Izospan AQ proff: properties and purpose

Izospan AQ proff is a popular vapor barrier material and is well known to the Russian consumer. Among the huge number of films and membranes on the modern construction market, professionals often choose this particular model.

Izospan AQ proff is produced at the production facilities of the domestic company “Hex”, which specializes in the production of polymeric building materials. It is included in the group of hydropneumatic membranes and is used to ensure reliable protection of thermal insulation fiber blocks and structural elements of buildings from the effects of steam, wind and moisture. The material plays the role of a compensator for the difference between external and internal temperatures, due to which the formation of condensate is significantly reduced, and, as a consequence, the overall moisture of the walls, insulation plates and floors. The membrane acts as a vapor barrier and prevents the penetration of moisture into the room from the outside, for example, from a wet basement or an unheated attic.

Izospan is a three-layer non-woven material, which is based on membrane polypropylene. The film is characterized by high vapor permeability, thanks to which it easily removes moisture to the outside. This allows you to mount the membrane without using a batten, and lay it directly on the insulation. Material is produced in rolls 1.6 meters wide, the total area of ​​one roll is 70.6 m2. The membrane water resistance is 1000 mm of water column and is governed by the requirements of GOST 3816. The longitudinal tensile strength indicator is quite high and corresponds to 330 H / 50 mm. The value of the resistance to transverse tension is 180 N / 50 mm, which strictly corresponds to GOST 31 899-2.

The working temperature range of AQ proff isospass ranges from -60 to 80 degrees, the density of the material is 180 g / m2, the permeability of permeability per day corresponds to a value of 2100 g / m2, ultraviolet resistance of 12 months. The film is successfully used to perform hydro, steam and wind protection of structures, due to which it is considered to be the universal and most popular means of isolation among membranes.

The popularity and high consumer demand are due to a number of undeniable advantages of this material:

• The complete environmental safety of Isospan AQ proff allows it to be used in any type of civil buildings and industrial buildings without restriction.
• Excellent vapor permeability of the material ensures timely removal of steam, which prevents the appearance of mold and fungus.
• High strength values ​​significantly prolong the service life of the polymer film and eliminate the need for its frequent replacement.

• The water resistance of izospan allows you to reliably protect walls, floors and insulation material from moisture, as well as significantly extend their life.
• Increased resistance to UV rays. The manufacturer guarantees the preservation of the original properties of the membrane, which is under direct sunlight during the year.
• The versatility and versatility of the material allows it to be used to protect structures from steam, rain, snow, condensate and wind.

Of the minuses there is not too high resistance to mechanical loads and the risk of accidental damage to the material from the impact of sharp objects. This is due to the fact that AQ proff izospan is a polymer film and, like any film product, is prone to cuts and punctures.

The range of use of Isospan AQ proff is very wide. The material has proven itself in arranging the insulation of a sloping roof and attic floors, it is recommended for use to insulate frame walls and facades with external insulation.

The ability of the membrane to pass pairs in one direction only protects the insulating blocks from condensation, which can form from the temperature difference between the building structures and the environment. This is especially true for attic floors, which are well heated due to the fact that the warm air in the room rises, heating the ceiling.At the same time, the moisture emanating from the walls does not accumulate in the insulation plates, but is discharged freely through the membrane. Due to these properties, izospan significantly prolongs the service life of fiber plates, which for a long time retain their performance characteristics and do not need to be replaced.

To ensure maximum protection of structures and thermal insulants, isospan should be laid evenly, avoiding the formation of cracks and connecting spaces. Otherwise, because of the violation of the integrity of the coating, the insulation will not be tight enough, and there will be a risk of moisture penetration into the fibers of the insulation board and overlap. Installation of izospana can be carried out independently: the use of expensive tools and the involvement of specialists is not required.

The material is mounted directly on top of the insulation boards and does not imply the formation of an additional batten. The windproof membrane is laid with the white side down and fixed to the fiber blocks with a construction stapler. On top of the film is mounted decorative cladding.

When performing thermal insulation on the pitched roof, the film strips are laid horizontally and fixed with an overlap. Start laying should be below - this will ensure the absence of pockets between the stripes and prevent rain and melt water from flowing under the film. During installation, it is necessary to take into account that a ventilation gap should be left near the ridge of the roof, which will facilitate the normal circulation of air masses and ensure the evaporation of evaporated moisture to the outside. The edge of the membrane is recommended to send in the gutter.

AQ proff three-layer hydro, wind and vapor barrier membrane isopospane is widely used in many types of construction and finishing works and has many positive reviews. High performance characteristics of the membrane are noted, allowing to significantly increase the service life of the fibrous insulation and, as a result, supporting structures and the building as a whole. The material is a domestic product, so it is sold at a comfortable price for consumers. This distinguishes izospan from similar membranes of foreign manufacturers and makes it even more popular and affordable. Attention is drawn to the lack of need to install the batten, which saves a lot of effort and money.
