Commercial Insulation

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, expanded polystyrene (EPS) provides the most R-value for each dollar spent.
