Dow Styrofoam SM Insulation
Description
STYROFOAM™ SM extruded polystyrene insulation is a multi-purpose extruded polystyrene board that meets the needs of the commercial foundation and slab market. The closed-cell structure of STYROFOAM SM insulation resists water absorption, enabling it to retain a high R-value (RSI) over time – a necessary property in below-grade commercial foundation applications.
