When the sheets are fastened mechanically, a minimum 10mm free zone between the fasteners edge and the edge of the membrane must be observed. The minimum overlap should be approximately 140mm.

The overlap is calculated in following manner: 10mm free edge + width of washer (normally washers are 40mm wide, tubular washers are 50mm) + 60mm welding zone.
