Perimeter, Below-Grade, & Underslab Insulation
With up to 50 percent of a building’s total heat loss occurring at the perimeter and slab of the foundation, below-grade insulation is crucial to achieving energy efficiency. Perimeter, Below-Grade, and Underslab EPS Insulation is a proven and effective method of conserving heat energy in cold climates and air conditioning energy in warm climates.
EPS’s high R-Value, termite resistance, protection against backfill and expansive soils makes it the preferred below-grade insulation among contractors, architects and homeowners.
Types of Perimeter, Below-Grade & Underslab Insulation
Polar-R® Below-Grade Insulation: Film faced EPS for superior
moisture resistance and protection during backfill. Available in 4' x 8' sheets. Used in perimeter, below-grade and underslab applications when a film faced insulation is required.
Polar Fold® Protection Board: Film faced EPS for superior
moisture resistance and protection against backfill. Available in 4’ x 50’ fan fold sheets. Used in perimeter, below-grade and underslab applications when a larger sheets of film faced insulation is required.
