DACHOWA 3 roof membrane

The roofing membranes DACHOWA 3 are used as initial roofing material for inclined roofs.

DACHOWA 3They prevent penetration of rain and snow into thermal insulation and roof structure.

They protect from condensate forming under primary roofing. Additionally, thanks to high-vapour permeability, they keep the entire roof dry, which is of particular importance for energy savings in biuldings.

Also they are for full sheathing!

Advantages of DACHOWA 3 roof membrane:

    • high and uniform vapour permeability,
    • high elasticy and lightweight to facilitate installation,
    • waterproof, sealing the roof,
    • very high mechanical durability,
    • very high resistance to UV radiation,
    • wide product range to facilitate the choice of a proper membrane,
    • complete information available for proper installation.
