I have a bathroom exhaust fan that is vented directly into the attic.
Attic insulation around bathroom exhaust fan.
Water stains on the ceiling around your bath fan may indicate a leak coming from the vent cap on your roof but condensation is the more likely culprit.
If you take it through the roof using a metal pipe do you use insulation around the pipe.
The job of a bathroom exhaust fan is to remove moist air and foul odors from the bathroom.
The first step is to head to the attic.
Home bathroom bathroom exhaust fan.
Insulate the bathroom exhaust vent fan ducts.
When moist air is carried through a duct that passes through a cold attic space condensation will occur.
Bathroom vent fan ductwork insulation.
The duct runs in my attic above the bathroom ceiling two story home.
What is the best thing to do to correct this problem.
I used flexible 4 aluminum duct to the exhaust damper on the roof.
I recently installed a bathroom exhaust fan.
Insulation problems will lead to other problems like the fan not being able to extract any humidity from the bathroom at all.
T he result of the insulation problem around a bathroom exhaust fan is either water stains or mold near the vent of your bathroom.
Keep calm if that happens to you.
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.
In existing homes air seal and insulate around new or existing bathroom and kitchen exhaust fans to minimize air leakage to and from unconditioned attics.
If bath fan ducting isn t properly insulated the moist air from your house will condense inside the duct.
Remove insulation around the exhaust fan on the attic side.
