DuraFoam - Insulation and Cover Boards
Meets the requirements of ASTM C 1289, Type III
Polymerized Asphalt Emulsion Coating: Allows for the direct application of SBS or APP membranes utilizing heat-weld application techniques.
Rigid Roof Insulation Board: Composed of a closed cell polyisocyanurate foam core bonded in the foaming process to 1/2" thick DuraBoard®, an expanded perlite mineral aggregate board, on one side, and a fiber glass reinforced facer on the other. It's light weight provides ease of handling.
High Thermal Efficiency: Utilizes an environmentally compliant blowing agent containing pentane hydrocarbon to enhance the thermal performance of the foam insulation.
