Brent writes from Sebring, Florida: "Have a un conditioned garage below conditioned living space. Have about 18 - 24 inches between garage ceiling and floor above, should the insulation be installed up against the above conditioned living space kraft paper up as well, or insulation on the sheet rock ceiling of the garage with kraft facing up?"

Answer: The insulation should be installed up against the conditioned living space. Installing it under the sheet rock will result in your conditioning the space between the floor above and the sheet rock below. It will also risk having opportunities for air leaks. Since the garage is unconditioned, the paper should face up towards the living space.
