Extractor fan ducting

needsomeadvice · May 1, 2019

Hi all

Have an en-suite that needs a shower light extractor combo fitted. Can’t fit the ducting grill outside due to grade 2 listing.
Does anyone know of an alternative for the ducting to extract the moisture/air.
The ducting will be going into the loft area.

Thanks

Might want to consider insulated ducting to avoid condensation and dripping from the fan.

May want to look at what the maximum length of flex duct is according to regs. 1.5m max. Plus need to check building regs on ventilation too to check that your planned fan is sufficient may need to run constantly and speed up on bathroom usage etc etc
