Sealing exhaust fans

NormanWB | Posted in General Questions on

Most exhaust fans you get from Home Depot have tons of places for air to leak through. Is there a good way to seal these or are there better fan options out there?

    If you are willing to invest a little more for a fan -- more than the cost of a bargain fan from Home Depot -- buy a Panasonic fan. Panasonic exhaust fans are quiet and energy-efficient.

    If you want to do a good job of installing a fan -- any brand of fan -- make sure that (a) you have caulked the crack between the housing of the fan and the ceiling drywall, and (b) you have sealed the seam where the ducting is attached to the fan with high-quality tape.

    If, when you test the fan, you feel air leaking out of any seams in the fan housing, these air leaks can be sealed with high-quality tape.
