Products / ProtectoR Foam

ProtectoR Foam is a dual-density polyisocyanurate composite board that combines a ProtectoR HD high-density cover layer and a standard-density insulation layer with inorganic coated glass facers in a single board, removing the need to adhere a separate cover board. The data sheet (RS-5638) says the high-density layer meets ASTM C1289 Type II Class 4 Grade 1 and the standard-density layer meets ASTM C1289 Type II Class 2, prints a 48 by 48 inch standard size, and lists production in Bremen, Indiana and Hazleton, Pennsylvania.
