Sealing bathroom exhaust fan

Hiya,

The last owner of my home cut a bigger whole for the upstairs bathroom exhaust fan and heat radiates into my home through the unsealed portion. What can I use to seal it up? I'm guessing that foam insulation out of a can?

Thanks!

The foam will work but you need to be carefull - if it expands too much, you might damage the fan.

Does the fan not cover the entire hole? Would joint compound and tape make it look better?

Thanks for the reply. Well the fan is enclosed within a box so the foam would probably OK as long as it is safe. the cut out isn't that much bigger and there is a grill on the ceiling of the bathroom so patching it up really wouldn't make a noticeable difference. I'd rather do the quick and dirty here as long as it's safe

use the DAP latex foam in a blue can, normally over near the caulk. Much better than the "great stuff"
