Garage Attic Insulation Faced Or Unfaced

To this end you insulate your home.

Garage attic insulation faced or unfaced.

Before installing insulation in garage walls clear the area inside your garage of any obstacles. Paper faced insulation means that one side of the insulation material comes lined with paper. If the attic doesn t have any existing insulation use faced insulation with the paper facing toward the heated living space. However if your garage already has a layer of insulation use unfaced insulation.

Among the many insulation options available for the homeowner there is one that stands above the rest. Facing is a thin layer of paper or plastic attached to one side of batting insulation which is sold in a roll. Facing is a layer attached to roll or batt insulation as a vapor barrier to help protect the living space from excess humidity or moisture. But in this application going over other insulation you do not need faced insulation.

The primary reason to insulate any part of the home is to provide a thermal barrier between conditioned heated or cooled interior space and the outdoors or unheated spaces such as an unfinished. This is usually kraft paper but sometimes other types of paper can be used. The best choices for this type of application include comforttherm kraft faced or unfaced with a separate vapor retarder film placed over the insulation. When local building codes require a vapor retardant faced insulation is one of the best options.

The kraft paper itself is highly flammable. 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. Generally you should use faced insulation for your garage especially if you live in a very cold or humid climate. The kraft paper on one side of faced insulation keeps moisture from spreading throughout the walls or ceiling.

However there are also insulations like spray foam insulation that is designed to be moisture retardant anyway when facing isn t required. Using faced insulation may help you comply with your local building codes. When adding more insulation to an attic that already has insulation use unfaced insulation. You can also get loose fill fiberglass which it suitable for blowing into a garage attic space above a finished ceiling.

Insulate as you would any exterior wall with insulation that includes a vapor retarder. It is basically designed to keep drywall dry.
