FOAMULAR® NGX™
Extruded Polystyrene
(XPS) Rigid Foam Insulation
A closed cell, highly moisture-resistant foam board, it meets the needs for a wide variety of residential and commercial building applications. The formulation and production meets or exceeds the new, more stringent regulatory standards without sacrificing performance. You can feel confident specifying FOAMULAR® NGX™ in the same places you’d specify legacy XPS – like wall assemblies, below-grade foundation walls & slabs, and vegetative roof assemblies.

How we are making it greener and healthier
More than six years of R&D and the evaluation of over 100 blowing agent formulations by Owens Corning’s polymer scientists took the industry-leading sustainability of FOAMULAR® NGX™ from the lab to the worksite.
Manufacturing and material composition matter when it comes to sustainability. That’s why we continue to invest in efficient manufacturing. FOAMUAR® NGX™ is GREENGUARD Gold certified, reusable, made with 100% wind electricity, and contains a minimum of 20% recycled polystyrene, as certified by Scientific Certification Systems.
With zero ozone depletion potential, specifying and installing FOAMULAR® NGX™ helps builders achieve LEED, ENERGY STAR®, and Green Building Standard ICC 700-2008 certifications.
