Fiberglass

• Precision-woven fabrics produced from continuous glass filaments. Available in 1.0oz, 1.50oz and 2.0oz.
• Characteristics: Plain weave is stable, resists fraying and is easy to handle—ideal for flat or gently curved surfaces. Twill and satin weaves offer better drape and conformability for compound curves and smoother surface finishes. Satin weaves have longer float yarns for improved flexibility; twill shows a diagonal rib that enhances drape and stability.
• Typical uses: Structural laminates, cosmetic outer layers and repairs where finish and conformity matter.

• Overview: Heavy, strong reinforcement made from bundled rovings woven into a fabric with yarns oriented in two principal directions.
• Characteristics: High stiffness and strength for thick laminates; limited drape—better suited to flat or gently contoured panels.
• Typical uses: Boat hulls, large molds and structural applications requiring high load capacity and thickness.

High-strength, lightweight material with excellent stiffness and fatigue resistance but can be brittle under impact or shear. Conductive (needs electrical management), has low thermal expansion and good dimensional stability, and yields excellent surface finish with fine weaves and gelcoats. Best paired with epoxy or vinylester resins (polyester compatible but less ideal) for optimal adhesion and mechanical performance.

Fiberglass tissue is a very light, strong cloth made from extremely thin glass fibers (3–13 µm). It’s made by melting sand, pulling out fine glass threads, and bonding them with a resin. It’s heat-resistant, strong, and used in many industrial and consumer products.
