Strong, Structurally Sound, Cost Effective Core Material

The Bluewater composite panels are made from high-density closed-cell polyurethane foam reinforced with continuous strand fiberglass and woven roving. They're quickly becoming an industry standard for lightweight building applications that previously called for the use of plywood.

The Bluewater series is ideal for projects in marine or high-humidity settings. While the Bluewater series is fantastic in aquatic environments, it's also just as suitable for applications that require a high strength per cubic foot ratio with the added benefit of being lighter than plywood.

With impressively high strength-to-weight ratio, this is easily considered Coosa's most robust panel. The woven roving and continuous strands of fiberglass make the Bluewater 26 the stiffest panel that we offer. The structural integrity of these panels is unmatched which enables them to be used in multiple applications. The Bluewater 26 panels can be used interchangeably in non-structural applications as well as more demanding applications where it acts as a structural component.The Bluewater 26 is strong and over 30% lighter than plywood alternatives. The very low water absorption makes these panels a perfect choice for applications that need a no-rot, low weight, and high strength product.
