      I live in a 1920’s house. The walls are uninsulated and I can’t afford to have that done at this time. Does anyone have any experience with radiator covers. I need to get the heat down into the living area and keep it from going out through the wall. I would like to build some. Do they work? How should they be constructed to get the most out of them? Would foil covered foam insulating board work on the wall side or would it melt?Thanks in advance for your help!

      Hi-R polyisocyanurate foil-faced insulation board 1-inch thick would not melt and it would provide an R-value of R6 to help keep the heat from passing through the few square feet of the backing wall. In fact, this foam board comes adhered to sheetrock ttha can be applie over the whole wall. However, it is cheaper to cut the upper molding area away to pour or even hand-apply cellulose insulation to drop down inside the wall and permanently insulate it. It could be done part-time easily.
