Renovating solid brick walls in Florida
First off, keep in mind I’m in Florida.
I am fixing my roof eaves and decided to work on the inside of the exterior walls. I have solid brick walls. No air gap, just one layer thick. The old walls simply had heartwood nailed straight on the brick and then Birch paneling…that’s it. Simple enough, right? However, over the corse of 50 years and
neglect, termites ate a lot of that wood. They came uo next to the brick.
Now, the code in my area requires I insulate when redoing the walls. The main two systems are a 2×4 wall next to the brick wall with Batts OR polycianorate foil insulation against the brick with furring over that….both followed by drywall. It’s also advised not to do poly. I don’t like either system
My plan…put a continuous layer of foil insulation against brick using a 1×6 pt board as a bottom seal(termite precautions). Then build a metal stud wall then drywall….does this sound reasonable? I want as much fire and termite resistance as possible.
