STYROFOAM Brand SM Extruded

Polystyrene Foam Insulation is a multipurpose extruded polystyrene board that
helps to meet the needs of the commercial
and residential foundation and slab
market. The closed-cell structure of
STYROFOAM Brand SM Insulation resists
water absorption, enabling it to retain a
high R-value (RSI)* over time - a necessary
property in below-grade residential
foundation applications.
STYROFOAM Brand SM Insulation helps
to protect foundation dampproofing
and waterproofing, especially during
backfilling. It also provides a secondary
barrier against groundwater leakage. With
STYROFOAM Brand SM Insulation, the
freeze-thaw cycling of the foundation wall
is minimized, reducing the possibility of
cracking. And a warmer foundation wall
reduces the potential for condensation and
adds to the thermal mass of the building.
Basic Use
STYROFOAM Brand SM Insulation can be
used against almost any commercial or
residential foundation wall in above- and
below-grade applications.
