Film reinforced technonikol. Vapor barrier film: types and specifications. Features of the vapor barrier film

Reinforced vapor barrier manufactured 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 extra strength, and the lamination on both sides ensures proper vapor permeability. Due to the high-quality raw materials included in the product, the film has a long service life comparable to the operational life of roofing. The material is not subject to rotting, mold and the effects of small pests. Does not highlight harmful substances that have a detrimental effect on human health. Reinforced film protects roofing and other structures from heat losses and 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

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

But modern technologies construction of residential buildings is impossible to imagine without close attention to efficient energy saving. Therefore, especially carefully and thoughtfully selected insulating materials which are on the market in huge number, most different types And functional purposes. And TechnoNIKOL acted quite wisely in this regard, having developed 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 building materials. This company has its own research centers, actively studying world experience and developing new technologies. In total, TechnoNIKOL has its production sites in 7 countries of the world and provides its products to more than 80 countries.

Specifically for the roof, she releases roll coatings, drainage and polymer membranes, thermal insulation, sealants, soft tiles and even materials for transport and road construction(not only inverted roofs):

Let's take a closer look at each of these solutions.

Vapor barrier for pitched roofs: a thoughtful barrier

Such a vapor barrier for TechnoNIKOL roofing, popular 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 provided by both outer layers, which are non-woven propylene sheets. Both serve as a frame for the middle layer - polypropylene film with a special vapor permeability control function. And all these layers are connected in the factory using the technology of low-temperature ultrasonic welding.

In addition to standard vapor barrier films, TechnoNIKOL has one type of vapor barrier - reinforced. It is based on a mesh of polyethylene fiber and strips, which are laminated on both sides with a film. Such a mesh gives strength to the material, and double-sided lamination - the necessary vapor permeability. And for the manufacture of such products, serious equipment is involved:

Super diffuse 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 greatly facilitate all the work. What is good vapor barrier TechnoNIKOL: specifications its membranes differ significantly from each other.

So what is a membrane? This is a single or double layer PVC sheet with an embedded mesh that serves as reinforcement. In such a canvas - good strength rupture and minimal risk of deformation due to temperature. But be prepared for the fact that all the same, some percentage of moisture through subtle damage to the membrane, poorly sealed joints, or the material itself simply cannot withstand all 100% of the steam. But, if you correctly left a gap above the insulation on the other side of the roof, such a small amount of moisture can easily be removed from it.

Such multilayer vapor barrier protective films and membranes from TechnoNIKOL allows you to keep in the living room not only heat, but also a healthy microclimate. And he, in turn, will take care of the health of the household and the durability of the furniture with appliances inside the room.

In addition to the insulated roof, TechnoNIKOL superdiffuse membranes are also used to protect cold roof:

Separately, we note special kind superdiffuse membranes from TechnoNIKOL is Optima. It is a microporous three-layer membrane, especially durable. It allows the diffusion of water vapor, but does not allow water to pass into roofing cake. 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 membrane "Varobarrier". In fact, this is the first domestic material of this type. Compared to foreign counterparts, it is also affordable. Such a membrane has high breaking characteristics, it even withstands the weight of a person and remains intact after the fall of improvised tools. Needless to say, in terms of its properties, it is much better than conventional vapor barrier films.

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

And the "Varobarrier" is produced in the following two versions:

• Vapor barrier "SF 500" - for reliable protection from steam. Also, "Varobarrier" 500 passes 4 times less steam than a conventional vapor barrier, but the material of the "SF 1000" vapor barrier is rightfully considered almost 100% impermeable.
• Vapor barrier "SF 1000" - for especially wet rooms. Vapor barrier brand "SF 1000" is designed for rooms with special high humidity these are pools, saunas, baths, and with a500, absolutely for all types of buildings with normal humidity. The bursting characteristics of the vapor barrier are estimated at 600 m 500 n. Such a vapor barrier can be used in a building with absolutely any fire safety class.

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

What to choose for the vapor barrier of a pitched roof?

Let's explain in more detail when a TechnoNIKOL film 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 are closed and open. The difference is that in closed pores the air does not communicate with atmospheric air, but in open ones 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 on the other. And even if you use a rather weak vapor barrier on an open-pore 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, meeting with a vapor barrier, water vapor remains in a significant amount on the other side, and what nevertheless leaked out easily passes through the insulation, vapor-permeable membrane and is carried out into the atmosphere by air flow.

Vapor barrier for flat roofs

For the vapor barrier of flat and inverted roofs, TechnoNIKOL offers its own special products - the built-up material "Bipol". It is obtained by double-sided application of bitumen-polymer binder filler on a polyester or fiberglass or base, after which all this is protected on both sides with protective layers: coarse-grained, fine-grained dressing and polymer film.

Here are the solutions in which such vapor barrier is implemented:

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

Optional accessories: adhesive tapes and adhesive tapes

To connect films, TechnoNIKOL produces two types of adhesive tapes - butyl rubber and acrylic. Acrylic tape- double-sided, specially designed 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, such a tape is resistant to tearing and has a high bonding strength.

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

Features of installation of TechnoNIKOL vapor barrier

If you yourself undertake the installation of a vapor barrier from this manufacturer, then pay attention to this moment: about 12-20 cm from the edge of the canvas there is a gray strip that indicates the vapor-permeable border of the film. Photos 6 and 7:

Such a vapor barrier can be mounted both horizontally and vertically, on the inner side of the thermal insulation. If you attach 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 a double-sided adhesive tape from the same manufacturer. And after fixing the film, be sure to close all the holes with a connecting tape as well.

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

DESCRIPTION

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

Svitap 110 N (Reinforced vapor barrier film TechnoNIKOL)

On the surface of some films, about 12 cm from the edge, there is a gray stripe, indicating, among other things, a vapor-tight version of the film.
Reinforced vapor barrier TechnoNIKOL has dimensions of 1.5 x 50 m and a density of 110 g/m2. The film, due to the raw materials included in its composition, has a long service life, i.e., no less than those used roof coverings. In addition, it is not subject to rotting, mold, pests and does not affect health. To prevent damage, the roll is packed in a polyethylene film.

PURPOSE

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

APPLICATION

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

MOUNTING METHOD

Reinforced vapor barrier TechnoNIKOL is fixed both horizontally and vertically on inside thermal insulation to load-bearing wooden elements with staples of a mechanical stapler or galvanized nails with a flat head. Fastening to wood load-bearing elements and to other materials (metal, glass, plastics, etc.) can also be carried out with a double-sided connecting tape. It is recommended to close all the holes that have arisen during the fixing of the film with a connecting tape. Reinforced vapor barrier TechnoNIKOL can be installed on either side. Separate film strips must be hermetically connected not only to each other, but also to adjacent structures or to prominent building elements (antenna stands, ventilation pipes, chimney, skylights, etc.) using TechnoNIKOL connecting tapes. Attaching a vapor barrier to skylights should be carried out according to the recommendations of their manufacturers. various manufacturers skylights offer various solutions attaching films to their products. During installation of the film when installing binders, drywall or decorative material it is recommended to run wooden laths or other profiles so that the holes from the fasteners are formed in these materials, and not in the vapor barrier. If the above rules are not observed, leaks occur through the joints, which very quickly reduces the effectiveness of preventing the penetration of water vapor. In this case, there are problems associated with the condensation of moisture in the thermal insulation, there are channels for the leakage of heat, water vapor and other troubles caused by unwanted condensation. In the case of installing a feather-tight barrier in flat roofs, it is necessary to remember the risk of damage to the film by the material adjacent to it from above or below, so the order of the layers of the roofing cake must be properly organized.

To protect the roof from condensation and the safety of the insulation, a special type of insulation is required in the form of a moisture-resistant barrier. Products have excellent reviews well-known manufacturer products for insulation TechnoNIKOL, corresponding building standards in terms of fire safety and safety and different high quality and accessibility. In addition to the main function - maintaining the desired level of temperature and humidity in the room, given 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 purpose).

The TechnoNIKOL vapor barrier is thin film: perforated or membrane, produced in the form of rolls. WITH outer side it is marked with a gray line 12 cm from the edge, confirming the presence of vapor barrier 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, has long term operation.

Main technical characteristics of TechnoNIKOL vapor barrier:

• vapor permeability (a value that controls the passage of steam): from 1.1 to 5 g / (m²∙day);
• film density: from 80 to 110 g/m2;
• tensile strength: up to 170 N/5 cm, characterizes the greatest withstand force along the length and width. In this case, the relative elongation at break reaches 260%;
• insulation resistance to ultraviolet radiation - from 1.5 to 3 months (TechnoNIKOL film can be bought for the purpose of temporary replacement of the roof for the period of repair, while it will not lose its useful properties);
• maximum operating temperature: 70 °C.

Varieties of vapor barrier

Products are represented by three brands:

1. Produced in the form of a multilayer polyethylene film with high hydrophobic properties, a vapor barrier for flat roofs TechnoNIKOL. This type placed under the insulation to minimize the ingress of moisture into the enclosing structures.

2. Reinforced vapor barrier with an inner mesh of dense polyethylene strips and an outer laminated film. Designed to create a vapor barrier on the inside of the insulation under the roof of both pitched and flat roofs. Retains heat, prevents the ingress of condensate from the interior of the attic into the thermal insulation, protects from wind.

3. Universal - vapor barrier for roofing TechnoNIKOL Optima for pitched roofs And frame walls. The inner layer is a diffuse membrane (unlike the polyethylene of the previously mentioned brands), due to which a higher vapor permeability is achieved (the “steam room” effect is excluded).

Benefits of using

The advantages of TechnoNIKOL vapor barrier include:

1. Easy to install roll film.

2. Strength, performance stability and resistance to external influences: the risk of damage to the middle layer is minimal. Reliable adhesion of the layers is ensured unique technology TechnoNIKOL - ultrasonic cold welding.

3. Versatility: the material is suitable for any type of floors and vertical structures.

4. Creation of a comfortable temperature and humidity balance corresponding to the characteristics wooden house(especially relevant for TechnoNIKOL Optima membrane insulation).

5. Availability. Vapor barrier prices are average, you can simply buy rolls at any building supermarket or order on the Internet, there are no problems during transportation.

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 an increase in 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 unfolds directly on the rafters and is fixed 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 should coincide with the rafters, and the material itself should be even (without folds) and slightly sag in the center (no more than 2 mm). A small groove is provided along the perimeter of the lower edge to drain flowing moisture.

When insulating walls, the TechnoNIKOL film is placed directly on the insulation, the smooth side is turned into the room. The minimum overlap in this case is 10 cm, the joints are fixed with staples or nails with wide hats. When insulating flat roofs, TechnoNIKOL panels are placed directly on the floor surface (even on concrete) and led to 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 glued with sealing tape. Ventilation is necessarily provided: for frames with subsequent decorative trim- from 3 cm, for roofs - from 4, it is desirable that the design provides for one common hood.
