Quote: Anyways they built a garage under a living space and they now wish they would have made a few corrections..Insulate the heck out of the area between the garage and rooms above..Not only for fumes but if they are bedrooms above you hear freaking everything that happens in the garage when trying to sleep.
To keep the floors warm and the noise down--I had the entire space of the floor trusses blown full of sound deadening insulation.
Did you hang the sheet rock on the garage ceiling and then blow in insulation from above?
