Faced Or Unfaced Insulation In Attic Over Garage

Add vapor retarder to avoid problems arising from the condensation of water droplets on it especially during winters.

Faced or unfaced insulation in attic over garage.

The kraft paper on one side of faced insulation keeps moisture from spreading throughout the walls or ceiling. The good news is that the solution to your problem isn t that difficult. The kraft paper itself is highly flammable. Simply peel the facing paper off the top layer of insulation.

To make things safe cover your unfaced insulation with drywall to prevent the risk of a fire. If the attic doesn t have any existing insulation use faced insulation with the paper facing toward the heated living space. 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. Staple it into place by tacking every eight inches or so and take care not to tear away the facing of the insulation.

When local building codes require a vapor retardant faced insulation is one of the best options. As you ve discovered since you already had insulation in your attic the layer of new insulation you added should have been unfaced to prevent moisture from becoming trapped between the layers. You should only use faced insulation as the first layer of insulation. When adding more insulation to an attic that already has insulation use unfaced insulation.
