The house in question is circa 1920, stucco exterior with lathe and plaster in interior (no insulation). I will be insulating the subfloor and attic (any suggestions for a good material to use?).
The main question I have is should I bother with cavity fill insulation for the walls. What are your thoughts: too risky, too difficult, not effective? If you think it is a worthy task, what would be a good cavity fill material? Install from exterior or interior? What about wiring in the walls, will those be problematic?
Thanks in advance.
