Tyvek Metal Air-permeable Diffusion Membrane with Air Layer 1.5x25m, 37.5m2

Diffusion membrane with polypropylene mesh for copper, titanium, metal roofs with complex construction. Provides constant roof ventilation, condensate drainage, and sound insulation during rain and hail up to 8 dB. Installed on a continuous substrate. Country of origin: Luxembourg. Diffusion membranes combine the properties of multiple films. They protect thermal insulation and wooden structures as waterproofing and at the same time protect thermal insulation from heat loss due to wind action (blowout). Like windproof insulation, they must have high water vapor permeability, which ensures easy moisture escape from roof structures. 25-year lifespan guarantee.

Lay tightly against thermal insulation. If laying horizontally, create 10-15 cm overlaps. Overlap areas should be sealed with frost and moisture-resistant adhesive tapes (such as Tyvek Tape or Gerband Outside DM Tape (386)). Create ventilation gaps above the membrane.
