Insulating Attic Over Garage Faced Or Unfaced

When you should insulate the garage.

Insulating attic over garage faced or unfaced.

Because the simplest and cheapest way to insulate an attic is to add material to the floor. Unfinished or uninsulated attics need a layer of protection against air migration. When adding more insulation to an attic that already has insulation use unfaced insulation. But in this application going over other insulation you do not need faced insulation.

If the heat can not escape from the attic it will migrate down into the garage in which case insulating the attic of the garage will help a little. If the walls and ceiling will remain open not covered with drywall or plywood it s a good idea to use paper faced or encapsulated fiberglass bats that are wrapped in a plastic film. Insulation is used reduce the transference of heat between conditioned area your house and non condition areas garage and outdoors. But if the floor is covered in plywood you can t stuff enough insulation beneath it to do the job sufficiently not even in warm climates.

If you do not heat or cool an area it is considered to be unconditioned. As a result of evaporation people breathing and plant respiration air carries some. The same applies to faced unfaced and other kinds of insulation products. For many contractors the decision to use one kind of insulation over the other depends solely on preference rather than a by the book decision making process.

The best choices for this type of application include comforttherm kraft faced or unfaced with a separate vapor retarder film placed over the insulation. You can also get loose fill fiberglass which it suitable for blowing into a garage attic space above a finished ceiling. This can be done through blown in insulation and unfaced or faced batt insulation. What is the right insulation for an attic.

Insulating the attic above the garage will help keep temperatures in the garage a bit more stable but it won t have any appreciable effect on energy bills. After insulating the attic of your garage your garage will be the same temperature as the outside in the shade. To insulate the floor of the room above the garage seal the space between the floor of the room and the ceiling of the garage and the top plate and the header joist with insulation. The facing on the insulation is a vapor barrier it needs to be placed face down.

Before installing insulation in garage walls clear the area inside your garage of any obstacles. Insulate as you would any exterior wall with insulation that includes a vapor retarder. Plan to pull up the flooring and layer new insulation on top of the old. This will serve the same function of keeping hot or cold air inside the garage as it does for the rest of the house.
