Got a question for the residential guys. I've got 4 recessed lights that I would like to seal up air tight as part of a larger sealing/insulation project on a 1950s vintage home. I'm trying to get the whole ceiling plane as air tight as possible before insulating, & can lights are not helping that.
I think these are IC-rated fixtures (will verify first), and I've already replaced 120W bulbs with LED snap-in downlights at like 20W. Also patched plaster gaps around penetrations.
I see a couple ways to go: Could foil tape & otherwise seal the existing fixtures airtight & insulate over them. Easier, but won't be full depth insulation over fixtures. Also would be a problem if someone sticks a 120W bulb back in there. Or could remove whole fixture and install a regular metal j-box like all the other lights, plaster patch around that. More work of course.
Anybody got any slick ways they retro these? Also, what products do you like for air sealing box penetrations?
Thanks
