High Density expanded polystyrene (EPS) from Benchmark Foam is a commendable candidate for sub-slab and perimeter insulation applications. Offering the same compressive strength as Owens Corning’s F250 and Dow’s blue board, Benchmark’s High Density provides comparable physical properties – but always at a lower price.

When used under concrete slabs, High Density EPS reduces heat loss and prevents possible heaving. The insulation board also acts as a thermal barrier to make the home or work area more comfortable. To prevent heat loss, many builders opt to use EPS around the perimeter of the building. Using Benchmark’s High Density EPS around the perimeter of a poured concrete slab will prevent frost penetration as well as both normal and tangential frost heaves.

When comparing key properties necessary for sub-slab applications, such as compressive strength and R-Value, high density EPS proves to be a cost-effective, yet durable rigid insulation board. On average, the cost per R-Value of EPS is 10% less expensive than extruded polystyrene (XPS). Start saving money today by switching to Benchmark’s High Density EPS.
