Fair point! With the right products installed well, it doesn't necessarily need to be smelly and damp either! Unfortunately too many aren't finished well. Thanks for watching
i'm in the GTA, thinking, from the cinderblock wall: R24 roxul in 2x6 size but use 2x4 studs 1.5" off the wall. intello or certainteed membrain. wood paneling. done. yes?
I would suggest putting 2" of rigid insulation on the foundation wall before framing. If you use XPS you can tape the joints. You could spray foam the headers after that too so it ties the XPS from the wall to the headers. This improves the air tightness. Then you could frame a 2x4 wall in front of the foam with R-14. More actual R-value (because of eliminating thermal bridging), better airtightness and a thinner wall assembly. You can still use the Intello Plus but you don't have to worry about taping the joints anymore with this assembly as well!
@@Theconsciousbuilder Thank you, I do appreciate the thoughtful reply! If I may... After seeing ants chewing and depositing purple Walltite sprayfoam into the living space of my previous home, and learning that they also make homes in the XPS I had put exterior in ground before backfilling a waterproofing job, I became a Roxul fan. Also because of the embodied carbon of foam / petroleum product nature, I'd prefer not to use those products. On a single income, so hoping for 'pretty good' over 'best possible' while not creating a moisture trapping assembly... Thanks again, I really appreciate the channel and building science infused throughout!
So if the basement has good insulation, drainage and moisture management (all exterior) plus dehumidifier in the basement then it should be fine, right? To me that says basements arent necessarily a "bad idea" they just need to be built correctly, like everything else in the home.
