Foundation & Below-Grade Insulation Products

XPS insulation, a robust closed-cell foam, excels in environments prone to moisture due to its inherent water resistance and minimal degradation over time. Its superior R-value boosts the thermal efficiency of foundations. 

Cellular glass insulation is recognized for its outstanding compressive strength and vapor barrier properties. It is particularly effective in applications demanding non-combustible materials and substantial load-bearing strength, such as foundation walls and under-slab installations. Our XPS and cellular glass insulation products are also ideal for exterior foundation insulation, providing effective thermal barriers that enhance the building's envelope. 

In a variety of commercial settings—from hospitals and educational facilities to industrial complexes—Owens Corning’s foundation insulation systems provide optimal environmental control and enhance energy efficiency. Our XPS and cellular glass products deliver reliable, long-lasting performance, especially suitable for variable climates ranging from cold northern regions to humid coastal areas. Whether stabilizing indoor conditions in a data center or reducing operational costs in a retail center, our insulation solutions are tailored to meet diverse building needs. 

These insulation materials protect against moisture, stabilize indoor temperatures, and maintain structural integrity.
