Fiberglass Roofing mat is mainly used as excellent substrates for waterproof roofing materials.It is characterized as high tensile strenth,corrosion resistance,easy soakage by bitumen, and so on. The longitudinal strength and tear resistance can be improved further by incorporating reinforcements into the tissue across its whole width. The waterproof roofing tissue made of this substrates is not easy to crack, ageing and rot. Other advantages of waterproof roofing tissue are high strength, excellent uniformity, good weathering quality and leaking resistance.we can produce the goods from 40gram/m2 to 100 gram /m2,and the space between yarns is
