Description

Styrofoam Brand SM Extruded Polystyrene Foam Insulation is a versatile, multipurpose extruded polystyrene board that fits
the needs of the commercial and residential foundation and slab market.

Styrofoam Brand SM Insulation’s closed-cell structure resists water absorption, enabling it to retain a high R-value (RSI)**
over time, a necessary property in below-grade residential foundation applications. It helps to protect foundation dampproofing and waterproofing, especially during backfilling.  It also provides a secondary barrier against groundwater leakage.
