Commercial | Residential | Multifamily | Wall

A proven solution for wet environments

Ideal for use in attics, foundations, and crawl spaces, STYROFOAM™ Brand Square Edge Insulation is an extruded polystyrene foam (XPS) insulation that resists water pickup – a characteristic that allows it to keep high R-value.

 
 
 

Styrofoam™ Brand Square Edge

Styrofoam™ Brand Square Edge Insulation* is an extruded polystyrene foam (XPS) insulation board that meets the needs of the commercial foundation and building floor slab market and can also be used for attics, foundations/slabs and crawl spaces in residential applications. With more than 60 years of proven performance in wet environments, the closed-cell structure of Styrofoam™ Brand Square Edge Extruded Polystyrene Foam Insulation resists water pickup, enabling it to retain a high R-value** over time – a necessary property in wet, below-grade commercial foundation applications.
