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 become reliable protection, which will extend the life of the insulation, preventing its premature destruction. Among other things, with the help of this material it is possible to increase the insulating properties, which will guarantee the extension of the term of use of the main parts of the building. A wind-proof membrane is able to guarantee durability by keeping heat inside the structures.
Key Benefits and Purpose
Izospan is a vapor-permeable membrane, which is actively used in construction to protect the heat-insulating layer, roof, as well as walls and other structural elements that need to be excluded from the influence of moisture and wind. Specialized film provides the removal of water vapor from thermal insulation. When laying the material from the outside, it is necessary to use a technique that provides for the installation of paintings under wall linings and roofing. In the process of manufacturing the material, modern polymers are used, which have many advantages, among them: environmental friendliness, ease of laying, high mechanical strength, long service life, as well as unsurpassed resistance to chemicals. The wind-moisture protective membrane facilitates the installation process for the master, the material is characterized by high mechanical strength, which simplifies installation. It is not capable of releasing substances that would be harmful to the environment or human health. As practice shows, the material retains its performance for a long time, which ensures a long period of use. The membrane is quite resistant to the effects of other building mixtures.
Area of use
Windproof membrane has a wide range of uses. This film can be used for insulation of individual parts of the roof, as well as for the arrangement of walls with an external location of thermal insulation. The material is actively used to protect ventilated facades, as well as a waterproofing layer in the construction of insulated roofs, the slope of which is more than 35 degrees. This windproof membrane can be used for roofs that have different coatings, such as profiled sheets, tiles, metal tiles, as well as bitumen tiles.
For reference
If the membrane will be part of the roof structure, then its installation is carried out under the crate, and a layer of thermal insulation should be located below. 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 area of use
Wind and moisture protective membrane for walls is indispensable for the construction of buildings with external insulation. In this case, the material will protect the structure from the effects of precipitation and the environment. During wall insulation, the membrane is lined under the casing 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-story buildings.
Varieties of the Izospan brand membrane and their differences
The high demand for the described wind protection has led to the need to manufacture these membranes of various types. Each of them has certain characteristics. For example, the Izospan A wind and moisture protection membrane is designed to protect floors, roofs and walls from condensation. The main feature of this film is the ability to evaporate moisture from the inner layer of the roof structure without damaging the thermal insulation. On sale you can find Izospan, which belongs to the AM category. It is a two-layer material that protects the thermal insulation coating from moisture and weathering. Izospan AS is a three-layer material that protects the insulation from external influences of the atmosphere; here, evaporation of moisture can also be attributed. “Isospan”, which is marked with the letter B, creates a protective barrier against internal fumes. But the Izospan S membrane is used for additional protection of non-insulated roofs. It can be used in the arrangement of floor coverings in rooms whose conditions are characterized by high humidity. "Isospan D" is a dense fabric made of polypropylene and coated with a waterproof film. The material is able to withstand high wind loads. Under the DM marking, a membrane is produced, supplemented by an anti-condensation layer, which makes it a universal vapor barrier. If in front of you is Izospan, 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.
Installation
If you are thinking about how to properly install a wind-proof membrane, then the information below should help you. To carry out installation work, you will need the film itself, a stapler, adhesive tape, wooden slats, as well as a set of construction tools. Thermal insulation is mounted on the treated surface, which is placed between the lags or in the crate. A membrane is located on top of the insulation, with its smooth side facing down. Laying is carried out from top to bottom, horizontally. Installation work does not include sagging film, it must be stretched. The membrane is fastened with a stapler, and the distance between the fasteners should be approximately 40 centimeters. The adjacent sheets are stacked with an overlap of 15 centimeters, and the joints should be glued with tape. Wooden slats are strengthened on top of the film to the lags, which allows for a ventilation gap between the next layer and the membrane. Next, you need to carry out finishing work.
Technical characteristics and cost of Izospan A
If you decide to purchase Izospan, the price of this material should interest you. When it comes to labeling under the letter A, then for 1 square meter of such material you 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 1.6x43.75 meters. Some experts are concerned about the question of what is the breaking load across and along. For this material, the characteristics mentioned are 139 and 190 N / 5cm, respectively. Stability to ultraviolet rays lasts for 4 months, but the water resistance is 330 mm. water Art. The temperature regime of operation varies from -60 to +80 degrees. If you will use this material for construction work, then you should also be interested in vapor permeability, which is 3500 grams per cubic meter per day.
On sale in a wide assortment is a membrane of the Izospan brand; the price of this material may vary depending on the purpose. If you have material marked AM, then for 1 square meter you will have to pay 31 rubles. But the AS membrane is even more expensive, its price is 48 rubles. per square meter.
Conclusion
If you choose a wind-moisture protective membrane, the technical characteristics of which were presented above, then you can count on the fact that the material during operation will protect the thermal insulation from moisture and moisture. With its help, you can save heat, as well as save on heating.
