For years, customers have relied on Benchmark Foam for high density, high performance expanded polystyrene (EPS) insulation for underneath hydronic-heated slabs. Within the last four years, more than 11 million square feet has been installed.

In most cases, a contractor or property owner specifies the compressive strength, R-Value and insulation thickness of the EPS insulation required for each job. Increasingly, local codes are requiring a minimum R-Value of 10 for insulating under hydronic, or radiant heat systems. Benchmark Foam has different options available for projects that require an R-Value of 10:

2½” Thermo-Snap™ – 16 psi

2½” x 4’ x 8’ – 15 psi

2.3” Thermo-Snap™ – 25 psi

2.3” x 4’ x 8’ – 25 psi

R-10 requires a slightly thicker EPS insulation, so make sure to plan for that thickness to ensure adequate slab thickness. The added thickness of the insulation significantly enhances strength and durability during installation.

Pricing for Benchmark Foam’s R-10 compatible products are competitive to others in the marketplace. However, when you don’t order from Benchmark Foam, you miss out on experiencing the superior quality products from the most responsive EPS foam manufacturer in the industry.
