Garage attic wall ...common to the house?

The garage is fully sealed with fire rated drywall … the attic space above the garage has a wall common to the house … there are duct openings …
Do openings above the garage … need to be also sealed.

If your second picture is foam board, it will burn. So if it needs to be fire rated, it is not.

And, if your garage is completely sealed, check the attic hatch cover for 1/2" drywall or equivalent.


The answer to your 1st question is no in my area.

Then follow Larry’s advice.
