Bluewater 20 is a medium-density (20 lb/ft³), polyurethane foam board reinforced with layers of continuous strand fiberglass, as well as woven roving for extra stifness.
It is a lighter weight, economical alternative to the Bluewater 26 (26 lb/ft³), yet maintains substantial stiffness and a high strength-to-weight ratio.
Bluewater 20 can be used as a direct replacement for plywood.
It is typically used in semi-structural applications - stringers, decking, hatch lids, cabinetry - that are more critical than where the less stiff Nautical Series will suffice.
Bluewater 20 is available in a wide range of thicknesses - which can eliminate the need to laminate sheets in order to achieve your desired thickness.
3 size options, the popular 4 ft x 8 ft then also 4 ft x 4 ft and 4 ft x 9-1/2 ft for certain thicknesses.
