Vapor barrier reinforced TechnoNIKOL. Technical characteristics and methods of installation of TechnoNIKOL vapor barrier in insulation systems TechnoNIKOL vapor barrier technical characteristics

Application thermal insulation materials based on mineral and basalt wool determines the use of vapor barrier films to reliably protect the insulation layer from moisture. TechnoNIKOL vapor barrier is moisture resistant and perfectly protects thermal insulation from vapors. The film can be used to install warm roofs and insulate facades. Let's take a closer look at all the properties and characteristics in this article. vapor barrier film TechnoNIKOL.

The main purpose of vapor barrier films is to protect insulation from moisture and ensure moisture balance in a living space. TechnoNikol has a three-layer structure that can reliably protect the insulation “pie” from the formation of condensation. Technical characteristics of TechnoNIKOL vapor barrier correspond to all modern building regulations, like .

1 . Diffusion membranes is a superdiffusion film made of polymer membrane and two layers of non-woven polypropylene fabric. When creating a vapor barrier between layers, it creates reliable barrier water vapor. This film is durable and can withstand heavy loads; it is used for pitched roofs, insulated walls and for interfloor ceilings.

2 . Perforated vapor barrier for flat roof made of polyethylene, the vapor barrier is highly durable and can withstand heavy loads and large amounts of moisture. TechnoNIKOL perforated film has many holes through which moisture is released out. This vapor barrier provides excellent protection from the inside and between floors.

3 . The universal vapor barrier film consists of two layers of polypropylene with polymer coating. Their increased strength makes them suitable for flat roofs and pitched roofs. We have already looked at what Geotextiles and universal films are. They are used as under-roof wind and moisture insulation to protect the thermal insulation layer from wind and precipitation.

4 . Reinforced vapor barrier for flat roofs made of perforated and non-perforated film. It's breathable, more durable material With big amount microholes made of several layers of reinforced film. TechnoNIKOL protects the room from humidity; thanks to its characteristics, it removes vapors from thermal insulation and helps create a favorable microclimate in the house.

In the absence of a water barrier, moisture penetrates into the thermal insulation layer on the floor, where it condenses, turning into water.

Advantages of TechnoNIKOL film

The main thing to consider when choosing a vapor barrier is the type of surface being treated. For a pitched roof, it is better to use the TechnoNIKOL superdiffusion membrane; for a flat roof, you should choose a perforated film. Before purchasing, you should ask the seller for a TechnoNikol vapor barrier certificate, so as not to accidentally buy a counterfeit of this product in the store.

The advantages of TechnoNIKOL vapor barrier include:

1. Excellent price-material quality ratio;
2. Environmentally friendly: the material does not emit harmful toxins;
3. Versatility: used for roofing and thermal insulation.

Vapor barrier TechnoNIKOL technical characteristics

All of the above types of vapor barrier from TechnoNikol guarantee you comfortable indoor humidity levels. Due to their structure, films have optimal parameters vapor permeability and strength. Among the properties and technical characteristics, it should be noted a wide temperature Range applications from -100 to +60 °C, environmental friendliness and UV resistance.

Modern construction impossible to imagine without thermal insulation. Thermal insulation materials are increasingly used in the construction process. But even the highest quality insulation will not work effectively throughout its entire service life. TechnoNIKOL vapor barrier plays an important role in preventing the formation of moisture on the thermal insulation material.

Features and Benefits

TechnoNIKOL vapor barrier prevents the impact of steam on the roof. Due to its vapor and water resistance properties, it prevents the penetration of moisture into the structure. Thus, the vapor barrier regulates the temperature and water balance in a buiding. Its multilayer structure not only reliably protects the roof from condensation, but also prevents the accumulation of dirt and protects against noise. The main advantages of TechnoNIKOL vapor barrier include the following:

• simple installation;
• availability of material. Rolls can be purchased at any specialized store or ordered online;
• reliability, durability and resistance to impacts external factors: minimal risk of material deformation;

• price corresponding to quality. Price for one square meter belongs to the average category of pricing policy;
• high environmental friendliness of the film. The vapor barrier contains only those materials that do not form toxins and harmful components. As a result, vapor barrier materials are widely used - from public buildings to residential premises;
• versatility. The material is used not only for roofing, but also to protect the surface of walls from condensation.

But there are also disadvantages of this material, such as:

• strong tension of the film can lead to its destruction due to temperature changes;
• Ready-made mastic can only be used when treating surfaces before laying or installing the final decorative finish. Otherwise, the film will allow air to pass through and also retain liquid.

Description

Vapor barrier material"TechnoNIKOL" is a perforated or membrane film. It is available in rolls. WITH outside The roll is marked with a gray line 12 cm from the edge, which guarantees vapor tightness. The material is absolutely safe for health and lasts for a long time. for long years and is not affected by environmental factors. Vapor barrier "TechnoNIKOL" has the following technical characteristics:

• vapor permeable properties: from 1 to 5 g/m² x day;
• material density: 80–120 g/m²;
• withstand force in width and length: up to 180 N/5 cm;

• resistance to impact ultraviolet rays: up to 3 months;
• operating temperature: up to 70 degrees.

The technical characteristics of the film comply with all fire and explosion safety certificates since the film is non-flammable. Construction experts advise using TechnoNIKOL especially for flat roofs.

Since the vapor barrier has increased strength and resistance to moisture, as a result it can be used for wooden or metal roofs with roughness.

Varieties

TechnoNIKOL vapor barrier is classified depending on the type of roof. Vapor barrier for pitched roofs presented in several solutions:

• Vapor barrier films have a three-layer structure, two layers are responsible for the reliability and strength of the material. They are made from laminated propylene fabric. The third layer is designed to control vapor permeability. These layers are connected to each other using cold welding. The notorious advantages of such films are considered increased strength and resistance to ultraviolet radiation. They can protect exposed rafters from snow and rain throughout the year.

There is another type of universal film - reinforced (a combination of perforated and non-perforated membranes), which is made from polyethylene. Due to such material properties as strength and vapor permeability, reinforced films have found wide application in construction.

Polyethylene has a loose structure and often has defects due to the presence of foreign components in the raw materials and dust ingress during production. To produce such a vapor barrier, special equipment is used.

• Bag fabrics are made from polyethylene threads, which are laminated with a low-density polyethylene melt. Such a product does not have vapor barrier properties, since the polyethylene melt unevenly laminates the initially uneven base. But this does not prevent the use of bag fabrics when installing cold roofs as under-roof waterproofing.

• Superdiffusive double-layer membranes perform several functions at once, which facilitates the construction process. The membrane is a polyvinyl chloride fabric with a built-in mesh, which serves as reinforcement. PVC imparts high strength and minimizes the risk of deformation during temperature changes. However, you need to be prepared for the fact that if the membrane is damaged, moisture will enter the room. This can be prevented by sealing the joints well and leaving a gap above the insulation to allow moisture to drain out on its own. Membrane films retain heat in the room and also create the necessary microclimatic conditions.

• Foil vapor barrier has unique properties. It is practically not subject to deformation, even when tools fall. Foil film is also considered reflective. Thus, its properties are much better than other vapor barrier materials.

A striking example of foil self-adhesive water vapor barrier is considered "Vapor barrier". It is used for roofs with a load-bearing base using corrugated sheets. The main advantage of such a vapor barrier is its self-adhesive base. Since this will not only speed up the process of laying the material, but also will not harm the roof during operation strong winds. We must not forget about the maintainability of the foil membrane. Workers can walk on the roof safely. During breaks in work, it can also serve as a temporary roof.

Vapor barriers for flat roofs are made by applying a bitumen polymer to a fiberglass or polyester backing. It is suitable for uninsulated roofs. Coating vapor barrier is also used to treat the surface of floors and walls. In this case, heated mastic is used.

Dimensions

The vapor barrier sheet for a flat roof has the following dimensions: 3x30 m and a thickness of 0.3, and for pitched roofs and walls - 1.5x50 m and a thickness of 0.15.

When planning the organization of roofing vapor barrier, it is worth considering the type of roof. Usually for pitched type apply membrane materials, and for flat ones - perforated. Before purchasing, be sure to check the vapor barrier certificate. This is done in order to avoid purchasing a fake. Experts recommend using TechnoNIKOL thermal insulation if the roof is insulated with ordinary material that can absorb moisture.

It is worth adhering to several basic rules for installing the TechnoNIKOL vapor barrier material:

• When using double-sided film, where one side is rough and the other is smooth, the film is laid on the insulation with a smooth surface. The other side of the film, when in contact with condensate, will allow it to evaporate unhindered. Otherwise smooth surface It will only accumulate moisture. Its main function is to protect the surface by preventing the steam accumulated by the rough surface from passing through.

• When working with polypropylene material They are also placed in one layer with the smooth surface inward.
• When working with foil material, keep in mind that the foil must reflect the sun's rays. Therefore, such a film is laid with the foil facing out.
• If it is necessary to lay insulation vertically, it is necessary to calculate that the joint coincides with the sheathing, otherwise the vapor barrier may tear, even if it is glued with tape.

All these rules can be applied in almost all cases, but each manufacturer makes some changes, so before installing a vapor barrier, you must read the instructions. At correct installation vapor barrier material can prevent the appearance of mold and mildew.

The installation method differs depending on which part of the room you need to install the vapor barrier film.

Roof vapor barrier

To properly install a vapor barrier film on the roof, you need to follow some recommendations. So, rolls with vapor barrier material are rolled out, starting from the top and pushing the next layer onto the previous one by 2–4 cm. For alignment individual parts tape is used to help seal the seams. Typically, aluminum tape or rubber tape are used as such tape. To vapor barrier an uninsulated roof, the material is attached to the sheathing horizontally.

Ceiling vapor barrier

When installing a ceiling vapor barrier, it is necessary to prepare the surface. To do this, wipe off the dust from the surface and leave it until completely dry. Then they move on to eliminating irregularities and grooves using a primer mixture and wait for it to dry. To avoid the appearance of uneven areas where moisture accumulates, a vapor barrier film must be stretched on the ceiling. To do this on ceiling beams The material is glued with tape. The film pieces are overlapped and the joints are sealed with tape. Nails are nailed along the joint line every 40 cm. Instead of nails, you can use a furniture stapler, which securely fixes the material to the surface.

Ceiling vapor barrier material is attached using slats together with insulation or separately. The slats are also screwed every 40 cm. Most often in construction stores you can find sheet films for the ceiling. To install them you need to purchase a special profile. In this case, a frame is attached to the ceiling, a vapor barrier sheet is installed, and then insulation is installed.

To protect the roof from condensation and preserve the insulation, a special type of insulation in the form of a moisture-resistant barrier is required. Great reviews has products famous manufacturer TechnoNIKOL insulation products that meet building standards in terms of fire safety and harmlessness and are characterized by high quality and affordability. In addition to the main function - maintaining the temperature and humidity in the room at the desired level, this material protects against noise and dust accumulation. On average, the price per m2 of vapor barrier ranges from 14 to 23 rubles (depending on strength, permeability and intended purpose).

The TechnoNIKOL vapor barrier is thin film: perforated or membrane, available in rolls. On the outside it is marked - a gray line 12 cm from the edge, confirming the presence of vapor-proof properties. Vapor barrier in a three-layer design, with or without reinforcement in the form of a thin mesh of polyethylene strips. The material is not subject to biological influences, is safe for health, and has a long service life.

6. Safety of use: TechnoNIKOL is made from environmentally friendly raw materials and does not emit toxins.

Description of the installation process

The main condition is to increase the vapor permeability of materials when moving from a warm surface to a colder one, that is, the film is placed on the inside of the walls or roof. When working with Technonikol vapor barrier for pitched roofs, it is deployed directly on the rafters and secured with galvanized nails with umbrellas or a construction stapler. TechnoNIKOL strips are laid horizontally with an overlap of at least 15 cm, vertically - about 20, the longitudinal line on the film serves as a guide. The edges and joints must coincide with the rafters, and the material itself must be smooth (without folds) and slightly sag in the center (no more than 2 mm). A small groove is provided around the perimeter of the lower edge to drain away flowing moisture.

When insulating walls, TechnoNIKOL film is laid directly on the insulation, the smooth side facing the inside of the room. The minimum overlap is 10 cm, the joints are secured with staples or nails with wide heads. When insulating flat roofs, TechnoNIKOL panels are placed directly on the surface of the ceiling (even on concrete) and placed on the edge of the wall by 20–25 cm; for reliable adhesion, it is allowed to use a special adhesive composition. All possible joints (near pipes or ventilation ducts) are covered with sealing tape. Ventilation must be provided: for frames with subsequent decorative finishing- from 3 cm, for roofs - from 4, it is desirable that the design includes one common hood.

Price

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.

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, unpleasant odor.

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 multilayer structure, thanks to which it achieves optimal performance vapor permeability and high strength.

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 flat roofs, having high strength and elasticity;
• reinforced, reinforced three-layer film high strength;
• universal, suitable for all types of roofs.

Physical and mechanical characteristics of TechnoNIKOL vapor barrier films

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 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 pitched roof

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 element protection flat roof from the steam that forms 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.

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.

Durable reinforced vapor barrier

Specifications:

• 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 attic spaces, attics, 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 small and multi-storey 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 next layer roofing or insulating “pie” to minimize exposure to UV rays.

The affordable cost of TechnoNIKOL is the reason for its popularity among private developers and construction companies. Prices different kinds films 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, with inside insulation under finishing premises.
2. As a vapor barrier layer in uninsulated attics.
3. During installation external system wall insulation, residential attics, floors.

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 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, drywall, cork panels.

Important! Between interior decoration And vapor barrier layer a ventilation gap of at least 3 cm must be provided.

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 made of wooden slats and then 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.

When choosing this vapor barrier, be sure to pay attention to the characteristics of the insulated surface and buy the material that best matches its type: pitched or flat roof, wall or insulated attic.

The roof needs reliable protection from condensation, and thermal insulation materials are sometimes not enough. What to do? A special film comes to the rescue, which is moisture resistant, thanks to which it perfectly preserves roof insulation. Nowadays, the most popular vapor barrier is TechnoNikol. Its environmental, fireproof and other qualities are in accordance with established standards.

Purpose and technical characteristics

Vapor barrier TechnoNikol protects the roof structure from the steam that forms indoors. Its water- and vapor-tight properties minimize water penetration into structures. TechnoNikol vapor barriers are designed to regulate the balance of moisture and temperature in the room. Its three-layer structure provides reliable protection roofs from the formation of condensation, and also eliminates the accumulation of dust in the insulation and protects against noise.

When studied, the technical characteristics of vapor barriers indicate compliance with safety standards. Professional builders recommend TechnoNikol vapor barrier for use in flat roofing systems. They indicate the high strength and moisture resistance of the TechnoNikol film, due to which it can be used directly on the rough and rough surface of rough wood or metal.

Types of TechnoNikol film

This or that type of vapor barrier is used depending on the type of roof. It is classified as follows:

Main advantages

Film vapor barrier TechnoNikol has next distinctive features , favorably emphasizing its advantages:

• The pricing policy is in excellent balance with quality. The cost per m2 can be classified as an average price category.
• The film is highly environmentally friendly. In its production, no materials are used that emit toxins and other harmful substances. Therefore, the film is used for arranging public buildings, as well as residential buildings.
• Versatility of use. The film is used not only for horizontal roofing work, but also to protect vertical surfaces, that is, walls from the formation of condensation.

TechnoNikol film selection and installation

The first thing to consider when choosing a vapor barrier is roof type. TechnoNikol roll-type vapor barrier material is used when the roof is equipped with conventional insulation that absorbs moisture. The most important factor What you need to consider when choosing a vapor barrier is the certificate. Be sure to ask before purchasing this document from the seller, its presence will protect you from counterfeits.

The vapor barrier film is installed in such a way that the smooth surface is directed inward. It is fixed using a special compound, which can be purchased at the same place where the film is sold.

The film is placed overlapping vertical or horizontal stripes. The film should be distributed evenly, making sure that all parts of the frame are covered. It also needs to be lowered onto the walls by about 25-30 centimeters.

What is the price of vapor barrier?

The cost depends on the type of vapor barrier material. Price per roll 1.5 x 50 m is in the following range:

• The price of vapor barrier for pitched roofs Optima Membrane is in the range from 2,150 to 2,500 rubles.
• Perforated film for flat roofs has a price of about 2,700 to 2,800 rubles.

So, from the above material we can conclude that the technical characteristics of the vapor barrier are such that they allow the film to be used directly on untreated rough surfaces without causing any damage to her. Also, TechnoNikol vapor barrier is able to cope with its tasks perfectly not only in conditions of pitched roofs, but also in high humidity flat roof.
