Fiberglass Mat for Bituminous Roofing Waterproof Membrane

Fiberglass mats are used as carriers in bituminous roofing applications to provide dimensional stability and tensile strength to a flat roof system. As they do not have a thermal memory, the relaxion time of a fiberglass reinforced roofing sheet is decreased, which makes roof installations more durable and prevents differential movements.

bitumen (roofing) waterproofing membrane

Fiberglass mat  is mainly used as excellent substrates for SBS, APP, PVC waterproofing membrane. It has good longitudinal tensile strength and transversal tear strength. The waterproof membrane which use fiberglass mat has excellent performance of weather resistance and anti-leakage, and can extend the service life. It is an ideal substrate for waterproof materials.
