1 in. x 4 ft. x 8 ft. R-5 Tongue & Groove Edge Insulation Sheathing
All-purpose foam panel insulation for masonry and other applications. Owens Corning FOAMULAR® 150 extruded polystyrene insulation is ideal for wall furring, perimeter/foundation, cavity wall, crawlspace, pre-cast concrete, under slab, sheathing and other applications (Not approved for roofing). Owens Corning’s patented Hydrovac® process technology makes the unique closed-cell structure of FOAMULAR® extruded polystyrene insulation highly resistant to moisture, retaining its long term R-value year after year – even following prolonged exposure to water leakage, humidity, condensation, groundwater and freeze/thaw cycling. High-performance FOAMULAR® 150 extruded polystyrene insulation works to:
- Retard the transmission of water vapor and moisture in masonry walls, helping prevent structural damage.
- Provide insulation in a metal or wood furring system used for masonry or concrete walls.
- Perform below grade in perimeter and foundation applications to complement the insulating sheathing envelope around the building framing.
Resistant to common soils and decay, Owens Corning FOAMULAR® extruded polystyrene insulation retains its insulating performance characteristics even after prolonged exposure to moisture. Owens Corning’s FOAMULAR® extruded polystyrene insulation is an ENERGY STAR® qualified product. Green Approved by the National Association of Home Builders.
