How To Insulate Your Garage


Those who have it done will attest hands-down: insulating your garage is worth it.  
“Why would I want to spend money insulating my garage?” you might be thinking.
Because, as little time as you may be in your garage compared to the rest of your house, the fact is, you do spend time out there. Whether it is the few seconds you spend leaving your home and walking to your car, to using it as a working room or a home gym, insulating your garage finishes the room to make it a comfortable space.
You also keep many items that are valuable and essential to taking care of your house, in your garage.
Finally, insulating your garage is a smart way to manage your heating and air conditioning monthly bill.
In order to prevent heat and cold air (not to mention gasoline and car fumes) from seeping through the walls and into your home, you need to air seal the wall cavities between the garage and walls that are connected to your home.
Air sealing the walls is cheap and easy. All you need it a couple cans of insulating foam sealant and a tube of silicone caulk.
First, examine your wall. Look for any obvious holes, gaps or cracks like those usually left over from electricians and plumbers. Any holes where electrical wires or plumbing pierce through the wall need foam insulation over them.
You may have light switches and/or electrical outlets on the wall that protrude through your home's living spaces. They are easily air sealed with a bead of silicone caulk around the perimeter of the electrical box where it protrudes through the drywall. Shoot a dab of caulk around any holes in the electrical box where the wires enter and exit. Then smooth it out with your finger.

Second, focus your attention on the bottom of the wall. Fumes can seep in underneath the wall framing where the wood rests on the concrete or block foundation. Run a bead of silicone caulk along the bottom of the wall between the wood and the concrete. Smooth it out by running your finger along the wall. This forces the caulk into the crack so it can completely seal out the fumes. If your wall has a double plate or two 2x4s resting on the foundation, shoot another bead of caulk in between the 2x4s and smooth it out.

Last, air seal the wall cavities where the 2x4s touch the inside of your home's walls. Take a can of foam insulation and quickly run the tip around the perimeter of the wall cavity while squeezing the trigger. This is especially important in the bottom part of the wall because most of the fumes are heavier than air and will leak in.
