Bonfiglioli Wall for remodel in 2023
Did some searching but not too much pops up in terms of real world feedback on the Bonfiglioli wall…
Was wondering if there is any consensus on this for 2023.
Just bought a new house and will likely gut most rooms to the studs. House is about 50 years old in Wisconsin, about 1600 sq ft., zone 6B, and has 2×4 framing with R-13 fiberglass between studs.
Plan is to add 1 to 1.5″ of polyiso strips to the studs and cover with 3/4″ Advantech strips, all from the interior. This would allow me to use 2×6 (5.5″) insulation to help bump up the overall R-factor of the wall.
I do worry about the “squishiness” of the foam and how it might lead to a wavy wall, but I can’t find much real world experience and feedback on the whole process, start to finish, on here or other sites.
For what it’s worth, I completed a DIY deep energy retrofit of another (similar) house recently where I took everything down to the studs, removed all the exterior siding, and added 2″ of polyiso to the exterior. Did airtight drywall, tons of air sealing, tapes, etc. This current house won’t have siding removed so trying to tackle everything from the inside.
Just hoping someone who did this can share thoughts on if the labor is worth it, and if the energy savings (I know the math can get complicated and hypothetical) makes this all worthwhile.
Thanks in advance!
