Bathroom vent fan duct installation & routing suggestions begin just below at BATHROOM VENT DUCT MATERIALSBathroom vent fan duct materials: flex duct vs solid metal Flexible plastic vent fan ductwork: shown at above left is a common use of un insulated, flexible ventilation fan duct. In this installation the duct is improperly installed, spilling directly into the attic space of the building. This duct material is least costly at the time of installation but may be most costly when a combination of accumulated condensation and duct damage leaks into the building insulation or ceiling cavity. Flexible metallic exhaust fan ductwork: shown at above right is flexible metal exhaust fan ductwork. This material is more smooth- surfaced than the plastic product shown at above left and by its flexibility, can eliminate the need to install many elbows in the system.
The installation shown is too long and should have been insulated. Metal vent ducts: kitchen vent fans require, and good bath vent duct design also uses solid metal ducting, not flexible .

The ceiling cavity between the I- Joists was later insulated with solid foam, as shown at above right. Because this is a sloped cathedral ceiling it was not possible to slope the fan ductwork back down towards the shower below the fan. Instead we vented this fan out through the soffit in the roof eaves. But flex duct and insulated flex duct are approved by bath vent fan manufacturers are very widely used for fan venting. Question: using spray foam to seal around a bathroom vent fan(Mar 1.
John said: Hi. I sprayed insulation foam ( not the fire block ) around the bathroom vent fan in an attempt to seal small air leak from the attic . Is this a fire hazard ? Thank you. Reply: John,You should be OK if - the following: - foam did not enter the fan enclosure- the fan installation data including stickers inside the fixture specify that it can be installed in direct contact with building insulation. I'd have preferred using a fire- resistant foam, but if the above conditions are met you should be ok.

The vent run needs to be designed to drain any condensate outside not back into the bathroom ceiling; in a freezing climate I'd insulate such a vent line as well; If we run a bath vent vertically up through a roof we have two risks I'd prefer to avoid: A vertical bath exhaust fan duct run guarantees that any condensation runs back down into the fan (risking damaging the wiring or fan motor) and back into the bath or bath ceiling. The vertical run also means another roof penetration. I prefer to minimize the number of roof penetrations on any building since every penetration is a potential leak point, more so if the penetration flashing is not installed correctly.
