The Owens Corning® FOAMULAR® NGX™ C-200 Extruded Polystyrene (XPS) Rigid Insulation Board is a premium closed-cell rigid foam insulation designed to provide continuous thermal performance and moisture resistance for residential, commercial, and institutional construction. Manufactured with advanced NGX™ technology, FOAMULAR® C-200 delivers a long-term thermal resistance of R-5 per inch while significantly reducing the product's global warming potential compared to previous generations. The shiplap edge profile creates tighter board joints, helping reduce thermal bridging and improve the continuity of the insulation layer. 

Each board measures 1.5" × 24" × 96", covering 16 square feet per sheet. With an approximate thermal resistance of R-7.5, these boards are ideal for exterior continuous insulation, foundation walls, basement walls, cavity walls, and under-slab applications. Each bundle contains 16 boards, providing a total coverage of 256 square feet. FOAMULAR® NGX™ C-200 features a 20 psi compressive strength, excellent moisture resistance, and is GREENGUARD Gold Certified for healthier indoor environments.

Owens Corning FOAMULAR NGX C-200 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.
