Garage insulation

Army80

I'm Renovating my garage. I have a question regarding the insulation in the ceiling. I have a bedroom above the garage... There is Insulation between the joists but no vapor barrier. Where does the vapor barrier go? On the warm or cold side? If it's the warm side how would I ever install it now?

Welcome to the forum! Why do you suspect you need a vapor barrier?

Where are you located?

You should have 5/8" drywall Type X for fire stop installed already......

The previous owner installed 1/2" drywall in my garage. Did a horrible job at that. I removed it all today. I noticed no vapor barrier. I thought it was a requirement. It does get quite cold in the winter in the bedroom above. I am located in Toronto. I'm thinking about spray foaming it.

I hope you are not driving while.....

I would check locally, you need to know exactly what is required. I'll guess: Type X gypsum with a 6mill. barrier on the heated side. Foam will satisfy the B.D. depending on thickness for your Code.

Hi,

Did you end up spray foaming? If so, did you do yourself or contract this out (may be a silly question since this is the DIY chatroom)? I am also experiencing cold in a kitchen over the garage. I want to re-insulate, thus doing some research.
