The 4 oz Standard (1522) and 4 oz Warp Enhanced (1521) Fiberglass Cloth are high-quality E-glass woven fabrics designed specifically for surfboard manufacturing, composite reinforcement, and lightweight laminates.
The standard 4 oz cloth provides excellent clarity, smooth drapability, and easy wet-out for general surfboard lamination, while the Warp Enhanced 1521 version offers increased warp-direction strength, improved tensile properties, and greater durability—ideal for high-performance boards.
Both fabrics deliver a clean finish, stable construction, and reliable performance for both polyester and epoxy surfboard laminations.
Smooth and consistent plain weave
Excellent transparency and laminate clarity
Easy to drape on curved surfboard profiles
Ideal for lightweight performance surfboards
Increased warp strength due to higher warp yarn count
Improved tensile performance and durability
Reduced stretch and better board stiffness
Suitable for high-performance and heavy-use surfboards

Q1: What is the main difference between 1522 and 1521 surfboard cloth?
A1: 1521 has reinforced warp yarns for higher tensile strength and improved durability compared to 1522.
Q2: Which resin system is recommended for surfboard lamination?
A2: Both polyester and epoxy work well; epoxy provides higher clarity and strength.
Q3: Is 4 oz cloth suitable for both top and bottom laminations?
A3: Yes. 4 oz is commonly used for bottom layers or double-layer deck reinforcements.
Q4: Can these cloths be used for board repair?
A4: Yes, both versions are ideal for ding repairs and small-area reinforcement.
Q5: Do the rolls support custom widths or lengths?
A5: Yes, custom sizes can be produced based on customer requirements.
