I’m trying to understand if it is expected to have some thermal transfer from the basement into the garage along walls that are shared with living spaces.
I’ve included three images. The first photo is pre-drywall. I added a red arrow where the heat is leaking out. Below the door is basement where the rim joists are insulated with closed-cell spray foam.
The second photo is post-drywall. I attempted to seal the the gap between the bottom of the drywall and garage slab with canned spray foam.
The final image is a thermal image that shows some heat leaking out of the bottom of the wall.
Is there something that is causing this? The basement walls (concrete) are currently uninsulated.
