TechnoNIKOL vapor barrier is the general name for all films designed to provide protection from moisture. In fact, each film has its own purpose, and the manufacturer, the TechnoNIKOL company, understanding the difference, offers the consumer, depending on the purpose, to choose a TechnoNIKOL vapor barrier from four types:

• TechnoNIKOL vapor barrier for sloping roofs, partially permeable to steam;
• for horizontal roofs, with increased strength and high elasticity rates;
• three-layer TechnoNIKOL vapor barrier reinforced with reinforcement of the highest strength;
• universal - comprehensive solution all tasks for protecting building materials from moisture.

Modern construction projects It’s impossible to imagine without thermal insulation. Thermal insulation materials literally envelop buildings, but the highest quality insulation will not be able to work effectively over a long period of time if it itself is not protected from the destructive effects of moisture. Let's see how TechnoNIKOL vapor barrier will help us with this.

TechnoNIKOL vapor barrier for roofing:

TechnoNIKOL vapor barrier for roofing has an extremely important function in preventing the occurrence of condensation moisture on thermal insulation materials laid to increase the thermal conductivity coefficient of the roof. The creation of such a vapor barrier is a fundamental step for the construction of warm and comfortable housing. Especially considering the frequent and sudden changes temperatures in climatic zone our residence.

TechnoNIKOL vapor barrier reliably protects the roof. Of course, if there were no installation errors during the work. The use of even the highest quality vapor barrier will lose all meaning if it is done irresponsibly.

Thermal insulation material will soon lose its multifunctional properties; most likely, the housing will become damp, developing a favorable environment for the formation of mold and mildew. That is why, when arranging the roof, it is important to perform two tasks:

1. It is advisable to carry out roof thermal insulation and vapor barrier work simultaneously.
2. Choose high-quality vapor barrier and carry out professional installation.

TechnoNIKOL vapor barrier for walls:

Vapor barrier of walls is no less important: it is known that the largest heat losses constructions occur mainly through unprotected walls. Professional work on arranging a vapor barrier with TechnoNIKOL films will lead to the fact that the room will become constantly comfortable, and the warmth will remain inside. TechnoNIKOL vapor barrier for walls creates a strong barrier to their saturation with moisture during the diffusion process.

When organizing vapor barrier work, as a rule, a layer of material is chosen that has a fairly high diffusion resistance coefficient. Traditionally, building materials such as parchment paper and roofing felt are used; aluminum foil and polyethylene films. In each case, careful taping of the seams will be required.

Measures for vapor barrier of walls from the TechnoNIKOL company

A distinction is made between external and internal finishing with a vapor barrier layer. Before defining best option finishing, it is necessary to take into account the area of ​​the walls and the material used during their construction. If the budget allows, and the project is under development, then we recommend adding a veranda to your home, it will play the role of a necessary air cushion, preventing the leakage of warm air.

Such a project will reduce your vapor barrier costs to a minimum. It is much more difficult to carry out measures to vapor barrier the walls of concrete or brick buildings. Architectural structures made from these materials have high thermal conductivity and are “famous” for their high thermal output. External work related to vapor barrier of walls has three execution methods:

1. "sandwich panel" - wall+ thermal insulation material+ TechnoNIKOL vapor barrier + protective and decorative panel;
2. installation of insulation elements on the wall using a special vapor barrier adhesive composition;
3. A radically new direction in construction, where you can do without vapor barrier, is the construction of a ventilated facade.

The advantages of the latter method include: the ability to perform work all year round, insulation can be carried out in local, problem areas without disturbing the architectural appearance of the building.

Roofing Vapor Barrier TechnoNIKOL

To begin with, a few words about the requirements for the material used in roof insulation activities.

1. Insulation must be selected with high moisture resistance values ​​that do not decrease throughout its operation.
2. Comply with fire safety requirements,
3. Do not pose a threat to the health of residents, comply with environmental standards and do not emit toxic substances.

The Technoblock insulation fully meets these requirements, from the TechnoNIKOL company,which is based on . Most attention should be given to flat roofs, where heat loss is always high.

Things are somewhat easier with the device pitched roofs, they significantly reduce heat losses and requirements for roofing material they are noticeably softer. Another recommendation is to choose a heat insulator with the lowest shrinkage coefficient in order to avoid the occurrence of “cold bridges”.

Waterproofing or vapor barrier TechnoNIKOL?

One universal film, which, like magic, can protect the insulation throughout the entire building, in this moment On the market building materials, simply does not exist. The difference between the TechnoNIKOL hydro-windproof membrane and the film of the vapor barrier layer is significant. Let's clear this issue up once and for all.

TechnoNIKOL vapor barrier is installed on the inside of the building and is designed to protect the insulation from water vapor generated inside the room. Understanding how this works will help us understand the phrase “dew point”. Inside the wall, at the meeting point between the warm air from the room and the cold outside, dew falls, forming drops of water.

Accordingly, if this point is inside the heat-insulating material, then it gets wet. Especially actual problem it's getting cold, winter period. TechnoNIKOL vapor barrier serves as a vapor barrier and helps prevent moisture insulation, roof or wall structure.

The most problematic in this regard is considered to be a building built using frame-panel technology. Behind mandatory use We will name three main reasons for vapor barriers:

1. Durable construction for many years. Interior decoration TechnoNIKOL vapor barrier, promotes the removal of the “dew point” as close as possible to outer surface walls.
2. Mold won't go away! TechnoNIKOL vapor barrier prevents the occurrence of mold and fungi.
3. Comfortable living conditions and savings. Using vapor barrier materials, it is much easier to maintain the required level of comfort, as well as save electricity on heating and air conditioning.

So we’ve sorted out the vapor barrier, now let’s clarify what waterproofing is. If a vapor barrier protects the insulation from internal vapors, then waterproofing is designed to provide protection to the wall, rafter system, ground floor floors from penetration external moisture.

In addition, it serves as a barrier from snow, rain, wind, dew and other adverse weather conditions. If you are completely confused, we suggest you watch a short video instruction on working with TechnoNIKOL materials:

Vapor barrier TechnoNIKOL types and scope:

High quality polymer serves as the main resource for the production of vapor barrier building films. Stable vapor permeability values ​​are ensured by a multilayer structure, which also withstands significant loads thanks to high performance strength.

As we have repeatedly said, the main function of Technonikol vapor barrier films is to create a vapor barrier and protect the insulating material from internal water vapor that occurs in the premises. TechnoNIKOL vapor barrier will greatly reduce the processes of steam condensation in frame-panel fencing elements of the structure.

The negative effect of moisture on the thermal conductivity of a building structure is very obvious; the thermal insulation material is destroyed, especially during freeze-thaw cycles. A humid environment is beneficial for the proliferation of fungi, microbes, mold and other harmful microorganisms.

1. TechnoNIKOL vapor barrier for pitched roofs and walls

Used in conjunction with superdiffusion membranes. Vapor barrier has properties that allow partial diffusion of liquid vapor, which fully contributes to maintaining a favorable humidity regime inside frame building. This is enough budget material, the basis of which is polyethylene and parchment.

The film involved in joint use is TechnoNIKOL superdiffusion optima - it is a three-layer microporous material. Two layers are made of non-woven polypropylene; these layers serve as a frame for the internal “working” filling.

Working inner layer implements the diffusion of water vapor,but does not allow liquid leakage. The strength of the membrane is used in organizing the insulation of ventilated facades of high-rise buildings, as well as in sloping roofs. As a bonus, we note that the membrane is great for temporary protective coatings, as it can withstand sunlight and wind loads for a period of 4 months.

2. TechnoNIKOL reinforced vapor barrier

More reliable and durable material- three-layer membrane version. Reinforced vapor barrier film TechnoNIKOL, consists of several layers polymer material, which are soldered together with a reinforcing mesh.

This material has high bending, tensile and tearing strength. In addition, it lasts four times longer than conventional vapor barrier films. TechnoNIKOL vapor barrier is used in insulation measures frame structures in low-rise construction. Due to its increased strength properties, it is often used in construction flat roofs.

3. TechnoNIKOL vapor barrier for flat roofs

Characteristics vapor barrier film, give us the right to confidently declare its high elastic properties combined with increased strength. Even from the name it is clear that it was developed specifically for vapor barrier purposes in flat roof insulation systems.

4. Universal vapor barrier film

TechnoNIKOL engineers managed to create a universal product that simultaneously has high strength characteristics both horizontally and vertical positions. Due to the versatility of this TechnoNIKOL vapor barrier, its use in insulating pitched and flat roofs is allowed.

Probably, based on the results of our review of TechnoNIKOL vapor barrier, a reasonable question may arise: is it possible to do without vapor barrier at all? The answer lies on the surface if your house is built from - for example log house, then n There is no need for vapor barrier measures.

If you are building frame method with the abundant use of materials with different diffusion resistance coefficients, then work related to vapor barrier is vital.

Concluding our short review of “TechnoNIKOL vapor barrier”, we would like to note that despite the fact that this modern material, meeting all the requirements for vapor barrier materials, we still advise you to contact professionals for the final calculation of the thermal protection device.

High quality with an optimal pricing policy makes numerous products from TM TechnoNIKOL constantly in demand on the market of the CIS countries. All you have to do is choose a suitable vapor barrier based on the characteristics of the insulated surface.

Rapidly growing sales figures indicate the enormous popularity of the membrane. TechnoNIKOL vapor barrier becomes an irreplaceable product when it comes to high-quality insulation your house. Compliant with European Union standards and possessing a Russian Federation certificate, TechnoNIKOL vapor barrier is widely used in low-rise residential and industrial construction.

Before starting installation activities, carefully read the installation instructions, instructions are included in the kit. In a packaging roll, any vapor barrier TechnoNIKOL,contains an attached brochure - “Installation Guide”, which will help you install the film right side without making mistakes.

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 products for TechnoNIKOL insulation, meeting construction standards in terms of fire safety and harmlessness and differing high quality and accessibility. 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. WITH outside it is marked - a gray line 12 cm from the edge, confirming the presence of vapor-tight 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.

Basic specifications vapor barriers TechnoNIKOL:

• vapor permeability (value that controls steam transmission): 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 highest 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 purchased to temporarily replace the roof during the repair period, but it will not lose its useful properties);
• maximum operating temperature: 70 °C.

Types of vapor barrier

The products are represented by three brands:

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

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

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

Benefits of use

The advantages of TechnoNIKOL vapor barrier include:

1. Easy installation of roll film.

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

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

5. Availability. Prices for vapor barriers are average; you can simply buy rolls at any construction supermarket or order them online; there are no problems with 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 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

Reinforced vapor barrier produced by TechnoNIKOL is made of polyethylene high density and has 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. Doesn't highlight 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 penetration of water vapor from interior space 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;
• provides the necessary temperature and humidity balance in the room;
• durability;
• resistant to biological and chemical influences.

Packaging and storage

The roll is sold in plastic packaging with factory markings. If necessary, it is possible to supply products on pallets. Storage must be carried out in a closed warehouse.

High-quality vapor barrier from the vapor barrier film manufacturer TechnoNIKOL will help protect the structure from atmospheric influences and extend the service life of the entire building. You can order required amount material on our website by filling out simple form applications..

• 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. In any premises, especially in residential ones, it accumulates incredibly a large number of moisture. When the outside temperature drops, due to a significant difference in the outside and internal temperature 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. Sturdy material not only convenient to use, but better resistant to 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 stabilizers ultraviolet radiation, 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.

  Determine harmfulness vapor barrier material simple enough. If you roll out a roll in a closed warm room, then the low-quality film will begin to highlight 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 very different high level strength and UV resistance. 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. It's 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 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 slopes - suitable 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 series reinforced layers, more durable. Due to large number microholes, 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, covered on one side polymer film. The exceptional strength of the material allows it to be used as a temporary roofing, which 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.
