Past experiences in upgrading wall insulation of a (solid) brick building?
I’ve learned that even with all the energy-efficient, air sealing, etc..stuff that I do in my house, that until my wall insulation is upgraded, I will be uncomfortable because of convective loops.
The walls from exterior to interior consists of:
a) two-wythe brick
b) 3/4″ – 1″ kraft faced fiberglass bat (not tightly installed)
d) drywall attached to brick with furring strips (no wall)
…which of course is the worst for a brick building.
If I did want to upgrade the insulation, I believe that means I have to tear down all drywall, tile, and spray closed cell foam on the walls to a thickness that meets Zone 5 requirements, and then reinstall interior finish. Probably some electrical & plumbing work.
1) Can anyone share ANY previous experience with doing this in a residential setting. Just looking for real-world experience & not some text from a report or study.
2) What is a typical cost associated with this?
3) If after getting the batts of the walls & mold is found in a great capacity, what would a typical remediation job consist of? Yes humidity is typically high even with a properly-vented bathroom fan & a couple who hardly ever cooks or does ANYTHING that generates moisture except breathing.
We’re really tired of freezing our fingers & feet even though the heat is cranked & energy audits apparently say our house is doing “fine” in terms of energy usage. And the increase of health issues of both inhabitants makes me suspect wall insulation since it’s supposedly the not-recommended setup. Basement does have stud walls, but that setup is concrete->unfaced fiberglass->plastic->drywall.
