Fiberglass roofing mat is a good base material for making SBS, APP modified asphalt waterproofing membrane and colored asphalt  shingle, and the mat can be reinforced with fiberglass yarn in the longitudinal direction, which improves the longitudinal tensile strength and tear resistance of the felt. Asphalt waterproofing membrane made of glass fiber roofing felt can overcome the shortcomings of high temperature flow, low temperature brittleness, and easy aging. It makes the asphalt waterproofing membrane excellent in weather resistance, enhanced anti-leakage, and prolongs life time, so it is the ideal substrate materials such as roofing linoleum. At the same time, glass fiber roofing felts can also be used as a backing material for the insulation layer of a house.
