Fiberglass Roofing Tissue Mat

Fiberglass roofing tissue mat is a wet-laid reinforcement used inside waterproofing membranes and roofing systems. Engineered for compatibility with bitumen and asphalt, the mat is saturated with these binders to form durable, tear-resistant membranes that protect roofs against water ingress and weathering.

Available in weights from 30g to 100g/m², the tissue provides good tensile strength and a uniform fiber distribution, so the saturated membrane resists cracking and stretches consistently across its surface. As a lightweight reinforcement, it adds strength to shingles and membranes without significantly increasing weight or thickness.

Bonded with PVA or polyester binders, the roofing tissue integrates into bitumen-based waterproofing and shingle production lines. It is a core reinforcement for manufacturers of modified-bitumen membranes and asphalt roofing products.

In membrane production the tissue is often called a fiberglass mat or glass mat for bitumen membranes: it is the reinforcement layer that the bitumen or modified bitumen (such as SBS or APP) saturates and coats. Weight, binder, and roll width are confirmed against each membrane line before supply.
