Fibreglass Chopped Strand Matting 450g 1m wide

Heavy-duty chopped strand fibreglass mat (450g/m²), 1m wide—perfect for building strong laminates, moulds, repairs, and GRP composite applications.

Our 450g/m² Chopped Strand Matting, available in a practical 1‑metre width, is a staple in building robust fiberglass laminates and composite repairs. Made from randomly oriented E‑glass strands bound with a styrene-soluble emulsion, it wets out quickly and is compatible with polyester and vinylester resins, making it ideal for GRP (fiberglass) moulding, repairs, and structural reinforcement.

This heavier mat adds both strength and thickness in a single layer, making it efficient for applications like boat hull repairs, roofing repairs, pond and tank lining, and mould-making. Its random fibre orientation ensures balanced strength in all directions, and it readily conforms to both flat and curved surfaces. 

In boat building and GRP repair, 450g matting is highly valued when a durable and thick laminate is needed. In more demanding, foot-traffic areas, it is often paired with woven fabric for added load-bearing performance. 

Sold by the linear metre, this mat provides flexibility for both small-scale maintenance and larger project applications, offering marine-grade reinforcement that's both efficient and cost-effective.
