Early in the 1950s contractors and carpenters began to realize expanded polystyrene's potential
as an efficient foam insulation for commercial, residential and civil engineering projects. It
didn't take long for the thermal plastic material to become the standard in the industry.
Insulation is often characterized by its R-value. The higher the R-value, the better the resistance
to the flow of heat. Compared to other rigid insulation boards, EPS (expanded polystyrene) provides
the most R-value for each dollar spent.
Benchmark foam Inc has Underwriters Laboratories and Factory Mutual approvals for EPS.

Directory and the Factory Mutual Approval Guide.
