Hey all, I just bought a house and there is no exhaust fan in the Bathroom. I'm going to install a light/fan combo so I was crawling around the attic to map out my exhaust options. I have to cut the vapour barrier in the attic in order to mount the fan box but am a little wary it could be bad to do that. any advise on how to deal with the vapour barrier so it still serves its purpose once the exhaust is installed. Thanks for any tips you guys/gals can provide!
