Windproof protection membrane "Izospan": technical characteristics, installation

During the construction and insulation of buildings it is important to ensure high-quality wind, steam and waterproofing. From the negative impact of environmental factors, a membrane will be a reliable protection, which will prolong the life of the insulation, preventing its premature destruction. Among other things, this material can increase the thermal insulation properties, which will guarantee the extension of the period of use of the main parts of the building. Vetrovagazashchitnaya membrane is able to guarantee longevity, keeping heat inside the buildings.

Main advantages and purposes

Isospan is a vapor-permeable membrane that is actively used in construction to protect the thermal insulation layer, the roof, as well as walls and other structural elements that need to be excluded from the effects of moisture and wind. Specialized film provides removal of water vapor from thermal insulation. When laying the material from the outside, it is necessary to use a technique that involves the installation of canvases under the wall lining and roofing. In the process of manufacturing the material, modern polymers are used which have many advantages, including: ecological compatibility, ease of laying, high mechanical strength, long service life, and unsurpassed resistance to chemicals. The wind-proof membrane facilitates the master installation process, the material is characterized by high mechanical strength, which simplifies the laying. It is not capable of releasing substances that are harmful to the environment or human health. As practice shows, the material maintains its performance for a long time, which ensures a long period of use. The membrane is sufficiently resistant to the effects of other building mixtures.

Scope of use

Vetrovagazashchitnaya membrane has a wide scope of use. This film can be used for the insulation of individual parts of the roof, as well as for the arrangement of walls with an external arrangement of thermal insulation. The material is actively used to protect ventilated facades, as well as a layer of waterproofing in the construction of insulated roofs, the slope of which is more than 35 degrees. This wind and moisture protection membrane can be used for roofs that have different coatings, such as profiled sheets, tiles, metal tiles, and bituminous tiles.

For reference

If the membrane is part of the roofing structure, then its laying is carried out under the crate, and a layer of thermal insulation must be located from the bottom. Thus, from below there will be rafters. The material is able to protect the structure from the wind, while the supporting elements will be reliably protected from condensation.

Additional information about the scope of use

Vetrovagozashchitnaya membrane for walls is indispensable in the construction of buildings with external insulation. In this case, the material will protect the structure from the effects of atmospheric precipitation and the external environment. When the walls are insulated, the membrane is lined under the lining on the outside of the insulation layer. Today, the described material is often used in the role of a protective layer of thermal insulation during the arrangement of a ventilated facade. In this case, we can talk about multi-storey buildings.

Varieties of the Izospan membrane and their differences

The high demand for the described wind protection has led to the need to manufacture these membranes of different types. Each of them has certain characteristics. For example, the wind and moisture protection membrane "Izospan A" is designed to protect floors, roofs and walls from condensation. As the main feature of this film is the ability to evaporation of moisture from the inner layer of the roofing structure without harming the thermal insulation. On sale it is possible to meet "Izospan", which belongs to the AM category. It is a two-layer material that protects the thermal insulation coating from moisture and weathering. "Isospan AS" is a three-layer material protecting the thermal insulation from external influences of the atmosphere, here it is also possible to attribute evaporation of moisture. Izospan, which is marked with the letter B, creates a protective barrier against internal evaporation. But the membrane "Izospan C" is used for additional protection of unheated roofs. It can be used in the arrangement of floor coverings in rooms, the conditions of which are high humidity. "Isospan D" is a dense fabric made of polypropylene and covered with a waterproof film. The material is capable of withstanding a high wind load. Under the marking DM, a membrane is added, supplemented with an anticondensate layer, which makes it a universal vapor barrier. If before you isospan, which is labeled FB, then you can use this material in the construction of saunas and baths. The layer will be able to reflect infrared radiation.

Mounting

If you are thinking about the question of how to properly install the wind deflector membrane, then the information below should help you. For installation work, you will need the film itself, a stapler, an adhesive tape, wooden slats, and a set of construction tools. On the surface to be treated, thermal insulation is installed, which is laid between the lags or in the crate. On top of the heater there is a membrane, with its smooth side facing downward. Laying is carried out from the top down, horizontally. Installation work does not involve sagging the film, it must be stretched. Fastening of the membrane is carried out with a stapler, and the distance between the fasteners should be about 40 centimeters. Neighboring sheets are stacked with an overlap of 15 centimeters, and joints should be glued with tape. Over the film to the lags are reinforced wooden slats, which allows to provide an air gap between the next layer and the membrane. Further it is necessary to carry out finishing works.

Technical characteristics and cost of Isospan A

If you decide to purchase Isospan, the price of this material should interest you. When it comes to marking under the letter A, then for 1 square meter of such material will have to pay 22 rubles, while the roll contains 70 square meters. It is made of 100% polypropylene, and the dimensions of one roll are equal to 1.6x43.75 meters. Some experts are concerned with the question of what is the breaking load across and along. For this material, the mentioned characteristics are 139 and 190 N / 5 cm, respectively. Stability to ultraviolet rays persists for 4 months, but the water resistance is 330 mm. Water. Art. Temperature operating mode varies from -60 to +80 degrees. If you use this material in construction work, then you should be interested in the vapor permeability, which is 3500 grams per cubic meter during the day.

On sale in a wide range of products is a membrane of the Isospan brand, the price of this material can vary depending on the purpose. If you have a material labeled AM, then for 1 square meter you have to pay 31 rubles. But the membrane AS is even more expensive, its price is 48 rubles. Per square meter.

Conclusion

If you choose a windbreak protection membrane, the technical characteristics of which were presented above, then you can count on the fact that the material in the process of operation will protect the thermal insulation from the effects of dampness and moisture. With its help you can store heat, and also save on heating.
