Fiberglass 1 Ply/Foam

ACP’s Fiberglass 1 Ply / Foam Panels are manufactured by sandwiching a foam core between a single ply of Fiberglass pre-preg. The fiberglass foam sandwich panel consists of a 6 lb. /cu. ft. foam core in 1/8” or 1/4 thicknesses with 8oz., 8Hareness Satin weave Fiberglass pre-preg on each side. These panels demonstrate light weight and high compressive properties and are lighter than balsa core panels. More details...
