Step 1: Staple the Insulation Into Place

Insulation is typically made of spun fiberglass. Push the fiberglass insulation between the studs with the paper side out (Image 1).

Staple the paper flaps, which are on either edge of the insulation, to the stud posts with a staple gun (Image 2).

Tip: Use an insulation that is appropriate for the project. The higher the number, the better it works. R-13 was used in this project (Image 3).

Step 2: Add 2x4s and Plywood

Place 2x4s over the top of the insulation, spanning the studs (Image 1). Nail the 2x4s into place.

Nail the covering sheets of the plywood to these (Image 2).

The 2x4s are needed to bump out the flywheel so it will be even with the concrete footer.

Step 3: Secure the Plywood

Secure the plywood with the A-grade side facing out. Space screws every 12" (Image 1).

Cut the plywood to fit around the doors and windows (Image 2).

Drywall could have been used to perform the same function, but plywood was used because it is lightweight and durable. Also, cabinets will be covering the wall later, so there is no need to tape and mud, which is commonly the procedure when working with drywall.

Step 4: Cut Weather Stripping for the Garage Door

Remove the existing weather stripping. Next, measure the difference between the door and the concrete.

Cut a strip to fill the uneven gap between the floor and garage door using a circular saw.

Step 5: Secure the Weather Stripping

Secure the strips with glue and screws (Image 1).

Once the door is level, install a new plastic weather strip with nails (Image 2). Cut the remainder of the strip with a utility knife.

For added insulation, install a flexible weather seal around the exterior of the garage door.
