Tyvek® UV Facade should be applied in a shingle fashio where horizontal overlaps should be a minimum of 150mm. Tape off staples and overlap seams with Tyvek® Facade tape. Tyvek® UV Facade 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. Tyvek® UV Facade should be processed with the black side facing outward. When used in conjunction with Facade cladding, a wooden slat is installed over the staples on the batten. At the location of a corner, the membrane should be inverted to the first following batten, where it is fastened with staples and possibly a wooden slat. For optimal water resistance and durability, VASTR® Butyl tape should be applied under the batten.
