Cut batts carefully for a tight fit. Next, staple 4-mil poly to the walls and ceiling. Embed the poly sheeting in caulk around the perimeter of each piece to create an airtight seal. Seal the seams between sheets and seal the poly to electrical boxes with caulk or special sheathing tape (it’s typically red and looks like packing tape).

These two photos show how to add ceiling blocking.

Your garage is an often untouched part of your home. The uncomfortable truth is that far too often it is not used for our vehicles.
