4 oz 30" S-Glass Surfboard Fiberglass

The 4 oz 30" S-Glass surfboard fiberglass cloth is designed for surfboard builders who want increased strength and impact resistance compared to standard E-Glass, while maintaining a lightweight feel and responsive flex. S-Glass offers higher tensile strength and improved durability, making it a preferred upgrade for performance boards that need to withstand heavier use or more aggressive surfing.

The 30-inch width provides additional versatility during lamination, especially on shortboards, fish, and mid-length designs. It reduces the need for seams and overlap, allowing for cleaner rail wraps and more efficient material use across a wider range of board shapes.

This premium S-Glass cloth features a tight, consistent weave with a soft drape that conforms easily to curves, rails, and complex contours. It wets out cleanly with both epoxy and polyester resins, producing a strong, clear laminate with excellent structural integrity and long-term durability.

Whether you're building high-performance shortboards or durable everyday boards, this cloth delivers a balance of strength and workability that makes it a reliable upgrade over standard fiberglass.
