Tyvek® Solid should preferably be placed directly on roof boarding or other hard surfaces. The membrane should be placed in the same way as roof tiles, whereby the horizontal overlap must be minimum 100mm and maximum 200mm. The membrane is temporarily attached to the underlying construction using stainless steel staples. It should be permanently fixed in place using battens. Tyvek® Solid must be placed so the printed side faces outwards. Tyvek® Solid can be applied to both soft and hard surfaces in facades. When working near corners, continue the membrane to the next jamb section, where it should be fixed in place using staples and/or battens. If the roof pitch is between 15° and 25°, it is recommended to use a more heavy-duty type of roof membrane, like Polytex® Pro (plus), Tyvek® Typrotec (plus) or Tyvek® MaxProtect (plus).
