Professional-grade 6oz S-glass fiberglass cloth for high-strength surfboard laminations in Sri Lanka. Offers higher tensile strength and impact resistance than E-glass, ideal for mid-lengths, step-ups, longboards, and reinforced decks. Wets out cleanly with epoxy, drapes well over rails, and supports durable layups. Supplied in 100 m × 1 m rolls.
Professional-grade 6oz S-glass fiberglass cloth designed for high-strength surfboard laminations and demanding composite applications in Sri Lanka. S-glass delivers superior tensile strength and improved impact resistance compared to standard E-glass. In a 6oz weight, it provides exceptional durability while maintaining controlled flex characteristics, making it suitable for mid-length boards, step-ups, longboards, and reinforced deck schedules. The cloth features a consistent surfboard lamination weave that wets out cleanly with epoxy resin, allowing efficient saturation without excessive resin absorption. It drapes well over rails and complex curves, supporting both hand layup and factory production workflows. Common applications include: High-performance mid-length surfboards Step-up and travel boards requiring added durability Longboards with reinforced deck schedules Double 6oz deck laminations Rail reinforcement Hybrid layups with carbon or Innegra Supplied in full production rolls of 100 meters x 1 meter width.
What is the advantage of 6oz S-glass over 6oz E-glass?
S-glass provides higher tensile strength and better impact resistance, resulting in stronger laminations at similar weight.
Is 6oz S-glass suitable for heavy riders?
Yes. It is commonly used for boards that need extra structural integrity and dent resistance.
Should I use epoxy resin with S-glass?
Yes. Epoxy resin maximizes the performance benefits of S-glass. Polyester can be used but does not achieve the same strength potential.
When should I choose 6oz S-glass instead of 4oz S-glass?
Choose 6oz when durability, pressure dent resistance, and structural reinforcement are priorities over minimal weight.
Can this be used outside of surfboards?
Yes. Suitable for marine repairs, composite panels, and structural reinforcement applications.
