Installation of vaporizolation is required during construction residential houses: The membrane protects the insulation from the vapors emanating from the room inside the underpants; On the other hand, a vapor barrier film prevents condensate condensate. Improper installation of the membrane (not the side) is fraught with the accumulation of excessive number of vapors indoors, as well as uncontrolled moisture access directly under the roof. The insulation is gradually soaked with water and will cease to perform its functions, and the material of the crate and roofing is subjected to intensive destruction.
Special materials for vapor isolation are available in the form of single-layer films, foamed polyethylene with metallized coating and two-layer membranes. Their installation has some differences, because of what to deal with which side to fix vaporizolation, it is not easy:
Given the variety of vapor insulation materials in the construction market, it is difficult to compile an exhaustive guide to their laying. Detailed information is usually contained in the instructions attached by manufacturers. But still, there are two more general rules:
For scope roof There is a certain sequence according to which a high-quality parobarrier is installed. It is mounted after laying insulation, on the surface of which there should be no defects. The bars for the crate are treated with anti-grapple compounds, after which they prepare a pre-calculated amount of film (covered area +15%) and the following:
On the rafters, between which thermal insulation plates are laid, fill the bottom of the crate of two boards. Stick a strip of a special tape with two adhesive parties. Remove the roll on the canvas of the corresponding length. Then, starting from the bottom of the crate, horizontally lay the membrane with marking up on the insulation, slightly pulling the cloth.
Placeing the membrane, it is necessary to monitor the integrity of its surface. In the case of detection of defects on the fixed area, the damaged web should be replaced or (if there is a small damage) to stack it with a mounting ribbon.
Mounting vaporizolation on the walls only if used mineral insulation and / or their outer surface is on the street. It is especially important how to properly install a vapor barrier film on the walls. To do this, use the above accessories, do the following:
During construction country house or private bath important stage is thermal insulation different surfaces. In addition, the insulation itself needs high-quality and reliable vapor insulation protection. In order to prevent the negative impact of external factors and the formation of condensate on the thermal insulator, any homeowner must have a general idea of \u200b\u200bhow to properly lay vaporizolation to ensure a long service life of the whole structure.
The most patched on its operational characteristics are breathing multilayer membranes, which are designed to create reliable vapor barrier protection.
They consist of three layers, each of which performs important function. The first layer warns the penetration of steam into the insulation, the second ensures the necessary strength of the base, the third protects against moisture from the outside.
Each individual layer has the necessary perforation for a good air exchange. The first layer takes an excess of moisture, providing penetration of dried air. The enhancing layer holds warm air masses inside due to the special weaving of the threads. The third layer provides a sufficient level of thrust inside the design.
Some types of membranes have an additional anti-condensate layer on a viscose or cellulose basis. It holds the excess moisture, settling on paper fibers. For the natural removal of moisture from the membrane, a technological gap of 2.5 cm is provided between vaporizolation and finishing finish of surfaces.
An important stage of protection of insulation materials is the laying of a reliable vapor insulation layer. All work is carried out in the process of repair or reconstruction. finished building Either when the new structure is erected. To properly perform laying of vapor barrier, it is necessary to understand how to connect the membrane canvases and which side to fix them to the insulation base.
At this stage, work is carried out on the selection of a suitable type of vapor barrier, taking into account the characteristics of the installation process, operational characteristics and material requirements.
Before laying vaporizolation, it will take careful surface preparation. It is important here to consider the type of material used in the construction of floors, walls, ceilings and roofing design.
Wooden elements are processed by the compositions against aging, rotting and burning. Concrete, block and brick surfaces are treated with antiseptic compositions of deep penetration.
Proper surface preparation will provide a long service life of the insulation and the entire structure.
If the roofing construction and the inter-storey overlap are made of wood, then the installation of the membrane for waterproofing is performed on a prepared base.
In the space between rafters and lags, a roll or block insulation is mounted, the best option is mineral or basalt Vata.. Next, you can lay vaporoselation protection on the ceiling surface.
With the thickness of the insulation, equal to the height of the lag, the rush controller is additionally installed to maintain natural ventilation.
Mount the steam barrier barrier on the ceiling is necessary with a small intake on the wall around the perimeter, while special attention should be paid to the corners. The joints are better to place on the lags and sneak from two sides with a reinforced-based basis.
Important! When installing the parobac fence, sagging and deformation of the canvas should avoid.
For thermal insulation flat roof Or the concrete ceiling overlap from the inside is mounted by a waterproofing film on a self-adhesive tape, then a piece of wood or metal is installed.
The height of the crates is determined on the basis of the thickness of the heat insulating material and the minimum technological gap for ventilation. Installation step - 3 cm already the width of the heat insulator, which allows to provide high-quality insulator laying in the prepared cells of the crate.
The scheme of installation of vaporizolation protection on the floor is similar to how the styling of the material on the wall and ceiling surfaces is carried out.
The wooden floor is insulating the lags to which the hydraulic protection is laid. Further, the insulation is laid in the space between them - cotton wool on a mineral or basalt basis. After that, the wrapped line is performed.
Rolled material must be reduced by 12 cm peaks with a thorough sickness of the joints with a metallized tape from both sides. A properly stacked parobarar must completely cover the floor surface with the walls on the wall to 10 cm.
To equip vaporizolation protection on a concrete basis, it will be necessary to install the crate, in the cells of which will be laid hydro insulating layer and thermal insulator.
After the material for the parobac was selected, an important question should be considered - which side is to fix vapor barrier to the insulation. Such materials can be fixed as follows:
Important! Before laying vaporizolation to the insulation, it is recommended to decompose the prepared material on a flat surface to properly define the inner and outdoor side.
If the breathable membrane is used to create a protective barrier, the main thing is to determine which side to lay vapor insulation is face or invalid.
Vapor insulation cake must be put so that the protection is directed to the heat insulator on both sides by a smooth invalid side, and rough facial side - inside the room.
A rough surface provides protection against moisture penetration to the insulation, and the smooth surface contributes to the maximum heat accumulation.
On the edge of the insulating membrane there is a special markup to determine the width of the capetons, which ranges from 8 to 20 cm.
The pair barlasting bands on the roof should be laid in the horizontal plane below the top of the brass at each other in 15 cm wide. Cope is 18 cm, in Undova - 25 cm.
On the walls, ceilings and floors of the canvas are mounted with a 10-15 cm.
At the bottom of the membrane vaporizolation there is a 5-centimeter ventilation gap, which allows preventing condensate formation on surfaces and thermal insulator.
Diffusion membranes can be mounted on the insulation, plywood sheets or OSP. In the membrane with an anti-condensate layer, the gaps of up to 6 cm wide are located on both sides.
To create a gap for ventilation when the roofing structures are insulated with a controller. In the process of fastening the ventilated facade, the technological gap is created when installing racks located perpendicular to vapor barrier.
To securely secure membrane or film vaporizolation, nails with wide hats or metal construction brakes are used. The most practical version of fasteners - counterbashers.
To increase the tightness of the design, individual elements of vapor barrier are additionally sampled by double-sided adhesive tape or wide metallized tape.
To ensure a long service life of modern insulation, high-quality vapor barrier protection will be required. Otherwise, it will be difficult to obtain the optimal ratio of temperature and humidity indicators in the premises. The main thing about this issue is to choose suitable material And know how and what side to perform laying to the heat insulator.
One of the main criteria for a comfortable life in the house is the optimal level of temperature, as well as a suitable humidity. Provide good indicators Correctly mounted layers of heat, moisture and vapor barrier. Moreover, correctly laid layers not only improve the microclimate in the house, but also protect the floors from the effects of various factors, including humidity. How to put steam barrier to the floor?
Parasolation of the floor
Hydro-vapor insulation film
How to put steam barrier to the floor
Inside each house there is a specific microclimate. Here the person is preparing food, takes a shower or bath, is engaged in a wet cleaning. Thanks to all these processes in the air, hovering in the room, there is a sufficiently large number of steam, which is trying to find a way outside the walls of the rooms. It strongly acts on all elements of the structure, and the moisture drops are settled on the surface of the walls, the ceiling, inside the floor cake. The resulting condensation of Will-Neils begins to penetrate the structure of the materials used to build the house - it absorbs into the wood, penetrates the insulation layer, reducing performance features Materials destroying them.
Floor insulation
In rooms located on the first floors right above the soil or basement, the floors also experience an increased impact of humidity. Here moisture affects the materials and below. And vaporizolation stacked just with the aim of lowering the level of exposure to the floors, while this type of material does not interfere with the circulation of air - its streams can quietly go out, the premises will "breathe".
On a note! Parosolation is especially necessary when building houses from a tree. However, it will not be superfluous and in the construction of concrete structures, as it will reduce the level of moisture in the building.
Instructions for steam barrier
Vaporizolation is a thin film that is mounted inside the floor cake. However, it is quite often confused with waterproofing, but these are completely different materials. So, the waterproofing layer is designed to not miss the moisture in the room outside. If the water is still getting to the insulation, then its characteristics will deteriorate significantly - it will stop preserving heat. Especially it will be felt in winterWhen the water inside the insulation layer turns into ice crystalline. The floor will become colder, and in general, it will be no longer so comfortable in the room. That this does not happen, it is necessary to lay a layer of waterproofing. In general, he does not miss the precipitation, groundwater and stacked outside the floor cake.
Floor waterproofing
Parosolation is stacked inside the floor cake. And it will protect materials included in the structure of the base, no longer from moisture from the outside, but on the incoming inside of the room - condensate, which is formed by breathing, cooking food and other processes accompanied by the release of steam and moisture.
Floor diagram on beams
The main difference between these two types of materials is their structure. Waterproofing coatings do not let moisture, but completely capable of missing evaporation. But vaporizolation hold and moisture, and steam, thereby protecting the insulation. Thus, vaporizolation does not have as such a membrane structure.
Pair insulation
On a note! Not all types of waterproofing materials are vapor permeable.
To create a layer of vaporizolation, several main varieties of materials can be used. This is a polyethylene or polypropylene film, the so-called diffuse membrane or liquid rubber. Earlier applied only only tol, rubberoid and other similar materials.
Polyethylene film
Polyethylene film is the cheapest and simple material used to create a layer of vapor barrier. It is thin enough, and therefore, during the installation, it is important to observe accuracy so as not to break it. The film may have a fine perforation or not to have it.
On a note! It is the opinion that the film with perforation is used to arrange waterproofing, and without it - for vapor barrier. This is due to the presence of small holes in the material.
Vapor insulation film "YUTAFOL N 110"
However, in any case, whatever the film, when using it, it will be necessary to equip the ventilation gap. And since it will have to do it anyway, many do not think about the presence of perforations and simply buy that material that it is cheaper.
Now there is another subspecies of films made of polyethylene - it has a reflective layer coated with aluminum. Such material has higher vapor barrier indicators and is usually applied in rooms where high humidity rates are noted, as well as air temperature.
Folgized Film Steam Plant
Polypropylene film is distinguished by high quality and strength. It is simple in laying and is able to serve for many years. The polypropylene film is manufactured not only from polypropylene - it also has an additional pulp and viscose layer, which is able to absorb a lot of moisture to be absorbed and keep it. At the same time, during a decrease in the level of humidity, the layer dries out and again ready to absorb her.
Polypropylene vaporizolation
When laying such a type of film it is worth remembering that the anti-condensate absorbent layer must be rotated away from the insulation. And between the layer itself, a small gap for airborne is left between the layer of vapor barrier and insulation.
Diffuse membranes are perhaps the most expensive vapor barrier. They are considered the highest quality, called "breathable" and are capable not only to protect building materials from excess moisture, but also to regulate the humidity indicator. The membranes are divided into single and double-sided, and materials are mounted differently - if it is important for the flooring of a one-sided version of the membrane to observe which side it will be turned to the insulation, the two-way can be laid as you like.
Such membranes are distinguished by significant indicators of vapor permeability. They are produced from a special nonwoven artificial material and can have several layers. When installing, leave the gap for ventilation is not necessary.
Diffuse membrane
On a note! Among the membranes there are those that were called "Intellectual". They combine several properties in themselves - capable of working as a vapor insulating layer, provide waterproofing and are also thermal insulating material. This type of membrane is able to adjust the steam level, depending on what levels of such indicators as ambient temperature and indoor humidity.
Liquid rubber when creating a wooden floor cake is used extremely rare for vapor barrier, it is more suitable for bases from concrete. However, it is still a fairly common option to tell about it. Such rubber is a polymer-bitumen composition prepared on the basis of water. It is applied very simply - sprayed on the ground, moreover, it forms a seamless and durable coating - a sort of rubber carpet. When the polymerization process is completed, the material will not be able to pass any substances through itself.
Liquid rubber
Liquid rubber can be applied automatically and used for processing spacious structures or manually - this option is suitable for small rooms.
In the materials market there are a wide variety of all sorts of grades of vapor insulation materials. They have a lot of differences and may differ in price, quality and other factors.

"Izospan in"
Especially popular is the Izospan. Its there are several subspecies, and for floors it is recommended to acquire Izospan V. It is a two-layer membrane. On the one hand he is smooth, and on the other hand, slightly grungy. The rough side is well kept capillary moisture, absorbing it.
The cake of the floor is made of several layers, including lags, a layer of waterproofing material, a rough floor, a layer of insulation, a vaporizolation layer, a layer of soundproofing material and the finish coating. Before installing vaporizolation, it is necessary to prepare the surface. If the building is erected from scratch, there will be no problems with the installation of this layer. The blackboard boards are simply processed by antiseptic preparations, aligned, and the vapor insulation material is spilled on top of them. It is also recommended to cover protective compositions and lags.
Mineral wool floor insulation
If the house is already erected, its overhaul is carried out, then it is important to remove the old flooring and other materials used to be removed. Next, it is important to check for the strength of the lags, a draft base - if they bend or have fallen, they will have to be dismantled and replaced with new ones. All the garbage before further work is removed, the smallest safes are removed using a vacuum cleaner.
The vapor barrier layer should be laid on even, without protruding nails base. Otherwise, it may be damaged. Immediately before installation, it is important to determine which side will be mounted vapor insulation material. As for the ordinary film from polyethylene, it will not be necessary to define the side. If the isospan is used, it is important to look at its color on both sides. It is placed by the light side to the insulation. If the material has a pile, then it is mounted in the direction of the room - the pile will absorb excess moisture.
Laying vaporizolation "Izospan"
On a note! To work with vapor insulation, such material is useful as tape. With it, the joints of individual coating strips are connected. This is necessary to improve the tightness of the vapor insulating layer. At the same time, individual strips of the material are put on top 15-20 cm on each other.
Special knowledge installation of vaporizolation does not require. The material is rolled over the surface of the prepared floor and is fixed on it using small nails, a construction stapler. However, the easiest way to use a special sticky ribbon.
Inquitable or having an unusual place, it is best to additionally process a bitume-based coem. The reason for these actions is that in such places to lay and properly fasten the vapor insulation material quite problematic.
The process of laying "Izospan"
On top of the vaporizolation, the insulation itself will be laid directly if the material is used to protect it from moisture not only from the inside, but also outside. A foam, minvat or expanded polystyrene can be used as a warming interlayer. He must very firmly fit wooden lagumSo as not to formed the bridges of the cold.
From above on a layer of insulation, another layer of vapor insulation is mounted. It will no longer allow moisture coming from the inside of the room, get to the insulation and absorb him.
On a note! Foil film perfectly reflects infrared radiation. Therefore, it is placed in a brilliant side in the direction of the room.
Parosolation should be configured to comply with technology, although in general this process is quite simple and understood to everyone.
Step 1. Windproof material spreads over the rough floor.

Step 9. The place of adjoining the next layer of the film is sealed with a sticky tape, which is pasted along the edge of the previously stacked layer.
The joints between the sections of the film are sealed with sticky ribbon
Step 10. The new segment of the material is stacked so that it turns out the launch in the location of the sticky tape. The rest of it is fixed again on the lags with the help of a construction stapler.
The second segment of the vapor barrier film is stacked
Step 11. Installation of floors.
Installation of the floor
Parosolation - a layer in a cake of the floor, which should not be neglected and even more so - to replace it with waterproofing material. It is thanks to vaporizolation that will create a favorable microclimate in the house.
During the repair of the house, it is important to comply with the technology of dismantling, processing and assembling all surfaces: walls, ceiling, floor, roof. Often homegrown builders neglect such an important detailAs a vapor insulation material, by ignorance or argueing it inappropriate. It often happens that the hired repair brigades make unforgivable mistakes for which you still have to pay. In fact, vaporizolation serves as a barrier to penetrate moisture from the outside to the floor "cake", prevents the occurrence of condensate, fungus and rotting processes. Therefore, it is extremely important to know how to choose how to choose vapor insulation on the floor and which side.
To protect surfaces and insulation from moisture, use:
The main role of vapor insulation material is the protection of wooden structures and insulation material from moisture, rotting and, as a result, premature destruction.
It is extremely important to use it on the lower floors above the basements and basement rooms, and especially above the bathrooms and kitchens. It is also necessary to remember that the protection of the insulation must be bilateral, since the wet mineral or glass gamble almost completely loses its thermal insulation qualities. That is, the film is placed between the finishing floor and the material for insulation, as well as between the insulation and the draft floor. However, often the bottom layer is replaced with waterproofing.
You need to know which side to lay vapor barrier to the floor. Extremely an important nuanceSince the wrong material mounting technology will reduce all its properties.

In winter, when frost on the street, and in the house is cozy and warm, in the rooms there is an imperceptible pairs. And this couple should freely leave the room. To perform this task, steam barrier is laid. It is necessary to know which side to lay vapor insulation on the floor, wall or ceiling.
Vapor insulation material is used to normal circulation of moisture indoors. If you ignore vaporizolation, then the moisture in the air can fall into the insulation and gradually destroy the material.
If the construction of buildings is performed from the material, which is already insulation, then vaporizolation will serve as protection from entering the placement of harmful substances.
Insulation - thermal insulation material. Depending on the origin of the original raw material is divided into:
What a vapor insulation is needed
Installation of the vapor barrier layer is carried out to maintain a comfortable temperature inside the house, not allowing air to penetrate through the slots of the building.
Applying the insulation, which absorbs moisture well, can not do without vaporizolation. In its absence, moisture is absorbed into the structure of the insulation and turns into water there. With time heat insulating characteristics Heating material will decrease. After a certain period, the appearance of fungus and mold can be observed. The use of vapor barrier creates a certain shield between the insulation and the inner air of the apartment.
The correct installation of a vapor barrier will allow the insulation to stop long and efficiently.
IN modern construction Parosolation is successfully used to protect organic and inorganic thermal insulation materials. It happens the following types:
Film - Deaf vapor insulation material that keeps moisture and does not miss through itself. Due to its low cost and excellent waterproof characteristics, the film is applied not only in the construction industry, but also for household needs. Films differ in thickness, the number of layers, surface quality. It is smooth on the outside and rough with the inner. Water always remains on the surface of the film.
Summary Table of Vapor Isolation Film Properties
Diffusion membrane. This type of vapor barrier material consists of a polymer film and polypropylene, has limited vapor permeability. Water pairs, located in the insulation, are evaporated immediately.
Energy saving membraneresistant to elevated external medium temperatures due to its metallized external layer. Laying vaporizolation should be indoors with high humidity and temperature. Material is able to reflect infrared radiation.
Roll vaporizolation I misses moisture in two directions. It is convenient to use when insulated the surface of a large area.
Thermal insulation and vaporizolation characteristics of the structure depend on the selection of the material. A careful approach to the selection of necessary products will ensure comfort and comfort of premises and will help extend the life of the entire structure.
Manufacturers of vapor insulation films, focusing on the consumer's desire, produce their products in different directions:
Parasolation installation options
You can lay vaporizolation on any surface. When using vapor insulation material on wooden structures Apply a film with a membrane. Polymer or bituminous mastic You can use for any type of surface. On the concrete walls Recommend to lay vapor barrier with a metal outer layer.
Its application will be much more efficient if the work side is prepared in advance. Preliminary works depend on the characteristics of the material with which the building is built.
Breathable membranes
During construction wooden houseFor beginnings, all the wooden surfaces are impregnated with insects and harmful bacteria. Only after the completion of the preparatory complex is taken for the installation of the vapor insulating layer.
The most quality material for wasolation of wooden floors is breathing membranes. The membrane body consists of a layer of anti-condensation fibers that absorb and accumulate moisture. There are one-sided and double-sided membranes. In the last version, the moisture absorbs immediately on both sides, so the two-way breathable membrane can be stacked by any side to the floor.
When conducting overhaul All outdated insulating coatings dismantle. Carefully produced surfaces, their impregnation with special disinfectant compositions. Then you can lay vaporizolation. Concrete surfaces Do not require separate workshop processing, they can be cleaned enough.
Installation of a vaporizolizing layer does not represent a special difficulty, it is necessary to carefully perform preparatory work and know the main stages of installation.
The film is the optimal option of floor insulation from moisture. On the first floor layer of the insulation, the bottom is protected by the waterproofing device, and closer to the room - a rolled insulating film that is stacked by the Vangest. The joints are sampled with a metallized ribbon or scotch.
If it is an inter-storey or attic overlap, then the film is deployed by a smooth side down to protect against water vapor coming from the slab or overlap logs.
Parosolation floor laying
It is used in rooms with high moisture content in the air. It can be bathrooms, showers, baths, saunas. Parosolation is reliably superimposed with joint sealing of joints. The reflecting side of the material is sent inside the room. Special attention is paid to the corners of the room, the insulation must be slightly overlapped on the walls throughout the perimeter of the room.
Ceiling insulation vaporizolation
For such surfaces, diffusion membranes are used, which paste air, and not moisture. Walls must "breathe", so the impermeable film is not used. In the case of external work, the product is placed by a smooth side to the insulation. When installing, the film is slightly stretched.
Isolation of walls
The challenge of the Parobarker is to protect the rafted from mold and the obstacle to the formation of condensate in the insulation layer. Installation is made by penetration with seam sealing. The basic condition is to ensure the tightness of the roof in the complex with vertical elements of the building.
Steamproofing Roof - Device
Balconies, basements and underground rooms are contacted with cold outer air. For balconies, a dense foamed polyethylene is used, which reflects the side of which is sent inside the room. For other structures, a membrane film is used.
Insulation underground facilities
When working with vaporizolizing materials, it is necessary to find out which side the product should be stacked with respect to the insulation. By the location of vaporizolation, the degree of absorption of moisture insulation and its operation will be dependent. The instructions for the product indicate how to lay it correctly. But if there is no instruction? In this case, the installation method is determined by independently, given the following points:
Polyethylene film is placed by any side to the insulation, while the diffusion film has one smooth surface, which should fall toward the insulation. Preventing the wetting of the insulation layer, allows moisture to be easily passing through a smooth side.
Installation of vaporizolation
When performing work on the installation of a vapor barrier film, it is important that the product is attached correctly. Otherwise, the error will lead to ineffective thermal insulation.

Parosolation is a layer protecting the insulation or building structures from the penetration of a wet steam, which in turn, to the accumulation of condensate on them, loss useful properties and rotting under the influence of moisture. To create a parobacker, completely impenetrable bilateral or having one right working surface of the film and canvas can be used. It is extremely important to accurately determine which side to lay vapor insulation on the insulation, the error at this stage provokes the accelerated destruction of building materials and significant financial costs. The main indicator is the manufacturer's instruction, but there is often no such document when buying is not available, the choice is carried out from the view of the type of vapor barrier film and installation conditions.
For conventional or bilateral reinforced polyethylene, this problem is not relevant, in other cases, working is impermeable to the surface. Most often, vaporizolation is laid by a smooth side to the insulation, and the protected - refers to the source of the penetration of steam. Depending on the type of materials, this is:
1. Laying vapor insulation on the floor.
Protection against steam and moisture is required when heating overlaps or horizontal planes, assembling structures from a bar. Reflective films that return heat into the house are optimal for the floor. Upon the construction or repair of the first floors, the insulation is protected by a layer of waterproofing, and with top-roll vapor barrier materials stacked by the bracket (from 10 cm and above) with a metallized tape sample. A slightly different situation with the arrangement of attic floors and inter-storey floors: the films rotate the impermeable side down to protect against penetrating the logs or steam slabs.
2. Vaporizoation of ceiling structures.
Most often, the need for closing the ceiling occurs in the baths, saunas, kitchen, shower and other structures with high humidity. The larger the volume of the vapor and above their temperature, the more reliably vaporizolation is required. To protect the ceilings, the steam rooms are well suited dense aluminum, lavsan and antioxidant vapor barrier materials, for residential rooms - the same, plus the usual foam. A prerequisite is nesting at least 10-15 cm and sealing joints, for reliability, the parobarar is fixed on the ceiling with grille or brackets. In this case, the reflective or countertile side is directed solely inside the room.
3. Vertical designs.
Installation of the Parobarker when insulation of walls is necessary when: using fibrous and cotton insulation, erection of frame wall panels, arrangement of ventilated facades, in the latter case, in addition, it performs the windscreen functions. In all mentioned moments, it is not recommended to choose completely impenetrable films, the insulation must breathe, diffusion and superdiffusion membranes transmitting air, but not moisture and steam are considered the optimal option. With external work, vaporizolation is laid by a smooth side to the Minvat or to another insulation on the walls, Schelava - towards the street. Film or canvases should not be saved, but also excessive tension is also unacceptable. On domestic vertical Walls They keep at the expense of a bracket or upholstery with thin straps, a steamproof side to the room.
4. Steamproofing roof.
The parobararier is a mandatory layer when laying roofing pie. It prevents the accumulation of condensate in the inner insulation layer and protects rafters from fungus. From vaporizolation requires the highest possible tightness, preference is given to antioxidant and reflective species, impermeable to the pair side is directed inside attic room. Fall - from 15 cm, as well as sizing joints and seams. An important condition is the need for sealing of vapor insulation materials adjacent to vertical structures.
5. Other applications.
The parobararier is also needed when insulation basement and balconies (zones in contact with cold outer surfaces. For basement and underground sections, membrane films, walls and basement ceilings should be breathed, the floors are insulated from the ground. For the installation of vaporizolation when the balconies and loggia are insulation, the preference is given to the foamed polyethylene with the reflective side. Directed in the apartment. This is almost the only case when materials are placed on jack, and not a mustleless, but the sealing of neighboring sites is still obligatory.
Possible mistakes
In addition to choosing the wrong side to violations of technology:
1. Lack of adhesive or insufficient insulation of the joints.
2. Tensioning thin films, especially on structures subject to temperature drops, this leads to their rupture. But excessive sagging is also not required.
3. Lack of ventilation gaps for evaporation of condensate from the filmproof the side of the film (a bright example of an error - installation of the inner lining directly to the bottom layer of roofing cake).
Before laying vaporizolation, its required quantity should be calculated. Using different types It is undesirable, although there are no clear standards in this case. A common mistake is to buy rolls strictly on the area of \u200b\u200bwork surfaces without a reserve by 15% of the adhesive and banal damage.
There is a single option when putting vaporizolation is not necessary - when erecting a house from wooden barBut this exception does not apply to absorbing insulation materials and floors, they always need protection. Works are carried out in warm and, if possible, dry season, the films will in every way caress from wetting. An important condition is the dense adjoining of vapor barrier to the insulation (the ventilation gaps remain with an external, reflective and impermeable side), emptiness and sagging are unacceptable. All surfaces must be clean, degreased and dry.
In case of doubt in the correctness of the decision, which side laid vapor barrier to the insulation should once again become familiar with the instructions. Reflective and rough plane is easily determined, with membranes more difficult. Typically, the inner is considered to be facing down when the side of the roll is unfolding. Experts advise pay attention to coloring: Lighter shades are observed in the sides adjacent to the insulation. But there is a variety that matte (most often fabric) surface is playproofable. If this is not enough to identify the desired properties, the web or the film is slightly rolled down on the floor, the tight fit of the material and will be internal.
When building a country house or private bath, an important step is the thermal insulation of various surfaces. In addition, the insulation itself needs high-quality and reliable vapor insulation protection. In order to prevent the negative impact of external factors and the formation of condensate on the thermal insulator, any homeowner must have a general idea of \u200b\u200bhow to properly lay vaporizolation to ensure a long service life of the whole structure.
The most patched on its operational characteristics are breathing multilayer membranes, which are designed to create reliable vapor barrier protection.
They consist of three layers, each of which performs an important function. The first layer warns the penetration of steam into the insulation, the second ensures the necessary strength of the base, the third protects against moisture from the outside.
Each individual layer has the necessary perforation for a good air exchange. The first layer takes an excess of moisture, providing penetration of dried air. The enhancing layer holds warm air masses inside due to the special weaving of the threads. The third layer provides a sufficient level of thrust inside the design.
Some types of membranes have an additional anti-condensate layer on a viscose or cellulose basis. It holds the excess moisture, settling on paper fibers. For the natural removal of moisture from the membrane, a technological gap of 2.5 cm is provided between vaporizolation and finishing finish of surfaces.
An important stage of protection of insulation materials is the laying of a reliable vapor insulation layer. All work is carried out in the process of repair or reconstruction of the finished building or when the new structure is erected. To properly perform laying of vapor barrier, it is necessary to understand how to connect the membrane canvases and which side to fix them to the insulation base.
At this stage, work is carried out on the selection of a suitable type of vapor barrier, taking into account the characteristics of the installation process, operational characteristics and material requirements.
Before laying vaporizolation, it will take careful surface preparation. It is important here to consider the type of material used in the construction of floors, walls, ceilings and roofing design.
Wooden elements are processed by the compositions against aging, rotting and burning. Concrete, block and brick surfaces are treated with antiseptic compositions of deep penetration.
Proper surface preparation will provide a long service life of the insulation and the entire structure.
If the roofing construction and the inter-storey overlap are made of wood, then the installation of the membrane for waterproofing is performed on a prepared base.
A rolled or block insulation is mounted in the space between rafters and lags, the best option is mineral or basalt wool. Next, you can lay vaporoselation protection on the ceiling surface.
With the thickness of the insulation, equal to the height of the lag, the rush controller is additionally installed to maintain natural ventilation.
Mount the steam barrier barrier on the ceiling is necessary with a small intake on the wall around the perimeter, while special attention should be paid to the corners. The joints are better to place on the lags and sneak from two sides with a reinforced-based basis.
Important! When installing the parobac fence, sagging and deformation of the canvas should avoid.
For thermal insulation of a flat roof or concrete ceiling overlap, a waterproofing film on a self-adhesive tape is mounted, then a tree or metal doom is installed.
The height of the crates is determined on the basis of the thickness of the heat insulating material and the minimum technological gap for ventilation. Installation step - 3 cm already the width of the heat insulator, which allows to provide high-quality insulator laying in the prepared cells of the crate.
The scheme of installation of vaporizolation protection on the floor is similar to how the styling of the material on the wall and ceiling surfaces is carried out.
The wooden floor is insulating the lags to which the hydraulic protection is laid. Further, the insulation is laid in the space between them - cotton wool on a mineral or basalt basis. After that, the wrapped line is performed.
Rolled material must be reduced by 12 cm peaks with a thorough sickness of the joints with a metallized tape from both sides. A properly stacked parobarar must completely cover the floor surface with the walls on the wall to 10 cm.
To equip vaporizolation protection for a concrete basis, the installation of the crate, in the cells of which the waterproofing layer and the heat insulator will be laid.
After the material for the parobac was selected, an important question should be considered - which side is to fix vapor barrier to the insulation. Such materials can be fixed as follows:
Important! Before laying vaporizolation to the insulation, it is recommended to decompose the prepared material on a flat surface to properly define the inner and outdoor side.
If the breathable membrane is used to create a protective barrier, the main thing is to determine which side to lay vapor insulation is face or invalid.
The vapor insulation cake must be put so that the protection is directed to the thermal insulator on both sides by a smooth invalid side, and a rough face - inside the room.
A rough surface provides protection against moisture penetration to the insulation, and the smooth surface contributes to the maximum heat accumulation.
On the edge of the insulating membrane there is a special markup to determine the width of the capetons, which ranges from 8 to 20 cm.
The pair barlasting bands on the roof should be laid in the horizontal plane below the top of the brass at each other in 15 cm wide. Cope is 18 cm, in Undova - 25 cm.
On the walls, ceilings and floors of the canvas are mounted with a 10-15 cm.
At the bottom of the membrane vaporizolation there is a 5-centimeter ventilation gap, which allows preventing condensate formation on surfaces and thermal insulator.
Diffusion membranes can be mounted on the insulation, plywood sheets or OSP. In the membrane with an anti-condensate layer, the gaps of up to 6 cm wide are located on both sides.
To create a gap for ventilation when the roofing structures are insulated with a controller. In the process of fastening the ventilated facade, the technological gap is created when installing racks located perpendicular to vapor barrier.
To securely secure membrane or film vaporizolation, nails with wide hats or metal construction brakes are used. The most practical version of fasteners - counterbashers.
To increase the tightness of the design, individual elements of vapor barrier are additionally sampled by double-sided adhesive tape or wide metallized tape.
To ensure a long service life of modern insulation, high-quality vapor barrier protection will be required. Otherwise, it will be difficult to obtain the optimal ratio of temperature and humidity indicators in the premises. The main thing about this issue is to choose the right material and know how and what side to perform laying to the heat insulator.
A rather common problem after the insulation of the house is the absence of an expected effect from the works work. It would seem that the traditional material was chosen, for example, mineral wool, everything was completed on construction laws and canons, and indoors still cold. The reason for this may be ignorance by the "specialists" of elementary norms, including which side to the insulation to lay vaporizolation. Let's figure it out in more detail in this matter.
Parosolation is divided into two types by means of applying:
Painting vaporizolation is applied with the help of brushes and rollers in places where rolled vapor insulation is difficult for fan and chimneys. This family of vaporizolyators is represented by such materials as bitumen, tar and tar.
Parosolation membranes
First of all, we will define the types of vapor barrier films in their intended purpose. In terms of its specificity, the membranes used in construction are offered in the following execution:
To protect the Minvati from the impact on it, moisture from the inside must additionally be reduced by a layer of vaporizolation. When the roof insulation, the floor or the inner space of the house, located directly under it, is recommended to use the appropriate film. Note that the insulating layer is placed below, under the laid mineral wool (from the side of the room).
In cases where the external protection of the walls is performed, the corresponding components should not have perforations or pores.
Always pay attention to the value of the vapor permeability ratio than it is less, the better for you. Excellent option Is the usual polyethylene film. The ideal choice will be material with additional reinforcement. The presence of a foil aluminum coating is considered only a plus.
Do not forget that the presence of vapor barrier finishes leads to a multiple increase in humidity in a warmed space, so you should take care of a good ventilation system in advance.
Polyethylene reinforced film
Existing special vapor barrier films are performed with antioxidant coating. Due to it, the moisture cluster does not occur. As a rule, they are fixed under the components sensitive to the formation of rust. We are talking about metal tile, professional flooring, galvanizing, etc. A rough fabric layer on the wrong part of the film is guaranteed to effectively derive moisture. It is placed by the treated side to the insulation, and the tissue outward, so that the distance 20-60 mm remains until the minvate.

Performing insulation of walls of the house outside, a construction membrane is used, capable of evaporation, protect the material from strong wind gusts. In addition, it is suitable for protecting the roof of a rock type, the facade with a leakage of moisture. Often the vapor barrier film has very small pores and perforation of the surface, due to which the water is effectively excreted from the insulation to the ventilation channels. The process is the better, the more actively evaporations take place. This will allow you to quickly and qualitatively dry by insulation.
Distinguish the following types of vapor-permeable films:
Since the first type of isolation is considered good protection against moisture effects, it is often located under the surface of the roof as an outer layer. Additionally, the air breakfast is required between the insulation layer and the film. At the same time, the specified component is not suitable for facade processing, since it is bad enough steam. This is due to the penetration of dust membrane and another garbage in a dry time, the "breathable" effect and condensate disappears to accumulate on the surface of the insulation.
Super Diffusional Membrane Izodach 115
The two remaining membranes have large pores, it eliminates the likelihood of their blockage, due to which there is no need to leave the air ventilation layer at the bottom. As a result, it will not be necessary to mount the crate and counterbask.
There are diffusion films of volumetric performance. Inside the membrane is already provided by ventilating layer, due to which moisture will not be able to get to metal surfaces. The specificity of the film device is similar to the antioxidant option. The difference lies only in the output of moisture from the insulation. It is beneficial, because when the roof is tilted, even at a low angle of 3-15 degrees, the possibility of condensate flowing through the bottom is excluded. Therefore, corrosion of galvanized coating will gradually occur, followed by its final destruction.
Which side to the insulation is to mount vaporizolation
First you need to figure out which places the laying of a vapor insulation membrane may be needed, and then defined with the side of vaporizolation.
Many "experienced" builders even have no idea how the vapor barrier membrane should be attached: the front or invalid side.
The best solution will be the use of material with the same invalid and face.
And what to do in the case of one-sided option, in particular with antioxidant insulator? It is necessary to know that the withdrawal side is the tissue surface, located during the styling in the inner part of the room.
Parapolation side laying side
In the same direction refers to a metal plane foil membrane - Brilliant side of the premises inside.
For anyone film insulation materials The following rule acts: the smooth side is stacked to the insulation, while the rough side must be addressed to the room.
The same rule concerns painrophy vapor insulatorswho are put on a smooth side to the insulation.
Parosolation is placed in the dark side to the insulation
It should be borne in mind that when rolling the roll, for example, by the floor, the inner side should be on the floor.
In addition, most often the darker side is outdoor.
Does the air layer need a membrane?
Leave it always. From the bottom side of the films, a special clearance of up to 50 mm wide is arranged. This will avoid the appearance of condensate on the walls, gender and insulation. It is important to avoid contacting surface cladding with membrane. Applying a diffusion film for the floor, walls or ceiling, you save yourself from many problems, since it can be made directly on the heat insulator, OSP or moisture-resistant fane. The ventilation layer will need from the outside of the membrane. In an embodiment with an antioxidant component, the air clearance should be within 40-60 mm on both sides.
Organization of Ventzazor when laying vaporizolation
If everything is clear with the walls and floors, then with the roof and the ceiling, the situation is kept by a mansion. When performing a ventilation gap, an additional installation will be required by wooden bars based. When organizing a ventilated facade, the clearance is left when the horizontal profiles and stands are erected, located perpendicular to the wall and film.

How the vaporizolation is attached
The fixation of the membrane to the walls, the floor or ceiling can be carried out by nails with a wide hat or a construction stapler. but best selection It will be using counterchains.
The laying of vaporizolation is carried out with the overlap with a minimum of 10 cm. After fixing the vapor barrier, the joints are sampled by a special scotch or a ribbon for vapor barrier.
Conclusion
In conclusion, let's say that membranes will allow any construction design to serve the maximum long time. In other ways to achieve a positive ratio of moisture and temperature, alas, not achieve. In addition, you should not forget about the rules for laying vaporizolation. Most manufacturers together with the goods also distribute installation instructions. This is especially true of diffusion and superdiffusion membranes. Therefore, do not be lazy before the acquisition to clarify the seller-consultant all your questions.
Warming is a very important stage in the construction or repair of the house, on which it depends, whether you will be comfortable in it. Incorrect conduct of this "procedure" can lead to unpleasant consequences, for example, the allocation of condensate, increasing the humidity in the air. But this will not arise if you take care of vaporizolation and put it with the right side to the insulation.
Features
During the insulation of the house, it is necessary to carefully comply with the correct sequence of actions and use only the best materials. Unfortunately, often the owners who are taken on their own to warm their home, forget about one very important aspect - about the vaporizolator. They only install the insulation and do not even think that it is in contact with the too warm or too cold air indoors, and that soon it will begin to form condensate in the form of water droplets.
And this not only does not contribute to insulation, but also spoils the material - moisturizes it, and if the couple does not have time to evaporate, the mold appears, and the construction of the insulation is spoiled. Moreover, taking into account our climatic conditions, such a situation occurs at least four times a year - when seasons are replaced and, accordingly, the temperature in the room and outside its limits "conflict" and the Battle field becomes precisely insulation.
That is why an important stage of insulation is the fastening of the "vapor barrier". The vaporizolator becomes an impassable obstacle for the steam, prevents it into water, because it "closes" into the room indoors and does not allow it to be in charge with an unnecessary warm or excessive cold air.
Materials
Steam barrier can be performed using several materials. Three main types should be distinguished from this set.
As you know, for the insulation of houses in modern conditions Materials such as minvat, polystyrene foam, eco-house are used. Variazolation is needed and in the case of the insulation of minvata.
In fact, vaporizolation is always needed, regardless of how expensive or high-quality material for insulation you use. Minvata or Mineral Wat is otherwise the cheapest materials, but the thermal conductivity level is low, which reduces the likelihood of heat loss in the room. Minvatu does not like rodents, mold, fungus, it has high noise insulation and is easily mounted. But still requires vaporizolation for himself.
Most often a vapor-permeable limited diffusion membrane is used. It stacked the walls, after her you need to drain Minvatu, and in symbiosis they allow the walls of the house "breathe".
The question of vapor barrier arises and when the house is insulated with an Eco-house. In general, the eco-fiber is the flushed cellulose fibers, having the ability to absorb warm moisture and while remain dry. It is not breeding fungus, mold, the air in it simply does not swing (if the changes in humidity does not exceed 25% percent). It follows from all that follows that just in the case of an eco-art vaporizolator can not be attached.
Another popular insulation - polystyrene foam actually has another more easily the name of the foam. It lies both on the outer surfaces and internal, and in the case of the outer insulation of loggias, balconies or attic overlap Parosolation does not require - he himself, when existing insulation technology, copes well with this. But if you insulate the foam indoor rooms, vaporizolation and waterproofing are required to avoid the formation of fungus, mold and wetting walls.
Device
Acquisition of a set of high-quality materials - only a third of success. In fact, these materials must be properly installed, arrange in the right sequence. It is for this that you should find out which side of the vaporizolation is stacked, as fixed, in what order and what to be selected earlier is a vapor polypoletor or insulation.
First you need to prepare work. At this stage, the type of coating is revealed, which you will warm up, its operational characteristics and the requirements for the material of the insulation and the vaporizolator.
So, the surface is required to carefully prepare. This takes into account the type of material from which it is made. Wooden elements must be processed against aging, rotting and burning. In the case of concrete and brick, the antiseptic compositions of deep penetration takes place. Half success in its operation depends on the proper surface treatment.
If you are repaired or reconstructed, then pay attention to the fact that all traces of the previous finish must be removed before insulation, complete stripping is performed. And if we are talking about a litter, then all the elements should be processed with antipirens and antiseptics.
Parosolation on the ceiling
In the case of roofing structures and inter-storey overlap, the installation of vaporizolation is assumed to be already prepared and properly processed surface. It is best to use a diffusion membrane here.
The main difference in laying steampoles to the ceiling from laying it onto other surfaces is that in this case the insulation is first stacked, and then the membrane. It may be mineral or basalt wool in blocks or rolls. It is mounted between lags and rafters. If the insulation thickness will be equal to the height of the lag, you will need to additionally fulfill the rush counterclaim so that the ceiling is ventilated. After all, you can go and vaporizolator.
It must drop a little on the wall around the perimeter, the joints should be attached to the lags - to ensure that the moisture will not fall into the space between the membrane and insulation. Special attention is paid to the corners - these are problem places, it is better to take them additionally. As a retainer, use tape on a reinforced-based basis or a construction stapler.
In the case of insulation of a flat roof or concrete ceiling, an ordinary vapor insulation film can also be used. It is attached to self-adhesive tape, also after the insulation, and then the root is installed - metal or wooden.
Parosolation on the floor
In the case of laying a vapor insulation on a wooden floor, you should additionally install hydraulic protection. The floor is also insulated by lags. The space between lags is installed minvat or wool on basalt basis. Next, without any additional work, steamers are performed.
If we are talking about a rolled vaporizolator, but it is stacked by 12-15 cm with the most thorough sickness of the joints, gaps and slots on two sides with a metallized scotch. As in the case of the ceiling insulation, the wall scatter should be within 10 cm.
For concrete sex, it will take a doom. You will need to put a waterproofing layer in the cells of the root, from above - the heat insulator, and after the Minvata, a paro insulator goes the third layer.
Parosolation on the wall
The process of insulation and vaporizolation of the walls is slightly complicated than the execution of the same work on the ceiling or semi and implies a slightly larger number of stages. Consider the process of laying a vapor barrier film on the walls.
The first thing from small cross section bars is mounted frame. The size of the root is caused by the width of the thermal insulator block - the distance between the cells is equal to the width of one plate. Classically use Minvatu.
At this stage, special attention should be paid for possible gaps arising from the difference in the width of the insulation, frame and vapor polypoletor. The gaps are close to reinforced with scotch, and film sheets are glued horizontally spin at 15 cm.
Subtleties of mounting
When installing vaporizolation, special attention should be paid on important issues.
Which side to lay vaporizoation?
Very often, the masters find it difficult to answer this question, but everything is not so difficult. The usual film has the same facial and irons - and then it does not matter which side to lay it. But in the case of one-sided film, the situation is slightly harder.
For example, antioxidant films from the fabric, and according to the installation requirements, it should look inside the room. Parokone films need to be putting a smooth side to the insulation, rough - out. But with diffusion films should be viewed directly into the instructions, as such films can be both one-sided and double-sided. Energy-saving films are fitted with a foil side, on the contrary, outward - after all, they must reflect, and not absorb heat. The same applies to metal coatings.
How to distinguish the outside from the inner?
This information should be specified in the instructions or on the manufacturer's website, you can ask about this consultant or master. However, if nothing from the above is suitable for you, you will have to learn how to determine the parties of vaporizolation yourself.
So, remember: if vaporizolation is two-color sides, the light side will always be laid down to the insulation.
But also pay attention to how the pair polypoletor roll rolls - the side that is addressed to the floor will be internal, and should be put on the insulation. In the case of a vapor polypoletor with a different surface, a smooth layer will always be internal, and a dusty or grungy - outdoor.
What fastener should be used?
It can be either an ordinary building stapler or nails with a wide hat, but the best option It is customary to count the counterbours.
Does the air layer do you need near the membrane?
It is believed that this is a mandatory point - it is categorically impossible that the wall comes into contact with the membrane close, you should leave a clearance for ventilation of about five centimeters. Condensate will not accumulate in this way. In the case of a diffusion vapor polypoletor, the air layer is made with the outside, and the film itself is placed directly on the insulation.
Do I need to smoke joints?
It is also necessarily - individual parts of the vaporizolyators should be hermetically attached to each other without the formation of gaps, the same applies to the places of fastening of vaporiescence to the windows or doors. For this purpose, self-adhesive tapes are used - double-sided or unilateral, are usually made of polyethylene or butylene, propylene. These tapes are not only perfectly bonded between membranes, but also used when they are repaired - they can be sealing holes and cracks.
In no case do not use tape for this, better contact the seller-consultant in the building materials store or go to the company's website, which has purchased a vaporizolator - as a rule, companies produce materials to repair their products.
The main goal of vaporizolation is not allowed water to leave the room through the insulation and the surface. This means that pairs, one way or another, remain indoors, and in order for humidity not to increase, and the microclimate does not violate, it is required to carry out natural or forced ventilation.
If you are interested in the question of what to do in the event of a membrane part of each other, we advise you to pay attention to the film yourself. Along their edge there is a markup - she also says how specifically there should be a fallen film. Depending on the type and firm, the value that is indicated there is at least 10 cm and not more than 20.
And also pay attention to the corner of the roof. If it is less than 30 degrees, the Fedlast can not be more than 10 cm. If less than 20 degrees - Farm cannot be less than 20 cm.
On the installation of vaporizolation of the roof and about which side to lay paosoolence to the insulation, see the next video.

The main difference in laying steampoles to the ceiling from laying it onto other surfaces is that in this case the insulation is first stacked, and then the membrane. It may be mineral or basalt wool in blocks or rolls. It is mounted between lags and rafters. If the insulation thickness will be equal to the height of the lag, you will need to additionally fulfill the rush counterclaim so that the ceiling is ventilated. After all, you can go and vaporizolator.
It must drop a little on the wall around the perimeter, the joints should be attached to the lags - to ensure that the moisture will not fall into the space between the membrane and insulation. Special attention is paid to the corners - these are problem places, it is better to take them additionally. As a retainer, use tape on a reinforced-based basis or a construction stapler.
In the case of insulation of a flat roof or concrete ceiling, an ordinary vapor insulation film can also be used. It is attached to self-adhesive tape, also after the insulation, and then the root is installed - metal or wooden.
In the case of laying a vapor insulation on a wooden floor, you should additionally install hydraulic protection. The floor is also insulated by lags. The space between lags is installed minvat or wool on basalt basis. Next, without any additional work, steamers are performed.
If we are talking about a rolled vaporizolator, but it is stacked by 12-15 cm with the most thorough sickness of the joints, gaps and slots on two sides with a metallized scotch. As in the case of the ceiling insulation, the wall scatter should be within 10 cm.
For concrete sex, it will take a doom. You will need to put a waterproofing layer in the cells of the root, from above - the heat insulator, and after the Minvata, a paro insulator goes the third layer.
The process of insulation and vaporizolation of the walls is slightly complicated than the execution of the same work on the ceiling or semi and implies a slightly larger number of stages. Consider the process of laying a vapor barrier film on the walls.
The first thing from small cross section bars is mounted frame. The size of the root is caused by the width of the thermal insulator block - the distance between the cells is equal to the width of one plate. Classically use Minvatu.
At this stage, special attention should be paid for possible gaps arising from the difference in the width of the insulation, frame and vapor polypoletor. The gaps are close to reinforced with scotch, and film sheets are glued horizontally spin at 15 cm.
When installing vaporizolation, special attention should be paid on important issues.
Very often, the masters find it difficult to answer this question, but everything is not so difficult. The usual film has the same facial and irons - and then it does not matter which side to lay it. But in the case of one-sided film, the situation is slightly harder.
For example, antioxidant films from the fabric, and according to the installation requirements, it should look inside the room. Parokone films need to be putting a smooth side to the insulation, rough - out. But with diffusion films should be viewed directly into the instructions, as such films can be both one-sided and double-sided. Energy-saving films are fitted with a foil side, on the contrary, outward - after all, they must reflect, and not absorb heat. The same applies to metal coatings.
This information should be specified in the instructions or on the manufacturer's website, you can ask about this consultant or master. However, if nothing from the above is suitable for you, you will have to learn how to determine the parties of vaporizolation yourself.
So, remember: if vaporizolation is two-color sides, the light side will always be laid down to the insulation.
But also pay attention to how the pair polypoletor roll rolls - the side that is addressed to the floor will be internal, and should be put on the insulation. In the case of a vapor polypoletor with a different surface, a smooth layer will always be internal, and a dusty or grungy - outdoor.
It is believed that this is a mandatory point - it is categorically impossible that the wall comes into contact with the membrane close, you should leave a clearance for ventilation of about five centimeters. Condensate will not accumulate in this way. In the case of a diffusion vapor polypoletor, the air layer is made with the outside, and the film itself is placed directly on the insulation.
