I am looking at buying a home built in 1900. It looks like it needs a lot of work. One of my concerns is the level of insulation. I had two thoughts about this.
In both cases I would (if I bought the home) eventually gut each room and convert to drywall, so I'd have access to the exterior cavities. I assume a home built in 1900 would be balloon frame.
The two scenarios I can envision are.
1) Hire a company or rent a foam insullation sprayer as I gut each room and do foam insulation in the walls to seal all gaps and then drywall over.
2) This option would be when I gut each room use some type of batt insulation and possibly foam board over top (1/2-1") and then drywall.
Thoughts? Is it possible to rent a foam insulation sprayer?
