If you would like to have a place that you can get out of the house, you can set up a man cave in your garage. You can even put a television and a comfortable chair out there, a bar, or a nice work area. Whatever you choose, you need to make sure you stay warm in the winter. The best way to do this is to insulate your garage.
Before you start insulating your garage, you need to make sure there are no cracks or any gaps in the walls in case any air leaks out of them. Some common places you should check for gaps are the window and door frames and around electrical outlets. If you have a dryer in your garage, you should check the dry vent that passes through the wall.
Purchase cans of air sealant at a home improvement store, and spray it into all cracks, gaps, and holes until everything is sealed up tight. Follow the directions on the air sealant can on how to properly use it.
Purchase some fiberglass batt insulation at a home improvement store. It usually comes in rolls that you will have to cut to size. Just make sure they are long enough to fit the spaces you are filling. Read the installation guide before you install the insulation so you will install it correctly. Mistakes you may make are failure to securely fasten the insulation to the wall, or cutting it too short or too long for the space. The insulation needs to fit snugly into the space, but it should not be pushed in too tight.
Insulate the Attic
If you heat or cool your garage, you should consider insulating the attic so your hot or cool air does not escape. If you do not use any kind of heating or cooling in your garage, then there is no need to insulate the attic space. If your attic does get very hot in the summer, however, insulating it can reduce some of the heat that comes from the attic into your garage. Hire a home energy auditor to help you determine if you should insulate your attic.
If you choose to insulate it, you can use fiberglass insulation or use blown insulation. It is much easier if you choose to blow it in, because you won't have to carry rolls of fiberglass insulation up to the attic.
If you choose blown insulation, you can choose between cellulose or fiberglass insulation. The main difference between these two types is cellulose is dusty, and fiberglass insulation is itchy. Either one will work as good as the other.
If you do not feel comfortable installing the insulation in your garage, hire an insulation contractor like All Weather Shield Inc to do this job for you.
