What kind of rigid foam insulation should I install over existing plaster walls before installing new sheetrock?
I have an older house with very little insulation and lots of cracks in the plaster. I would like to insulate by putting a layer of foam board over the plaster, and then covering the foam board with sheetrock. Are there any problems with doing this? I want to use a foam board that is green with no off-gasing.
