The Owens Corning® FOAMULAR® NGX™ C-200 Extruded Polystyrene (XPS) Rigid Insulation Board is a premium closed-cell rigid foam insulation engineered to deliver outstanding thermal performance, moisture resistance, and long-term durability for residential, commercial, and institutional construction. Manufactured with Owens Corning's advanced NGX™ technology, FOAMULAR® C-200 provides a stable R-value of 5 per inch while significantly reducing the product's global warming potential compared to previous generations. The butt edge profile allows for tight-fitting installations, making it ideal for continuous insulation systems, foundation walls, basement walls, and under-slab applications.

Each board measures 3" × 24" × 96", delivering an approximate R-15 thermal resistance and covering 16 square feet per board. Each bundle contains 8 boards, providing a total coverage of 128 square feet. With a 20 psi compressive strength, FOAMULAR® NGX™ C-200 withstands moderate structural loads while maintaining excellent moisture resistance and long-term thermal performance. The insulation is GREENGUARD Gold Certified and complies with CAN/ULC-S701.1 Type 3 requirements.

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.
