XPS Insulation

Trusted Performance

Durable. Versatile. Resistant. Owens Corning® FOAMULAR® is a high-performing insulation, trusted by architects, engineers, builders and contractors to deliver superior insulating power and moisture resistance. Foamular® XPS is well suited to meet the needs for a wide variety of building applications.

The proprietary HYDROVAC manufacturing process ensures a consistent closed-cell structure that is free of voids – keeping moisture out while delivering an R-Value of 5 per inch of thickness. Unlike other rigid foam insulations, testing proves FOAMULAR® insulation maintains its R-Value even when exposed to standing water, wet soil and more.

Available in compressive strengths from 15 to 100 psi and easy to handle on a variety of job sites across all climate zones, FOAMULAR® stands up to your most demanding applications for both above and below grade residential and commercial applications.

Foamular® NGX™ high-performance xps insulation

Owens Corning® FOAMULAR® NGX™ insulation offers all the performance and ease-of-use you expect from Owens Corning® FOAMULAR® insulation with industry-leading sustainability. Learn how FOAMULAR® NGX™ meets the new environmental regulations for Canada and a growing list of US states.


The most important characteristic of insulation is its ability to retain its insulating power (R-value) over long periods of time. Owens Corning® FOAMULAR® XPS insulation is proven to hold its R-Value better than EPS – and even more so when water is present*, such as in below-grade applications. You only have to look at the science to see this truth - science doesn't lie. On top of being more moisture-resistant than EPS*, FOAMULAR® XPS is easier to cut and has superior durability. When it comes to XPS and EPS, there is truly no comparison.

*ASTM C272 and ASTM C518. Also see Owens Corning technical document: "Extrusion Matters" for more details.
