How to insulate/seal in tight spaces
Hi, I've got about 14" where the ground floor was bumped out 2.5" over the walkout basement. The joists run perpendicular, so there are about a dozen little "bays" roughly 30"x14" where the outside ir circulates and makes it feel like you're stepping on a slab ice in the kitchen above. I've caulked outside, but bridging fitted at the openings to the basement, along with various wiring runs and vents make it virtually impossibly to get a caulk gun or expanding tape into all the corners inside the bays. I was going to use expanding foam, but when I found out it's VOCs, I didn't like the idea of having those gases circulating through the room, which is the laundry room, and into the rest of the house. Has anyone found a sealant to use in tight, inaccessible places, or do you just stuff it with formaldehyde-free insulation (my current solution, using recycled denim)?
Appreciate your thoughts!
