GreenGuard Type IV 25PSI

CertiFoam 25 SE and SL are rigid extruded polystyrene foam boards suitable for most common residential, commercial, and roofing 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 C578-95 Type IV.

CertiFoam 25 SE is machined square on all edges and is pre-scored on 16" and 24" centers for easy nailing.

CertiFoam 25 SL has ship-lap edges on the long side for a tighter fit to reduce air infiltration.  It has stud markings at 16" and 24" centers for easy nailing.
