Izospan V: scope and installation methods

A person is constantly improving his own home, trying to make it as reliable and safe as possible. First of all, it is necessary to pay attention to the insulation of the foundation, because the more reliable and durable it is, the longer the house can last.

The company "Izospan" has been specializing in the production of materials for vapor barrier for many years. High density and compliance with GOST favorably distinguish the company's products against the background of others. Tens of hundreds of houses are protected with building materials from Izospan, which indicates their unique technical characteristics and efficiency.

This building material makes it possible to protect structures from excessive steam release. It is this circumstance that often leads to serious and destructive impacts, therefore waterproofing is extremely important.

A distinctive feature of the steam is that it can pass through any structure, including concrete. And living in a house without producing steam will not work, because it is a natural product of our life. The only exceptions are vapor-proof materials, but they are extremely expensive and not always suitable for building a house.

In addition, full vapor permeability has a negative effect on the ventilation system of the house. It becomes extremely stuffy in the premises, which will also adversely affect the health of residents. Heaters are also under pressure, therefore, it is recommended to use Izospan B. Without appropriate protection, the heater will soon become unusable and begin to collect moisture, otherwise the properties of the material and its thermal conductivity decrease.

This type of material includes two-layer vapor barrier membranes, which can not only contain moisture, but also prevent steam from passing through them. For the production of such films, only polypropylene is used, which has managed to establish itself as a reliable and effective material. This makes it extremely difficult to tear or damage the film.

Usually Izospan B is produced in rolls, the size and width of which is 160 cm. One roll is enough to cover an area of ​​70 square meters. The main difference is that the material has two sides, so you need to be extremely careful when using it. Each side has a specific function. One of them is smooth, and the second is rough.

In cold weather, the temperature difference in the living room and outside can be significant. As a result, condensation occurs, moisture settles on the heaters.If mineral wool or glass wool was used as the main thermal material, then they get wet and lose their properties and effectiveness.

The unique characteristics of this material make it possible to use it in the following areas:

• when installing roof coverings and counter battens;
• for finishing ceilings, walls or on a subfloor;
• when installing insulation or rafters;
• for interior decoration or exterior cladding;
• as an interfloor insulation;
• for plasterboard finishing. This technology allows you to glue the film even on metal frames.

The official instructions indicate that this building material has a huge number of advantages. And it is true.

Among the main advantages of Izospan B are the following:

• light weight, which greatly simplifies the process of transporting and laying the film;
• high strength, providing resistance to mechanical stress and damage;
• the presence of a double-sided surface, which has a positive effect on the effectiveness of the building film;
• unique technical characteristics that favorably distinguish Izospan B against the background of other products for vapor barrier;
• ease of installation - the product can be installed using the simplest solutions;
• affordable price, thanks to which everyone can afford the purchase of this film for home decoration.

Before using this vapor barrier material, you need to familiarize yourself with a number of requirements that apply to its installation.

Among them are the following:

• If the insulation is finished, mounted on an inclined surface, then all work should be carried out from top to bottom. Izospan B strips must be fixed horizontally, and the overlap must be 15 cm. The use of a special adhesive film makes it possible to isolate the joints.
• It is important to mount the film on the right side of the wall. Not everyone follows this rule, but it is critical and has a direct impact on the efficiency of product use. Incorrect laying completely negates the effect of the use of the material. According to the official instructions, the smooth side is laid on the insulation, and the rough side is directed towards the room.
• The membrane can be attached to the surface to be protected using wooden blocks and clamping strips.

Given the fact that this material for vapor barrier has a wide range of applications, it is necessary to carefully consider the features of its installation on various types of surfaces. Most often, the film is used in the process of insulating the attic. First of all, it is necessary to lay the insulation itself between the rafters, after which it is already possible to stretch Izospan V.

The instruction looks like this:

• Izospan is fixed on the rafters. Experts advise fixing using small bars, the thickness of which does not exceed 5 cm. In some cases, the use of thin strips for pressing is allowed. This method of fastening not only boasts reliability, but also saves the area of ​​the attic. Fastening is possible only if the width of the rafter legs is 3 cm larger than that of the insulation.
• A fine finish is installed on top of the film, which is attached in the same way as the vapor barrier material itself. Due to this, a gap is formed between the finishing finish and the material for insulation, which is needed for the rapid drying of condensate.

The use of this film in the process of roof insulation deserves special attention. If the roof pie is being assembled, then the fastening will be carried out in the same way as in the previous version. However, at the same time, it will initially be necessary to mount the vapor barrier itself. Fixation should be carried out from the outside, and staplers can be used for this. In addition, it is possible to carry out the installation of the lathing from the inside using a narrow board.

After all the preliminary work is completed, you can lay mineral wool or any other insulation on the vapor barrier. In some cases, instead of lathing, you can limit yourself to ordinary wire. It must be pulled very carefully so that the insulation plates are fixed between the rafters without any problems.

Izospan B is a building material that in most cases is used to decorate vertical walls from the inside.

The instructions for use in this case are as follows:

• First, a bar is installed on the surface, the width of which is the same as the thickness of the insulation. If a fine finish is being carried out, then a metal profile can be used, which is extremely important for drywall.
• Now you can start installing mineral wool or expanded polystyrene. Above it is imperative to fix the vapor barrier, after which you can carry out the final finishing.

The process of using film to insulate the outside of the house is slightly different. First, it is necessary to attach a lathing made of a bar to the walls, the thickness of which will not exceed 3 cm. After that, the Izospan V vapor barrier is pulled onto it, and then a counter-lattice is installed. As for the waterproofing film, it can only be attached to the thermal insulation material.

It should be noted that a similar instruction for exterior decoration is suitableprimarily for houses that are built of wood. The fact is that wooden materials are breathable, so they can easily pass moisture vapor. As for concrete walls, they cope better with vapor retention, therefore a vapor barrier membrane is not used so often.

The unique characteristics of Izospan B allow it to be used not only for interior and exterior walls, but also for flooring. Such manipulations must be carried out in cases where it is necessary to guarantee the ventilation gap. The insulating layer itself is mounted between the lags, after which you can start installing the insulation. Experts advise to fix the film with bars, which not only greatly simplifies the installation process, but also ensures its maximum efficiency.

Due to its versatility, this kind of building film can also be used in the process of insulating attic and interfloor floors. The use of the material in this case is practically no different from the use for floor insulation. From the attic side, it will be installed in the same way, but it will also be necessary to attach the film from the bottom side. For fastening, as in other cases, it is best to use small diameter bars.

Above, the main points of using building film for Izospan V vapor barrier were considered. First of all, this material is excellent for finishing the ceiling. The problem is that this part of the room is usually not insulated due to the design and location. Recommendations from experts will help ensure maximum efficiency from the use of this material.

Among the most popular are the following:

• If the walls in the room are made of wood, then they must be treated with antiseptic compounds before vapor barrier. The moisture between the film and the wood dries out extremely quickly, but it's still better to be safe. Otherwise, a fungus may start here, which will not only have a detrimental effect on the condition of the wood, but also may adversely affect the health of the household.

• It is also worth taking care of protecting the wood from insects, since after the end of the work, this will no longer work.
• Izospan B is extremely durable, but the film can be damaged as a result of improper installation or careless handling. You should be extremely careful, since the effectiveness of this material depends, first of all, on its integrity. If there are any torn spots, it is best to repair them with adhesive tape or special glue.

If you believe the reviews, Izospan B is a unique material for vapor barrierwhich boasts high quality, reliability and ease of installation. Due to its low cost, it will be affordable for any person who wants to ensure the durability of his home.
