TechnoNIKOL three-layer vapor barrier reinforced vapor barrier film. Vapor barrier film: types and technical characteristics TechnoNIKOL reinforced

Roof insulation is one of the most important aspects of building a house; for this you have to purchase expensive insulation materials, the service life of which depends on proper use and operation in any, even the most unfavorable climatic conditions.

To reliably protect the insulation layer on the roof from the effects of moisture penetration, you cannot do without such a component as a vapor barrier film. TechnoNIKOL vapor barrier has excellent moisture resistance, thanks to which it well protects thermal insulation materials from the penetration of condensate.

Vapor barrier film Designed to protect insulation material from moisture. TechnoNIKOL, consisting of a three-layer structure, is used to completely protect the insulation from the formation of moisture in it. The technical characteristics of the TechnoNIKOL vapor barrier film meet all regulations, so it can be laid on any surface without fear.

Types of TechnoNIKOL film

The vapor barrier material of this company is divided into two types:

1. Diffusion membrane (two-layer). It consists of non-woven fabric and polypropylene, which are applied to a polymer base. This structure creates a vapor barrier that reliably protects against moisture from the outside. This type has good strength, which allows it to withstand heavy loads. The diffusion membrane is often used for vapor barrier of pitched roofs, insulation of floors between floors and walls.
2. Perforated vapor barrier film. It is made of polyethylene and also has high strength, so it copes well with huge volumes of moisture. It has a large number of holes in its structure through which moisture is actively removed to the outside. This type vapor barriers are used for waterproofing flat roofs and walls from the inside.
3. Universal film. Consists of two layers of polypropylene with polymer coating. Its structure allows this type of film to be used for vapor barrier of pitched and flat roofs. The universal film is used as an under-roof insulation material that protects the insulation from wind and moisture.
4. Reinforced vapor barrier (combination of non-perforated and perforated). This material is even more durable thanks to several layers of reinforced film with small holes. Having such characteristics, it reliably protects the living space from moisture, removing condensation from the layers of thermal insulation, thereby contributing to the formation of an impeccable microclimate in the house.

Features of vapor barrier film

The main advantages of the product produced by TechnoNIKOL include the following indicators:

1. Environmental friendliness of the material. During operation, it does not release toxins.
2. Versatility. Due to its properties, the film can be used to protect roofs, walls, swimming pools, ceilings, etc.
3. Affordable price with good quality material.
4. Prevention of mold and mildew formation.
5. Easy installation of vapor barrier.

Installation of TechnoNIKOL vapor barrier is carried out with the smooth side facing towards the room. The reinforced film can be laid with either side facing the insulation. Horizontal and vertical strips are attached to each other using a stapler or double-sided construction tape; first, for the joints, you need to leave 20 cm in reserve to make the joint overlap.

Price of vapor barrier film from TechnoNIKOL

The cost of vapor barrier may vary in some regions, but average looks like that:

nyaya – 950 rub. per roll;

• for a flat roof – 1,330 rubles;
• for pitched – 2,130 rubles;
• reinforced vapor barrier - 1,360 rubles.

The technical and operational characteristics of the TechnoNIKOL vapor barrier film guarantee protection of the insulating material from steam coming from the interior of the room, preventing the formation of condensation and a comfortable humidity level in the room. TechnoNIKOL film can be laid directly on the base of the structure. The main characteristics of the vapor barrier film are as follows:

• length – 100 meters;
• width – 3 m;
• thickness – 0.12 mm;
• elongation at break – 260%;
• vapor permeability – 1.11 g;

TechnoNIKOL vapor barrier film, used for flat roofs, is resistant to ultraviolet rays for 1.5 months.

Vapor barrier film TechnoNIKOL: types and specifications

Vapor barrier films - choosing a quality material

Vapor barrier is widely used in wooden house construction. Any vapor barrier films are attached to wooden structures in front of the insulating layer. For fixation, staples and a special stapler are most often used. Laying is done using butt or overlap methods, and for gluing seam joints they are used adhesive tapes. Today there are several types of such films.

Types of vapor barrier films

The main requirement for vapor barrier films is the ability to transmit minimal steam, as well as maintain maximum strength during installation with no deformation changes.

Thermal reflective or foil film

This category of vapor barrier films not only protects against the accumulation of steam, but is also an excellent barrier that protects against thermal radiation. Standard heat-reflecting films are characterized by a combination of several functions at once and allow you to protect the structure from steam, having the highest quality thermal insulation properties and guaranteed to reflect heat into the room being equipped.

The use of material from the “three in one” category helps to significantly simplify all work installation work and reduces the cost of consumables.

Standard types of polyethylene films used for vapor barriers. They are produced with reinforcement with special reinforcing meshes or fabrics, giving guaranteed strength.

They have certain advantages compared to polyethylene analogues, the main of which are higher strength and resistance to ultraviolet radiation. Polypropylene is capable of protecting structures from atmospheric precipitation for about twelve months while awaiting the installation of roofing materials.

To minimize the formation of condensation, one side of the reinforced polypropylene film is equipped with a special anti-condensation layer consisting of viscose fiber and cellulose. The main purpose of such a special layer is the ability to perform moisture-absorbing and moisture-retaining functions, followed by very quick drying under the influence of air flow.

Anti-condensation polypropylene films are placed with the main layer facing down, but creating a ventilation gap remains relevant. Moderate cost and good strength indicators make this type of film very popular.

Manufacturers and technical characteristics of the material

Modern vapor barrier films on construction market Russia is represented by several manufacturers that produce fairly high-quality products.

Vapor barrier for flat roofing Techno NIKOL (3x30 m). - multilayer polyethylene film

Vapor barrier films provide moisture resistance long years and are divided into diffusion and non-perforated.

Diffusion "breathing" membranes are the best option for under-roof insulation materials, consisting of a continuous polymer film with two layers of polypropylene fabric.

Non-perforated type of films designed to protect any space not only from moisture, but also from dust deposits. During the production process, reinforcement is used using a special mesh or fabric, which gives additional strength. Most often used for vapor barrier work during roof installation.

Roll materials are easy to install and connect.

In addition to a wide range, the manufacturer guarantees a reliable thermal insulation barrier and protection against wetting and weathering. Main options:

• vapor-permeable membranes are durable, dense and UV-resistant;

• propylene two-layer membranes;

• propylene laminated with film.

• Izospan-V film - vapor protection for pitched roofs or attic floors;

• Izospan-D film - laminated propylene for non-insulated roof types;

• Izospan-DM film - propylene with one-sided anti-condensation coating, resistant to any mechanical stress.

Yutafol vapor barrier films are used as thermal insulation and hydro-protection.

The brands N, SP1, NAL Special and D are produced.

The main application is the installation of a vapor barrier in conditions of ventilated inclined roofs, as well as when arranging the roof with soft tiles. When performing seam sealing of this roll material applies special type construction tape.

How to choose the best

The choice of vapor barrier is based on an assessment of the functional properties of the material. The diffusion type of membranes is one of the universal modern materials that can be used in any type of roofing structure and in combination with all methods of insulation. This vapor barrier is several times more expensive than other types of waterproofing films.

The installation of waterproofing on non-insulated roofs allows the use of ordinary universal or perforated film from proven and well-established manufacturers.

When arranging pitched metal roofs It is advisable to use anti-condensation films.

Material cost

The most significant criterion for choosing a film for vapor barrier is price.

The cost of TechnoNIKOL films starts from 3,000 rubles per roll. Vapor barrier films from TechnoNikol for the installation of pitched roofs cost about 1,150 rubles per roll, and the price of reinforced materials averages 1,875 rubles per roll. Materials for vapor barrier of flat roofs - from 1697 rubles per roll.

Vapor barrier Izospan has a competitive price. The cost depends entirely on the brand vapor barrier material. The price of Izospan-B is several times lower than the cost of heat-reflecting Izospan-FX. High price thermal insulation from this manufacturer is due to its stable durability and excellent performance characteristics.

The best option is to use vapor barrier films from Yutafol, the cost of which starts from 1,500 rubles per roll.

• any waterproofing film mounted above a layer of thermal insulation;

• The roll of material is rolled out perpendicularly rafter system in the direction from bottom to top;

• the standard overlap is from fifteen to twenty centimeters;

• To seal the joints, special tape or connecting tape is used.

Types of vapor barrier film - how to choose the best one and its technical characteristics

Technical characteristics and methods of installing TechnoNIKOL vapor barrier in insulation systems

The Technonikol company is a leading manufacturer of roofing, vapor and waterproofing materials in Russia and the CIS. Factories producing vapor barriers for polymer based, located in Russia, Belarus, Lithuania, Ukraine and the Czech Republic. TechnoNIKOL vapor barrier meets European requirements, quality and safety standards, which makes it possible to successfully use it for low-rise residential and industrial construction of houses with various systems insulation.

Purpose and types of TechnoNIKOL vapor barrier films

Vapor barrier materials are designed to protect insulation from condensation that forms inside the room. The installation of a roof and wall insulation system is not allowed without the use of a vapor barrier in accordance with SNiP 23-01. Roof vapor barrier prevents the formation of condensation on the materials that make up the roofing “pie”, ensuring the preservation optimal microclimate in the house for a long time. Using a vapor barrier prevents the appearance of mold, mildew, and unpleasant odors.

The vapor barrier layer is laid immediately before installation of the thermal insulation material. The choice of vapor barrier material depends on the temperature and humidity conditions in the room, the climate of the region, financial capabilities, roofing and wall materials. Technonikol vapor barrier film is made from high-quality polymers and has a multi-layer structure, thanks to which optimal vapor permeability and high strength are achieved.

Important! Before installing the film, carefully study the “Roof Installation and Design Guide” issued by the manufacturer. Follow the instructions strictly and do not use the material for other purposes.

The Technonikol company produces several types of vapor barrier:

• for pitched roofs, with the ability to partially transmit steam;
• for flat roofs, having high strength and elasticity;
• reinforced, reinforced three-layer film high strength;
• universal, suitable for all types of roofs.

Vapor barrier OPTIMA

The peculiarity of this material is excellent vapor permeability and at the same time a high vapor barrier. This is possible thanks to a three-layer membrane, in which the top and bottom layers are made of non-woven polypropylene, and the middle one is a vapor-permeable film. The combination of OPTIMA material with fiber insulation ensures the temperature and humidity in the room as close as possible to that of a log house, creating comfortable conditions for year-round use.

Technical characteristics of OPTIMA vapor barrier:

• tensile load along the length and width – 160 and 120 N/5 cm;
• vapor permeability – 5 Gy/(m/day);
• thickness – 0.3;
• water resistance – >2 m water. pillar;
• operation at temperatures from -40 to +85 degrees;
• high resistance to UV rays.

OPTIMA is universal material and is used for installing a vapor barrier layer in insulated attics, sloping roofs without insulation, ceilings, external walls with a multilayer structure (ventilated facade), as well as for walls with internal insulation of any type. Steam penetrates through the bottom layer and is retained in the vapor-permeable layer. Some of the steam passes through upper layer and insulation in environment, ensuring the “breathing” properties of the roof. The material is easy to use and is available in rolls 1.5 m wide. OPTIMA is a TechnoNIKOL film whose vapor barrier and strength properties allow it to be used as wind protection in areas with unstable climates.

Vapor barrier for flat roofs

TechnoNIKOL vapor barrier for flat roofing is a three-layer polymer material, all layers of which are made of polyethylene. The film has a double effect:

1. Protects the roof from water penetration from the outside, i.e. from precipitation.
2. Provides protection for flat roof elements from steam generated indoors.

TechnoNIKOL is laid on concrete surfaces under the insulation or on a corrugated sheet, mounted before laying the thermal insulation. Compared to OPTIMA, this material has greater tensile strength and higher vapor permeability rates with a smaller thickness.

Important! Using a vapor barrier that is not intended for this purpose on flat roofs will not provide the required protection from precipitation and will lead to the destruction of the roof structure.

Technical characteristics of TechnoNIKOL vapor barrier for flat roofs:

• tensile load along the length and width 160 and 170 N/5 cm;
• thickness – 0.12;
• water resistance – >1 m water. pillar;
• average resistance to UV rays.

A three-layer membrane for flat roofs can be used in private low-rise construction, in the construction of high-rise buildings, and buildings made of quickly erected structures.

Reinforced vapor barrier

Technonikol reinforced vapor barrier film, the technical characteristics of which significantly exceed conventional films for pitched and flat roofs, consists of three layers. The main layer is a reinforcing mesh made of durable polyethylene strips. This reinforced layer Covered with laminated polyethylene on both sides. Reinforcement provides the material increased stability, and lamination – high vapor permeability.

• tensile load along the length and width is 250 and 160 N/5 cm;
• vapor permeability – 1.1 Gy/(m/day);
• use at temperatures from -40 to +70 degrees

The material is produced in the form of dense rolls of 1.5x50 m. Reinforced film is strong, durable, and not susceptible to mold, rot, or corrosion. Designed for installing a vapor barrier layer for attics, mansards, sloping and flat roofs. Due to its high strength and heat-resistant characteristics, the membrane can be used in external insulation systems. The reinforcing mesh made of polyethylene helps retain heat, acting as an additional heat insulator, and layers of polyethylene retain condensation, preventing it from penetrating inside the insulation.

Important! When calculating the roof load, it is necessary to take into account that specific gravity reinforced film significantly exceeds the weight of conventional three-layer films. In some cases, to reduce the load on the roof, reinforced vapor barrier should be abandoned.

Reinforced film can be used with all types of insulation: fiber, foam and polystyrene foam. The manufacturer recommends combining it with insulation own production based on polystyrene, produced under the Technoplex brand.

A type of reinforced vapor barrier is windproof film Svitap 110 D, designed to protect surfaces from dust and moisture. This material is used in industrial construction and for the construction of low- and high-rise buildings in special climatic zones. Windproof reinforced vapor barrier can only be used for ventilated flat, pitched roofs or as waterproofing material when installing ventilated facades.

Advantages and disadvantages of materials

The advantages include:

• high tensile and tensile strength;
• does not rot, prevents the formation of mold and mildew;
• high rates of vapor permeability and water resistance;
• fire safety, the film does not support combustion;
• possibility of use in the Russian climate;
• compliance with the standards of the Russian Federation and the Customs Union;
• affordable prices.

The disadvantage of TechnoNIKOL polymer insulation is considered to be the low resistance to sunlight of most types of films. The rolled material should be covered as quickly as possible with the next layer of roofing or insulating “pie” in order to be minimally exposed to UV rays.

The affordable cost of TechnoNIKOL is the reason for its popularity among private developers and construction companies. Prices for various types of film from the manufacturer are presented in the table below. Depending on the region and specific supplier, prices may vary.

Installation of vapor barrier TechnoNIKOL

Vapor barrier can be installed in three options:

1. When installing internal insulation walls or roof, on the inside of the insulation under the finishing of the room.
2. As a vapor barrier layer in uninsulated attics.
3. During installation external system insulation of walls, residential attics, ceilings.

In each case, installation will have its own characteristics, which we will discuss in more detail.

Vapor barrier in the internal insulation system

In this case, TechnoNIKOL is located on the inside of the insulation in the form of vertical or horizontal stripes. Fastening is carried out directly to the insulation or to a wooden slatted frame using a construction stapler with medium-sized staples, as well as using dowel-nails made of galvanized sheet metal with a wide “mushroom” hat. The strips of material are hermetically glued together with mounting tape.

The outer strips must be inserted 20-30 cm behind the insulated surface and thoroughly sealed. Wooden or metal slats are installed on top if the room will be finished with siding, plasterboard, or cork panels.

Important! A ventilation gap of at least 3 cm must be provided between the interior finishing and the vapor barrier layer.

All joints must be sealed, otherwise the vapor barrier will not perform its function: condensation will penetrate into the insulation layer, it will lose its thermal insulation properties and the walls will become damp.

Vapor barrier in non-insulated roofs

TechnoNIKOL vapor barrier film is rolled out on the rafters and secured using dowel-nails or construction staples. Strips of material are laid overlapping, starting from the eaves to the ridge of the roof. The overlap of the strips horizontally should be at least 15 cm, and vertically - 20 cm, while the vertical joints should be located on the rafters.

Important! The formation of joints, creases, and sagging on the film is unacceptable, because this promotes moisture accumulation.

Accumulated moisture must be removed along the lower edges of the film into drainage gutters. A frame of wooden slats is laid on top of the vapor barrier layer, followed by the final finishing.

Vapor barrier in external insulation system

TechnoNIKOL reinforced vapor barrier, the technical characteristics of which allow it to be used in external insulation, can be mounted horizontally or vertically on top of the heat-insulating material. Fastening is carried out with staples or dowel-nails. Reinforced film can be attached on either side. The joints must be securely sealed with tape or mounting tape. Joints adjacent to the structure must be additionally sealed using foam or sealant for external use.

When installing a ventilated facade and other types of insulation using TechnoNIKOL films, it is necessary to constantly monitor the integrity of the material, preventing it from breaking.

• Foil reflective vapor-tight armor.

Vapor barrier film Yutafol N 96 Silver

The film Yutafol N 96 Silver is endowed with all the properties of a classic vapor barrier. Consists of two layers of polypropylene. The manufacturer uses the letter “H” to designate all of its materials that serve to create protection against steam; the number in the abbreviation indicates the density of the material. So Yutafol N, wound into a roll, has dimensions of 1.5 x 50 meters and a density of 96 grams per square meter. Ultraviolet stability is ensured throughout 3 months, Thus, vapor barrier requires mandatory shelter from the sun. Refers to highly flammable group B3.

• Installation must be carried out at ambient temperatures above +5 °C.

The main application of Yutafol N 96 Silver is in the arrangement of pitched and flat roofs; it is spread on the inside of the room in front of a layer of thermal insulation material. The material is also used in internal wall partitions. The joints of the film must be hermetically sealed with JUTAFOL tape. You can often hear the question about which side to lay the Yutafol vapor barrier? In fact, the Yutafol film can be laid on absolutely any side, since both sides have the same protective coating - polyethylene film.

Vapor barrier film Yutafol N 110 Special

Film Yutafol N 110 Special contains three layers:

Top and bottom layer of polyethylene film;

In the middle there is a reinforcing mesh made of polyethylene strips;

Reinforcement increases strength characteristics, and double-sided lamination with polyethylene creates a powerful vapor barrier, ensuring complete impermeability. The film Yutafol N 110 Special, unlike Silver, contains in its composition a special reagent that promotes self-extinguishing upon ignition. Because of the reagent, the film received flammability class B1 and is classified as a low-flammable product. On the surface of the vapor barrier Yutafol N 110 Special, with an indentation from the edge of 12 cm, a black stripe is applied, indicating the recommended amount of overlap on next layer when laying.

The three-layer vapor barrier JUTAFOL N 110 SPECIAL is a 110 g/m² vapor barrier that is designed to create highly efficient vapor barrier layers on inside thermal insulation. The vapor barrier promotes long-term and proper operation thermal insulation. The vapor barrier must be overlapped and bonded with adhesive tape to subsequent layers. To connect the films, the manufacturer recommends using self-adhesive tape Yutafol SP 1 and SP AL to connect the foil layer.

Yutafol N 110 Special technical characteristics

• Film weight, (density) 110 g/m2;
• Roll 1.5 m wide;
• Length is 50 ±0.3 meters;
• Low flammability corresponds to class B3
• Low vapor permeability within 0.9 grams per square meter in 24 hours;
• Longitudinal/transverse tensile strength 220/190 in N/5 cm
• Water column height, mm 14/22
• UV stabilization is 3 months and requires shelter.

Yutafol N 110 Standard technical specifications

We will say literally two words about this material. The main difference between Yutafol N 110 Standard and the Special series is characterized by the absence of an attenuation reagent. The remaining indicators, characteristics, properties and composition correspond to the series we reviewed above. The roll weight and film density are slightly reduced.

The scope of application coincides with the brand Yutafol N 96 Silver, but this material is denser and provides better tightness and protection. The H 110 Standard series is usually chosen if it is necessary to provide greater strength and insulation characteristics compared to the Silver series. The negative aspect of the film is that it does not have a high fire resistance group.

Vapor barrier film UTAFOL N AL 170 Special

The film Yutafol N AL Special consists of four layers:

Two layers of polyethylene material laminate the mesh;

The third layer in the middle is in the form of a reinforcing mesh, made of strips of polyethylene;

The fourth layer is aluminum foil with a reflective effect;

The reinforcing frame increases strength. An aluminum layer laminated on both sides and foiled with appropriate flooring helps to increase the vapor-tight values. In addition, the foil reflects thermal energy inside the room, retaining precious heat in winter.

Aluminum foil is designed to form a highly vapor-resistant layer on the inside of the thermal insulation. Yutafol N AL Special creates a vapor barrier and promotes long-term and proper operation of thermal insulation. Thanks to the built-in reflective aluminum layer, the vapor resistance is significantly increased. Maintaining an airless layer between the inside and the vapor barrier maintains the high function of the reflective layer.

Yutafol main functions

The membrane guarantees prolongation optimal performance thermal insulation in buildings where they were used. Mainly supporting required values process equilibrium diffusion, maintaining thermal resistance and imparting waterproof properties to the structure.

Based on their characteristics, the membranes guarantee the release of the generated steam into external environment premises. Thus, snow or rain blown by wind currents, as well as condensation accumulations, will not fall from the roof onto the laid thermal insulation.

The use of a membrane prevents moisture insulation materials, which has a beneficial effect on their properties. Humidity leads to the destruction of the material and an increase in thermal conductivity. Consequently, films extend the warranty service life of thermal insulation. In addition to the fact that the air tightness of the structure increases and heat leakage is reduced.

A common question that can be heard from buyers is: which is better, Izospan or Yutafol. Comparing these membranes, we can definitely say that they have the same purpose. However, it seemed to us that the Izospan material contains more information and installation instructions. However, Izospan is a little more expensive, but who will look at the price when the roof of our home is at stake? Believe me, the rework will be much more expensive.

Reinforced vapor barrier

Vapor barrier performs one of the most important functions in preserving everything roofing. If there is no vapor barrier layer in the roof, the under-roof layers are quickly saturated with vapors from the interior, which completely destroys them over time. In addition, such a structure begins to freeze in winter, thaw in spring, and mold, mildew and similar problems appear in it.

But modern technologies It is impossible to imagine the construction of residential buildings without close attention to efficient energy saving. Therefore, insulating materials, which are presented on the market in huge quantities, the most different types and functional purposes. And the TechnoNIKOL company acted quite wisely in this regard, developing only a few solutions, but each of which is universal for its task.

The domestic company TechnoNIKOL is rightfully considered one of the largest international manufacturers of building materials. This company has its own research centers, actively studies world experience and develops new technologies. In total, TechnoNIKOL has its production sites in 7 countries and supplies its products to more than 80 countries.

Specifically for roofing, it produces roll coverings, drainage and polymer membranes, thermal insulation, sealants, soft tiles and even materials for transport and road construction(not only inversion roofs):

Let’s now look at each of these solutions in more detail.

Vapor barrier for pitched roofs: a smart barrier

TechnoNIKOL, such a popular vapor barrier for roofing in Russia, is presented in three versions:

Vapor barrier films

The standard TechnoNIKOL vapor barrier film has a three-layer structure. Its strength and reliability are ensured by both outer layers, which are non-woven propylene sheets. Both serve as a frame for the middle layer - a polypropylene film with a special function of controlling vapor permeability. And all these layers are joined in a factory using low-temperature ultrasonic welding technology.

In addition to standard vapor barrier films, Technonikol has one type of vapor barrier - reinforced. Its basis is a mesh of polyethylene fiber and strips, which are laminated on both sides with film. This mesh gives strength to the material, and double-sided lamination provides the necessary vapor permeability. And to manufacture such products, serious equipment is used:

Superdiffuse membranes

By the way, today it has become quite fashionable to produce materials for construction and repair, which are inherently universal. These combine several functions at once and make the whole job much easier. What is good about TechnoNIKOL vapor barrier: the technical characteristics of its membranes differ significantly from each other.

So what is a membrane? This is a one- or two-layer PVC sheet with a built-in mesh that serves as reinforcement. This fabric has good tensile strength and minimal risk of deformation due to temperature. But be prepared for the fact that there will still be some percentage of moisture through subtle damage to the membrane, poorly sealed joints, or the material itself simply cannot withstand 100% of the steam. But, if you wisely leave a gap above the insulation on the other side of the roof, such a small amount of moisture will easily be removed from it.

Such multilayer vapor barrier protective films and membranes from TechnoNIKOL allow you to preserve not only heat in your living space, but also a healthy microclimate. And he, in turn, will take care of the health of the household and the durability of the furniture and equipment standing inside the room.

In addition to insulated roofs, superdiffuse membranes from TechnoNIKOL are also used to protect cold roofs:

Separately, we note a special type of superdiffuse membranes from TechnoNIKOL - this is Optima. This is a microporous three-layer membrane, especially durable. It ensures the diffusion of water vapor, but does not allow water to pass into the roofing pie. Its special modification is a reinforced membrane.

Foil vapor barrier

Technonikol also has such a fashionable and unusual vapor barrier as reflective. We are talking about the Vapor Barrier membrane. Essentially this is the first domestic material similar type. Compared to foreign analogues, it is also affordable. Such a membrane has high breaking characteristics; it can even withstand the weight of a person and remains intact after the fall of improvised tools. Needless to say, its properties are much better than conventional vapor barrier films.

The Vapor Barrier membrane is self-adhesive, and therefore easy to work with. This vapor barrier is also intended for installation in roof structures that have a load-bearing base made of galvanized profiled sheet. At the same time, its self-adhesive base is recognized as a serious advantage during installation. After all, such material is not only quickly laid, it is also not affected by strong gusts of wind. The repairability of the membrane was also noted. Workers can easily move on such a roof, directly on the membrane, and it can even serve as a temporary roof during a break in work.

And “Vapor Barrier” is produced in the following two versions:

• Vapor barrier “SF 500” – for reliable protection from steam. Also, “Vapor Barrier” 500 allows 4 times less steam to pass through than conventional vapor barrier, but the “SF 1000” vapor barrier material is rightfully considered almost 100% impenetrable.
• Vapor barrier "SF 1000" - for particularly wet rooms. The vapor barrier brand “SF 1000” is intended for rooms with particularly high humidity, such as swimming pools, saunas, baths, and with a500 for absolutely all types of buildings with normal humidity. The breaking characteristics of the vapor barrier are estimated at 600 m 500 n. This vapor barrier can be used in a building with absolutely any fire safety class.

The TechnoNIKOL company has recently been producing a special foil insulation for baths, where the heat-insulating layer itself is covered on both sides with aluminum foil, which simultaneously serves as a reliable vapor barrier! Such slabs are inserted into the sheathing, clamped with slats and facing material, and no additional fastening with films or membranes is needed. At the same time, the insulation turns out to be environmentally friendly, without harmful dust or fumes, and, in addition, it has the highest vapor barrier of all the markets offered. And the slabs are also light, thin, well matched to the standard distance between the rafters.

What to choose for vapor barrier of a pitched roof?

Let's explain in more detail when a film from TechnoNIKOL is needed in a roofing pie, and when a superdiffuse membrane is needed.

You probably know that all heat-saving materials are divided into types according to the nature of their pores, which can be closed or open. The difference is that in closed pores the air does not communicate with the atmosphere, but in open pores it does.

Therefore, if materials with open pores are used as thermal insulation, then it is enough to use a windproof coating - vapor-permeable membranes - to prevent the effects of wind. We are talking about special perforated film membranes that allow water vapor to pass through on one side and retain water from the other. And even if you use a fairly weak vapor barrier on open-cell insulation, but on the other side of the insulation there is a vapor-permeable membrane, then such a design can also be considered competent and reliable.

It is only important, guided by modern SNIPs, to organize natural ventilation using holes in the ridge. In this design, when encountering a vapor barrier, water vapor remains in a significant amount on the other side, and what does leak through easily passes through the insulation, vapor-permeable membrane and is carried out into the atmosphere by the air flow.

Vapor barrier for flat roofs

For vapor barrier of flat and inverted roofs, TechnoNIKOL offers its special products - the weld-on material "Bipol". It is obtained by applying a bitumen-polymer binder filler on both sides on a polyester or fiberglass or base, after which the whole thing is protected on both sides by protective layers: coarse-grained, fine-grained topping and polymer film.

Here are the solutions that implement such vapor barrier:

The Bipol vapor barrier not only protects the roofing pie from steam, but is also resistant to possible mechanical damage, which often arise even right during installation:

Additional accessories: adhesive tapes and tapes

To join films, TechnoNIKOL produces two types of adhesive tapes - butyl rubber and acrylic. Acrylic tape - double-sided, specially developed by TechnoNIKOL for vapor barrier films and membranes. It is made of polyester mesh and coated on both sides special glue on acrylic dispersion. Thanks to all this, this tape is tear-resistant and has high adhesive strength.

In addition, both tapes, acrylic and butyl rubber, comply with EU safety and environmental standards, which is already important:

Features of installing TechnoNIKOL vapor barrier

If you independently undertake the installation of a vapor barrier from this manufacturer, then pay attention to this point: approximately 12-20 cm from the edge of the canvas there is a gray strip, which indicates the vapor-permeable boundary of the film. Photos 6 and 7:

Such a vapor barrier can be mounted either horizontally or vertically, on the inner side of the thermal insulation. If you are attaching the canvas:

• to wooden elements, then use staples from a mechanical stapler or galvanized nails with a flat, wide head;
• to other surfaces such as plastic, glass or metal, then use double-sided joining tape from the same manufacturer. And after fixing the film, be sure to close all the holes with connecting tape.

Thanks to the strength of the films and membranes from this manufacturer, all installation work is easy, neat and does not cause any difficulties.

Reinforced vapor barrier produced by TechnoNIKOL is made of polyethylene high density and consists of three layers, which consist of a reinforcing mesh made of polyethylene strips and laminated on both sides. The mesh gives the material special strength, and lamination on both sides ensures proper vapor permeability. Thanks to the high-quality raw materials included in the product, the film has a long service life comparable to the service life of roofing coverings. The material is not susceptible to rot, mold and small pests. Does not emit harmful substances that have a detrimental effect on human health. Reinforced film protects roofing and other structures from heat loss and the adverse effects of wind. Protects against the penetration of water vapor from the interior into the thermal insulation material, which significantly reduces the concentration of condensate in the thermal insulation layers of the object.

Purpose

Reinforced vapor barrier is used for roofing structures of inclined and flat roofs with any type of ventilation.

Advantages:

• strength and reliability;
• vapor permeability;
• water resistance;
• efficiency;

DESCRIPTION

TechnoNIKOL reinforced vapor barrier consists of three layers: the main one is a reinforcing mesh made of polyethylene strips, which is laminated on both sides plastic film. The reinforcing mesh gives strength to the material, and double-sided lamination ensures vapor tightness.

Svitap 110 N (Vapor barrier film reinforced by TechnoNIKOL)

On the surface of some films, approximately 12 cm from the edge, there is a gray stripe, which, among other things, means a vapor-tight version of the film.
The TechnoNIKOL reinforced vapor barrier has dimensions of 1.5 x 50 m and a density of 110 g/m2. The film, thanks to the raw materials included in its composition, has a long service life, i.e. no less than the roofing coatings used. In addition, it is not susceptible to rot, mold, pests and does not affect health. To prevent damage, the roll is packaged in plastic film.

PURPOSE

TechnoNIKOL reinforced vapor barrier is designed to create a barrier on inner surface thermal insulation of the under-roof attic space on sloping and flat roofs and in the case of internal insulation of the external walls of the facility. It contributes to a significant extent to the preservation of the long-term function of thermal insulation by preventing the penetration of water vapor from the internal space of the object into the thermal insulation, which reduces moisture condensation in the layers of thermal insulation materials. At the same time, this film protects roofing and other structures from heat loss and leaks, retains heat eo indoors and protects against the adverse effects of wind.

APPLICATION

TechnoNIKOL reinforced vapor barrier can be combined with TECHNO insulation and TECHNOPLEX polystyrene-based materials. Can be used for both ventilated and non-ventilated roof structures, for sloped and flat roofs.

INSTALLATION METHOD

TechnoNIKOL reinforced vapor barrier is fixed both horizontally and vertically on the inside of the thermal insulation to load-bearing wooden elements using mechanical stapler staples or galvanized flat-head nails. Fastening to wooden load-bearing elements and to other materials (metal, glass, plastics, etc.) can also be carried out using double-sided connecting tape. It is recommended to close all holes that appear when attaching the film with connecting tape. TechnoNIKOL reinforced vapor barrier can be laid on either side. Individual strips of film must be hermetically connected not only to each other, but also to adjacent structures or to prominent building elements(antenna stands, ventilation pipes, chimney, roof windows, etc.) using connecting tapes TechnoNIKOL. Attaching a vapor barrier to skylights should be carried out according to the recommendations of their manufacturers because Various manufacturers of roof windows offer various solutions attaching films to your products. During installation of the film when installing hems, drywall or decorative material it is recommended to lay wooden slats or other profiles so that the holes from the fasteners would form in these materials, and not in the vapor-tight barrier. If the above rules are not followed, leaks occur through the joints, which very quickly reduces the effectiveness of preventing the penetration of water vapor. In this case, problems arise associated with moisture condensation in thermal insulation, heat leakage channels, water vapor and other troubles caused by unwanted condensation appear. When installing a feather-tight barrier in flat roofs, it is necessary to remember the danger of damage to the film by the material adjacent to it from above or below, so you should correctly organize the order of the layers of the roofing cake.

• Thermal insulation is considered an effective way to reduce heat loss in a room. As a rule, it is laid at the junction of ceilings and walls. However, the insulation itself also needs protection from moisture penetration.

  To protect the thermal insulation from getting wet, a vapor barrier film for the roof is used. The following physical processes take place in the under-roof space. An incredibly large amount of moisture accumulates in any premises, especially residential ones. When the outside temperature drops, due to a significant difference in the outside and inside temperatures, the process of moisture condensation begins, which settles on various surfaces: ceiling, walls and others.

  The penetration of moisture into thermal insulation has a rather negative effect on its performance.

  On a note

  It is worth noting that when the insulation is moistened by about 2.5%, its thermal insulation characteristics are reduced by almost half. The surface behind layers of insulation becomes an easy target for fungus.

  Vapor barrier film, the purpose of which is precisely to solve these problems, is usually equipped with micro-perforation. On the one hand, it releases steam from the thermal insulation to the outside, on the other hand, it reliably protects the insulating layer from the penetration of moisture from the outside and protects living spaces from the ingress of silicate fibers found in some insulation materials, which are harmful to human health.

  Types of vapor barrier films, properties

  

  The need for insulation of this kind, as well as waterproofing, is spelled out in building codes. According to GOST, the vapor barrier film must have the following indicators:

  • Weight. Its value and the value of density, an indicator of insulation strength, are directly proportional. Strong material is not only convenient to work with, but also better resists the effects of gravity.
  • Vapor permeability. Its performance properties improve as this indicator decreases. For residential premises in Russian conditions, brands are suitable whose vapor permeability is significantly less than 1 g/sq. m.

  The choice of vapor barrier is a crucial moment. We must not forget that technical polymers may contain various additives, for example, plasticizers or ultraviolet radiation stabilizers, which contribute to the accumulation of harmful substances in a confined space. It also cannot be ruled out that the product was made from low-purity base raw materials.

  Determining the harmfulness of a vapor barrier material is quite simple. If you roll out a roll in a closed, warm room, the low-quality film will begin to release specific smell, which is impossible not to feel the next time you visit the room.

  Varieties for roofing

  • Polyethylene vapor barrier film. One of the most popular insulation options. Despite the fact that it is cheaper than others, this option is quite effective. As a rule, the material is reinforced, for which a special reinforcing mesh or fabric is used.

  There are:

  • perforated, equipped with micro-holes that provide vapor permeability. However, its level does not meet the standard, so the presence of a ventilation gap in the roofing pie is mandatory;
  • smooth (non-perforated) - when installing them, use a special tape for vapor barrier film, which is used to connect individual sheets;
  • vapor barriers They have fairly high performance qualities, and also reflect heat back.

  Attention!

  Laminated insulation is not suitable for vapor barrier in rooms with a normal microclimate. They are widely used in the arrangement of premises with high humidity, for example, saunas or swimming pools.

  Comparison table for vapor barrier films

  

  • Polypropylene. They are distinguished by a very high level of strength and resistance to ultraviolet radiation. Particularly in demand are materials with an anti-condensation layer made of viscose with cellulose, which absorbs and retains moisture. The advantages of such a layer are obvious: it not only completely absorbs moisture, but also dries instantly naturally as soon as the causes of condensation disappear.
  • Diffusion membranes. This is a synthetic non-woven material. It is much more effective than polyethylene or polypropylene products. True, their cost is much higher.
  • Liquid rubber . This is a cold emulsion of polymers that is sprayed over the surface using special equipment. The undoubted advantage of this option is the ability to use this type of vapor barrier in roofing structures that have even the most intricate shape.

  Manufacturers

  The best results are usually achieved special materials. Of course, unlike ordinary polyethylene, which is also used for vapor barrier, the price per m 2 of vapor barrier film is higher, but the thermal insulation will be better protected and for a much longer period. Of course, the manufacturer’s brand plays an important role when choosing.

  Technical characteristics of vapor barrier film: TechnoNIKOL, Yutafol, Izospan, Ecolife

  Let's look at the most common ones today Russian market high-quality vapor barrier films, the prices of which are quite reasonable.

  Film Yutafol

  Several materials can be highlighted in the manufacturer’s line:

  • 3-layer non-flammable vapor barrier film Yutafol Special series H 110. The first layer is reinforced mesh, which gives the material strength. A layer of lamination is applied to it on both sides. Low flammability is due to the presence of a special reagent in the membrane composition. Material density – 110 g per cubic meter. m. Used to construct a vapor barrier in attic spaces, V roofing pies flat and pitched roofs.
  • The Yutafol Standard film from the same series is similar in its technical characteristics to the previous version, however, it does not contain a self-extinguishing reagent. Accordingly, it is included in a different price category.
  • NAL Special series 170 has four layers. To the three existing ones, aluminum is added, applied on one side. The density of this material is the highest - about 170 g per sq.m.

  

  The advantages of Jutafol, as a rule, include the following characteristics of the material: it

  • universal, that is, suitable for installing a vapor barrier for walls and roofs;
  • protects against the formation of fungal mold on surfaces in the under-roof space and directly on the roof;
  • increases the service life of the structure;
  • improves ventilation of the under-roof space;
  • has simple installation.

  Among the shortcomings we note:

  • exposure to ultraviolet rays;
  • single-layer samples have a non-uniform structure;
  • In the process of creating reinforced products, it is possible that microcracks may form, which may affect their characteristics.

  TechnoNikol

  This is the most popular material of this type today. It is environmentally friendly, fireproof, and fully complies with GOST requirements and safety standards. Thanks to its three-layer structure, it reliably protects the roof from condensation, and the insulation from the accumulation of dust and absorbs noise. Excellent strength and moisture resistance properties allow the insulation to be laid directly on a rough or rough surface, for example, rough wood or metal.

  

  The structure of the TechnoNikol vapor barrier film for various types roofs are different:

  • for pitched slopes - a diffusion film consisting of polymer membrane, enclosed between two layers of non-woven fabric based on polypropylene;
  • for flat ones - lay perforated and non-perforated film. The first option, consisting of a number of reinforced layers, is more durable. Due to the large number of micro-holes, the material “breathes”. Its texture allows for effective removal of vapors and protects the premises from the penetration of dust and excessive humidity, creating, one might say, an ideal microclimate there.

  

  Special mention should be made of the two-layer universal vapor barrier film TechnoNikol. Its moisture-vapor-proof qualities are ensured by a special structure - it is polypropylene fabric, coated on one side with a polymer film. The exceptional strength of the material allows it to be used as a temporary roofing covering that can withstand significant snow loads. This is an environmentally friendly, chemically and biologically neutral material.

  Its advantages include:

  • optimal price-quality ratio of TechnoNIKOL vapor barrier film. In terms of cost, they belong to the average category.
  • environmental friendliness - only materials that do not have toxic emissions are used in production.

  Izospan

  The technical characteristics of this manufacturer’s line are summarized in the table below:

  The advantages of Isospan vapor barrier include the following qualities:

  • sufficiently high strength;
  • increased water repellency;
  • resistance to fungus and mold formation;
  • possibility of operation in a wide temperature range, ranging from -60°C to +80;
  • ease of installation;
  • environmental friendliness;
  • The stated service life is up to half a century.
