High temperature resistant fire retardant aluminum foil phenolic foam board roof insulation

Phenolic foam board

Phenolic Foam is a closed cell rigid plastic foam comprising of phenolic resign and other additives.It has been recognized as the best insulation materials beiling for the excellent fire performance, low smoke emission, high temperature resistance, superior thermal performance, stability, extremely sound insulting property and structural strength performance.

Its thermal conductivity

The thermal conductivity of Phenolic Foam is very low(0.021~0.032W/mk), compared with traditional insulation materials such as mineral wool,rock wool,glass wool (0.043~0.052) and expanded perlite(0.065~0.083), its energy-saving and insulation performance is double, in common with polyurethane. It is being generally acknowledged as the world's top insulation materials.
