my basement contractor poured my footings a little high and i dont have room to get my 2 inch insulation over the footings...i can take a little gravel out and get the full 2 inches everywhere but over the footing themselves (i wanted to run the 2 inch insulation over the footings and up the wall the thickness of the floor)
would it be allright to use the 2 inch everywhere possable and then over the footing just use a layeror two of "bubble wrap" type inuslation...or would the heat loss into the footing be too great to use this type of heating..and shouldi just go with forced air

thanks for reading
