Abstract

The laminate comprises a melt-blown layer 22 and at least one spun-bond layer 24, 26, preferably as an SMS laminate. The melt blown layer 22 has a basis weight ² 35 (25-34) g/m2 and comprises fibres having a diameter ² 2.5 (2.2-2.4) µm. Preferably the laminate has a hydrostatic head > 100 cm and air permeability > 20 l/m2/s. Preferably, the melt blown and spun bond layers comprise polyolefin, especially polypropylene fibres. The preferred spun bond layers 24, 26 have basis weight = 15-150 g/m2. The preferred laminate, containing fluorocarbon hydrophobic melt additive, UV absorber, flame retardant, pigment or plasticiser, is point bonded with heated calender rollers. The laminate is used with an unsupported or fully supported roof.
