No-Rot composite panels for the marine industry


Nautical Panels have outstanding physical properties from the inclusion of layers of continuous strand fiberglass reinforcement in the closed-cell polyurethane foam matrix.  Removing the woven roving layers found in our Bluewater series results in a lighter weight series, at a lower cost, and designed for light-structural applications requiring a little less stiffness than the Bluewater series. These lighter composite panels do not attract mold or fungus and still absorb less than 1.5% water by weight

Coosa’s Nautical Panels are manufactured by our skilled employees in a safe and environmentally friendly facility. We use the finest polyurethane and fiberglass available, ensuring our quality products will remain non-absorbent, stable, and tough under normal and non-abusive use.
