FIBERGLASS FRP PRODUCTS

HL-FS mat is mainly used as substrates for water-proof roofing materials. It is characterized by high tensile strength, corrosion resistance, dimensional stability, water resistance, high porosity and easy saturation by bitumen. The longitudinal strength and tear resistance can be improved further by incorporating reinforcements into the mat across its whole width. The asphalt roll roofing substrates with HL-FS mat can overcome problems existing with paper felt such as low-temperature cracking, high-temperature melting, liable to aging, rotting and leaking, Other advantages with HL-FS mat is an ideal substrate material for asphalt roofing rolls and singles. HL-FS mat can also act as the lining for the roof insulation layers to protect polymer foam insulation form the damaging effect caused by chemical solvents so as to prolong the lifetime of heat insulation layer.
