

Types of roofing membranes

If a membrane is intended to be used for roof installation, then before carrying out work it is necessary to study the types of this material depending on its composition and purpose.

Classification of roofing membranes by manufacturing method

In the production of roofing membranes, several types of polymers and binding elements are used. The result is coatings with different properties, each of which has its own advantages and disadvantages.

EPDM membranes

The EPDM membrane is the first polymer material that has remained popular for half a century. It may be based on a rubber sheet or polymerized special components. To make the membrane stronger, a polyester-based reinforcing mesh is used. In turn, the ether fiber gives the membrane resistance to various mechanical influences. The advantages of such a membrane include:

environmental friendliness;
waterproof;
low cost;
compatibility with most materials, even bitumen;
possibility of use in different climatic conditions and with strong temperature changes;
UV resistance;
flexibility.

The main disadvantage of EPDM membranes is the seams, which are connected to each other using glue, which makes the material less durable and reliable compared to products where joints are provided by welding.

The moisture-proof EPDM membrane is an inexpensive, durable coating that is laid in a joint with gluing of the joints of the sheets

TPO membranes

In the 1990s, the TPO membrane was developed in the USA, which today is the most airtight material among all similar products. This membrane is produced based on olefins that are resistant to high temperatures. Then it is reinforced with fiberglass or polyester, but there are models without reinforcement. The combination of polypropylene with rubber gave the material the characteristics of plastic and rubber, which had the best effect on its compatibility with any other bitumen coatings. Among the main advantages of TPO membranes are the following:

environmentally friendly, since there are no volatile components;
resistance to temperature changes;
durability;
tightness of the connection;
low price;
frost resistance;
Can be used on any type of roof;
high strength, since during the manufacture of the product various stabilizing elements and antioxidants are added to the composition.

The disadvantages of the membrane are low elasticity, especially when compared with EPDM and PVC materials, as well as the need for frequent repairs and timely maintenance.

TPO membranes have high levels of tightness and strength, but are often deformed and require periodic maintenance

PVC membranes

PVC membranes are very popular due to their low price and ease of installation, but they are not compatible with all materials and are susceptible to exposure to chemically active substances

Types of roofing membranes by purpose

Flexible membranes can be used to create different layers of roofing pie on all types of roofing structures.

A vapor barrier membrane is a polymer film that is designed to protect the roofing pie from warm, humid air escaping from living spaces. Thanks to this material, the service life of any structure is extended. The vapor barrier membrane is made of polyethylene of different densities.

It contains antioxidants and other components that increase the technical and operational properties of the coating. The thickness of the material is generally from 0.5 to 3 mm. The material is effectively used for both internal and external roof installations.

Among the advantages of vapor barrier membranes are:

Easy to install. The membrane is secured with staples or soldering. For the roof, the second option is usually used, since when the seams are sealed, a continuous vapor barrier coating is formed.
Low price. The material is affordable, and the technology for its installation will allow all stages of work to be completed in a short time and also will not require serious investments.
Vapor tightness. This is the main property of vapor barrier membranes. The material retains all moisture from the rooms.
Excellent performance properties. The membrane withstands ultraviolet radiation remarkably well, and does not change its structure and strength. It is frost-resistant, so even at a temperature of -20 o C it retains its vapor repellency.
Long service life. A traditional roof covering lasts approximately a quarter of a century, but if you use a vapor barrier membrane, this period will increase to 40–50 years.

The disadvantages of the product include low resistance to mechanical damage. In other words, the material can be pierced, cut, etc.

The vapor barrier membrane provides a simple and inexpensive coating to protect roof insulation from becoming wet due to condensation of moist vapors escaping from living spaces.

The main argument in favor of using a “breathable” membrane is the absence of the need for a counter-lattice

Polymer roofing membrane

The polymer membrane is a new material that is used for the construction of soft roofs. It is made from sufficiently elastic high-quality polyvinyl chloride, which ensures excellent reliability, quality of roofing, consistency of technological properties, as well as a long service life.

When laying a polymer membrane in one layer, a much more durable coating is obtained than when using several layers of rolled products. All seams are sealed with hot air using special equipment, which ensures a high level of water resistance for a long time.

Among the characteristics that distinguish a polymer membrane are:

resistance to UV radiation;
good resistance to rotting and decomposition over many years;
immunity to bad weather conditions, chemically active substances and the effects of various bacteria;
ease;
possibility of use in the construction of prefabricated and mobile structures;
waterproof;
maintainability;
strength;
resistance to deformation, allowing the use of this material on roofs of various shapes and configurations.

Disadvantages of a polymer membrane:

The properties of the superdiffusion membrane resemble skin. It is able to protect not only the insulation, but also the internal parts of the building structure from external moisture, allowing the steam escaping from the under-roof space to pass out.

Similar membrane technologies are used in clothing. Down jackets and shoes prevent a person from getting wet and sweating, which means they remain warm and dry in any weather.

The product can be made from 2–4 layers of polypropylene, which gives the membrane increased strength while maintaining its ability to stretch and flexibility. The inner layer provides diffusion characteristics, and the outer layer provides wind, moisture and dust protection properties, as well as UV stabilization.

The superdiffusion membrane does not require gaps; it can be attached directly to the insulation. In addition, the material does not require a counter-lattice over the rafter system. All these properties greatly reduce the cost of insulating the building and installing the roof, allowing you to save space during the construction of the roof and walls.

The superdiffusion membrane can be laid directly on the insulation without creating a ventilation gap

The superdiffusion membrane has the following advantages:

easy to install since there is no need for special training;
protection of insulating material from dust, wind, and moisture;
reduction of heat loss;
excellent vapor permeability;
durability (service life is 25 years or more);
strength;
ease;
fire safety;
resistance to sunlight.

Disadvantages of the superdiffusion membrane:

not used with metal tiles (if they do not have an acrylic coating), as well as with Euro slate - bitumen corrugated sheets;
the pores of the material may become dirty or dusty, which reduces vapor permeability.

A superdiffusion membrane is not used if the roof is covered with metal tiles without the use of acrylic coating, seam metal material, or Euro slate. These materials can become very hot and form a lot of condensation during sudden temperature changes, which only an anti-condensation membrane can cope with.

Anti-condensation membrane

The anti-condensation membrane is a coating made of polypropylene material and waterproof coating. This combination of components contributes not only to the absorption of steam, but also to its removal beyond the boundaries of the roofing material. The membrane traps condensation that forms on the inside of the roof, protecting the supporting structure of the building. After installation, the pile retains condensate with a mass much larger than its own.

The main area of use of the anti-condensation membrane is pitched metal roofs (metal tiles). It is these coatings that need good protection from moisture. Due to violations of technology, the use of low-quality materials, as well as exposure to temperature changes, microscopic cracks may appear on the metal, which become centers of corrosion when water enters. The use of an anti-condensation membrane will eliminate such problems, since the absorbent layer of the material is able to quickly absorb not only condensation, but also steam.

The anti-condensation membrane protects against large amounts of moisture that forms on metal roofing coverings during the cold season

The anti-condensation membrane is not perforated and therefore is not a “breathable” material.

Advantages of the anti-condensation membrane:

environmental safety, since the material does not react with alkalis and acids;
absence of odor and any fumes when heated;
maintaining characteristics throughout the entire operational life;
strength and resistance to environmental influences;
the presence of a UV stabilizer that helps to operate the membrane in open sunlight;
small weight that does not overload the rafters of the house;
high speed and ease of installation;
low thermal conductivity;
affordable price.

The disadvantages of the material include the following factors:

it is necessary to install the membrane only in dry weather;
the membrane is not laid on a continuous flooring;
the product should not come into contact with the insulation;
installation must be done with several ventilated gaps.

It is necessary to select the optimal membrane based on the architectural and design features of the structure, as well as climatic conditions.

Membrane "Tefond Plus"

“Tefond Plus” is a dense cellular membrane on which special locks and insulating seams are located. They make laying the material easier. Tefond Plus products are widely used because they can provide excellent roof protection using glued and bitumen waterproofing. The membrane is not destroyed by chemicals or large accumulations of water.

In addition, the material has high strength, so there is no risk of it breaking during installation. Such a membrane can perform the function of drainage, removing water into special wells. The wear resistance and strength of the Tefond Plus film increase the service life of the roof to 50 years. By using the material on horizontal planes, you can be sure that the load on the base will be distributed evenly, which means that the roof will be reliably protected from negative influences for a long time.

When using the Tefond Plus membrane, the service life of the roof increases to 50 years

Logicroof roofing membrane

The Logicroof membrane consists of 3 layers of film. At the same time, it contains a variety of stabilizing components and expensive high-class additives that minimize the threat of fire, which is confirmed by certificates and multiple tests of the material for fire safety. And thanks to the use of modern and unique technology, the surface of the material is covered with a layer containing an increased concentration of substances that protect against ultraviolet rays. The result is excellent resistance of the membrane to sunlight and a significant increase in service life.

All types of Logicroof membranes have common advantages:

UV protection;
high elasticity;
reliability;
resistance to climate influences;
resistance to various chemical and biological substances;
ease;
fire resistance;
excellent tensile strength.
