What is the best way to insulate a heated slab?
rFOIL Ultra CBF (Concrete Barrier Foil) provides the ideal insulator for a heated slab. The inner layer of foil reflects the radiant energy that you put into the floor. This way, more of the energy you pay for actually heats the living space, rather than sent to the cold ground below. Board insulations do not stop radiant heat flow. Ultra CBF is more cost-effective that 2 foam board, easier to install, will not crack at the seams, can serve as the expansion joint at the edge slab, and has 5 TIMES the compression strength of the best board insulation available.
