Air-Sealing and Insulating Floor Over Vented Crawlspace
I have a 1959 building, with vented crawlspace. Zone 3M. Northern California.
Subfloor is T&G.
Looking to air seal and insulate the floor joist cavities.
Looks like that might be impossible because of all the gaps between each 2×8 T&G board.
I have a 10 MIL moisture barrier on the dirt crawlspace floor.
I was hoping to caulk the inside of the rim joist, and batt insulate the joist cavity. Is this worth it? Looking for something I can do myself, but also will actually be financially wise.
