How To Make Your Garage Door More Efficient

If you have a heated garage, you don't want all of that expensive heat to just leak out through the door. While replacing your current garage door with a new, highly efficient one is certainly an option, doing so can be expensive. Another option is to take a few steps to make your current garage door more efficient. Here's a look.

Repair any cracks or holes with spray foam insulation.

If there are any cracks or little holes in your garage door, air can easily leak out through them. An easy way to fill them is to purchase a container of spray foam insulation at your local hardware store. Apply a tiny spray of the insulation to the inside of the door along each crack or hole. The insulation will expand to fill the crack, stopping air flow and also acting as a heat barrier.

Note: If you have a layer of insulation on the back of your garage door already, you will need to remove it before applying the spray foam, and then put it back into place.

Apply a layer of fiberglass insulation.

If your garage door does not have a layer of insulation along its back, then adding one is a great step towards reducing heat loss. You can find sheets of insulation that are sticky on one side. You just peel off the backing, and stick them to the garage door. Usually, these sheets are pretty small so that you can piece them together easily. Make sure you pre-measure your door so that you know how many sheets to buy and how to best lay them out on the garage door to avoid leaving extra space.

Repair broken or loose gaskets.

Your garage door should have a rubber or plastic gasket along the bottom edge so that when you close it, there is no air gap between the door and the ground. These gaskets have a habit of becoming worn out over time. If yours has any cracks or holes in it, then your warm air will be escaping right through them. Replacing the gasket is your best option. 

You can purchase a new gasket at most home improvement stores. Typically, you'll just measure your garage door's length and cut the gasket to fit. Unscrew the screws that are holding the existing gasket in place, and then pull the old gasket out of the slot. Use your fingers to maneuver the new gasket into place. (Most just push into a ridge at the bottom of the door.) Then, put the screws back into the door. You can then apply a thin strip of adhesive between the door and the gasket to hold it in place more effectively. 

Re-caulk any windows or panels.

Stand to the outside of your garage door, and put gentle pressure on each of the windows and various panels. If any of them move, then they are too loose and are probably allowing air to flow through them. Luckily, this is a problem you can easily remedy with some caulk.

Make sure you choose a heavy-duty silicone caulk designed for outdoor use. Put it in a caulk gun, and cut the tip of the caulk tube so that only a very, very thin bead of caulk comes out. Practice using the caulk gun on a disposable piece of cardboard if you don't have a lot of caulking experience. When you feel comfortable doing so, apply a thin bead of caulk between the loose window and the garage door. Use your finger or a tiny spatula to smooth out the bead of caulk. Let the caulk dry, and enjoy your more tightly sealed garage.

With the steps above implemented, a lot less heat will escape through your garage door. For more information, visit websites like https://planooverhead.com/.
