Closed-cell 4x8 pvc foam sheet is a light-weight rigid material used primarily in the manufacture of signs and displays. It is considered robust for outdoor use, being immune to rain and resistant to wind and sunlight.PVC foam boards are distinct from the extra-lightweight foam-core board, laminated of foam and card surfaces, used for indoor signage and modeling. Closed-cell PVC foam board's material properties have also made it extremely popular among makers of models and props, and builders of yachts and composite experimental aircraft.
