Step 1: Cut the Foam Insulation

Measure and cut foam insulation to cover the outside of the cabinet shell. Use a chalk line to mark the cut lines, and then cut the insulation with a circular saw.

Tip: When installing cabinetry or other built-in storage in an attic, it's important to insulate it to protect the contents and prevent heat loss in the room.

Step 2: Secure the Insulation

Secure the foam insulation to the outside of the cabinet with adhesive. Reinforce with a few screws.

Step 3: Transfer the Measurements

At the wall, measure the distance from the sides of the opening to the roof studs. Use a pencil to transfer these measurements to the cabinet.

Step 4: Slide the Cabinet Into Place

Tip the cabinet forward. Lift it from underneath and slide it into place so that it is flush with the wall.

Step 5: Secure the Cabinet

Drive screws into the roof studs from the inside of the cabinet to hold it securely in place.

Step 6: Install the Trim

Measure, cut, prime and paint the trim to surround the outside edges of the cabinet. Install the trim to give the cabinet a finished look. Touch up paint on the walls and cabinet.
