Can I add insulation to my garage?

Can I add insulation to my garage?To save on energy costs, most people strive to insulate their homes effectively. However, many homeowners do not even consider the benefits of insulating a garage. The type and amount of insulation for a garage depend on how the garage is used and if the garage is attached to the house or stands alone. The short answer to this question is that you can insulate your garage. Read on to learn more below.

Unfinished Interior Walls

Insulating garage walls not covered with drywall is easy. It is just a matter of deciding to do it. Most garages are framed with 2x4s and are 16 inches center-to-center. This is the perfect size for laying in readily available 15″ wide R13 Fiberglass Batt Insulation. Since garage heights vary considerably, sheets of appropriate lengths will have to be cut from insulation rolls and hung. Before the insulation is installed, take the opportunity to have any gaps in the walls foamed to stop air leaks. For interior walls shared with the home, this is especially important for keeping garage smells from creeping into living areas. The insulation may also help slow the spread of fire from the garage to the house.

Finished Interior Walls

In order to use relatively cheap rolls of the 15″ wide R13 Fiberglass Batt Insulation, drywall will have to be removed. Or alternatively, you can cut a series of holes in the drywall and use Blown-In fiberglass or cellulose. After the insulation is in place, drywall patching will fill in the holes.

Attic Insulation

Often times, a garage has a roof over it, so the attic of the garage is an important place to include. And it is a lot easier to insulate than the walls. Batt, Blown-In or Spray Foam are the most effective for the garage attic use. It is especially important to insulate the garage attic if you are using a heater or air conditioner because the insulation will help keep the hot air out of the garage in the summer and the warm air in the garage in the winter.
