Panasonic Bath Fan: IC OK?
Maybe a simple question:
I’m installing a Panasonic Bath fan into my existing bathroom ceiling. There is a lot of cellulose on the other side of the plaster. Is it OK for the fan to be partially/completely buried in cellulose?
The access above the ceiling is very tight due to low slope rafters, I can’t really get to it from above. Existing construction is plaster/lath on ceiling joists. I’m adding a new layer of 1/2 drywall over the plaster, so I can tear up the plaster where I need (fan housing location and then another access where the exhaust will vent through the wall about 4 feet away.
Is there a trick to dealing with the loose cellulose as I cut my holes in the ceiling? Or should I just prepare for a snowstorm and replace the cellulose as best as I can afterward?
It should say, but bath fans are typically rated for direct contact with insulation.
As for the insulation, you could try making a smaller hole to start and then using fiberglass insulation as a dam to keep the cellulose out of the way.
The Panasonic fan I just installed (light and fan, no heat) specifically says it is IC rated)
