Attic Insulation Over Bathroom Fan

I had insulation from 1952 that was less than an inch thick.

Attic insulation over bathroom fan.

When i got to my exhaust fan for my bathroom i added that last year i went right over the fan and covered it. 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. Insulate the bathroom exhaust vent fan ducts. If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct.

I want to make sure that is ok. Another approach could be an insulated hvac duct approach. You may find that the insulation simply needs to be refastened. 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.

I just added r19 unfaced insulation to my attic. Caulk or spray foam can be used to seal the box to the ceiling drywall and to seal around the exhaust pipe. The first step is to head to the attic. There are several options available for the ducting like flexible aluminum ducting.

Bathroom exhaust fans perform an important function by removing excess moisture from your home. Options for venting a bathroom exhaust fan include best to worst. The seams can be taped with housewrap tape. The exhaust fan housing should be covered with an insulated airtight box.

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. How well the insulation around the bath fan will work depends on the ducting greatly. The box can be made from rigid foam.
