The manufacture of Firestone Resista AK insulation board is the secret behind its effectivity over the long term when used with EPDM systems. A gastight, multi-layered aluminium complex is laminated to the closed-cell polyiso foam core on both sides to provide the high performance, stable thermal resistance and dimensional stability.
Firestone insulation board is ideal for use on commercial, domestic and industrial installations and is proven over a wide range of geographical climates and locations. Professional installation is recommended to ensure continuing high performance over the expected lifespan.
