I believe there is an air space in there with a return air for circulation. I could be wrong but that's what I saw when my house was being built. If its cold in that room I would try putting insulation behind the plugs. That did wonders for me. Don't use wall installation they have kits at the store that are already cut out in the shape of plugs. I also tapped up all the duct work seems in the basement. That room is now the warmest in the house. Some caulking around windows is good too.

I also insulated the garage door that helped a lot.

My garage ceiling is insulated, its agaisnt the roof of the garage and then there is an airspace above it and then the floor

Hi Zeeshan

Absolutely there should be insulation between your bedroom floor and the garage ceiling. The latest version of the Ontario Building Code calls for R25.

I've got a dropped ceiling in most of my garage. I would imagine that they didn't insulate the entire void in that ceiling (otherwise the insualtion would be 24" thick). Maybe you have the same thing. If you just break the drywall the insulation may not be right up against it but if you look further in, you'll see it.

If your home is new, then there should be spray foam insulation on the underside of the floor above the garage. There will also be an air space just above the drywall on the garage ceiling.

But, you should not be cutting holes in the garage drywall unless you intend to repair the holes immediatly. This is a gas-proofing issue and a hazard.

Even though the floor above the garage is insulated, it will still feel a bit cool. Consider this - Most bedrooms over garages of detached homes are at the corner of the home. Therefore these rooms have 2 exterior walls, plus the attic that is cool, and a floor that is cool. Of the 6 surfaces in these rooms, only 2 face interior, warm rooms.

Most bedrooms over garages have an air-return in them to help with this situation.
