Air Sealing Electrical Outlet Boxes
Looking for input on what products high performance builders are utilizing to seal around the wire penetration to there airtight electrical outlet boxes located on the exterior wall? I’m noticing some builders / insulators have been sealing them up with canned spray foam which is combustible if a electrical spark every occurred.
Any product suggestions that have worked well for past projects would be appreciated!
