Lightweight, Non-Absorbent, Mildew Resistant 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.

The lighter of the two Bluewater options, the Bluewater 20 boasts a density of 20 pounds per cubic foot and is over 45% lighter than plywood. The Bluewater20 is often used as a semi-structural component and in other non-structural applications. The benefit of the Bluewater 20 is that it is one of the most economical options without compromising on quality and strength.

Applications for Bluewater 20

  • Hatch lids
