Thermo-Cor™ FR

Class 1 Architectural Phenolic Design Foam


With a Class 1 fire rating, Thermo-Cor FR has a higher compression strength ratio than competing phenolic foams of the same density.

Its superior structural strength makes it well suited for stand-alone panels and stress skins used either as thermal or acoustical insulation for commercial applications, especially in hospitals, nursing homes and other public places where low smoke and toxicity are important.
