2” Styrofoam Brand Insulation is probably the most specified rigid insulation material for use under residential concrete slabs with hydronic heat. The material has an R-value of 10 and when used under a heated slab, it forces the heat generated to remain in the slab or to dissipate upward into the living space above instead of being lost into the ground below the slab.
