Polytex® Pro is a water-resistant and extremely breathable, 2-layer spunbond membrane composed of HDPE and polypropylene, based on Tyvek® DuPont technology. The membrane is flexible, has very high nail tear resistance and is easy to process. Due to the functional Tyvek® layer, Polytex® Pro has high temperature resistance. The Polytex® Pro Plus features an integrated adhesive strip that eliminates the need for a Tyvek® tape at the overlaps.

Polytex® Pro is used as a waterproof and extremely breathable layer on the cold side of facade and roof structures. This membrane is completely waterproof and can therefore also be applied directly to hard substrates (such as the roof boarding). Polytex® Pro is used in both new construction and renovation work.
Polytex® Pro should be applied in a shingle fashion with horizontal overlaps being at least 150 mm. Staple and overlap seams with Tyvek® tape. Polytex® Pro is applied to the structure using stainless steel staples after which the battens are placed over the staples. VASTR® Nail Sealing Tape should be applied under the batten to ensure water tightness of screw hole connection. Always apply Polytex® Pro legibly from the outside. When used in conjunction with Façade cladding, a wooden slat is installed over the staples on the batten. At the location of a corner, the membrane should be converted to the first following batten, where it will be fastened with staples and possibly a wooden slat. For optimal water resistance and durability, VASTR® Butyl tape should be applied under the batten.
