Abstract
A protective cover assembly is disclosed that comprises a porous expanded membrane having a plurality of pores, a first surface and a second surface opposite the first surface. The porous expanded membrane comprises an active area and a bonded area. The bonded area comprises an adhesive material that forms a bridge extending through the plurality of pores in the bonded area from the first surface to the second surface. The adhesive material in the bonded area improves the Z-strength and allows the porous expended membrane to be a lightweight material having a mass/area ratio of less than or equal to 3 g/m2.
