Underlayment roofing foil protects the wooden parts of the roof structure and provides thermal insulation against the penetration of water and water vapour produced by human activities inside buildings. And it further prevents the penetration of water, snow, wind, and dirt from the outside into the under-roof spaces.
The foils are supplied in rolls with a width of 1.5 m and a length of 50 m.
If the purchased foil is not installed immediately, we recommend storing the rolls in a vertical position without exposure to sunlight and UV radiation.
