1-1/2 in. x 4 ft. x 8 ft. FOAMULAR® 150® Extruded Polystyrene XPS Rigid Scored Square-Edge Foam Insulation Board | FMX1.5-15-48SSE-OC

Owens Cornings FOAMULAR Scored Extruded Polystyrene (XPS) Rigid Foam Insulation Board is known for its moisture resistance, thanks to its closed-cell structure, which helps prevent water absorption in environments such as basements, foundations, and exterior walls. This durability extends to freeze-thaw resistance, making it suitable for regions that experience harsh weather changes. While not featuring a reduced GWP agent, it remains a solid choice for energy-efficient, cost-effective insulation solutions in both residential and commercial settings.

• All-purpose foam panel insulation for masonry and other applications
• Ideal for many residential and commercial construction above-grade applications, such as wall furring, cavity wall, sheathing, and other applications
• Applications include cavity walls, wall sheathing, weather-resistant barrier (when joints are sealed), perimeter/foundation walls, basement walls (cannot be left exposed and must be covered by thermal barrier such as gypsum drywall)
