How To Insulate A Garage Ceiling Already Drywalled

Garage ceilings are often neglected when it comes to insulation, yet they can be a major source of heat loss and energy inefficiency. Insulating your garage ceiling can save you money on your energy bills while also making your garage more comfortable to use in both hot and cold weather.

If your garage ceiling is already drywalled, don't worry! There are several ways to insulate it without having to remove the drywall. One option is to use spray foam insulation. Spray foam is a type of insulation that is applied as a liquid and then expands to fill the space around it. It is an excellent insulator, and it can also help to seal any gaps or cracks in the drywall. Another option is to use fiberglass batts or rolls. Fiberglass is a less expensive option than spray foam, but it is not as effective an insulator. However, it is still a good choice for insulating a garage ceiling, especially if you are on a budget.

If you decide to use spray foam insulation, it is important to hire a professional to do the job. Spray foam insulation is a hazardous material, and it can be dangerous to install if you do not have the proper training and equipment. If you decide to use fiberglass batts or rolls, you can install them yourself. However, it is important to follow the manufacturer's instructions carefully to ensure that the insulation is installed properly.

Here are the steps on how to insulate a garage ceiling that is already drywalled using fiberglass batts or rolls:

Measure the length and width of the garage ceiling.
Cut the fiberglass batts or rolls to fit the ceiling.
Place the fiberglass batts or rolls between the joists in the ceiling.
Secure the fiberglass batts or rolls in place with duct tape or staples.
Cover the fiberglass batts or rolls with a vapor barrier.
Tape the vapor barrier in place.

Once you have insulated the ceiling, you will notice a significant difference in the temperature of your garage. The garage will be cooler in the summer and warmer in the winter. You will also save money on your energy bills.
