How to Put Insulation in a Garage

Installing insulation in a garage can be done fairly quickly by about any handyman, and getting started is easy. Select the type of insulation material that will work best for your type of garage construction. A few types which are available include foam panel, batt and loose-fill. Purchase any additional supplies and you are ready to get started.

Installation tips:

Step One

Foam panel insulation is usually installed on drywall, metal or masonry walls.

1) Lay the panels out, measure and trim to fit the wall. This can be done with a razor knife.

2) Spread epoxy on one side of the panel and place the glue side against the wall.

3) Continue repeating the process until all the garage walls are covered.

Step Two

Batt is roll insulation most often installed in walls that are not yet dry walled.

1) Unroll the insulation, measure and trim to fit between the studs in the existing wall.

2) Place the trimmed insulation piece between the studs and tack in place with a small nail.

3) Once the insulation is in place, hang the drywall and nail it to the stud.

4) Repeat the process on each of the garage walls.

Step Three

Loose-fill insulation is usually installed on walls where the drywall has been finished. It is a bit trickier to install because it requires a blower to spray the insulation into the wall.

1) Obtain the insulation blower from a home improvement store.

2) Recruit a friend to help with the project. Spraying insulation into a wall is a two person job. It requires one person to spray the insulation into the wall, while the other feeds the blower's hopper with the insulation product.

3) Set up the machine by loading the machine's hopper with your chopped insulation product and attaching the hoses and nozzle.

4) Locate the studs in your garage walls with a stud finder.

5) Carefully, make an opening in the top of the drywall with a razor knife about 3 x 3 inches and remove the piece. Set this aside, it will be reinstalled later. This will be done between each pair of studs.

6) Start working by inserting the blower's hose and nozzle into one of the holes.

7) Start the machine. Spray the insulation downward between the studs.

8) Repeat this process around the entire garage until insulation has been blown into each pair of studs.

9) Reinsert the removed pieces of drywall patch and paint.

10) The job is complete.
