            More About Owens Corning Foundations Slab Insulation

            Our XPS insulation products significantly reduce heat transfer through the ground, maintaining consistent indoor temperatures and potentially lowering heating and cooling costs. The built-in moisture resistance of XPS helps prevent water penetration. The comfort of well-insulated floors, particularly in areas in direct contact with the foundation slab, showcases the thoughtful engineering of our foundation insulation products.

            Our XPS products, made with extruded polystyrene insulation, boast thermal resistance with R-values from 5 to 15, suitable for a variety of applications, including under slab insulation, slab edge, and concrete floors, as well as for foundations, roadways, rail beds, and cold storage installations. Their robust load-bearing capabilities make them a versatile and durable choice for addressing diverse construction challenges.

            In addition to our versatile XPS insulation products, Owens Corning offers cellular glass insulation solutions ideal for foundation slabs requiring compressive strength and long-term durability. This insulation is designed to withstand heavy and continuous loads, making it an excellent choice for areas that experience intense use or where maintaining structural integrity is non-negotiable. Its water resistant contributing to sound and energy-efficient construction.

            By opting for Owens Corning, you're not just choosing insulation products; you're choosing a partner dedicated to providing solutions that enhance building performance and ensure durability.
