Unroll the batting. Measure the opening between the studs along the open-faced wall and cut the batting to fit with a utility knife. If your garage walls are already covered with drywall, then they are probably already insulated. You could drill into the wall to make a small hole so that you can see if insulation is present. If the walls are covered and no insulation is behind the drywall, it isn't cost affective to remove the drywall. It is better to contact a company to fill the insides of the wall with a loose-fill insulation.
Place the batting in between the studs so that the vapor barrier facing is against the outside wall. The facing is basically a smooth covering over one side of the batting. Staple the batting to the studs through the tabs on the sides of the insulation. Do not put batting around fire hazards such as electrical outlets. Keep the batting at least 3 inches away on all sides of these areas.
Measure the opening between the ceiling joists and cut the batting to fit with a utility knife. Install batting in between the joists, stapling to the joists in the same manner as you did on the walls. You might need help holding the batting up while you work. For added support, run lines of wire at a right angle to the ceiling joists every two or three feet. Secure each line by wrapping it around screws as you stretch it across the area. Insert the screws with a drill so that 1 inch is sticking out of the joists.
Place the freezer as far away from the large garage door as possible. The garage door will let in quite a bit of heat in the summer when it is opened and closed, and it is best for the freezer to be as far away as possible. The door itself will transfer heat in when it is closed, unless it is an insulated door. For better results, consider having an insulated door installed.
Set the freezer on a level spot near an outlet and plug it in. Let it run for several hours before putting food in it. Do not fill it full all at once, or it will have to work overtime to freeze it all. Place 1/4 of the contents in and wait a couple hours. Repeat until it is full.
Things You Will Need
- Batting insulation
- Staple gun
- 3-inch screws
- Avoid opening and closing the garage door unnecessarily. Insulated garages only work if they are closed off from the heat. Leave cars outside during the summer until they cool down after the sun has set, then move them inside. Cars put off heat that might make the garage too warm.
- It is best to cover insulation when you are through installing it. Use paneling or drywall to cover the stud framing.
