XPS Meets New Environmental Regulations for Global Warming Potential

FOAMULAR NGX (Next Generation Extruded) insulation, developed by Owens Corning, is extruded polystyrene (XPS) insulation that contains a proprietary blowing agent, eliminating HFC 134a.

On Jan. 1, Canada and several U.S. states enacted stringent environmental regulations to address concerns about high-Global Warming Potential (GWP) hydrofluorocarbon (HFC) blowing agents. FOAMULAR NGX (Next Generation Extruded) insulation, developed by Owens Corning, is extruded polystyrene (XPS) insulation that contains a proprietary blowing agent, eliminating HFC 134a. FOAMULAR NGX delivers a 90 percent reduction in blowing-agent GWP compared to legacy FOAMULAR insulation and is optimized to demonstrate a greater than 80 percent reduction in embodied carbon. In developing the insulation, research and development teams sought to reduce the blowing agent’s GWP without sacrificing the material’s high R-value per inch, wide range of compressive strengths, moisture resistance and durability.
