Any cooler surface in contact with the slab will try to steal its heat. A continuous layer of horizontal insulation reduces heat loss in the winter and it reduces condensation of humid air on the slab during the summer. Determining how much insulation. Downward heat loss from a radiant slab should not exceed 10 percent of upward heat output a ratio derived from european installation standards for floor heating systems it s possible to calculate the r value needed to meet.
