Windproof membrane is a fairly new material on the construction market. Its demand began to grow with the peak of popularity of the construction of frame houses. But besides this, such a membrane material is very important not only when insulating the walls of a house, but also when arranging the roof, where it has become an integral layer of the “pie”. This stage during construction work should be provided for at the design stage or at the very beginning of repairs. This article will discuss how to choose a windproof membrane for your home and install it correctly.
Tip: a windproof single-layer or double-layer membrane is used only on the outside on top of the insulation, and a vapor barrier membrane is used on the inside of the house, as a finishing layer before installing drywall.
Today there is a very wide variety of windproof membranes on sale, both foreign and domestic. They all vary greatly in price and features. According to their technical characteristics, windproof membranes for the home can be divided into:
Depending on what goals they want to achieve, windproof film is attached to the walls of houses, roofs or ceilings of attic floors.
This brand occupies one of the leading positions in the windproof membrane market. It has been known for more than 25 years, during which it has proven the high quality of its products. The hydro-windproof film is sold under the name “Ondutis” and, depending on the purpose and properties, is available in several names:
This is an excellent combination of price and quality, so you can buy it at any hardware store. The isospan windproof membrane is quite versatile and suitable for use in insulated roofs covered with any roofing material: metal, natural tiles or bitumen tiles.
In addition to the most famous and popular models, there are products with increased fire-resistant qualities on sale. Special fire retardants in the fabric itself help achieve this; this can protect the structure from fire, both during construction work and during operation. Although its price is higher, in some cases fire requirements allow the use of only such a membrane.
Wind protection isospan was constantly improved, which made it possible to achieve a number of advantages over other analogues:
Depending on the specific construction goals, you can also choose the most appropriate option from the line presented by the manufacturer:
These are vapor-permeable, wind- and moisture-proof materials that are available in different brands. The choice depends on the specific conditions and goals to be achieved. They are all sold in standard rolls of 70 m2.
All membrane materials for house construction can be divided into several main categories. So, depending on the structure of the material and its purpose, there are vapor-permeable and vapor barrier films.
Vapor barrier membrane
Tip: the presence of a vapor barrier on the wall and roof structures of the house creates a “thermos” effect. This is good for saving energy when heating, but it also greatly increases the humidity in the room. Therefore, supply and exhaust ventilation systems must be installed in them.
Vapor-permeable windproof membranes for walls and roofs

Wind protection for a frame house is a mandatory element that is used in this type of house construction. Such a layer can protect the entire house from blowing. It is worth noting that if this layer is neglected, then during strong winds the walls will let in cold from the outside and give off their heat from the inside. And this will lead to high costs for heating the room.
The wind protection layer has the following functions:
Various materials can be used to create a windproof layer
Most often, when constructing frame buildings, special films called membranes are used to provide wind protection. Such materials do not let in cold and wind from the street, but at the same time freely release excess moisture from the insulation. Most often, such material is sold in the form of rolls about one and a half meters wide.
Such films can be installed not only during the construction process, but also during renovation work.
The main advantages of this material are:
When choosing a windproof film, you should pay attention to its vapor permeability properties. It is better to give preference to species with high rates.
Isoplat slabs can be used as wind protection. Such materials will not only provide protection from the wind, but also provide additional heat and waterproofing. Due to their plasticity and density, they are securely attached to the structure of the house, thereby providing reliable protection from wind, cold and moisture.
This option can also be used as a windbreak, but there is one point to consider. They have low vapor permeability. For this reason, when using them, it is worth installing high-quality vapor barrier indoors.
This material is ideal for wind protection at home. At the same time, he will level the walls. Facade plasterboard is an environmentally friendly material, because it is made from natural ingredients.
The advantages of façade type plasterboard are:
For wind protection of houses, you can use other materials, for example, fiberboard or EPS boards. Each of the materials has its own advantages and features.
A frame wall most often has the following layers:
The process of installing a windproof layer will be considered using a film windproof membrane.
First, thermal insulation of the walls is required. Most often, mineral wool is used for such purposes. Its installation must be done carefully, without the formation of voids or protrusions. The windproof membrane itself is attached to the insulation. The material should be fastened with the drawings facing up (most often, the specifics of the installation process are indicated by the manufacturer in the instructions).
Thanks to excellent transmission properties. The vapor membrane can be mounted tightly to the insulation layer using a construction stapler.
The film is laid horizontally. In this case, it is necessary to make an overlap, the width of which is indicated on the film by the manufacturer. Many manufacturers equip their membranes with an adhesive layer for better sealing. But if there is no such layer, then you can connect the layers using double-sided tape.
Then the membrane is secured with a counter-batten, which is pre-treated with an antiseptic.
After installing the slats, the wind barrier layer is considered complete and the outer walls are ready for finishing.

A moisture and windproof membrane is a fireproof construction fabric that protects insulation from moisture and heat loss during air movement.
In general, windproof film is used in various areas of construction: in roofs, ceilings, partitions, floors, and in finishing bath walls. But we, as professionals in the field of facade construction, are only interested in membranes laid on insulation in ventilated facades, frame walls, and in any wall cladding with external insulation, but without a ventilation gap.
Moisture and windproof films protect the surface of the insulation from water and moisture, from mechanical damage, and also prevent heat loss due to longitudinal filtration of air in the insulation. Protection is especially important during slanting rain, then the insulation is abundantly wetted and, if there is no ventilated gap that quickly dries the surface, there is a risk of freezing of the walls. Wet insulation loses up to 90% of the energy saving characteristics declared by the manufacturer. The vapor barrier film must be laid with the smooth side facing out.
The windproof membrane for cladding the facades of expert buildings must correspond to the group of non-combustible materials - NG. All manufacturers declare compliance with the NG group. Has anyone tried to set fire to a piece of vapor barrier film with a lighter? Those involved in the construction of facades have probably tried everything. The film burns out, the flame dies out, it does not support combustion, but there is a certain emotional moment in the subjective assessment. Porcelain tiles, metal bracket - NG, which is logical. Set fire/don’t set fire, at most the element will become smoky. But the membrane behaves differently, it burns down to the base, but fades out. It turns out that the film itself does not burn, but with an external source of fire, the flame will spread across it. However, there are permits issued by competent and authoritative authorities.
The permitting documents for windproof membranes used in facades are:
Based on an analysis of the permitting documentation from a number of manufacturers, it is possible to come to conclusions regarding the typical properties and characteristics of windproof membranes.
The requirements for windproof membranes used in private and public buildings are different. At a minimum, because public buildings are subject to state construction expertise. The scale of the consequences of using low-quality film when cladding high-rise buildings is more extensive. By not very high-quality film, the editors first of all understand that it does not comply with the flammability group NG is a non-flammable material.
Let's consider the most common way of using windproof membranes in facades
The fabric is supplied in rolls, 1.2 m wide and 50 m long. Designed for installing a wind-hybrid barrier layer in enclosing structures, incl. in the designs of facade systems with an air gap, to increase their resistance to air permeation and protect the insulation from adverse atmospheric influences. The membrane can be used in all climatic regions, at temperatures from -60 to +60 degrees, in mildly and moderately aggressive environments.
The precedent of not using a windproof membrane was created by the manufacturer of a well-known brand of Chelyabinsk insulation. They received a new Technical Certificate for their own products, which contains a clause allowing the use of insulation with a cached layer without the use of a wind-hydroprotective membrane. The development contributed to the promotion of products to the market. This insulation itself is quite expensive, but when installing the “pie” of the facade system, the contractor saves due to the absence of a membrane. This idea was picked up by other insulation manufacturers, and away we go.
This state of affairs fundamentally does not suit membrane manufacturers, which is logical. Manufacturers conduct extensive educational activities aimed at disseminating information about the consequences of abandoning the hydro-wind barrier layer.
The insulation is destroyed under the influence of high pressure and gusts of wind in the ventilated gap of the system.
Water and moisture get on the insulation, and in winter, without having time to dry, it turns into ice. By the way, there is a separate article about installing a façade in winter. This reduces the thermal protection properties.
In places where moisture penetrates strongly, the insulation may become overgrown with moss.
Many people believe that windproof film burns. The spread of thrust in the gap from bottom to top contributes to the spread of the flame. Therefore, a horizontal fire cutoff is used on each floor. Which is also wrong, because... the principle of a ventilated facade is violated.
The rest of the arguments boil down to refuting the positions of defenders of the use of the system. They say that the insulation is not destroyed by the wind, because... it has a cached layer that is denser in relation to the underlying density of the mineral slab. And getting wet mineral wool in ventilated facades is not a problem, because... The wind flow in the air gap is such that it dries the water almost instantly.
The editors will leave their opinion on the need to use a windproof membrane with you, so as not to be torn apart by the warring parties.
But the truth, as always, is somewhere in the middle.

The peculiarity of this material is is that it has good thermal insulation characteristics, which make it possible to provide a high level of protection of any buildings from such negative factors as wind and moisture.
The windproof membrane eliminates the possibility of high humidity in attics. This is ensured due to the presence of high heat-reflecting properties in the Izospan material, which provide protection against condensation. When installing a vapor-permeable membrane, connecting tapes are used, which ensures high tightness of the fastening. In addition, the material provides a high degree of wind protection for the building.
Currently, windproof membranes are widely used. It is used when carrying out internal and external works on thermal insulation of floors and walls. A windproof membrane is also used when solving problems of insulating floors. The use of this material protects structures from condensation and prevents damage to the finish.
When working on flooring, the Izospan windproof membrane is often used as a floor substrate. The use of this material for this purpose provides good reflection of infrared rays, which direct the heat flow directly into the room. In addition, good wind protection is provided.
When using a moisture-proof membrane Izospan provides reliable protection against:
Thanks to the functional aspects that are characteristic of the Izospan windproof membrane, it is possible to significantly reduce the temperature load affecting any building under conditions of temperature changes. Using a windproof membrane as a moisture-proof material provides protection:
The use of vapor-permeable material allows you to create favorable conditions for living in a house that has high-quality insulation. Note that windproof material is used to make special suits, which keep the person wearing such clothing dry in rainy weather and are well protected from the wind.
A membrane from well-known manufacturers that provides reliable wind protection, which is available in a large assortment on the market, characterized by:
When using the windproof membrane for walls Izospan, its installation is carried out directly on insulated and ventilated facades. It is also used in the construction of houses built using frame technology. Unlike the roof here no horizontal sections where moisture could accumulate. For this reason, the requirements for the windproof material used are somewhat different.
If a conventional façade is facing and insulated, then in this case you can use absolutely any windproof material that has good permeability. The main purpose of using a windproof membrane is to prevent the penetration of moisture and prevent the accumulation of condensation in the insulation layer.
High-quality wind protection is especially necessary in ventilated facade systems. When installing them, it is an impossible task to ensure that the cladding elements are tightly connected to each other. For this reason, wind and moisture can penetrate through the joints into the ventilated façade. Strong wind currents may arise behind the cladding of a ventilated façade, which can destroy the unprotected insulation with their force.
Mineral wool is especially susceptible to this negative factor. The use of a windproof membrane ensures the fixation of the heat insulator and its reliable protection from destruction. As a result, the insulation structure is preserved in its original state and the microclimate in the premises of the building does not undergo major changes.
In all houses that are built of wood, a windproof membrane is installed on the floor. These buildings differ from buildings that have concrete floors in that they are able to allow wind to pass through the floor. For wind protection of wooden floors, the choice is usually made in favor of options based on polyethylene or propylene. This is due to the fact that the windproof membrane has good waterproofing properties. Good properties in terms of moisture protection are also characteristic of a suit made of membrane fabric.
When installing the floor, it is necessary to lay waterproofing and a layer of insulation on the joists, and then wind protection. When these operations are completed, you can begin laying the finished floor. If the installation of the windproof membrane was carried out correctly, then a favorable microclimate arises when living in the house, while the installed insulation does not lose its performance characteristics for a long time. When installing wind and water protection, preference should be given to the material that is most suitable for each area of the house.
When building a house, many people take the choice of materials for building a house, insulating structures and insulating insulation very seriously. When choosing a windproof membrane, you need to pay attention to specifications, and do not forget about such a moment as price. Having data on the cost of a windproof membrane, you can make the right choice and calculate in advance the cost of insulation work. When choosing a suit made of membrane fabric, which perfectly protects against moisture, the cost of the product is also an important point.
When choosing a windproof material, you need to familiarize yourself with the assortment of several stores, and then decide on the place where the membrane with optimal technical characteristics is offered. You should do the same thing when you are looking for a suit made of membrane fabric. This approach makes it possible to avoid unnecessary expenses and get a product with high quality characteristics.
If we talk about the current market situation, the price for high-quality windproof material varies in the range from 1500 to 3000 rubles per roll. A suit made of membrane fabric will cost less. Of course, the price of a protective membrane may vary depending on the manufacturer, as well as its density and the material from which it is made. Products made from polyethylene and polypropylene are widely represented on the Russian market.
Each private developer, when constructing a house, naturally insulates it so that living in his own home is as comfortable as possible. To ensure that the thermal insulation layer retains its performance characteristics for a long period, the insulation is insulated using a windproof membrane. You can purchase it without any problems, since the market offers a large selection of products from various manufacturers.
Many people choose a windproof membrane from the Izospan company. She has proven herself to be manufacturer of quality materials, with which you can provide reliable protection from wind and moisture. This manufacturer produces a membrane that can be used to insulate walls and floors. By choosing the right material with the required characteristics, and then performing competent work on its installation, you can get a comfortable home that will always be warm.
Nanoizol A is a modern wind- and moisture-proof material that is used in the construction and reconstruction of walls and roofs of buildings for any purpose. It is a membrane with sides of different textures: the inner side is rough, and the outer side is smooth. The rough surface retains drops of condensation until they evaporate and thereby protects the insulation and other materials from being moistened by vapors coming from the premises. The outer (smooth) surface has water-repellent properties and prevents the penetration of moisture from the external environment into other structural elements. The Nanoizol A membrane is installed on the outside of the insulation, under the roofing or the external finishing material of the wall. Its use improves the thermal insulation properties of the insulation and helps extend the life of the building as a whole.
The vapor-permeable wind-moisture-proof membrane Nanoizol A is made from modern polymers. This material has a number of advantages compared to traditional analogues:
Nanoizol A can be used as a wind- and moisture-proof material in the construction of insulated roofs with a slope of 35° or more. The membrane is suitable for roofs with any covering: soft roofing, corrugated sheets, etc. Installation is carried out on top of the rafters above the insulation, with a ventilation gap. A sheathing is installed on top of the membrane. In insulated roofs, Nanoizol A serves to protect the thermal insulation material and load-bearing elements from wind, dirt, dust, moisture from under-roof condensation and moisture from the external environment.
In the construction of low-rise buildings, the Nanoizol A membrane is used in the construction of walls with external insulation: timber, frame, panel, and combined. It serves to protect materials from wind and moisture. It is used for external insulation of walls with any external cladding: lining, clapboard, etc. Installation is carried out on the outside of the insulation, under the external finishing material of the wall.
Nanoizol A is used to protect insulation in the structures of ventilated facades of buildings with external insulation. Protecting the insulation from the effects of cold air, wind, moisture and snow penetrating into the ventilated gap under the outer cladding.
When laying Nanoizol A on the roof, roll it out horizontally over the insulation and rafters, with the smooth side of the material facing outward. The membrane is cut directly onto the roof. The canvases are laid from bottom to top, overlapping. The width of the overlaps at horizontal joints should be at least 15 cm, at vertical joints - 20 cm. A ventilation gap of 7-8 cm wide should be left near the ridge between the panels. The membrane is secured with wooden counter-battens to the rafters; self-tapping screws or nails are used as fasteners. A continuous flooring or sheathing is mounted on the counter-battens (depending on the roofing used). To ensure the evaporation of condensate, a ventilation gap of 2-4 cm wide is left between the membrane and the heat-insulating material. A ventilation gap equal to the thickness of the sheathing is also provided between the roofing and the membrane.
Euromet specialists recommend securing the membrane in a tensioned position. It should not sag between the rafters by more than 2 cm and come into contact with insulation or other surfaces. This can lead to a deterioration in its waterproofing properties. Nanoizol A is placed so that moisture flows freely from the surface of the membrane along the lower edge into the gutter. To ensure the evaporation of condensate and weathering of water vapor, the under-roof space is made ventilated. Air circulation is carried out through ventilation holes in the ridge area and at the bottom of the roof.
The Euromet company would like to remind you that Nanoizol A is not intended for use as a roofing covering. For temporary covering of building structures, the Nanoizol D membrane can be used.
In the construction of walls with external insulation, Nanoizol A is mounted between the insulation and the outer cladding of the wall. The membrane is laid on the outside of the insulation on a wooden frame, with the smooth surface facing out. The canvases are placed horizontally, at the joints they must overlap each other by at least 10-15 cm. The material is fixed to the frame with galvanized nails or using a construction stapler. Wooden counter-battens are fixed on top of the membrane, which ensure the creation of a 4-5 cm wide ventilation gap between it and the outer cladding of the wall. External finishing material (siding, lining, etc.) is then attached to the counter-battens. Water should flow freely along the lower edge of the membrane into the drain.

Building a house is a responsible process, so every developer makes sure that construction technology is not violated. After all, the durability of the future home and its comfort depend on this.
Currently, many materials have appeared for the outer cladding of a house, making it possible to protect the main supporting structures from adverse atmospheric influences. Their appearance made it possible to insulate houses from the outside using slab or roll insulating materials based on mineral wool.
But, as you know, the worst enemy of any insulation is moisture penetrating into it, which significantly reduces the thermal insulation characteristics of the material. Therefore, the insulation needs to be protected, not only from possible atmospheric influences, but also from moisture penetrating from inside the house. For these needs, special roll materials are used - vapor and wind insulation.
The vapor barrier is mounted directly on the wall of the building, prior to the installation of thermal insulation. And the wind protection should be tightly adjacent to the surface of the insulation from the outside.
Wind protection is used when it is planned to install a ventilated façade using external insulation.
Do not think that only new buildings are insulated in this way. This option can also be used to insulate an old building if necessary.
Moreover, this method is successfully used for insulating not only frame and wooden houses - it is suitable for concrete and brick walls.
Windproof films are also used to protect floors, ceilings, and roofs. The only condition is to use them only on the “cold” side: directly under the roofing, subfloor or on the street side of the external walls.
The main condition for the functionality of wind protection is its correct installation. The technology itself is simple.
It would seem that using wind protection only has a positive effect. But its use has disadvantages that you also need to be aware of.
But there are also disadvantages, which mainly arise due to improper execution of work and errors in the design of a ventilated facade.
Despite criticism of windproof films and membranes, they are in demand among the population and the construction industry. Therefore, manufacturers tried to eliminate the shortcomings and released materials with new properties to the market.
Nowadays there are quite a lot of windproof materials on sale with low flammability and even completely non-flammable: non-flammable windproof membrane DELTA®-FAS NG; “Izospan AF”, “Izospan AF+” and others.
So if you want to improve the fire safety of your home, it is worth spending money on more expensive, but also more reliable materials.
A completely new product was Izoplat slabs, which are sheets of heat-insulating material with wind protection, sound insulation and insulation properties. They are made from softwood fibers without the use of any adhesive, so they are absolutely harmless.
Plates differ favorably from films in that they have stable geometric dimensions that do not change over time. Therefore, once correctly installed, they will serve for a long time: cold bridges do not form between them, they cannot be torn by the wind or destroyed by the touch of a sharp object. In this case, a slab with a thickness of 25 mm in terms of thermal insulation corresponds to a wooden wall with a thickness of 90 mm. The material is perfect for use in cold and humid climates.
When planning the construction of a frame house, where the comfort of living in it depends entirely on the insulation, it is worth making sure that it is reliably protected from any adverse influences that destroy its structure and reduce its thermal protection characteristics. Therefore, for wind protection, it is better to choose high-quality materials that are guaranteed to be worth the money spent.
