This is a a rigid, closed-cell, high-density polyurethane foam core panel. The core panel can be manufactured in two types, reinforced and unreinforced. The reinforced panel is a sandwich construction with fiberglass reinforcements. The fiberglass reinforcements are offered in several schedules. The panel's densities range from 20 to 35 lb/ft3 and thicknesses from 1/2" to 2-1/4".

Advantages:
Excellent Strength-to-Weight ratio
Foam Reinforced with fiberglass increases mechanical properties
Lightweight - 30% Lighter Than Marine Plywood
Closed Cell Cross-Linked Polymer Foam will not absorb water
Will Not Rot...Excellent Replacement for Wood

Densities:
Standard Densities range from 20 to 35 lb/ft3

Thicknesses:
Thicknesses range from 1/2" to 2-1/4"
