House built in 1952 w/o insulation on exterior walls. River stone added to west side of house. Need to install insulation on all exterior walls but the west side is the main concern. Other than removing the stone, what would be the easier and more efficient method of installing insulation on that wall? Remove lath rock/plaster on the inside and installing fiberglass or drilling through lath rock/plaster and blowing in cellulose? Also, I prefer doing the work and hoepfully teach my son a few things. Cost is an issue but I don't want to revisit it in 15 years. Kind of a cake and eat it too type of situation.
Any ideas/suggestions?
