Fesco Foam - Flat and Tapered - Insulation and Cover Boards
High thermal, rigid, closed-cell polyisocyanurate foam core produced inline between a Fesco® Laminator Board and a reinforced facer.
Meets the requirements of ASTM C 1289, Type III
Fesco Foam / Tapered Fesco Foam
TopLoc® Coating: Top surface is sealed with this special coating to reduce excessive asphalt absorption in hot-asphalt applied roofing systems.
Rigid Roof Insulation Board: Composed of a closed cell polyisocyanurate foam core bonded in the foaming process to RetroPlus Roof Board on one side and a glass-reinforced facer on the other. RetroPlus Roof Board is an expanded perlite mineral aggregate board.
High Thermal Efficiency: Utilizes an environmentally compliant blowing agent containing pentane hydrocarbon to enhance the thermal performance of the foam insulation.
