Characteristics: high tensile strength, corrosion resistance, dimensional stability, water resistance, high porosity and easy saturation by bitumen. It is an ideal substrate material for asphalt roofing rolls and shingles. WM/WJ mat can also act as the lining for roof insulation layers to protect polymer foam insulation from the damaging effect caused by chemical solvents in bitumen so as to prolong the lifetime of heat insulation layer.
