Bluewater Panels

Our Strongest Fiberglass Reinforced Composite Panel

Coosa’s premier panel product for structural and non-structural applications is the Bluewater series panel. It is a composite panel created with high-density, closed-cell, polyurethane foam reinforced throughout with layers of woven roving and continuous strand fiberglass. These panels will not attract mold or fungus, and absorb virtually no water. At 55 – 70% the weight of plywood, they are primarily used as plywood replacement material.
