Using white duct tape because the tabs don't hold well is the primary negative response I've read. Which would honestly be fine by me.

This insulation business just got more complicated. See, my house originally had the whole garage under the master and third bedrooms. That garage was sectioned in half with the forward half being turned into an office. It appears that they did insulate the office area when they did this work.

Eventually, another garage was built onto the house and isn't under anything. So I have a garage and a half. The new garage doesn't appear to have insulation on any of the walls. There's no insulation in the ceiling of the old garage either. This leaves the floor of the master without any insulating barrier except for whatever the sheet rock and exterior brick walls of the garage provide. Guess I'm looking into DIY spray in insulation options now.

Thanks Mitch. I appreciate the feedback.
