4 oz 27" S-Glass Surfboard Fiberglass

The 4 oz 27" S-Glass surfboard fiberglass cloth is designed for surfboard builders seeking greater strength without significantly increasing weight. Compared to standard E-Glass, S-Glass offers higher tensile strength and improved impact resistance, making it an excellent choice for high-performance boards that demand added durability while maintaining responsive flex characteristics. The 27-inch width closely matches the width of most standard shortboards, helping reduce excess overlap and material waste during lamination.

Manufactured from premium S-Glass fibers, this cloth features a tight, consistent weave with a soft drape that conforms smoothly around rails, contours, and complex board shapes. It wets out cleanly with both epoxy and polyester resins, producing a clear, durable laminate with exceptional strength and a professional finish. Many builders choose S-Glass when they want increased ding resistance without sacrificing the lightweight feel of a performance board.

Whether you're glassing a high-performance shortboard, step-up, or custom build, this cloth delivers the added strength and reliability trusted by experienced glassers. It is an excellent upgrade for surfers looking to maximize durability while maintaining the responsive performance expected from modern surfboard construction.
