2 in. x 4 ft. x 8 ft. R-10 Scored Squared Edge Insulation Sheathing
Owens Corning FOAMULAR® 250 extruded polystyrene insulation is ideal for wall furring, perimeter/ foundation, cavity wall, crawlspace, pre-cast concrete, under slab, roofing systems, sheathing and other applications (Not approved for roofing). Owens Corning’s patented Hydrovac® process technology make 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, condensation, ground-water and freeze/thaw cycling.
Excellent insulation performance for a wide variety of building requirements, high-performance FOAMULAR® 250 extruded polystyrene insulation works to:
- When joints are taped, helps provide a weather resistant barrier to enhance the longevity of the building.
- Provides insulation in a metal or wood furring system used for masonry or concrete walls.
- Performs below grade in perimeter and foundation applications, or directly beneath the concrete slab to complement the insulating sheathing envelope around the building framing.
FOAMULAR® extruded polystyrene insulation is ideal for below grade applications. Extruded polystyrene (XPS) is resistant to degradation from material common to most soils and will retain its insulating performance characteristics even after prolonged exposure to moisture.
Owens Corning’s FOAMULAR® extruded polystyrene insulation is an ENERGY STAR® qualified product.
