And...if you want to get really "scrutinize-ding" Is that really a word?? You wont get a vapor barrier on a lot of places besides the studs. The joists and box areas between the floors never have it. And any outlets which get cut out...all throughout the outside walls. Moisture will evacuate itself from the house. This Kraft faced paper just helps to collect it and actually store some moisture and release it as it needs to.
A house will breath, that is why I disagree with plastic on the inside of homes. It will not let anything through...at all ,and will collect at the bottom of the sheet. I have fixed to many new homes were they have humidifiers in the system which are doing nothing but causing serious damage , and health concerns. All because of plastic vapor barriers.
Do it like Square Eye and I suggested and be done, then enjoy the greater comforts of home.
Probably over 40 years of experience between the 2 of us. I'm on 24 myself at 40 years old.
Still young enough to boast about it, and old enough to know I'm just foolin myself.
