The smart combination for maximum security.
Material
DELTA®-VENT S is a supertough, 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 (eg. roughly sawed sheathing.) The matte grey color of DELTA®-VENT S prevents blinding glare during installation.
Product Characteristics
DELTA®-VENT S 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. The product is completely water proof, and will protect the roof from wind-driven rain and snow.
The materials used provide a special surface structure which makes the product non-slip (wet or dry), and abrasion resistant.
Application
DELTA®-VENT S is pleasantly light in comparison to bitumen and asphalt saturated roofing felts, making the installation quick and easy. This premium quality product unrolls quickly without skewing or buckling.
