Perfect!! Thanks for clarifying this...I'm sure lots of people are confused about how to do this right!! All set!!!
-
@PeterPug007 Yes, that's correct.
-
So are you supposed to put a moisture barrier against the concrete then finish with a vapor barrier against the insulation on the warm side??

@psandbergnz I hope that this makes things more clear for you. These are confusingly similar terms and are commonly mixed up by many DIY people.Please keep watching my videos and checking out the web site as well.Thanks for the comment because I'm sure you were not the only one not clear on this.

I guess I was definitely confused! So, no danger by putting poly on both sides!!??
I've seen some videos where they put the barrier against the concrete...everyone commented that this was very bad to do and would be possible mold trap!??

@PeterPug007 If you have access to a copy of the "National Building Code of Canada" look up 9.13.2 and 9.13.3.3. These give the rules for interior damproofing of walls and material standards. It's there in black and white and required by the building code of Canada.

I'd love to but I can't seem to find anyone who sells a poly MOISTURE barrier. They keep telling me it's the same as a vapor barrier which thanks to you we now know that's NOT true!! :)
Where can I source this product out?? I'm in Quebec, Canada.
Thanks!

@PeterPug007 The product you use is the same poly for both the air/vapor barrier (placed on the warm side of the wall)and the moisture barrier (placed against the concrete wall). Sorry if I have confused you. So just to be clear you are using the same product (poly sheeting) to do both jobs.

Great! Thanks! If I didn't use a moisture/humidity barrier, what other alternative is there? I heard that you should not have the fiberglass in contact with the concrete wall? Is that true? Keep up the good work...one of the best vids out there!! Regards, Peter

@PeterPug007 I solely recommend what you see in the video. Insulation against concrete allows it to get wet if any moisture or frost is present. The only way around this is to have spray foam insulation sprayed directly onto concrete surface. Thanks for watching and check out our DIY spray foam insulation video if you're interested!
