Product Datasheet Icon


Uni-Web S-Glass is a new and easy to apply fiberglass reinforcement. It consists of a non-woven sheet of unidirectional S-glass fiberglass fibers that are held in position by a fine spider web of polymer fibrils that rest on the surface. The fibril or web system allows the fabric to be cut easily, trimmed or slit, giving clean edges with absolutely no fraying. The fibers lie flat and straight, and cannot shift or bunch up, as often happens with uni-stitched fabrics.

S-glass fiber is superior in strength to standard E-glass, making the Uni-Web S-Glass perfect for high strength, weight critical applications where exact placement of the fiber is needed.
