One of the most common and remaining popular in our days is the roofing material. Its popularity is due to its versatility and low price. However, the fragility and insufficiently high parameters cause a lot of criticism for this product.
The company "Technonikol", regularly supplying various novelties to the market, has established the production of the roofing material "Bikroelast", which completely replaces the ruberoid. Call "CCI" its analogue can only be in the first approximation, since the characteristics of this product, the properties and specific application are strikingly different.
Features of "Bikroelast"
* Several varieties are produced under this brand. The article considers a product with the designation "TPP", although the differences from other samples are insignificant - in the structure and individual characteristics.
First, this product simultaneously performs 2 functions - providing steam and waterproofing. Consequently, in the process of finishing the structural elements, there is no need to lay various protective layers.
Secondly, the "core" of the material is glass fiber cloth, coated on both sides with the finest film. It is worth remembering that roofing felt is just a cardboard soaked in bituminous composition.
Characteristics Bikroelast CCI
- Temperature range in which the material does not lose its properties( ºС) - from -15 to +85.
- Moisture Absorption - no.
- Elasticity, which makes it possible to fix the material on uneven surfaces without risk of damage.
- Breakage strength( N) - 800/900( longitudinal / transverse direction).
- Protective coating - film( without logotype from the front side, with logo - with rear, fused).
- Thickness of linen( mm) - 4.
- Standard roll dimensions( m) - 15 x 1.
- Weight( kg): rolls - 45, 1 m2 - 3.
Scope of use
Bikroelast TPP is used for waterproofing roofscalled "pie") or other parts of the structure of structures.
mounting technology It should be noted once again that "Bikroelast CCI" can not be used as a surface protection of the substrate. It must necessarily be "covered" with other material( mastic, lining or other "finish" coating).This is due to the small stability of its protective film before external factors, in the first place - ultraviolet.
Fixation of canvases on the base is made by a fusing method. Therefore, during operation, an open flame source( soldering lamp, gas burner) is required. All preparatory measures are standard( surface cleaning and so on).
Price
Applied to the Moscow region - from 77.8 rubles / m².For roofing felt, this figure is about 19 rubles / m².But considering that the service life of the latter is 4 years, and Bikroelast is at least 10, and you do not need to spend money on the vapor barrier material, it is not so difficult to determine what is preferable.
