I have a room that is over a crawl space. The room has hardwoord floors. Last year I had the permiter of the crawl, and the block walls stripped of the old wet pink insulation, and sprayed with the yellow foam. This definately helped with the temperature of the room, and the coldness of the floor. Would it be beneficial to also insulate (maybe with the pink stuff) the floor joists under the floor? I live in the midwest--10 to 30 degrees most of the winter.
thanks.
