Attic electrical outlet sealing

Nov 29, 2006 7 Replies

I recently put up a ceiling fan and felt a lot of cool air coming around the ceiling outlet. What is the best way to seal ceiling outlets? I currently have 12" of blown in fiberglass. A friend suggested a cap to go over the outlet but I have not been able to find one at lowes & home depot.



Any suggestions??


Perhaps try a "real" building supply outlet? An electrical supply house might have them too, call around.

If you can't find them you can always cut some regular 4 mil plastic sheeting to rest over the box in the attic and duct tape it to the sheetrock and then put the insulation back over it. If it's a ceiling fan box there won't be any heat issues like there are with recessed lights.

Why not just put a sealing gasket on it?

Foam it in with spray foam. That is what the builders use for draftstopping.

Bury it in great-stuff, from the attic side.

I did this myself, went around fan boxes and made a igloo of expanding foam around it, and once cured, moved the insulation back in.

It works for me, but then that is me. :)

later,
