Fiberglass Supply Depot Coosa Nautical 15 Series Composite Board – 1/2” x 2’ x 4’ Sheet | Lightweight Fiberglass Reinforced Panel | Original Marine-Grade Transom & Deck Board

Nautical 15 is Coosa’s highly economical, super lightweight glass-reinforced panel, typically used as a core or low-stress semi-structural component. It has a density of 15 pounds per cubic foot and it is 61% or more lighter than plywood.

• The Nautical reinforced composite panel is engineered by including layers of continuous strand fiberglass reinforcement in a closed-cell high-density polyurethane foam matrix.
• Because the fiberglass exterior does not attract mold, the Nautical composite panel will always be the best no-rot option, even without needing to be treated for this.
• Coosa panels will maintain their initial dimensions even when used in harsh environments and exposed to repeated changes in temperature and humidity.
• Our Nautical composite panels have the lightest weight on the market and are ideal for light structural applications that don’t require the reinforcement that our Bluewater panels offer but still pack lots of strength.
