Foil film for a warm floor. Foil vaporizoation will save your money what is better vaporizolation or foil

Materials used in the construction of roofs and arrangement of premises with non-standard temperature and humidity operating regimen are executed by manufacturers by special properties. They not only freely oppose the attacks of a rich fervor of hot air, but also create the effect of the "thermos", due to which the energy consumption for heating is repeatedly reduced.

Such specific products include foil vaporizolation, the installation of which allows to solve the mass of important tasks in the construction of building structures.

Foil materials used in the vapor barrier device are complex products with a layered structure. The base is performed from the polypropylene web, lavsan, fiberglass and similar options resistant to gap, as well as to chemical and biological aggression.

The use of a durable woven or nonwoven polymer base allows you to create a reliable base for fragile by the nature of the metal foil. At the same time it was possible to ensure the flexibility convenient in the installation. The composition of thermoplasts used in the manufacture of thermoplastics excludes the possibility of rotting and resettlement of fungal colonies.

From the work side, vapor barrier materials of this category are duplicated with a metallized film. Thanks to the method of applying a foil coating, all positive qualities of both the polymer base and aluminum foil, which "perfectly" copes with the execution of three very significant functions, is:

  • Isolation from steam and precipitation. Fungalized materials perfectly protect the insulation of the roofing pie or the wall insulation system from the penetration of the steam coming from the inside of the hoody house, and from atmospheric water seeking to penetrate the outside.
  • Reflection of thermal radiation. The metallized coating serves as a reflector, interrupting heat waves outside the heated room and redirecting stopped heat in the opposite direction.
  • Wind protection and UV. Steam barrier films with foil play the role of a resistant barrier from the wind, seeking to bring warmth of cotton thermal insulation. They mounted outside the work side of them in the summer heat reflect from the attic roof of the sun's rays.

The use of vapor barrier with foil allows you to safely save on the payment for heating and less frequently include air conditioning.

Scope and methods of application

The structure and properties of foil vapor insulation materials significantly expanded the scope of application. These materials are used in insulated roofs, in our latitudes most often installed on the inside of the roofing pie, in the south are mounted over the insulation. In homes with an uncomplicated attic, foil defense is mounted in combination with waterproofing.

In addition to the traditional purpose of protection against a pair of ceiling floors and spaces of residential attic, they are used as a substrate for all types of flooring and warm floors, as well as in insulated framework wall structures. They are installed as a screen reflecting thermal flows from heating devices and heating units.

In order for foil materials to perform a reflex function, it is important to correctly arrange the system. A non-ventilated air gap 2 - 3 cm should be formed between the inner shearing of the attic, the walls, the ceiling of the steam and metallized coating.

In the case of a flat or attic roof as a heat transfer screen, a standard ventilated clearance of 3-4 cm is left between the unfolded outward-out-based plated coating and the roof. There are no target in maintaining thermal energy. All that was reflected from the foil can be freely exitted into the atmosphere together with condensate and penetrated the heat insulation by steam.

The gaps needed to ensure ventilation and to comply with the distance between different parts of the roofing pie materials are formed by mounting the crate of the bar or metal profile. Installing reshetins in accordance with the type of roofing, slope slope and the calculated load on the rafter design.

Advantages of using isolation with foil

The indisputable insulating priorities of materials in which the water-repellent material is combined with foil, are complemented by an impressive list of convincing advantages, this is:

  • Lightness. The installation of vaporizolation protection at all does not affect the weight of the structure as a whole, it does not force measures to strengthen the foundation.
  • Minimum thickness. Laying the vapor insulating layer is completely not reflected on the thickness of the roofing pie. When using materials with anti-condensate properties there is no need for a remote gap device between vaporizolation and trim.
  • Flexibility. The device of the vapor barrier is easily carried out, there are no problems even when laying in comprehensive forms. Without problems, convex and concave angles are enveloped, rounded surfaces.
  • Manufacturability. Rolled materials are easily designed by conventional sharp scissors or a construction knife.
  • Environmental Safety. In the manufacture of vapor barrier films, raw materials are used that do not represent the threats to the environment and the owners of the structured structures.

The variants of vapor barrier produced in an abundant variant with a foil absorption absorb, differ in zero porosity. Long-term operation of them in wet premises does not threaten by reinforcing materials. An important advantage is multifunctionality, due to which several adjacent structures can be protected by the same film by creating a solid hermetic barrier.

Foil Protection Installation Technology

We will analyze the most common technological options for using vapor insulation materials with foil. In the format of our site to the situation under consideration, we will take the arrangement of a warm attic and a cold attic. In the first case, the insulation system is installed on the skates, in the second - on the ceiling overlap.

Since the main purpose of vapor insulation films is to protect the insulation, then their place in the system is determined by the position of this component of the roofing cake. Those. In mansard structures, vapor barrier is installed on the rocks, in the houses with a cold attic it is placed on the attic overlap on top or attach from the bottom under the ceiling sheel.

For a literate device of a vapor barrier, adhere to the generally accepted rules:

  • Parosolation of the skates must be a solid moisture protection carpet, absolutely excluding moisture penetration or eliminating the likelihood of maximum degree. For this, the roll of the roll material is hermetically combined with scotch.
  • The strips of vapor barrier material are strictly horizontal. The starting cloth is attached to the skate run, the following is superimposed on it so that the edge of the cloud located below overlap the edge of the already installed strip from the side of the premises.
  • A vapor insulation material on a wooden overlap from the side of the attic steam stripes with an occasion on the walls and vertical coatings of 15-20 cm. In the end, something like a pallet with sides should turn out.
  • The material on the equipment is rolled up as the roll was formed by the manufacturer. The side of the stacking is mandatory indicated on vapor barrier protection, it is impossible to change it at its own discretion.
  • The fastening of the material on the pitched roofs is made from the inside of the rafter feet by the stapler, if necessary by the rails. If fixation assumes the use of a bar, then a controlled control is installed on top of it.
  • In systems with open rafters, vaporizolation is placed on the outer ribs of the rainfall legs, then the rigid slab insulation is installed. The material is fixed by the stapler.
  • In insulation schemes with extrusion polystyrene foam with the arrangement of residential rooms with a traditional operating mode, i.e. Without steaming and exposure to high temperatures, the vapor insulation layer is not allowed to use.

To arrange overlapping from the ceiling, it is desirable to pick up self-adhesive materials. In the insulation systems of adhesive overlaps with a falling insulation, for example, with a clay of a strip of vaporizolation protection, not to glue the scotch, because They will be harvested.

With the arrangement of attic floors of houses with cold attics, a vapor insulation carpet is constructed overlaid, and the waterproofing is put on the roofs. In this scheme, the insulation is washed by air flows created by natural ventilation, because any insulating layer above it will only interfere with the removal of moisture.

And further. When using foil isolation, it is important to select accessories of the same company as the material itself. There are, of course, universal scotchs capable of connecting any kind of material, but because Systems with increased tightness requirements are arranged from the isolation with the foil, then the options for bonding tapes are better not to experiment.


Overview of the leading foil options

In order to choose a suitable vapor barrier film for the arrangement of attic or ceiling overlap, you need to familiarize yourself with the collaborates and proven in practice by products of different firms.

Energy Saving Film Delta®-Reflex

Products of the Delta brand perfectly showed themselves in the construction of the roofs and earned an impeccable reputation in the roofer environment. Located from the working side, the reflex coating of the material is created by spraying. A polyester film is applied over the spraying, protecting the aluminum layer from damage and squeezing. The reflection coefficient is 50%.

The film of this brand does not lose flexibility at minus temperatures, can be used in a steam protection device both outside the house and from the inside. Made to use in all species of wet rooms. On the edge of the canvases of a similar film, but with a supplement in marking the word Plus, a self-adhesive tape is laid, relieves the facilitating work of installers.

Reflective Material Izospan FD

More humane in price ratio, but less resistant to the realities of roofing adversity Material with marking The ISOSPAP FD is a two-layer composition of polypropylene web with an aluminum coating applied to it.

I am inferior to the previous representative according to strength indicators, but is ahead of energy-saving characteristics: the coefficient determining the thermal reflection is at least 90%. Attracts accessible price and stable availability in the trading network. In the technical passport, the temperature range is indicated from -60º to + 80º.

Superpper version of the Armofol® type A

Folgized vapor barrier with the specified logo is made on the basis of fiberglass mesh. The scope of use is no different from the above types, but the product has significantly expanded the temperature operating range. The material is capable of perfectly serve at a temperature of up to - 60º, which is 20º ahead of the delta. The limit in the positive segment is + 150º, which is already more than 70 confident units.

Along with the opponent, Armofol can also be applied in new construction, and in carrying out restoration work when repairing roofing, basement and basement structures, paired Russian baths, pools, bathrooms, saunas. The value of the thermal reflection coefficient reaches 90 - 97%.


Video about the features of foil isolation

Once again about the breadth of use of insulating films with foil:

Information on the use of a foil vapor insulation film in construction is needed not only to independent masters. It will help competently check the work of hired roofers. Properly laid material guarantees the long-term operation of the favorite furniture.

Protection against water and moisture is an important component of any construction. The use of wooden materials obliges to think about vapor barrier, because steam can cause mold and fungus. Couple insulation is also successfully used when mounting the roof, when insulating the living room from the basement.

Features

The question of vaporizolation arose with the advent of the mineral insulation. It may sometimes seem that the air in the room is very dry, but in fact it turns out that the insulation is a wet from the existing moisture and gradually collapses. Moisture appears due to the difference in temperatures. In winter, the side of the wall, overlooking the street, is freezing, and the side located in the room warms up with heating.

With a large temperature difference, the "dew point" is formed. In this case, the insulation accumulates condensate. It has been established that with an increase in the amount of moisture in thermal insulation, 5% heat insulation properties are reduced by 50%. Interior partitions do not tolerate temperature drops, so steam barrier is superfluous.

When building a house, pay attention to what the materials you build and what are planning to insulate the house. The vapor insulation layer is a waste of money, if you use foam, penplex, or at all, we decided to do without heat insulation, using a foam block or brick.

One of the reasons for vapor insulation in the house is the savings. With the right calculations, the costs of additional materials for the insulation of the building pays off by further saving on heating resources. Modern material Mineral wool - insulation, losing its properties during wetting. It's easier to spend once and save all the subsequent time than to constantly change the thermal insulation.

Parosolation in its intended purpose is divided into:

  • Stenaya. To prevent steam to the insulation on one side and the output of the steam outside when it gets on the other.
  • For inter-storey overlap. Prevents condensate accumulation "bottom up".
  • For vaporizolation of the floor.If the floor plate of the first floor is located directly above the soil, in addition to thermal insulation, water protection is needed. Waterproofing is laid below, and vaporizoation from above. The same method is suitable for any premises with high humidity.
  • To protect the roof. The insulation of the roof from the steam is necessary only if there is heated attic or a attic. All pairs go up, thereby getting into the thermal insulation materials of the roof, and again forming condensate.

Steam barolation differs from waterproofing also in that the waterproofing materials are harvested on the surface, so they are ideal for places where drops can be formed, for example, roofing or base.

Regulatory requirements

Any construction is based on gostas and lights. Rolled vapor insulation material also obeys standards. GOST 30547-97 says that in the classification "By appointment", vaporizolation belongs precisely to rolled roofing and waterproofing materials.

The main characteristics of the material for its application according to GOST:

  • the canvas must be solid, without mechanical damage;
  • each roll must be marked, in the absence of marking it is not recommended to use it.

The document on a specific type of material should be indicated:

  • a combustion group - calculated for vapor barrier with a thickness of more than 0.2 cm;
  • flame distribution group- for vapor insulation materials when using them for the device of a single-layer or upper layer of multilayer roofing carpet;
  • group of flammability - for vapor insulation materials with a thickness of more than 0.2 cm.

The combustion and combustion groups of vaporizolation material are determined according to GOST 30244, the flame proliferation groups according to GOST 30444, the flame groups - according to GOST 30402. For rolled vapor barrier materials with a thickness of less than 0.2 cm, the fire danger indicators are allowed not to determine. Store material is necessary in places remote from the sources of moisture and the sun.

Despite the fact that the purpose of the vapor barrier material is in isolated from steam, storing it next to the sources of moisture can worsen its characteristics, and during application the material will not be so effective.

Requirements for work:

  • According to SNIP III-in 12-69, the outdoor insulation works can be carried out only in the absence of atmospheric precipitation and at an outdoor temperature not lower than 5 C.
  • Parosolation coatings should be arranged in compliance with the rules for the production of waterproofing work.
  • When the vapor insulation of horizontal surfaces is adjusted to the walls, it is necessary by 10-15 cm to start the vertical surface, so that the vapor barrier is connected to the waterproofing layer and prevents moisturizing the thermal insulating layer from the walls of the walls.

According to the safety technique, it is necessary to choose a film of vapor barrier, which is non-combustible.

How is it arranged?

The main function of the Parobarmer is to prevent the penetration of steam and moisture on both sides. The barrier is so sealed that it does not allow to leak into the moistened air through the construction systems. By itself, a steam-insulating film is a rolled material that prevents moisture penetration and steam into thermal insulation and other materials related to the construction. The principle of work is as follows:

  • Couples must come across an obstacle in the form of isolation.
  • Under ideal conditions, the film should push the couple, not allowing it to settle on the material.
  • We know that there are no ideal conditions. Molecules can leak through microcracks, slots, joints. All this is displayed back due to ventilation functions.
  • In order for the film properties to be used, you need to lay a film under the insulation.
  • During construction in any technical documentation, the vapor permeability of the material is taken into account. It is indicated as mg / m2 per day.

For completeness of the effect, the following material laying scheme is used - Steamer-insulation-waterproofing. Thus, those evaporation, which still penetrated through the parobarar, fall into the insulation, and he, in turn, is trying to push the molecules, after which they fall on the waterproofing layer, which displays the remains of the steam in the pre-left ventilation gap.

Application area

The parobarar can be applied in many areas. Recall the greenhouse known since childhood. The film does not allow a couple to go out. Most often in the construction of a parobarrier isolate a roof, plans for attic and warm attic. The device in the outer walls of the house allows you to save heat. Parosolation on the floor of the ground floor prevents evaporation from the soil.

Below are represented the main areas of vapor insulation:

  • Warming of premises. This is especially important if thermal insulation is performed from materials, the basis of which is wata. Glasswater and mineral wool allow the walls to "breathe", but absorb moisture. And the more moisture in the insulation, the faster it is destroyed. And the house want to build immediately and "on the century".
  • Walls from the "carcass". "Pie "Walls consists of many different layers. Such walls are called frame, but due to multi-layered, construction does not cost without vapor insulation materials.
  • Exterior walls and ventilated facade.The parobararier is excellent wind protection, air flow can not be actively circulated, so the load on the facade is reduced.

  • Ceiling. When building a house, it is important to isolate the floors from each other. The ceiling vaporizolation allows longer to maintain the strength of the overlaps, does not allow the formation of fungus.
  • Floor. Flooring is often subjected to temperature drops regardless of whether the heated floor or not, is on the first or last floor. Most often, the floor covering is made of wood. Laminate laying conditions are an ideal reason, so it is most often aligned with screeds or mixtures. This appears excessive moisture, which without a vaporizolation layer can harm the boards of laminate.
  • Balcony. The reasons for the need for the device of the vapor barrier layer on the insulated balcony are exactly the same as during the insulation of the walls - prevent the formation of condensate in the insulation.

Operating principle

The principle of action of rolled insulation from the pair outside and is different inside the building. Frame walls are inspected from the inside, so the parobarrier is laid from the inside. On the ground floors and in the basement, the vapor insulation layer is performed outside. In the pools, vaporizolation is needed on both sides, and its laying technology is similar to work on the basement.

To achieve the desired effect, when installing the film should not be gaps, so the material is stacked by Vangest. If you are afraid of insufficient laying density, you can glue the edges for the formation of a single canvase.

If the parobararier "works", steam meets the obstacle on the way and remains indoors, while not cooled and remains in a gaseous state.

Views

Previously, except Ruberoid, there was no other vapor barrier material. Now the choice is varied. All materials can be divided into several groups:

  • Ordinary film.Standard insulation is made by the Minvata, and in this case the polyethylene film is needed so that when the temperature difference on the warmed walls and the roof is not formed condensate. The best option from all on the market presented is perforated polyethylene.
  • Film with aluminum foil.Foil film has a higher barrier, due to which it reflects and returns some stake in the room. Such a film is ideal for use in the bathroom, sauna, bath or pool, i.e. for any room with elevated levels of humidity, steam, temperature.

  • As a vapor barrier, you can also use modern material, called kraft paper. Such a pair-protective insulation has a polymer coating that works due to its emergency sustainability to all types of exposure from external factors.
  • Mastic- Another variant of vaporizolation. The consistency during freezing allows you to achieve the necessary steam-proof effect.
  • Membrane film. Such a film has the effect of limited vapor permeability, which allows you to control the removal of excess moisture content. In addition to the standard membrane film, there is a membrane film with variable vapor permeability for wet and dry state. The bandwidth of the material increases with increasing humidity.

A group of membrane films can also be divided into several subgroups. So, allocate the following roofing membrane films:

  • Perforated. It is a reinforced film or a sensitive tissue. Couple passes through holes in the material, so vapor permeability is very low. For this reason, the membrane is used only for underlining waterproofing of an inclined radiated roof. During the fall of water or a sharp change in temperature loses its properties.
  • Porous. Couple passes through a large amount of inter-ramp pores. The pair-protective level of the material may be different and depends on the size of the pores and the degree of hydrophilicity of the walls. You can say for sure that the level of steadility will be worse in the fibrous membrane. It is undesirable to use it in conditions of high dusting, for example, in city houses located at the roads. In dry or warm weather, dust through the gap can dump on the membrane material and close the pores.

  • Three-layer superdiffusion membranes.Produced from several different layers and having no holes in which dust or moisture can enter, the membrane has an obvious advantage over porous. The material does not lose high vapor permeability in the dusty environment, but it is impossible not to say about excellent windproof ability.
  • Two-layer film membranes.Less spending option. They do not provide one of the protective layers, which significantly worsens their reliability. Thin waterproofing film cannot protect the coating from more or less serious damage.

How to choose?

When choosing a vapor insulating barrier, you need to be guided by the volume of the warmed surface and the place of application of the barrier. The difference in the use of materials for the floor, walls, roofing and overlap is significant. To simplify the selection of the material, you need to analyze each model that the criteria presented below the list of criteria below.

Parp permeability

Parry permeability is measured in g / m2 per day. The lower the number is indicated, the higher the quality of the material. For the insulation of the dwelling, it should not exceed 1 g / m2 per day. Anti-condensate polypropylene films with nonwoven adsorbing layers and diffuse "breathable" vapor insulation membranes have the best indicators of vapor permeability.

There is another indicator that measures vapor permeability - SD, which demonstrates how the film resistance refers to the resistance of the air layer of a certain thickness. For example, if SD \u003d 0.02 m, this means that the vapor insulation material has a pair resistance as a 2-centimeter layer of air.

It is necessary to choose a material with a low value of this indicator.

Durability

The durability of the film depends on its quality, density and thickness, as far as it is subject to mechanical damage. The lower the price of the material, the lower its strength. There are films weighing 60-270 g / m2. Many reviews say that using the usual 180 g / m2 polyethylene, you will not be mistaken in terms of price and quality ratio.

Labor intensity

Different types of film are mounted in different ways. Before buying, it is necessary to determine the installation and those who will produce it - a qualified specialist or you are your own hands. Most convenient in the plan of self-installation film "Ondutis B (R70) Smart"with an integrated mounting strip, the price of which for a roll of 75 m2 is approximately 1400 rubles.

Cost

Last selection criterion. You can refer to the low price category, and select a simple polyethylene film, you can choose an expensive material or a medium price category. It is impossible to say that the most expensive vaporizolation is the most reliable, and the cheapest is the worst. Also the price depends on the width and length of the roll. Many do not pay attention, choosing a film cheaper than the most condemnant for an additional purchase of material.

Also, when calculating the material for use in the floors, it is necessary to remember that the vapor insulation material will be a kind of "blanket" for the insulation, and its ends should go beyond the Ministry of Way. Also, when the ceiling thermal insulation device is wrapped in a parobararier and firmly, without gaps, attach to lags. From this material consumption increases.

Most often advised to take the film of the last generation ondutis, which is considered better than the rest of their predecessors.

The choice of vapor barrier manufacturers is treated today. In addition to conventional polyethylene films, there are films reflecting. Their dignity is that having a foil layer in its composition, they retain heat. Such material is often applied in cases where it is impossible to achieve sufficient insulation with the help of minvati. Overview of the main brands, aluminum foils presented in the market:

  • "Folgoplast FB" (Company NPP "StroyTermizolation", St. Petersburg);
  • "Megazole S" ("Mega", St. Petersburg);
  • "Foil heat insol on kraft paper" ("Heat-ins", Yekaterinburg).

Kraft is a treated wood, which is the most efficient insulation material. When used together with reflective foil, it is possible to prevent the passage of thermal radiation and the adherence of such a material for insulation. Foil and craft paper manufacturers with polyethylene or lavsan layers included:

  • "Alukraft" (CJSC "PlastEks", St. Petersburg);
  • "Izospan FB" (LLC "Hex", Tver Region, TM "Izospan").

If you decide to perform vapor barrier with your own hands, you need to know the subtleties of the device and installation. Wall device:

  • It is necessary to determine the type of fastening to the walls - it depends on the destination of the location. In non-residential premises, one-sided fixation of the material is possible. Although most often right on the packaging of the material indicate the necessary fastening type.
  • If it is not construction, but repair work, then the complete dismantling of the design to the wall is performed.
  • Perform work in the warm season in the absence of rains.
  • For fastening the material where there is no fastening tape, a construction stapler is used.
  • The tension should be tightly keeping the insulation at the wall.

Fastening to the ceiling:

  • Do not try to perform insulation and steam barrier ceiling alone. For these works, at least two people are needed.
  • Start work only when the ceiling is dismantled and only the base of the lag remains.
  • To begin with, fasten the film in several places, and after, checking its correct location, secure around the perimeter.
  • On the bottom, the film is fixed with wooden slats. This is necessary, regardless of how the coating is in the end, it will be in the end.
  • With random damage to the membrane, it is necessary to make a patch with large batteries on the sides. Blind a piece need "from the inside", and not on top of the film. To do this, the patch must be inserted into the resulting hole, straighten and glue the allowance.

Steam barrier of frame walls:

  • It is important to comply with the correct imposition. Frequent error - Laying the film is not the same side. Also, the most famous errors include the fastening of the film not on the side of the wall. With frame walls, the barrier must be attached exclusively indoors, but not outside.
  • It is necessary to choose the way to fastener. There are two of them: the film is fastened to the wall frame, and the facing material is mounted on top, or the film is attached to the wall frame, then the rails are additionally mounted, and only then the facing. The first option is used only when working with expensive and high-quality materials or with premises non-residential or used not all year round. The option of adjustment with ventilation is more practical and durable.

Parosolation baths:

  • since steam during circulation in the room rushes up, it is necessary to embroider the clay boards and wait for it in front of the heat insulation device and wait for its complete drying;
  • materials for the arrangement of the walls of the baths are purchased only after a well-thought-out insulation plan, a hydro and parobarier;
  • do not use the rubberoid to isolation of the steam;
  • for the bath, it is better to choose an ordinary polyethylene or foil, and to arrange the changing room and the washer - kraft paper.

Floor vaporizion:

  • vaporizolation must be laid with a smooth side to the insulation, and protected to the source of steam penetration;
  • optimal for sex, reflective films returning heat into the house are considered;
  • when the device on the first floors and bases, the floor is protected by a layer of waterproofing, and from top to roll vapor insulation materials.

Roof vaporizolation:

  • when installing vaporizolation, you need a device of ventilation gaps, but when using any kind of membrane, it is possible to refuse without prejudice to the quality of insulation;
  • in the case of the roof, vaporizolation is laid on the enshrined layer of the insulation;
  • the size of the alternation is from 10 cm;
  • there is no difference, vertically or horizontally you fasten the insulation.

Remember that when the device isolation, the roll material must be a single cloth fixed. Do not spare the material on the allen and attachments.Follow the tension of the film. Insufficient tension will lead to beds, and excessive - to damage to the web. And in that, and in the case of the necessary characteristics of the material will decrease or disappear. Remember about ventilation. Do not waste time and money for vapor barrier in a log house - unlike other materials, this is not necessary.

Always insulate the first floor floor. Do not confuse the sides of the insulation - the internal is considered to be the one that adds to the roll face. All surfaces during installation must be dry. When purchasing a roll material, check the package. More profitable to buy material includedwhere the fastening tape is already underway, the necessary rails and other details for fastener is this model. If you still doubt the self-selection and installation, trust the professionals.

With the rise in the cost of energy, there is a need to make heat loss through the walls / floor / ceiling minimal. To solve this problem, lay the layer (its thickness depends on the purpose of the room, the climatic conditions and characteristics of the selected type of material). But the other problem occurs: with the inevitable temperature drop between the outer and internal surfaces, condensate is formed. If it is formed in the layer of the insulation, it entails a decrease in its characteristics. It was established that with an increase in the humidity of thermal insulation by 5%, the heat insulating properties decrease by 50%. After drying, the properties are restored partly, thermal insulation gradually becomes worse, the loss of heat is more significant. Since the room is almost always the humidity above (and in the bath, so more), then the couple strive to get outward, along the way "Shot" in the insulation. To prevent the penetration of the steam and laid steam barrier from the room.

Typically, vaporizolation is laid by the room. This is due to the fact that the humidity is usually inside the room. This is especially characteristic of kitchens, bathrooms, as well as baths and saunas. For baths or saunas constructed by their wood, the penetration of moisture in the wood is fraught also by the formation of mold and gradual destruction of the tree. This problem is especially relevant for Russian baths with their high levels of humidity.

In traditional baths of rounded logs without additional thermal insulation, the removal of vapors, moisture regulation and drying room occurs due to natural processes. Even with perfectly fitted logs and regular interventic compounds, the removal of vapors and the flow of fresh air occurs due to the micropores of the wood, small slots in the logs. That is how our ancestors were soared: the bathroom was heated for a long time - six to eight hours, they did not hurry anywhere and did not save firewood.

It is also necessary that the bath is ready to maximize, for an hour, energy costs should be minimal. This is achieved at the expense of a multilayer "cake" from various materials to preserve heat and steam. A layer of vaporizolation in such a "sandwich" is required, otherwise all the "layers" will have to change in a year or two, and the wood for a long time and persistently "treated" from mold and fungi.

Waterproofing and vaporizolation: What is the difference?

The main difference in waterproofing from vaporizolation is in the vapor permeability of materials. Waterproofing does not let moisture, but collects it on the surface. Because this type of materials are laid in those places where moisture falls in the form of droplets, for example, under the roof flooring. Condensate with corrugated waste in the form of water droplets falls on the waterproofing, flows through it and is outputting outside the roof (because the edges of the waterproofing are wrapped in the form of an envelope).

The task of vaporizoation is different: it should not allow the penetration of water vapor inside the insulation. Since the couples are more with a warmer side, then the membranes or films are more often with the "warm" side. If we talk about the roof, then the materials of vaporizolation are put on the side of the attic room, if we talk about steam barrier to the walls of the steam or other places of the bath, then there are membranes / films behind the decorative trim.

Summing up: Waterproofing does not conduct water (but can carry out steam, releasing the one that penetrates into the insulation), vaporizolation does not miss steam.

What is the difference between vapor barrier from waterproofing, is described in detail in the video.


In order to minimize damage, it is desirable to use wooden planks that press the film to the guides, and already in the bar to score brackets / nails. Similarly, it can be mounted and membranes. They are not so torn as films from polyethylene or polypropylene, it is easier to work with them.


Fastening vaporizolation

Roll of rolled materials laid one on another fromthe adhesive of at least 10-15 cm, sinking the jokes with a sticky ribbon. You can use a specialized, foil or conventional sticky tape.


Foil tape is be sure to use on the joints of foil materials, otherwise most of their efficiency is lost. When smoking the joints of other materials, manufacturers recommend using their own tapes, but what their differences and advantages are not explained.

Please note that when installing the pair barlasting can not be stretched: they have a stretch / compressive property when temperatures change. To avoid breaks during tension, you need to leave a small stock. Normal is considered to be the "provis" of the web during installation by 1-2 cm. Especially this is true when laying vapor barrier to the roof or in an unheated room.

When installing vaporizolation in places with a complex relief (protrusions, angles, etc.), adjacent surfaces are desirable to sneak tape: perfect tightness in such places it is difficult to achieve, and this is the basic condition for the effectiveness of protection. Because any auxiliary funds will be alike. Clear Scotch and the edges of vapor barrier around the perimeter of door and window openings to ensure tightness. In general, tightness is the basis of high-quality vaporizolation of the bath, roof or any other room. Therefore, when carrying out work, pay a maximum of attention to this aspect.

In our climate, when the winter is frosting the whole country for almost 6 months a year, we need to look for ways to preserve heat. And even for comfort and comfort, it is necessary to ensure steam barrier to the roof, foundation, floor. And with all this successfully copes foil polyethylene film, which is capable of not only to keep heat in the house, but also not to pass moisture from the inside.

However, foil polyethylene film is used not only as a finishing material - it is also part of the packaging for food. Remember how often do you buy juices and milk in tetrapacks, raw materials and cottage cheese in bright packaging? But the reverse side of this package - foil!

What is the foil polyethylene film?

This is a two-layer material, one of the sides of which is a polyethylene film (or film from the foamed polypropylene), and the other - aluminum spraying. Aluminum spraying has special polymer additives in its composition, which provide resistance to mechanical effects, that is, protects this metallized layer of scratches, chips, deformations.

Another plus is resistance to the effects of aggressive media. Acid, alkali will not harm when hitting a foil layer. This applies to the material that is used in construction work as a warming and steamproof finishing material.

If we are talking about packaging for food products, then the main difference is the retention of moisture in the product. Plus, the foil perfectly retains the optimal temperature regime inside the package, not giving the product to spoil ahead of time.

Where can one buy?

If you want to get a really high-quality material for packaging or decoration, then the company Ava Love will be your reliable partner. Affordable prices, delivery efficiency and the possibility of ordering in an unlimited quantity - this is what attracts regular customer customers.

Foil film is a universal polymeric material. It is used in vapor insulation purposes in industrial and civil construction. For advice, contact the company. Building materials can be represented in different versions, colors and shades, with holographic coating.

Why do you need a foil film?

The material is necessary for thermal insulation, in cases of a large temperature difference outside and inside the objects. Suitable for vaporizolation of all surfaces, reliably holds moisture.

The foil vapor barrier film has auxiliary layer, which does not allow condensate to penetrate into the layers of the insulation, protects it. A high-quality film reduces heat loss, enhances the insulating effect at the construction object. The material contributes to the direction of thermal energy in the right place.

Varieties of material

Usually, the foil insulation film comes in the form of rolls or reservoirs having different size and density. The composition includes the basis and reflective layer of the film. In various modifications, layers may be several.

Foil film is divided into three types:

  • With aluminum spraying;
  • With foil layer;
  • With aluminum foil.

According to the composition of the material happens:

  • Foam polyethylene, universal insulator (foil can be with one or both of both sides);
  • Foil polystyrene foam insulation;
  • Foil foils from foams;
  • With basalt cotton;
  • Folgized insulation with self-adhesive surface.

Properties of material

The texture of the material is solid and smooth, in the course of work guarantees the absence of irregularities, seams, cracks. Fungalized vapor insulation film is suitable for finishing houses, baths, arbors, for a warm floor, walls, ventilation systems, roofs, refrigerators. Film can be given any shape, as it contains a flexible solid structure plus aluminum spraying of a foil view.

Favorable qualities of a foil film:

  • Easily attached to the wall, other surfaces, is easily installed;
  • Withstands the temperature from -40 ° C to + 100 ° C;
  • It is made of environmentally friendly material, does not have the harmful effect on the human body at any temperatures;
