The Owens Corning® FOAMULAR® NGX™ C-300 Extruded Polystyrene (XPS) Rigid Insulation Board is a premium closed-cell insulation board designed for residential, commercial, and institutional construction. Engineered for applications requiring higher compressive strength, FOAMULAR® C-300 delivers excellent thermal performance, outstanding moisture resistance, and long-term durability. With a thermal resistance of R-5 per inch and a 30 psi compressive strength, it is ideal for foundation walls, under concrete slabs, exterior continuous insulation, and below-grade applications.
Each board measures 2" × 24" × 96" and features butt (square) edges for tight-fitting installations. Each board covers 16 square feet, and each bundle contains 12 sheets, providing a total coverage of 192 square feet. Manufactured with Owens Corning's NGX™ technology, the insulation uses a next-generation blowing agent that significantly reduces global warming potential while maintaining the same trusted performance as traditional FOAMULAR® products.
Owens Corning® FOAMULAR® NGX™ C-300 Extruded Polystyrene (XPS) Rigid Foam Insulation is a closed cell, highly moisture-resistant rigid foam board well suited to meet the needs for a wide variety of residential and commercial construction applications.
