How to Insulate Your Garage

Insulating your garage can actually help the energy efficiency of the rest of your house.

If your garage stays warmer in the winter, then the rooms above it or adjoining it will have an easier time of staying warm too.

Choose insulation with an appropriate "R value." The higher the R value, the better it holds heat in. You don't automatically have to get the highest R value, because some climates don't require it. Just get the highest R value that's appropriate for the climate you live in.

You'll need enough rolls of insulation to fill in between all the wall studs, enough 2 x 4s to span all the studs horizontally three times, a staple gun, nails, plywood, hammer, drill, screwdriver, gloves, and eye protection.

First, staple the insulation in place. It's made to fit in between the wall studs. You want the paper side out, not the pink side. Push the insulation between the studs and staple the paper flaps on the edges of the insulation to the stud posts with your staple gun.

After you have all the insulation stapled into place, put the 2 x 4s horizontally across the insulation and studs at the top, in the middle, and toward the bottom. Nail them in place onto the studs. Once you have all the 2 x 4s in place, nail the sheets of plywood, with the A-grade side out, to the 2 x 4s. Once they are nailed in place, use screws every 12 inches to secure the plywood.

If there are windows or doors in the wall you are insulating, you'll have to cut out sections of plywood to accommodate them.

Instead of plywood, you could use drywall for this project. Reasons for choosing plywood over drywall in this case include: plywood is lighter to work with and if you choose to install cabinets or shelves in the future, they'll be easier to put up over plywood.

So there you have it, not so difficult but you will be glad you did it and at the same time you have some extra savings for some good old Tim Hortons Coffee to keep ya comfy while the car warms up!
