Tyvek® UV Facade should be placed in the same way as roof tiles, whereby the horizontal overlap must be at least 150 mm. Use Tyvek® Facade tape to tape over staples and overlaps. Tyvek® UV Facade is fixed to constructions using stainless steel staples, and battens are then placed over the staples. VAST-R® Nail-proof tape must be placed under the battens to make sure that the holes produced by screws have a watertight finish. Tyvek® UV Facade must be placed as such that the black side faces outwards. When used together with facade panels, battens must cover the staples on jamb sections. When working around corners, the membrane must be continued to the next jamb section, where it can be fixed in place using staples and possibly a batten. VAST-R® Butyl tape must be placed under the battens to create an effective water barrier, and to extend the lifespan.
