Diffusion membrane combines the features of several films and as such it is a combination of film. These membranes at the same time protects the insulation and wooden structures of the effect of water as a waterproofing material and waste of energy of wind and wind-proof insulation. Membrane structure allows water vapor to move freely on the outside, but does not allow moisture to enter the insulation from the outside, thereby ensuring its effective work.
The diffusion membrane may be two, three or more layers. Two-layer membranes are less resistant to mechanical damage, so it INSTALLING need more attention. r134a temperature pressure chart Three layers of film are more tolerant as bring the diffusion layer covered with a special protective coating. Four-layer diffusion film is an exceptionally strong, as they are incorporated into the manufacturing process, special reinforcement. Thus, the membrane acquires additional strength and are flexible. Provides a high vapor diffusion through the membrane surface evenly distributed r134a temperature pressure chart micropores with a diameter of 1-2 microns. The average quality of the product diffusion membrane service life is 50 years. r134a temperature pressure chart
Diffusion membranes are widely used especially pitched roof structures, especially mansard. Membrane Application Form to the cold attic conversion of attic space, without changing the existing rafter construction. All diffusion membranes can be used as a wind barrier layer. Diffusion membrane is covered tightly with insulating material layer of paper and applying make up from 10 to 15 cm overlaps. Note that the diffusion membrane is covered with colored side up. Conversely, if the roof pitch is less than 25% overlap between sites are glued to frost and moisture-resistant adhesive tape to ensure optimal use of the membrane. r134a temperature pressure chart
