Like all steam insulating coatings, the membrane canvas of the izovek on one side has a smooth coating, and with another darous.

Water pairs are picked up with villings and in the dosage volume are displayed on the opposite side, where its evaporation occurs. The glossy base in a considerable extent contributes to this.

The material is produced by several species denoted by the literals:

Each model has individual characteristics. This is enough to choose the best option for a specific case: wall insulation, ceiling, moisture protection, wind.

With the protection scheme of the insulation from the vapor of moisture, which accumulated indoors, from the side of the room smooth side Parosolation falls on Minvatu. From the outside of the Izovek, the insulation lies with a durable surface. I sucks moisture and takes it outwards where her evaporation occurs. The glossy coating in a large extent contributes to this process.

When insulating the house, it is important correctly a party to lay steam barrier to insulation. After all, when violating the norms into the house there will be a cold, and heat inside will not be saved. In our article, we will consider in more detail all the nuances of laying vaporizolation.

4. Rules for fixing vaporizolation

Which side to lay paosoolence to the insulation

Before determining which side you need to lay vaporizolation, it should be considered space for laying a vaporizolation membrane:

• If your insulation will be laid from the facade, then vapor barrier should be fixed outside. So you will make waterproof;
• The space under the attic, for example, the ceiling or overlap requires the laying of the vaporizolation membrane from the bottom of the insulation;
• When processing roofing and ceiling, it is necessary to use antioxidant vapor barrier. Diffusion and bulk coating are in demand. Make them follows from top of mineral wool;
• If your roof and ceiling do not have additional insulation, then in this case, vaporizolation is fixed on rafters from the bottom side;
• With thermal insulation of the floor and walls from the inside, it is necessary to further lay the film of vapor barrier outside Minvati.

Many builders, even those who have extensive experience, do not pay attention to which side to fix the vapor barrier film to the insulation. When choosing vaporizolation film It is better to give preference to the material that the facial and auto side is the same.

But many choose options with different sides, and often with an antioxidant insulator. In this case, it is necessary to know that the tissue surface is point side. It is placed in the inside of the room. Also, the metal plane of the foil membrane should be placed. That is, the brilliant side into the inside of the room.

In independence, it is placed with a rough side to the room, and smooth to the insulation.

When buying diffusion components, you should carefully examine the instructions for use. Different manufacturers produce bilateral and unilateral vapor barrier films.

In most cases, the dark side of the film is outdoor.

What are the vapor insulation membranes

Membranes that are used in construction are:

1. Paramotable.
2. With vapor barrier properties.

When using mineral wool as a heater, an additional layer of vaporizolation is arranged for its protection against moisture from the inside. If the walls are protected outside, there should be no pores or perforations in the components.

When choosing, you need to pay attention to the vapor permeability coefficient. It should be as small as possible. A good option will be the purchase of a conventional polyethylene film. WHERE WHAT WILL BE FIRE, which is additionally reinforced. And if vaporizolation has a foil aluminum coating, then such a film will be high quality and durable. The use of vapor barrier indoors leads to an increase in humidity. Therefore, do not forget about the device of a high-quality ventilation system.

In special films of vaporizolation, atoxidant coating is present. With its help, the moisture is accumulated on insulation. They are often used in those places that are subject to corrosion. For example, in such materials as professional flooring, metal tile and others. The rough water surface helps the output of moisture. The tissue side must be turned outward, so that the distance from 2 to 6 cm is respected to the insulation.

The construction membrane is used to insulate the house outside. It is able to prevent material from bad weather conditions, and performs evaporation. Typically, vaporizolation has small pores and therefore water is removed from the insulation in the ventilation. Thanks to this, the insulation quickly enhances.

There are several types of vapor-permeable films:

1. Diffusion membranes. Parry permeability coefficient can be from 300 to 1000 g / m2.
2. Pseudo diffusion. They miss no more than 300 g / m2 of evaporation during the day.
3. Superdiffusion membranes. The vapor of evaporation is greater than 1000g / m2.

Pseudo diffusion type of vaporizolation is high-quality moisture protection, so it is often laid under the roof as an outer layer. Do not forget about the air layer device. The disadvantage of this type is the poor conductivity of the steam, so such a film is not used for facade processing. Condensate will begin to accumulate on the surface of the insulation, as dust and different garbage will be clogged into the pores of the membrane.

In two other species, the blockage of pores is excluded. Therefore, you can not leave air layer And additionally arrange a crate or counterbuilding.

In the membranes of diffusion films of volumetric execution, a ventilating layer is provided in advance. The device of such a film is very similar to the antioxidant type. The difference is only in the exit of moisture from the insulation. With a slight bias, the roofing condensate will not flip through the bottom.

The need for an air layer device at the membrane

Leave the air layer always. The gap equal to 5 cm is arranged from the bottom side of the film. Thus, you can avoid the appearance of condensate on the floor, walls or insulation. When using a diffusion film, it can be mounted on the moisture-resistant phaneer, OSP or thermal insulation. And the interlayer for ventilation is arranged from the outside. When using an antioxidant component, an air gap 4-6 cm on both sides should be made.

When the roofing device, the roof and the ceiling for the device of the ventilation clearance, you need to install an additional copier from wooden bars. When the device of horizontal racks and profiles, which are perpendicular to the wall and film, should be leaving the gap for the ventilated facade.

Rules for fastening vaporizolation

Attach the film to the walls, the ceiling or semi can with a stapler or nails with a wide hat. But the highest quality option will be the use of counterparts.

Laying the vapor insulation film should be a mustache at least 10 cm. After fastening the vapor barrier, the joints must be sampled with a special ribbon or scotch.

For the qualitative ratio of moisture and temperature of the building structure, as well as for a long service life, membranes will help. Without their participation, such qualities cannot be achieved. When laying vaporizolation, all the rules should be followed. Many manufacturers indicate the packaging recommendations on the installation of vaporizolation.

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 is performed 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:

1. liquid painting vaporizolation;
2. parosolation membranes (film).

Painting vaporizolation is applied using brushes and rollers in those places where roll vapor barrier, for example, on fan and chimnery. 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:

• membranes with vapor insulation properties;
• membranes vapor1mant.

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, floor or indoor space Houses located directly under it, it is recommended to use the appropriate film. Note that insulating layer Located 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 perfect choice There will be a 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. This is about metal tile, professional flooring, galvanovka, 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 in 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:

1. Pseudo diffusion membranes that transmit no more than 300 grams / m2 of evaporation for 24 hours.
2. Diffusion membranes, with parry permeability coefficient within 300-1000 grams / m2.
3. Superdiffusional membranes, with an indicator of evaporation of more than 1000 grams / m2.

Since the first type of isolation is considered good protection against moisture effects, it is often located under the surface of the roof as 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.

• If the insulation is stacked from the front part of the wall, the vapor barrier film is fixed from the outer part, it will be hydraulic protection.
• The processing of the ceiling and roof requires the use of antioxidant vaporizolation. Frequently applied volumetric and diffusion coatings. They are stacked on top of Minvati on the principle of Ventfasada's organization.
• In the absence of additional insulation of the roof and ceiling, the vapor barrier film is attached from the bottom side of the rafter.
• The thermal insulation of the top of the overlap of the rooms, the ceiling, located under the attic space, requires the laying of a vapor insulation membrane from the bottom side of the insulation.
• By performing thermal insulation of walls and floor inside, it is recommended to additionally lay the vapor barrier film from the outdoor side of Minvata.

Many "experienced" builders even have no idea how to attach parosolation membrane On the walls: facial 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

Fixation of the membrane to walls, semi or ceiling can be carried out by nails with a wide hat or 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 the membranes will allow any construction design to be veneer long term. 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, the correct sequence of actions should be carefully complicated and only the most best Materials. Unfortunately, often the owners who take their home independently, forget about one very an important aspect - About the vapor insulator. 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's why an important stage Insulation is the fastening of a "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.

• Film. A deaf parobarrier who does not miss the water vapor. One of the main advantages - low price. As a rule, made of polyethylene or butylene, their derivatives. Two-layer paroconsetable films with a smooth inner and rough outer surface. Lingering on the outside, the droplets of the condensate do not flow down, and over time evaporate. In the case of a deaf parobararier, you also need to take care of the air layer, in order to avoid the occurrence of the greenhouse effect, but about it a little later.
• Diffusion membrane. The main difference from the film is that the membrane passes part of the pair through itself - but only the optimal amount that is not delayed inside and instantly evaporates. Therefore, the vapor permeability of the membrane is considered limited. The diffusion membrane is made of polymer film and polypropylene, has two sides.
• Reflective or energy-saving film. The outer layer of such a film is metallized, which allows it to withstand high temperatures. Therefore, it is most often used in baths or saunas, reflecting part of infrared radiation.

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. He falls like on external surfacesand 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 interior, vaporizolation and waterproofing are required to avoid the formation of fungus, mold and wetting walls.

Device

Acquisition of set qualitative 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 spend preparatory 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 Mandatory should be treated with the compositions 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. Best use here diffusion membrane.

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 flat roof or concrete ceiling From the inside, you can also use the usual vapor barrier film. 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, you should pay special attention On possible gaps arising from the difference in the width of the insulation, frame and vaporizolator. 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 They are stacked by a foil side, on the contrary, out - 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 insulation with different surface The 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 a nail with a wide hat, but the best option is considered to be countered.

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.

Heating roof or room with thermal insulator (mineral wool, glass gamble, loose foam), able to skip and accumulate moisture, it is necessary to mount a vapor insulation layer. The moisture that fell into thermal insulation significantly worsens its operational properties, increasing the thermal conductivity. In addition, due to the wet environment, wooden structures with which the insulation contacts is quickly starting to be rotated and collapsed. At the stage of preparations for the warming of the roof or at home it is important to understand which side to lay vapor barrier to the insulation - the violation of technology will lead to the fact that steam from the room will penetrate into the thermal insulation layer. The membranes used in construction are divided by vapor permeability to completely impenetrable films and partially permeable (diffusion).

Manufacturers offer vapor insulation membranes of the following types:

• polyethylene film (can be used, insulating roofing or floor, vapor and hydraulic barrier);
• reinforced film from polyethylene (distinguished by increased strength);
• follicated with aluminum film (used for internal insulation, mounted on the reflective side to the room - additionally helps to maintain heat, primarily designed for use in saunas and baths);
• the film with an anti-condensate coating (prevents moisture condensation is intended for installation in the composition of structures with metal elements, prone to corrosion - professional flooring, metal tile, etc., the film treated with the heat insulator is mounted).

Polyethylene reinforced film

If, when insulation of rooms in the house, a completely impenetrable film is used to create a parobacker, it is necessary to provide effective ventilation of premises capable of output excess moisture.
Parosolation films with porous structure differ in diffusion ability. Due to the pores in the moisture barrier from the insulation goes outward, thanks to which the thermal insulator retains its operational properties, and in contact with it metal constructions Do not rust, wooden - do not rot. Among the vapor-permeable membranes differ:
Pseudodiffusional. During the day, up to 300 gr / m2 of evaporation are passed.
Diffusion. The number of transmitted evaporation per day is from 300 to 1000 gr / m2.
Superdiffusion. The evaporation rate exceeds 1000 gr / m2.
The vapor barrier film of the first type refers to efficient moisture protection and is used for internal structures (space side). If the pseudodiffusion membrane can be mounted on top of the fibrous heat insulator on outdoor wallThe parobararier will delay moisture in the insulation. For facade insulation, diffusion and superdiffusion membranes are suitable, which simultaneously serve as a windarrier.

Principles of installation of a vapor barrier

Laying vaporizolation is an important stage of work on the insulation of structures with fibrous materials capable of accumulating moisture. Work is conducted as part of the repair or reconstruction of the house or at the preparation for finishing new buildings. It is necessary to know how to properly fasten the membrane web between themselves to provide a solid layer that protects moisture on the penetration of moisture, how to fix the film to the designs. Before laying a vapor barrier film, it is also necessary to determine which side it is required to be located to the warming material.

Preparatory stage

For the insulation of a block or wooden house, the bath arrangement, thermal insulation materials that need to protect against the accumulation of moisture are used. For this purpose, on the walls inside the house, on the ceiling or floor, on inner side Roofing cake mount material that does not pass evaporation. Either the diffusion membrane with facade insulation.
At the preparatory stage, you should choose a variant of vaporizolation, taking into account the features of installation and requirements for the characteristics of the film. The number of popular options includes the "Izospan" (and its analogue "Megazol") - a membrane material with high operating parameters. The manufacturer offers a line of membranes with various technical indicators, which allows you to choose the material depending on the purpose - vapor barrier for the roof, overlap, wall structures From wood or concrete.
Those who plan to build a bath, not without reason, believe that the foil film reliably will save the mineral wet insulation from wetting and will help maintain a high temperature in the room due to the reflection of thermal radiation. Along with the classic scheme "Insulation + vaporizolation barrier" today used ready-made non-combustible heat insulating mats With a foil-posed surface.

Correctly reflective vaporizoation

Before laying vaporizolation, it is necessary to competently prepare the surfaces of the structures. The preparation technology depends on the material from which walls, gender, ceiling or roof are made. It is also taken into account, what works are carried out at the facility - construction or repair:
When erecting a wooden house, all elements of wood structures should be treated against rotting, damage to pests and ignition.
In the course repair work Pre-perform dismantling finishes, clean the surfaces, while:
Wooden designs are treated with antiseptic and flame.
Concrete and block structures are treated with an antiseptic if they are reckled and there is a risk of mold appearance, as well as in wet rooms.
Due to the incorrect preparation of wall structures, overlapping, or a rafter system can eventually come into disrepair or to become a source of a rift of fungus capable of provoking allergies, an asthma attack, aggravation of respiratory diseases.

How to lay vapor insulation on the ceiling

Installation of a vapor barrier layer on the ceiling is required when insulating a flat or single-sided roof in a house without a attic, with the heat insulation of the basement, as well as residential premises above which is located cold attic. It is also insulating and steam insulated ceiling in the bath. Before laying vaporizion on the roof from concrete slabon reinforced concrete or wooden overlap From the inside, the design surface should be prepared.
The canvas from the film or the pseudodiffusion membrane must be solid so that there are no joints through which the moisture can penetrate the insulation. If width rolled material Lacks, the bands will have to be allowed to be kept together. The recommended leaflet is from 10 to 20 cm, while the joints on both sides are neatly sampled by reinforced construction tape.

Fastening a vapor insulating membrane

The canvas from the foil film are stacked without an adhesion - jack, and the seam is punctured by aluminum scotch.
If the base of the roof or overlap is a wooden structure, you first need to put a waterproofing membrane (solid canvas) and attach it to the base (you can use vapor barrier material).
Then, the heat insulator is placed in the form of mats or rolled material from mineral (basalt) wool between the lags of the overlap or rafters. After that, you can retain vapor insulation on the ceiling. If the thickness of the thermal insulator corresponds to the thickness of the lag, you should navigate the counterclaim from the plants to create a ventilation gap.
Putting vaporizion on the ceiling should be so that the canvas around the perimeter goes to the walls and that all the angles are closed. The joints of the canvases should have to the lags of overlappings - this will reliably fix them. To qualitatively to put vapor barrier on the ceiling, follow the tension of the web, it should not be saved.

Laying on the ceiling

We will also consider how to lay vaporizoation on concrete overlap. To inside insulate the ceiling or flat roofmade from concrete slab, it is required to attach to it waterproofing (vapor barrier film) with the help of self-adhesive tape, and then mount the crate of bars or metal profile.
The correct height of the cage should be seamless, taking into account the thickness of the insulation and the ventilation gap, the installation step is 1-2 cm less than the width of the insulation, so that mats from insulation materials are in the cells of the Merze. How to mount vaporizolation to the crate will be described in detail below.

How to lay vapor insulation on the floor

Installation of a vaporizolation membrane on the floor by technology is similar to how vapor barrier is performed for the walls and the ceiling. After preparing the base of the wooden floor when warming on lags, before laying vapor barrier to the floor, a waterproofing carpet is mounted, which should be lagged. Then the heat insulator made of mineral wool is inserted between the lags. After that, the laying of vaporizolation is performed, while it is important to know how to properly drain the film.
The nestrest of the rolled material should be at least 10 cm, while on each side of the joint is glued with scotch. The resulting canvas are fixed in such a way that the adhesions lie on the lags of the floor, and throughout the perimeter, evenly stretched canvas came to the walls by 5-10 cm.

Insulated floor with air gap

Before laying vaporizoation to the concrete floor, you need to install the crate, between the elements of which the Muspiece will go to the waterproofing and insulation. Further, work is carried out according to the standard scheme.

Fastening principles

If insulating concrete structures or wooden walls, It is necessary to install a lattice from bars. To the resulting crate, to the ceiling or slinge system The film is conveniently attached using a bracket and a construction stapler. You can also fix the vapor barrier material with nails with wide hats or linings under the Hats. It is advisable to use galvanized nails - they do not rust. The concrete structures of the film and the membrane are put with a special connective tape.

Fall when installing vaporizolation

To properly mount vaporizolation, the web should be accurately stretched, and the fastening elements are located with a small step - no more than 30 cm. Mounting rules are prescribed carefully to attract the canvases around the perimeter - it is steel and fixed to eliminate the possibility of moisture penetration into the insulation.
Before performing the fixation of vapor barrier, make sure that the canvas is located the right side to the heat insulation.
Which side to install vapor insulation material

Consider which side to the insulation the film or membrane is stacked:

• polyethylene film (simple or reinforced) can be attached to any party - this does not affect the functionality of the barrier;
• the foil film is placed brilliant side towards the room so that the barrier reflects heat;
• the anti-condensate film is fixed by the processed side to structures, fabric to the room;
• the membrane must be addressed by a smooth side to heat insulating material, and scabbing towards the room.

The rule of laying vaporizoation to insulation

If the front side of the membrane looks like an invalid, and it is difficult to determine how to put the material correctly, you can conduct an experiment. A small piece of membranes cover the bowl with boiling water - which side will appear condensate, that side and waterproof, it must be addressed to the insulation.
It is important to know which side to lay vapor barrier to the insulation, if the membrane is used to mount the waterproofing barrier - facial or irons. Heat insulating "Pie" with internal insulation It is mounted in such a way that on both sides to the insulation, the smooth side of the membrane was drawn. That is, the grungy layer of vaporizolation should be facing the room, and when installing the waterproofing carpet - in the direction of the structure that is insulated.

FEATURES OF MONTAGE

It is important not only to correctly lay vaporizolation, but also to ensure the ventilation gap between the steamproof layer and the construction of the construction under finish finishFor which the crates are stuffed. Moisture, settling on the rough side of laid vapor insulating canvases, will evaporate naturally without damaging the finish.
If vaporizolation is installed correctly, the insulation is reliably protected from moisture. Not half of the problems associated with the freezing and damage to the structures are associated with the shortcomings in the installation of the Parobarmer.

Steam barrier for the walls is the solution to the task of protecting the structure from the direct action of water vapor. Couples can worsen the characteristics of many building materials. It provokes the appearance, reduces the life of structures. Therefore, laying vaporizolation is an extremely important stage of building various objects.

Installation of vaporizolation of walls is especially necessary in rooms, where at the same time there are quite warm temperatures and high humidity. As an example, you can lead, as well as basements that are heated. Within these structures formed couples, that is warm air With small drops of water.

The directions of exit from the room for it are ceilings and walls. Gradually, due to permanent vaporization, the surface of the structures is destroyed, so vaporizolation is the necessary measure during construction.

So why do you need vapor insulation walls in facilities? It is she who creates an obstacle to the penetration of vapors, thereby preventing the destruction of the walls of the object. Parosolation may be required not only in basements and baths, but in many other structures.

Its device is appropriate if the object is insulated outside the material for which the small impact resistance is characteristic. It is worth understanding that there is no universal insulating material, and it is necessary to select vaporizolation according to the object and properties of its structures.

Where vaporizoation is required

There are a number of situations in which you must install vaporizolation.

These include the following:

• Parosolation, especially in those situations when cotton materials are used as thermal insulation. Glasswater and mineral wool have excellent thermal insulating properties and included in the range of materials that are well passed air. Their disadvantage is fear high humidity. Under the action of a liquid or a pair, cotton materials are wedged and lose operational characteristics, and over time and are destroyed at all. Installation of vaporizolation will help to avoid such consequences.
• Multilayer wall structures used in. Frame structures need to provide effective vapor barrier. The order of installation of a vaporizing material in frame house will be discussed in detail below.
• The surface of the outer walls need steamproofing to ensure wind protection. Parizolizing materials make the air flow softer, turn it into a more dosed. This allows you to protect the outer insulating layer of overload. As an example, a brick wall can be brought, which is insulated with a material type material, and then trimmed with a siding coating. Thanks to the parobarnary, a decrease in wall blowing is achieved. Ventilation gap allows you to remove excess moisture from the windproof surface.

An important factor that allows for an acceptable microclimate in any room, except for pairo, and thermal insulation, is a functioning ventilation.

Materials for vapor insulation

Putting vaporizolation is possible using a variety of materials. The very concept of "vaporizolation" does not mean that the barrier must block the circulation of steam at all. Modern vapor barrier membrane provides minimum air flow to prevent the greenhouse effect indoor effect.

The membrane delays the excess moisture, and the air, which was part of the steam, is not distinguished by the ability to damage the walls and heat-insulating materials. Parizolizing materials are able to redirect air flow to the exhaust ventilation system.

On the walls you can lay the following types of vapor barrier materials:

• Polyethylene. Is an traditional material To create a vapor insulating layer. Such vaporizolation to the wall must be fixed with caution, without excess tension. It is important that conditions are not created for the breakthrough of the film when changing the season. It should be understood that in the absence of polyethylene perforation, this material limits the receipt and steam, and air, which forms obstacles to create a comfortable microclimate indoor. However, perforation no longer provides good vaporizoation of insulation material and walls. This variety of vaporizolation is less and less used in modern construction.
• Mastic materials. Such material is applied to the wall, passes the air and delays the excess moisture. Wall processing is carried out before the implementation of finishing finishing manipulations. Mastic materials are relatively inexpensive and easy to use.
• Membrane films. This type of vaporizolation is the most modern. The film passes the air and stops moisture. The material is characterized by correct amount of vapor permeability to ensure the acceptable properties of the insulation. Even wadding insulation materials during the operation of membrane films as vaporizolation are not wedged, retain the ability to normal air exchange and do not lose their own performance characteristics. Membrane vapor insulation materials are conveniently used for isolation of both frame and wooden walls.

When choosing membrane films, there is often no need for air gaps.

Advantages of membrane materials

Membrane films are priority if you need to select a vaporizolizing material. Mastics are in second place according to the degree of efficiency, and polyethylene films in modern construction are used relatively rarely.

The advantages of membrane films compared to the rest of the vaporizolizing materials include:

• high efficiency of operation;
• ease of installation;
• strength;
• good ability to repulsion moisture;
• ensuring the resistance of the surface of the wall to the reproduction of mold microorganisms;
• resistance to rotting processes;
• environmental friendliness;
• long use - film retains initial properties for 50 years;
• wide temperature range of operation (from -60 to +80 degrees Celsius).

Thus, the benefits of choosing exactly the vaporizing membranes are obvious, which determines the increasing popularity of them on construction market.

Varieties of membrane materials

The range of materials for vapor insulation on the modern construction market is very wide. We should consider species of membrane materials that have already deserved their authority among consumers:

• Membranes that can be attached to the outside of thermal insulation (it is an external regards space). These include such brands: "Izosan A", "Megazole SD", "Megazol A". These membranes are used to protect the outer side of the walls of frame structures, bruschers, panel and combined buildings from a variety of atmospheric phenomena: wind, snow, rain.

The membrane should fit tightly to the insulation material, to be reliably fixed on the mounting structure, do not have provisive areas (they provoke cotton with sharp wind gusts).

• Membranes that can be put on the inside of the walls. These include: "Megazol B", "Izospan in". This type of membrane materials protects the walls from fungus, condensate, corrosion of structural elements. Also, such membranes prevent the ingress of particles of the insulation in the space of the structure.
• Membranes, including reflective layer. These include: "Izospan FS", "Izospan FD", "Izospan FX". They are applied to vapor insulation of such premises as saunas and baths.

Select material for vapor barrier is necessary strictly according to the purpose of use. This allows you to create optimal conditions for creating a comfortable climate in the room.

Installation of a vapor insulation film on the walls

Installation of vaporizolation on the walls is used in cases where mineral materials are used as thermal insulation. It is important to comply with the correct order of installation of a vapor barrier film.

It includes the following stages of work:

• Vapor insulation film must be placed necessary side, after which it is gentle and securely secure on the crate. It is necessary to work carefully in order not to damage the film.
• Then you need to smoke the possible gaps, as well as the places of punctures and overstov.
• Next, you need to mount the crate using bars to create acceptable ventilation.
• The design is then covered with plasterboard, wall panels, other finishing materials.

The correct installation of a vapor barrier film will ensure a comfortable microclimate indoor.

It is necessary to understand how to properly lay paosoolence in frame houses. To do this, you must first install the membrane with the required side, then fasten it using a stapler to the racks. Next, it is necessary to smoke the locations of the joints using a special tape or mastic.

When used as an eco-water insulation material, polyurethane foam, foam and under the condition of an effective ventilating system a vapor insulation layer in frame design may not be required.

If the need for vapor barrier is still there, then one of the two possible schemes should be applied:

• The vapor insulation barrier is seamless on the frame racks. How to fix vaporizion in this case? First, the film is fixed on the racks, then the walls are cladding with clapboard, plasterboard or other internal finishing materials. This option It can be used in the buildings used for the purpose of seasonal stay, in which there is no need for the cold season. These include guest buildings, country facilities, workshops. This option involves ensuring efficient ventilation of the structure.
• It assumes the installation of a layer of crate (horizontal or vertical plan) over the membrane. The case is necessary to provide an air gap from 30 to 50 millimeters from the wall surface. This option is advisable to use in homes for permanent stay or buildings involving intensive use in the cold season.

The selection of a warehouse installation scheme in a frame house must be carried out, based on the intended intensity and seasonality of the use of the room.

Steamed walls in wooden houses

Constructions from wooden materials We need special steaming. Wooden houses characterized high rates wall permeability in comparison with brick and stone walls. This indicator is determined by the thickness of the bar and logs, the presence of cracks, the impermeability of grooves for moisture and steam.

The glued timber, which is used to build the walls, should be dried in production to an acceptable humidity indicator. It should also provide for sealing grooves, low shrinkage. All this is necessary for the limited admission of steam into the insulation.

Bruce or log walls With natural indicators of humidity dried directly during use. Due to the destruction for 5 years, strains, cracks appear on the walls. The logs and the timber change their dimensional characteristics, the grooves are losing tightness.

Therefore, for 5 years it is not necessary to exercise interior decoration - It will not allow access to the groove to return tightness. In such a situation, two outputs are envisaged: or wait for a complete drying of the tree, or organize vapor barrier using the Izospan FB type membrane, "Izospan B", "Izospan FS".

A vaporizolizing barrier must form a single contour with the attic and basement floors of the structure.

The study of the characteristics of vaporizolation allows you to deal with the fact that the organization of this construction phase is necessary. Incorrect procedure for events can lead to absence comfortable conditions For accommodation or work indoors.

It is for this reason that the choice and installation of vaporizolizing materials needs to be given a sufficient amount of time during the construction of various kinds of structures.

"Izospan in" (which side to the insulation to lay it, you will learn from the article) is a material that acts as a parobacker when there is a need to protect thermal insulation or other structural elements that can be saturated with moisture pairs during operation. Parobarrier can be used in buildings of any destination. In its structure, two layers, one of which is smooth, while the other is grungy. Last layer Allows the material to hold the drops of moisture, which after evaporate.

The need for use

The use of vapor barrier material "ISOSPA B" allows for a long time to maintain the performance of thermal insulation. The material prevents the formation of excess moisture, protecting nodes of buildings from corrosion and lesion by microorganisms. As another additional function of vaporizolation, it acts that it protects the room from penetration into the insulation fibers.

Which side to be stuck

Quite often, "Izospan b" is recently used as vaporizolation. Which side to the insulation to lay it, you must ask before the start of installation. At the first stage, the consumer should determine where the smooth and rough surface is located. According to the instructions, the smooth side must be addressed to the surface of the insulation, this advice must be followed strictly. The membrane is installed on bearing elements Frame or black trim. Use a stapler as a fastener.

If the room will have finishing material in or lining, then "Izospan in" is strengthened by frame wooden rails With a cross section of 4x5 cm. Installation works provide a dense docking of thermal insulation with a film. If the material is used as the horizontal bands should be laid by the bill, and start these work is necessary below. Horizontally and vertical overlaps should be about 15 cm.

Used to carry out internal work "Izospan B" material. Which side to the insulation to lay it, you are now known. However, when installing, there are many nuances that must be observed. For example, vaporizolation can be used when the ceiling device. At the same time, the canvas should be laid on ceiling lags. The material is necessary between the draft floor and finishing between thermal insulation and top layer Membranes, as well as between the membrane and the final floor, leaving the gap within up to 5 cm.

If you also decided to use when repairing "Izospan in", which side to the insulation it is necessary to have it, it is important to ask even until the start of manipulations. For example, if working surface Presented by plasterboard, the membrane must be fixed to the galvanized profile. It should be tightly mounted a smooth side to thermal insulation. All the resulting joints and places where the membrane will be connected to other materials, it is necessary to sample the connective tape of the same manufacturer. We should not forget to leave the ventilation gap of 3 cm, which is necessary to exclude the offset and reduce the likelihood of accumulation of extra moisture.

Quite often, people ask the question of which side to have vapor barrier to the insulation, if the latter is strengthened from the outside of the wall. In this case, "Izospan B" should be installed indoors, and its rough part must be addressed inside. To fasten the material in all cases, you can use stapler or rails, the last of which are nails are nailed. Both solutions are good, the main thing at the same time is to purchase galvanized fasteners, which will serve for a long time and will not cause rusty spots.

Education overhead

After you have dealt with which side to lay the "isospan" to the insulation, you need to pay attention to another moment, which is the need for an overlap of 20 cm wide between the canvas, which will exclude air penetration under the material. If fixation is carried out to vertical profiles, then the material should be pulled to prevent its sagging. A little hope is possible, but its oscillations should not exceed 50 mm.

Specifications

It is quite common today vapor barrier "Izospan". Which side to the insulation to lay it was mentioned above. However, you can also be interested in specifications, as well as purpose. For example, the areas of use in this case are as follows:

• insulated inclined roofs;
• internal walls;
• frame walls;
• complete overlaps.

The material of the width that can be equal to 1.4 or 1.6 m is available. The area of \u200b\u200bone roll is 35 or 70 m 2. The composition contains one hundred percent polypropylene, its discontinuous load (transverse and longitudinal) is 107 and 130 N / cm, respectively. Resistance to patch permeability per square meter is 7 pa / mg. The waterproofness of the material is 1000 mm of water. Art. For 4 months, the surface of "Isyospan B" will be able to undergo impact ultraviolet radiation. It is possible to operate it in temperature range in the range from -60 to +80 ° C.

Technology for performing vapor insulation works

If you also decided to use "Izospan in" which side to the insulation to lay it, it is necessary to decide before the start of work. More details about this was described above. However, not only correct location Material in relation to thermal insulation is a guarantee of a successful procedure. It is important to comply with all the rules of technology. Thus, it should be borne in mind that a vaporizolation coating is stacked according to the principle that is used when installing the waterproofing layer. The coating should be placed entirely, the ruptures should be minimal. In those places where the coating is adjacent to the wall, it is important to start it on vertical surface Approximately 15 cm to eliminate the hydration of thermal insulation. Parosolation either should not be moisturized during work.

Related fabrics must be laid by the camist, while it is important to exclude the formation of voids and holes. Most more common today becomes "Izospan B". Which side to the insulation to lay it, it is important to understand for yourself. But it is necessary to remember that in winter such works should be carried out in warm places. The surface where vaporizolation will be stacked, it is necessary to prepare, clean from pollution, dry and warm up. If the rolls were stored in the cold, then they are pre-kept in heat for at least a day. Do not transfer material on cold with place in place.

Which side to have "Izosan A"

You may be interested in the question of which side to lay "Izosan A" to the insulation. This material located on the outside of the wall or roof, after facing material Walls or roofing. The rough surface should be seamless to thermal insulation, while the smooth is located on the side of the roofing material or outdoor facing walls.

Conclusion

You can vaporize the floors with the help of the material "Izospan". Which side to the insulation in this case stacked the material was mentioned above. With the help of this vaporizolation, you can carry out work inside and outside buildings, the main thing is to figure out what kind of membrane to choose.
