FOAMULAR® NGX™ 400 1 in. x 2 ft. x 8 ft. R-5 Squared Edge XPS Rigid Foam Board Insulation

Product Description

FOAMULAR® NGX™ 400 1 in. x 2 ft. x 8 ft. R-5 Squared Edge XPS Rigid Foam Board Insulation is a high-strength, moisture-resistant rigid foam insulation board designed for demanding structural, commercial, and industrial building applications. Manufactured by Owens Corning, this 1-inch extruded polystyrene insulation board delivers R-5 thermal performance in a convenient 2 ft. x 8 ft. sheet, making it an ideal choice for projects that require superior compressive strength, continuous insulation, improved energy efficiency, and reliable long-term performance in high-load environments. FOAMULAR® 400 XPS insulation is commonly used for plaza decks, parking structures, cold storage, industrial floors, and other applications requiring exceptional load-bearing capabilities. Its closed-cell XPS structure helps resist moisture absorption while maintaining dependable insulating value in demanding environments where condensation, ground moisture, water exposure, or freeze/thaw cycling may be a concern. With its 40 PSI compressive strength, FOAMULAR® 400 is specifically engineered for high-load rigid foam insulation applications where superior strength, insulation value, and long-term durability are critical. The squared-edge board design allows for straightforward installation across large surface areas, helping contractors, builders, and property owners create a continuous insulation layer with fewer thermal breaks, even in challenging structural settings. Whether you are insulating a plaza deck, reinforcing a parking structure, building a cold storage facility, or sourcing high-strength XPS foam board for a commercial construction project, FOAMULAR® NGX™ 400 provides a dependable solution backed by the Owens Corning name.

XPS rigid foam board is valued for its combination of thermal resistance, moisture resistance, dimensional stability, and jobsite durability. Unlike some insulation types that can lose effectiveness when exposed to moisture, FOAMULAR® XPS insulation is designed to retain its long-term R-value even in environments where water exposure, condensation, or freeze/thaw conditions may occur. For builders and contractors, rigid foam insulation can also help reduce thermal bridging when installed as a continuous insulation layer. This can improve overall wall, roof, or foundation performance and support more energy-efficient construction.
