Customers often call us inquiring about floor insulation. We strongly encourage homeowners to check their attic insulation and make certain it is up to R-30 prior to insulating their floors. More often then not, cold is not coming in from the floor, but rather the heat is escaping through a poorly insulated attic. Once the attic is well insulated, the heat is retained in the home and the overall feeling is that of a warmer home. Remember, it is not that cold comes in, but rather that heat is lost. The floor may feel cold, but it is reflective of a cold interior temperature.
Have you ever walked into a 70-degree room? It feels quite comfortable, neither warm nor cold. Try walking into a 70-degree swimming pool; it feels freezing! The reason for this is because the cool water is much cooler then your skin and you sense the heat leaving your body. Same holds true for cold floors. The floors are actually about the same temperature as the room, but because your foot is touching the floor, it feels dramatically cooler.
Too often people have the floors insulated and they continue to complain that the floors are still cold. It’s essentially to have a properly insulated attic and even walls before doing floors, and that is why the Government offers rebates for attic and wall insulation, but not for floors.
