insulating drywalled garage


my attached is already drywalled but not taped .I plan on having a heat source to be used occasionally.
Do I need vapor barrier in the ceiling ?
If so should I pull down the existing drywall and start from scratch?
I plan on stripping the walls to insulate the walls properly looking for the right way to tackle the ceiling
thanks Tony

Welcome to the forum!

Where are you located?

Many times just a v.b. paint primer is added rather than removing material.

insulating drywalled garage


I am located in the valley area of Nova Scotia where we have a variety of weather . The house is a bungalow with an attached garage . There is just attic space above the garage . My concern is if I Insulate it with cellulose do I need to use vapor barrier if I chose to heat the garage on occasion .
With drywall on the ceiling and two garage door openers I'm debating on ripping it all down or just fill the roof trusses with cellulose .
Opinions welcome

If you don't need the storage, use cellulose. Anything is better than no insulation. Your area ranges from 3800-4700 H.D.D. It's not a house so the minimum R-value doesn't apply. I'd dense pack the walls and blow-in 2# in attic, no v.b. required; http://www.applegateinsulation.com/C...id=249418&fd=0

Make sure the drywall will support it; http://www.energyguide.com/library/E...SubjectID=8375
