SEMI-RIGID ASPHALT BOARD

Semi-rigid board is composed of a mineral fortified asphaltic core formed between two saturated fiberglass felts. This board is designed to be used as a substrate material in low-slope roofing. It can be installed over wood, rigid insulation or as a recovery board over an existing roof surface to be re-roofed.
