CertiFoam 25 SE and SL are rigid extruded polystyrene foam boards suitable for most common residential, commercial, and roofing insulation applications. The closed-cell structure and extruded skins provide superior moisture resistance, high compressive strength, and excellent long term thermal performance. Both meet or exceed ASTM C578 Type IV.

CertiFoam 25 SE is machined square on all edges and pre-scored on 16" and 24" centers for flexible trimming on cavity wall applications.

CertiFoam 25 is also available without scoring.  Contact us for additional information.
