Vertical laps should be at least 150mm and horizontal laps at least 100mm. Vertical laps should be staggered and an overlap of at least 300mm should be allowed at external corners. The membrane must be secured with nails or staples at 600mm centres horizontally and 300mm centres vertically. Nails should be of galvanised or sheradized mild steel, austenitic stainless steel, phosphor bronze or silicon bronze, and staples should be of austenitic stainless steel.

It is essential that all timbers particularly the lowest ones in the wall are protected by the Tyvek® Housewrap breather membrane.
