I am currently renovating my bathroom and have run into some question about how to handle the Ceiling. FIRST: My father first suggested that I use BlueDow (blue foam board) on the ceiling under the joists to: 1. hold up the insulation Batts (Roxol 2x6 batts) 2. create a vapour barrier (once...

I am installing IC rated pot-lights into a ceiling of a flat roof house. The vapour barrier boot/bag is much larger than the pot lights. Is it okay to pack out the empty space in the vapour boot with insulation like Roxul?

Just finishing an insulation upgrade in basement prior to adding living space and am wondering about vapour barrier. I always find the joist pockets troublesome to install vapour barrier in and was wondering if it wouldn't be better to vapour barrier the walls up to the top plate of stud wall...

I have been thinking about putting down some laminate flooring in my family room. Looking at the options for underlayment have left me with a question on vapour barriers. The room is high traffic, but we dont spend anytime in it (No chairs) its more a pass through to other areas of the house...

Hello, first let me mention that I've been reading up on a lot of the threads here as a guest and I'd like to say I've always been impressed with all the info and good discussions. I'm a first-time homebuyer in Quebec (Canada) and my house has a semi-unfinished basement ... semi being in that...

I am in the process of figuring out the insulation options for a new construction in a mixed climate (southern BC, snow but not too cold in winter, hot in the summer, raining the rest of the time). I had originally intended on putting 1 inch XPS on the outside of the 2x6 wall (7/16 osb, tar...
