Material

DELTA®-VENT SA is a super-tough, lightweight roofing underlay. The 3-layer, high strength spun-bonded PP breather membrane is water vapor permeable, while completely waterproof. A fabric layer on the lower side protects the membrane against damage like roughly sawed sheathing and the matte gray color of DELTA®-VENT SA prevents blinding glare during installation.


Characteristics

DELTA®-VENT SA is highly vapor permeable, allowing moisture within the roof to escape through the membrane. Its high permeability makes it an ideal underlayment for non-ventilated roofs with concrete, clay, or slate tiles. Aside from being completely waterproof, DELTA ®VENT SA by Dorken will protect your roof from even the harshest wind-driven rain and snow flurries.

DELTA ®VENT SA is non-slip, whether your conditions are wet or dry, and always abrasion resistant.

Application

DELTA®-VENT SA is pleasantly lightweight in comparison to bitumen and asphalt saturated roofing felts, which makes the installation process quick and easy. This premium quality product unrolls quickly without skewing or buckling so you can get your roof up and protected in no time at all.
