John Nicholas replied to Hal Skinner's discussion How much heat energy is lost through the floor of a house?
"Hal,  Unless you are looking at some type of cantilevered overhang or 'bump out' looking for floors will not get you much. Start looking at foundations and slabs. Hanging any type of insulation from a floor will not help much.…"
