Attic Insulation Over Bathroom Fan

I want to make sure that is ok.

Attic insulation over bathroom fan.

Options for venting a bathroom exhaust fan include best to worst. When venting a bathroom exhaust fan make sure to vent the air to the outside rather than into your attic where it can cause mold and mildew to form. The box can be made from rigid foam. Bathroom exhaust fans perform an important function by removing excess moisture from your home.

When i got to my exhaust fan for my bathroom i added that last year i went right over the fan and covered it. If you see that your duct isn t insulated at all pick up duct insulation at the home center. How well the insulation around the bath fan will work depends on the ducting greatly. There are several options available for the ducting like flexible aluminum ducting.

If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct. Always cover the tops of the ceiling joists to make sure the insulation is deep enough to reach your target r value and to prevent thermal bridging the heat loss that occurs through the wood framing. The seams can be taped with housewrap tape. You may find that the insulation simply needs to be refastened.

I had insulation from 1952 that was less than an inch thick. In un conditioned space such as an attic where otherwise your fan duct will be exposed to cold attic air in winter use insulated solid metal ducting or insulated flex duct. I just added r19 unfaced insulation to my attic. The first step is to head to the attic.

Another approach could be an insulated hvac duct approach. Work from the perimeter of the attic toward the door or hatch so that you don t trample all over the insulation you just put in. The exhaust fan housing should be covered with an insulated airtight box.
