The original marine grade high-density polyethylene building sheet.
Now Available for Upgrade with King FlameShield for our ASTM E-84 Class A or B Flame/Smoke Compliance and CAN/ULC-S102 for Canadian Compliance
King StarBoard® is the original marine-grade high-density polyethylene and the industry standard. It is the product of a proprietary process called K-Stran®, the most advanced manufacturing process available for producing consistently flat continuous sheets. King StarBoard® is environmentally stabilized to withstand the harshest marine conditions. It will not rot or discolor like teak and other solid woods, and it will not delaminate like wood laminates. King StarBoard® is easy to work with using standard woodworking tools, and design changes are a snap. In addition, the installed cost of King StarBoard® is less than teak, other common marine woods, and fiberglass. Plus, our large sheet sizes maximize your yield. Boat buyers appreciate King StarBoard®’s low-maintenance finish. Repair and refinishing due to weathering and decay are eliminated, and cleaning is easy. King StarBoard® has a handsome matte finish on both sides to hide scuffs and scratches that would show on glossy textured sheets or acrylics.
