Hello! I was wondering if anyone had any advice or experience regarding putting a bathroom extractor fan in a timber framed house please (also considering one for the kitchen as well). I understand you are not supposed to put things through the walls (vapour barrier etc), does anyone have any suggestions / recommendations / experiences? I believe one option (for the bathroom) would be to vent through the roof via a vent tile but I have read stories that this set up isn’t always successful due to condensation running back down the vent pipe work. Ideally I would prefer going through the wall but unsure about whether that causes issues with breaching vapour barrier and cavity. Won’t be doing the job myself but want to know what best practice is before I find someone to do the job. Thank you in advance
