Insulating Garage Ceiling Vapor Barrier

Not every wall does.

Insulating garage ceiling vapor barrier.

You can forego the plastic and use a vapor retarder kraft faced insulation or latex ceiling paint in all other climates except hot humid or hot dry climates. Whether your vapor barrier is a facing or a film it must be placed on the warm in winter side of the wall. My main goal is to keep it from getting much below freezing during the winter. Install as directed typically cutting to fit and using a staple gun to attach the vapor barrier to the studs.

Vapor barriers keep the air moisture in your house from condensing in the insulated cavities. A vapor retarder is a material used to prevent water vapor from diffusing into the wall ceiling or floor during the cold winter. In reality insulation merely slows the transfer of heat through the insulated barrier wall ceiling floor etc. If you live in a cold climate place the vapor barrier between the interior of your home and the insulation.

I m considering insulating and drywalling my garage which already has insulated garage doors. In hot humid climates attics should not be vented and vapor. If you re adding new garage doors be sure to install insulated options. There is a school of that maintains that an unheated garage that is attached to the house may get some benefit from insulating the walls and ceilings of the garage since it theoretically offers an additional thermal buffer.

When the house was built 10 years ago the walls attached to the house were done and the ceiling was drywalled fire code. If you re using old uninsulated doors pick up a retrofit kit that add insulating panels. Plastic vapor barriers should only be installed in vented attics in climates with more than 8 000 heating degree days. After the insulation is in place you will want to add a vapor retarder sometimes called a vapor barrier if you need one.
