Karen writes from Marine City, Michigan: "Will it make my ceramic floor warm if I spray insulation on the floor boards under my house?"

Answer: Owens Corning does not manufacture spray insulation so I don't have any information on that product. The company does manufacture FIBERGLAS™ insulation that can be installed under the floor. Insulation works by slowing the transfer of heat, so while insulation will not "make the floor warm" it will help to maintain heat in the room and the tile should feel warmer in cold weather.
