Isospan membrane as a means of reliable protection of insulation from moisture. Technical characteristics of izospan and its features What does izospan look like

Vapor barrier is used to protect various structures from moisture and condensation, as well as steam. Thanks to the use of appropriate materials, it will be possible to extend the durability of the structure and prevent the formation of mildew and mildew. Many manufacturers produce special membrane films for this purpose. So, isospan vapor barrier is very popular.

Specifications and types

Isospan vapor barrier is membrane with increased water resistance, which can be laid in all weather conditions. After vapor barrier, the building structure will last several times longer. At the same time, a comfortable microclimate will remain in the room.

In fact, isospan is not only a steam, but also a waterproofing. Accordingly, the material should be installed on roofs and in saunas. In other words, we are talking about those cases when a higher temperature and high level of humidity are required in the room. Although such a membrane is quite expensive, it will become a truly indispensable element.

There are many types of vapor barrier on sale, which have their own advantages and features.

• Izospan A - vapor-permeable membrane protecting walls, roofs, facades and ceilings from condensation. At the same time, evaporation occurs inside the "cake", so that water will not damage the structure itself.
• Izospan V is a two-layer universal vapor barrier, which is usually used only indoors. With the help of such material, you can protect the roof, walls, basement and attic. Izospan B can be used as a heater. This is due to the fact that the material has a high density.
• Izospan S is a two-layer membrane with hydro-vapor barrier characteristics... Such material is laid in attics, as well as on non-insulated roofs.
• Izospan D - a membrane that provides reliable vapor barrier any building structures. The material is used in the construction of concrete foundations, plinths and floors.
• Izospan AM is a high-strength material made of membrane film... Its feature is protection against mechanical damage. It is customary to lay the material directly on the heat insulator, which will protect it from steam and condensation.

Other varieties

On sale you can find less common types of vapor barrier.

Instructions for the use of isospan

When using this material, the specific modification must be considered. If we talk about Isospane B, then with its help walls, roofs and ceilings are insulated. As a rule, the film is laid on top of the insulation. In this case, it is necessary to adhere to a certain sequence:

Thanks to such a vapor barrier, you will be able to avoid the penetration of moisture or insulation particles into the room.

Izospan S differs significantly from other vapor barrier materials the possibility of using in the construction of roofs with a slope of less than 35˚... Thanks to this vapor barrier, an optimal microclimate is maintained in unheated attics. There is no condensation on the walls and ceilings of the basement floors, which means there is no mold or unpleasant odor.

This modification is laid as follows:

If the roof slope is small, the modification is laid on the boardwalk, fixed to the rafters.

General instructions for self-installation of the vapor barrier

Izospan is a film coating used for insulation purposes. It is necessary so that the thermal insulation retains all its key parameters throughout its service life. Thermal insulation materials actually provide protection for the home, retain heat in inclement weather and provide comfort in the summer heat. It is 100% polypropylene.

Even at the construction stages, you can form a barrier, designed to ensure the preservation of heat, using Izospan in the arrangement of a vapor barrier. There are several types of this material. The film is presented in a large assortment and differs in its purpose. Vapor barrier films and membranes are capable of completely or partially allowing moisture and air to pass through from one side. Some modifications are used to enhance the characteristics of the base materials.

What are the characteristics of Izospan:

For Izospan, various fields of application are envisaged. The main area is still construction. The material has:

• unique structure;
• own labeling;
• individual specifications.

Manufacturers use letter designations for various Izospan modifications. Sometimes these indices are combined in a number of models, due to which a variety in terms of installation and scope of application of Izospan is formed.

Model A

Izospan, And the technical characteristics are as follows.

First, by analogy with a check valve, the membrane easily allows water vapor from the insulation to pass through. Thus, natural ventilation is ensured. On the other hand, Izospan of this type is able to block the penetration of moisture from the outside and prevents condensation from forming. The structure of the insulation remains unchanged, even if there is a strong wind outside.

On the outside, Izospan is equipped with a layer of waterproof material. For this reason, it is often used in the construction of roof structures. It also finds application as a protection for walls and ventilated facades. Due to the properties of waterproofing, which is characteristic of Izospan, its membranes increase the service life of thermal insulation. Even the best insulation sooner or later collapses due to the influence of the wind. Izospan, A is ideal for outdoor protection of the home.

The membrane must be laid on the outside, on top of the insulation. That is, its smooth side should look out into the street, which can be quite easily identified by touch. The roll is divided into wide strips of suitable size. Following these, it is carefully spread overlapping with the next layer over the entire area.

Roof vapor barrier

Arrangement of hydro and vapor barrier of the roof starts from the bottom. Laying out the membrane material, do not allow contact with the thermal insulation. This will reduce the ability to resist moisture. To understand what we are talking about, it is enough to imagine the following situation. Let's say a person went on a hike. He took with him a canvas tent, which was used in Soviet times. If, during the rain, you run your finger across the roof while inside, then after a few minutes it will begin to drip from this area. Izospan works in a similar way. It is always equipped with a double crate.

Izospan is equipped outside, laying on a crate of slats. The membrane structure increases the degree of insulation. At the same time, it contributes to an increased service life of the structure as a whole. It is very important not to allow all kinds of swelling and sagging during the operation of the roof. Otherwise, you will have to listen to the sounds of the wind with characteristic sounds when the membrane knocks on the roof. The use of thin slats is enough to secure Izospan, leaving 3 cm to the insulation.

Thus, the previous type of Izospan is able to protect from the wind... In addition, it acts as a reliable hydro-barrier for the insulation material. But it doesn't solve the condensation problem. It must be prevented from entering through the membrane in the form of vapor. If the thermal insulation is saturated with moisture by at least 5%, the thermal insulation performance of such a roof will drop by 2 times. In the future, the condensate will get on the metal tile. The roof will turn into a kind of colander.

Technical characteristics Izospan B has the following:

• ability to resist condensation;
• excellent waterproofing properties;
• vapor barrier effect.

Carrying out the installation of various materials when arranging the roof, you need to understand that even the highest-quality insulation for the roof at a certain moment is saturated with water vapor.

Izospan B forms a barrier to internal steam. Its structure consists of two layers:

• the first has a smooth surface and is adjacent to the insulation during installation;
• the second, fuzzy to the touch, absorbs condensation.

Installation of the cover is carried out in all cases with the fleecy side down. There must be a gap between Izospan and the finishing materials so that air can circulate freely in the space. It also prevents moisture build-up. Izospan B is overlapped. At the same time, a grip of 10 cm from the side of the insulation is observed, at least. Fix it with a construction stapler.

Izospan C

There are two layers in its structure: smooth and fleecy. The latter is responsible for keeping condensate. In the future, it erodes. Modification, A forms a vapor barrier for the insulation, preventing the absorption of vapors of water particles formed in the room. The material is used for:

• building walls;
• installation of inclined and insulated roofs;
• arrangement of interfloor ceilings.

In various cement screeds, steam and waterproofing is installed, and Izospan C is also used for laying flat roofs. Thus, in terms of characteristics and structure, this material is in many ways similar to Izospan D. At the same time, it has an increased safety margin. Accordingly, thanks to it, you can get a very dense panel with increased reliability indicators. ... At the same time, Izospan C is about 60% more expensive..

Specifications:

• withstands the temperature range from - 60 to + 80 degrees Celsius;
• impervious to steam;
• has the ability to resist water. This figure is 1 thousand mm of water column.

Izospan C is sometimes used for arranging concrete floors.... It is laid with the smooth side down. It is used for laying horizontal timber floors and similar structures in the attic. In the latter case, the vapor barrier is spread over the insulation.

On inclined roofs, the sheet is laid from bottom to top. The material is overlapped by 15 cm. To avoid depressurization, the joints are glued with adhesive tape on 2 sides, by analogy with double-sided tape. To fix the structures, slats with a diameter of 5 cm are used. The gap between the vapor barrier and the tiled roof should be at least 5 cm.

Izospan is spread over the insulation. A special 50 mm diameter gap must be provided to ensure ventilation. We are talking about the distance between the thermal insulation and the panel. When arranging a concrete floor, Izospan C is laid with an overlap. After that, a cement screed is applied to the canvas. Only after this is the floor covering installed.

​

Izospan D

Suitable for the construction of various types of structures... Able to withstand moderate mechanical stress well. At the same time, it demonstrates good tear resistance and withstands the effects of wind. In winter, it can cope with loads in the form of snow accumulated on the roof. It is considered one of the most reliable and durable options.

Its characteristics:

• completely impervious to water;
• has high strength;
• has a laminated one-sided polypropylene-based coating.

It can be used for all types of roofing, as it forms a barrier to the formation of condensation. It is used for various buildings and structures in order to form a hydro and vapor barrier. It is able to withstand to a large extent negative weather events. It is often used on construction sites to temporarily cover roofs. It can play the role of a protective wall in projects under construction. Such a roof can last up to 4 months. Izospan D is popular when arranging concrete floors that need a waterproofing layer, protecting from moisture from the ground.

Thus, it is used by:

• to protect wooden structures if an insulated roof was used;
• as protection against condensate forming under the roof;
• when arranging a basement;
• during the installation of concrete floors;
• for protection from adverse weather conditions.

If it is necessary to protect the interior of the house from the effects of vapors resulting from vital activity, and to extend the life of the insulation, then it is better to use Izospan D. It can be spread immediately on the rafters, having previously insulated the surface of the pitched roof. The layers of material in this case are the same, and therefore it is possible not to understand which side of the insulation to lay Izospan on.

Installation is carried out in a horizontal orientation., overlap. The material is cut into sheets of the required size. Work begins from the bottom. In the process of laying, bayonets are glued with tape. Surfaces that have adhesive properties on both sides connect two sheets of hydro and vapor barrier between them. Izospan is fixed to the rafters with construction staplers or wooden slats.

The process of choosing wind, hydro and steam protection should be carried out with special care, since among a large number of manufacturers, it is necessary to select the material that turns out to be the most reliable. The membrane of the Izospan company has established itself as a high-quality product, the strength of which has been tested over the years. Let's talk about the peculiarities and intricacies of the Izospan membrane installation further.

How to lay Izospan: features of membrane installation

When answering the question of which side to lay "Izospan", one should be extremely careful, since improper laying of the material will lead to a violation of the integrity of the waterproofing system.

On the one hand, the membrane has a layer that allows air to pass through, thereby eliminating condensation, while the other side is not able to allow moisture or wind to pass through.

We suggest that you familiarize yourself with the recommendations for the installation of Izospan AS and AM membranes. They are used to provide wind and moisture protection to roofing trims. The material is fastened directly to the thermal insulation materials, while the ventilation gap should not be observed. The smooth blue side of the material should be on the outside of the roof.

These types of membranes provide reliable protection of the building from precipitation, wind or defects in roofing. In addition, with the help of the membrane, the removal of moisture through the surface of the insulation is improved.

These membranes are not used as basic or additional roofing materials.

If the membrane is installed on an insulated roof, then the insulation is cut and rolled directly onto it. It is better to start the installation from the bottom of the roof. The minimum overlap is 150 mm. A construction stapler is used to fix the stretched material on the surface of the rafters.

Further, antiseptic wooden counter-rails are attached to the material. Their fixation is carried out using nails or self-tapping screws. The vertical overlap or joint of two parts of the membrane is pressed with a counter-rail. In addition, lathing is mounted on them for further roof finishing. There should be a ventilation gap between the outer part of the membrane and the roof covering to help drain condensate out of the roof space. In addition, you need to worry about arranging the ventilation gap in the ridge part.

The membrane is fixed in a taut position, with the help of the lower edge a lower drain of condensate is provided, which enters the drainage system.

Installation of Izospan A, AF membranes is carried out with a ventilation gap of 4-5 cm, over the insulation, rafters or lathing.

If materials are laid on an insulated roof, then rolling and cutting of the material is performed on the rafters. Installation is carried out by laying overlapping horizontal canvases, while their smooth side should be outside. The minimum overlap is 150 mm.

To fix the canvases, counter-rails are also used, which are fixed with nails or self-tapping screws. The minimum sagging of the membrane is 2 cm. The material should not come into contact with insulation or solid wood areas, as this negatively affects its functional activity.

Application of "Izospan" video:

Any modern building needs high-quality wind and vapor barrier, which is provided by Izospan A - a non-woven building material produced in rolls and intended for insulation of walls and roofs of buildings.

Izospan A - scope and technical characteristics

Izospan A film and other similar materials are very popular today in the construction market. They are useful for creating a barrier layer during the installation of insulation, due to which the probability of moisture getting on the thermal insulation of the object is completely excluded. Modern membrane materials are made from pure polypropylene that does not absorb water, therefore they can be used for insulating objects for various purposes, from standard one-story houses and cottages to non-residential buildings and outbuildings.

The widespread use of Izospan A film is explained by the presence of a number of important advantages in it. The advantages of such insulating materials include:

• strength;
• environmental friendliness;
• high elasticity;
• heat reflection;
• wind protection;
• protection from ultraviolet rays;
• resistance to negative external influences;
• maintenance of performance for several decades.

Due to their technical characteristics, Izospan films are able to reliably protect wood from rotting, and metal from corrosion, to prevent the occurrence of condensation, to reflect air flows, to maintain a stable temperature in the building without releasing heat. Insulating materials are of the greatest importance in the construction of residential buildings, which are especially prone to the formation of cold bridges - houses with attics, cottages with attached garages or other types of outbuildings in harsh domestic climatic conditions.

Insulation types - what is the difference between AF and FB?

The modern building materials market offers owners a huge range of protective and insulating films of all types and grades. Experts identify the following types of windproof, vapor barrier films:

1. 1. Standard. Prevents the formation of condensation on insulation materials, as well as on individual structural elements of the building - roof, walls, etc.
2. 2. Membrane. Not only protects the elements of the object from condensation, but also helps to remove excess moisture from the interior of the house.
3. 3. Foil. A metallized or aluminum-coated film that acts as a vapor and heat insulation, and also has reflective properties.
4. 4. Roofing. Differs in the highest strength, resistance to temperature extremes and adverse environmental influences.

Izospan is a large domestic manufacturer of insulation, which can be used to provide reliable protection to any building from external threats. There are many products under the Izospan brand on the market, the most popular among which are the following:

Installation of Izospan A film - how to install insulation protection?

To install the purchased film, you should strictly follow the instructions from the manufacturer, which takes into account the basic properties of Izospan materials and their characteristics. The insulation installation process does not present any particular difficulties. You can do such work with your own hands, without asking for help from professional installers. However, the performer must take into account all the features of the purchased membrane. Any mistake can lead to the loss of the technical properties of the film, which means that you will have to re-purchase the insulation and carry out its installation.

The whole process of installing insulation materials can be divided into several main stages. At the very beginning, install Izospan A or other insulation on the rough sheathing. The smooth side of the insulation must be in contact with the insulation. Film panels should be laid horizontally from bottom to top and always overlap, both along horizontal and vertical joints. The width of the overlap should be about 15 cm. The individual panels of the material are fastened with a stapler. To ensure the complete tightness of the installed protection for the insulation, it is best to use a special tape from the same manufacturer.

On top of the insulating materials along the frame, we install vertical slats with a section of 4x5 cm or metal profiles. Metal profiles are suitable for further external plasterboard finishing, and wooden slats are suitable for cladding or special panels.

The trim is then attached to the building frame. There must be a ventilation gap between the waterproofing film and the lining, due to which moisture will not linger on the insulation. The described procedure is suitable for the installation of Izospan A insulating materials. If a different film was purchased for construction, its installation may have individual characteristics and nuances, non-observance of which can lead to a decrease in the technical and operational characteristics of the installed protective coatings.

Izospan A is a modern insulation, thanks to which you can increase the comfort, coziness and even functionality of your private home. The use of Izospan for finishing the basement and the attic floor can significantly extend the service life of the rafter system, installed wooden coatings and building materials in general. The film creates a stable, favorable microclimate in residential buildings, reliably protects insulation and other elements of the building from the adverse effects of moisture and wind. And most importantly, it is really easy to work with the most reliable and expensive films. Any owner, using the instructions, will not only provide his home with protection from external factors, but also save money.

Izospan is a film-type insulating material. It ensures the preservation of the original qualities of thermal insulation and is used in a wide variety of areas. Therefore, it is worth considering in detail its advantages and disadvantages, as well as learning how to properly mount the material on the walls, roof, foundation. This and much more will be discussed below.

Types and their properties

Thermal insulation retains heat in the house when it is cold, adds comfort in the heat, and prevents the rooms from being blown out. However, the insulating material itself needs protection from negative atmospheric phenomena. Such protection is provided by a polypropylene membrane - Izospan.

Such a sheet will successfully play the role of protection for thermal insulation. Despite its simplicity, this film material has differences: type A, type B, type C, type F, others. Each type has differences in technical characteristics.

The film complies with the construction GOST and has the following generalized qualities, which are confirmed by the manufacturer:

• thermal conductivity;
• density;
• waterproofness;
• elasticity;
• resistance to negative influences;
• resistance to ultraviolet light;
• environmental Safety;
• Fire safety.

Izospan's properties correspond to the product classification. Classification is the letter indices used by manufacturers to designate the material being produced. Sometimes on sold samples you can see a combination of letter indices. Each new designation expands the possibilities of using the material. The performance characteristics of any Izospan are high.

The material is widespread in the construction field. It is used for vapor barrier both residential and industrial buildings. Izospan's properties comply with sanitary and epidemiological standards. The material is supplied with fire safety certificates and technical certificates.

In the production of Izospan, polypropylene is used. The base is remelted, and then rolled to a certain thickness with special shafts. The material is obtained with a homogeneous structure, dense. The material is considered two-sided, and both surfaces of Izospan perform different functions.

If you lay the vapor barrier correctly, all moisture will remain on the film, it will condense on it. Being on the film, the moisture will evaporate and will not harm the structures.

Today Izospan is recognized as an effective insulation material for attics, garages, walls of private houses.

The properties of the material will protect the metal coating from corrosion, and the wood from decay. The material prevents the penetration of air currents, does not release heat outside. When choosing products, you should focus on the quality of the main modifications, each of which has its own characteristic features.

• Izospan A plays the role of an excellent waterproofing agent. This modification also protects the insulation well from wind and water, thereby increasing its service life. Izospan A is suitable as an insulator for any premises, as it is resistant to mechanical stress, neutral to mold and mildew. The film is stretched longitudinally by 19 cm, and across by 14 cm. The material is used as an additional barrier, fixed to the outer side of the insulation. For fastening the membrane, wooden slats and nails are used.

• Izospan V- an excellent vapor barrier that will exclude high humidity inside the room. Two-layer Izospan B can be used on roofs, internal and external walls, on attic floors. The material is stretched longitudinally by 13 cm, and across by 10.7 cm. Unlike the previous modification, Izospan B is installed inside the insulation, overlapped, taking into account the presence of free space between the layers.
• Izospan S- two-layer, known as a good protection for roofs, frame walls and concrete floors. The membrane is fixed to the insulation, with an overlap, with wooden slats. For insulation, the floor is laid directly on the surface.
• Izospan D- very durable, known as roof protection in terms of waterproofing. In addition to roofs, Izospan D is covered with concrete floors at the level of basement floors. The material is mounted in horizontal strips, fixed with wooden slats. In addition to the main modifications, there are additional varieties of Izospan, the purpose of which should be considered in more detail.

The purpose

The variety of materials in the Izospan line is wide. In addition to basic materials, you can find related products on sale, namely, adhesive tapes and adhesive tapes.

• If connecting ribbon SL fix the strips of hydro- and vapor barrier between themselves, the better impermeability of the connecting seams will be ensured. Installation with connecting tape is carried out at moderate temperature conditions, and the surfaces to be joined must be dry and clean.
• FL tape you can both connect the canvases and repair minor damage. This is a metallized tape with excellent durability. The wear and tear strength of this tape is also high.

• Unilateral scotch ML characterized by high-quality adhesion. Proff modification material has shown itself in especially difficult cases, as it helps in joining uneven surfaces, different bases, for example, brick with concrete, porous surfaces. Izospan ML allows you to glue together plywood, wood and plaster surfaces. The material provides a better abutment of pipes, windows to window openings.
• Izospan KL allows you to glue together two panels. Good sealing of material overlap points. Izospan KL is glued to the upper edge of the insulated panel, paper side up. It is pressed to the lower canvas with a slight movement of the hand at a certain distance from the edge. Then the paper side is removed from the tape and both edges are pressed against each other. Installation of the material is carried out on clean, dry canvases at positive ambient temperatures. The basis of the adhesive layer is water-dispersion modified acrylic. Izospan KL does not contain solvents.

Waterproofing is applied according to the general instructions for ceilings, walls, subfloors.

The works associated with the installation of the membrane are simple and do not require special qualifications.

• Regardless of the place of installation, the smooth surface of the film must always face the thermal insulation. Incorrectly laid canvases will not add effectiveness to insulation, the structure will not receive a vapor barrier effect. Each type of product is accompanied by instructions. Its exact observance will not allow making mistakes in work.

• Lay the material tightly against the surface with a slight overlap in the corners. Place the canvases with an overlap, the size of which should be about 15 cm. If the membrane is attached to the wood components, you can use a furniture or construction stapler. Seal the resulting seams with tape or tape.
• If a reflective film is being mounted, then it must be installed with the metallized side inside the room. Laying must be done without overlap, end-to-end. Glue the joints with adhesive tape.
• If you conduct a vapor barrier on an insulated roof, then lay the film from below. Lay the appropriate blade horizontally, close to the rafters, avoiding wind. Wooden strips treated with an antiseptic 4 x 5 cm wide are suitable as film clips. Such a crate will ensure free evaporation of the condensate.

The general view of the system will be as follows:

• interior decoration;
• Izospan B, C;
• rafters;
• insulation;
• waterproof membrane;
• roof covering.

Vapor barrier of the internal partitions of the house is needed if the interior ceilings are frame.

In this case, Izospan B can be installed on either side of the wall. For work, a stapler or special nails are used. Izospan should be laid horizontally, starting from the bottom. Izospan is fixed with slats, and Izospan A can be mounted on the other side of the wall. General form:

• finishing;
• rail;
• vapor barrier;
• frame;
• insulation;
• moisture protection;
• rail;
• finishing.

Izospan can be used as a vapor barrier for interfloor ceilings.

The material is laid on the rough base of the ceiling with the rough side down. If the membrane is spread on the floor logs, above the insulating layer, then the smooth surface must be laid up. Clearances are required:

1. Between the insulation layer and the vapor barrier layer.
2. Between the flooring and the vapor barrier.
3. Between the ceiling trim and Izospan.

General form:

• ceiling decoration;
• slats;
• vapor barrier;
• rough floor construction;
• beams;
• insulation;
• vapor barrier;
• slats;
• floor finishing.

Like any building material, Izospan has its pros and cons. Let's take a closer look at the technical advantages and disadvantages, as well as consumer reviews.

Pros and cons

The main advantages of the material:

• Lasting. Izospan does not tear during installation, has a long service life.
• Reliable. When laying the material, other materials will remain dry in the worst conditions.
• Universal . The material can be used on any type of structure when installing any insulation.
• Environmentally friendly. The film does not emit harmful substances into the atmosphere.
• Practical.
• Fireproof.
• Convenient to install.

Izospan perfectly weathers the accumulating condensate, significantly improving the characteristics of the insulation. The walls remain dry, so mold and mildew does not appear on them.

Of the disadvantages of Izospan, it is worth noting the need for mandatory treatment of wooden structures with antiseptic agents.

There are other disadvantages as well:

• if the insulation technology is violated, condensation may form at the joints of the material;
• vapor barrier rolls cannot be installed immediately; they must be kept in a warm room;
• the vapor barrier process is impossible if phenomena such as fog or rain are observed;
• when installing Izospan on the concrete surface of the basement, it is recommended to warm up the latter with heat guns.

Consumer reviews of the material are generally positive.

• For example, users write about the qualities of Izospan S that work with him can be carried out simultaneously with the laying of the cake. The material allows you to save on the installation of the lathing. The thermal insulation has been in good condition in two years. No heat loss, no wet spots.

• Another user notes characteristics of Izospan AS... Of the advantages, the high speed of installation is noted. The material also has disadvantages - it is thin, the canvas breaks during fixation to the frame. In addition, with this type of material it is difficult to determine the correct side of the installation, since both of them are smooth.
• In contrast, variant of the FB series easier to define. Users report good roughness on the correct reflective side. However, the material is expensive, since its width is non-standard. Investments pay off in further exploitation.
• Izospan B sides are also easy to spot. The smooth side of the material must be mounted to the insulation. The vapor permeability of the material is at a height, the cost is justified.

Features of use

The sides differ in appearance, to the touch: one is smooth, the other is rough. It is believed that Izospan should be laid with the smooth side to the insulation. The rough side of the film should touch the insulated vertical. The roughness of Izospan effectively absorbs condensation. Without vapor barrier, condensation always flows down to the floor structures. Condensation is harmful to both wood and concrete substrates. Let's consider some special types of Izospan vapor barrier in more detail.

FB series vapor barrier used in interfloor wooden floors, for walls inside a steam room, saunas. The FB series is based on kraft paper and metallized lavsan. Features of structured Izospan allow efficient reflection of thermal energy. It is not necessary to mount the FB series outside, as the material perfectly resists the temperature environment with dry steam up to 140 degrees.

The material has excellent strength characteristics and is environmentally friendly.

The use of Izospan allows to reduce heat losses in the steam room. The same vapor barrier will prevent dampness inside the wall structure.

Dimensions of Izospan FB roll:

• width - 1.2 m;
• length - 35 m.

The material can be used in the temperature range from -60 ... +140 degrees. The technical characteristics of the material correspond to GOST. Performance may be degraded by UV radiation.

Materials of the series FD, FS, FX have similar characteristics. These are vapor-permeable membranes that prevent the weathering of water vapor into the atmosphere. The materials are waterproof, waterproof, and have an energy-saving effect. The materials are capable of reflecting infrared thermal radiation and protect the floors from steam. The use of steam and moisture insulation allows to reduce the period of heating the room, gives significant savings on heating the room.

Izospan AS series it is, at the same time, waterproofing, vapor barrier, interoperability. The membrane has three layers, it protects from wind gusts, moisture from the external environment, insulation, roof elements, walls. Izospan AS series can be mounted on a heater without a ventilation gap. As a result of the application of a series, expenses on the crate between the insulation and Izospan are excluded.

The membrane is diffusion, has shown good water resistance and water resistance. The use of this film has a positive effect on increasing the service life of the entire structure.

The material is produced in rolls 1.6 m wide, 70 m long. The effects of UV radiation, as in the previous version, reduce the quality characteristics of the material. Initial technical qualities are in accordance with GOST.

The AM series membrane has similar characteristics. The material combines the characteristics of water resistance and vapor barrier.

The scope is quite wide:

• insulated sloping roofs;
• frame-type walls;
• walls with external insulation;
• ventilated facade;
• attic floor;
• internal verticals.

Separately, for ventilated facades, a film of the A series with OZD can be used. This vapor-permeable membrane will protect the facade elements from wind and precipitation. The film will not allow the removal of vapors from any type of insulation material. Film width 1.6 m, roll length 70 m.

Separately, as a roof vapor barrier, the material of the RS series can be used. The film is suitable for non-insulated structures. It will protect wooden elements from condensation and penetrating atmospheric agents. As a vapor barrier suitable for flat roof structures.

Another type of film that is suitable for non-insulated roofs is Izospan RM. Three-layer material with reinforced polypropylene mesh. In addition to protecting roof structures, it can be used to protect concrete floors. In this case, it participates as a waterproofing layer.

Which to choose?

If the material is chosen as a vapor barrier for the roof, then such points as are taken into account:

• temperature phenomena at the location of the building;
• the purpose of the roof (operated, unexploited);
• roofing cake construction.

The vapor barrier layer, first of all, must be completely sealed. This quality is very important for such materials. Self-adhesive tape or tape are not in vain recommended for sealing joints.

If a vapor barrier is chosen for a bath, it is desirable to minimize the possibility of fire, therefore FD, FX, FL Termo, foil vapor barrier are the most suitable options for such structures.

It is important to take into account that the bottom layer of the roofing cake must be non-combustible. The incombustibility of the roof for the bathhouse will be increased if the vapor barrier film is laid so that its edges extend beyond the insulation. Experts advise to glue the membrane to the wall and additionally fix it with galvanized strips.

Unlike roofing material and glassine, Izospan is a modern new generation material. Diffusion film has lower vapor permeability values ​​in comparison with the membrane considered in this article: it can be used for both hard and soft roofs.

Diffusion membranes usually consist of several layers. The product combines polypropylene fabric and polyethylene laminate. The cost of this type of vapor barrier is quite high.

However, other analogs have advantages and disadvantages. For example, types such as roofing felt and glassine, have a low cost. However, today few people will use roofing material for vapor barrier of the roof of a residential building. This is a material for household purposes. Glassine is also not used as the main hydro and vapor barrier.

The utilization rate of bituminous membranes is also low. With the help of this material, concrete roofs are vaporized. This type is mounted by heating and then gluing to the base. The main drawback of the material is its heavy weight.

Almost all of the above types of materials are combined by Izospan, which is presented on the market in 14 varieties. Only A class Izospan combines several options for films, for example, AS, AM, with different strength, density and steam transmission ability.

RS series Izospan is a unique, versatile product that will completely replace all materials in the aggregate. The material is indispensable in many construction areas, as it has increased strength, does not harm the interior decoration. Sealing reinforcing mesh made of polypropylene will prevent the formation of harmful fungi and mold, as it creates an additional protective layer for both the material and structures.

Length, thickness, weight, number of meters per roll varies depending on the class of material. The division looks like this.

Laying method

1. It is necessary to lay any vapor barrier on any type of roof after installing the insulation. It can be placed under corrugated board.
2. Waterproofing can be laid in any direction.
3. If the material is laid along the rafters, the overlap should be directly at the level of the rafters. At the same points of contact, the material must be carefully fixed.
4. In places of contact with water pipes that may pass through the roof, the membrane is rolled down, wrapped around the pipes and carefully taped.
5. Some types of materials require a mandatory air gap. Thin wood planks are sufficient to create this space. They are located at a distance of about 50 cm from each other.

The general rules for installing the film assume strict adherence to the instructions for use. The technology of laying on vertical and inclined surfaces should be done from top to bottom. Lay the film strips horizontally correctly. It is necessary to lay the film with an overlap of at least 15 cm. For reliability, glue the joints with adhesive tape. If the wall is finished with plasterboard, the film must be laid with the rough side to the drywall, and the smooth side to the insulation.

• When laying the vapor barrier on the roof Izospan can be fixed directly to the rafters. Bars or thin clamping strips are suitable for fixing. Finishing: plasterboard, plywood, lining, etc., mounted on top of the vapor barrier. If bars were used for fixing, then the trim can be mounted directly on them. A gap forms between the film and the finish. The ventilation gap will ensure better drying of condensate.
• If Izospan used for wall insulation indoors, then first you need to fix the bars on the vertical. If drywall is used as a finishing cladding, then a metal frame will do. After that, a heater is mounted: mineral wool or expanded polystyrene. A vapor barrier is attached to the bars with slats or a stapler. The next step is to establish a fine finish.

• If the walls are insulated from the outside, the procedure should be reversed. First you need a lathing made of bars. Then a vapor barrier is attached to this structure. Next comes a heat insulator, and on top of it is a waterproofing film. The final stage will be the installation of the final finish.
• If the vapor barrier is used on a floor, first you need to lay waterproofing between the lags. Then the insulation is mounted. A vapor barrier is mounted on top of the insulation. Bars are suitable for fixing it. Floorboards are installed on top of the vapor barrier.
• When installing the interfloor overlap the previous steps are practically the same. If necessary, the vapor barrier can also be installed on the ceiling from below. Ceiling trim is mounted on top of the vapor barrier.

• ​​​​​​If the vapor barrier is damaged during installation any structural elements, torn places must be repaired. For this, you can use sticky tapes or special glue. The material is very reliable in installation and is more expensive than ordinary plastic wrap. However, the quality characteristics of Izospan significantly exceed those of the film.

The following tips will help you do your job well.

1. When laying any vapor barrier materials, pay attention to the quality of the joints. If they are poorly glued, the ceiling usually sweats, and the efforts from the work done are practically reduced to zero.
2. It is easiest to close up any hole in the membrane with a special tape for gluing with a width of at least 10 cm. A narrower tape will simply come off.
3. Leave folds of material 2-3 cm wide around windows, other openings, especially if the building is new, constructed. In this case, a deformation margin must be provided for.
4. If the vapor barrier membrane is laid around the roof windows, then it must be protected from the inside with a special finish.
5. If the membrane needs to be fixed on a rough surface of brickwork, wood, it is better to use adhesives with an acrylic or rubber base.
6. Polyurethane-based adhesive tapes are not recommended for use by specialists. It is believed that due to insufficient stickiness, they move away from the base over time.
