Hope this is the appropriate forum for this discussion...I live in Middle TN in a 70 year old house. It is well built with 1x6 T&G on all interior walls floor to ceiling, hardwood floors, old windows and doors, limestone patchwork for exterior with wood and siding on the gables. About 1300 sq ft. Only about 12" of crawlspace if that. I'm too fat to fit under there.
So my electrical panel was causing problems and I replaced it and upgraded the whole thing to 200 amp. Actually I ripped out all the old wiring as it was the old school cloth and leather clad wires
. In the process, I removed the old trashy drywall and paneling in the whole house and want to replace all of it. I figured if the entire electric system was being replaced, might as well do the wall covering at the same time. Of course by now you may realize I have torn the place up thoroughly and had a good time doing it! It's down to the bare wood walls. I have many challenges ahead but need to prioritize the entire project. Electric part is under control as I have the required experience with that. Insulation and drywall not so much. I'm considering other wall coverings as well.
I discovered the outside walls have no insulation at all and the attic has some sort of blown in insulation. The exterior walls consist of heavy limestone about 2" thick over felt on 1x6 sheathing. On the inside is the tongue and groove 1x6s over the studs.
I guess my question is: Is it advisable to put insulation in the exterior walls at this point? Is it possible I don't need insulation in there? Or do I finish the walls and blow in insulation later? Any insight into this would be appreciated. I would like to redo a ton of things in this house even though I realize there are limitations to what can be done to a 70 year old house. I just want to get the order right and prioritize so I don't cause too many problems down the road. Thanks in advance.
