Should wall mounted extractor fans use ducting?
I have an extractor fan in my downstairs toilet and the kitchen but I noticed there is no ducting between the inside fan and the grill on the outside.
There is a ducting shaped hole behind each fan.
Not sure if this is an issue with regard to moisture etc.
Thanks
