How To: Insulate garage doors with foam board insulation for a warmer winter

Insulate garage doors with foam board insulation for a warmer winter

When it comes to winter weather, the garage should not be neglected, especially if you have a room directly above it. Neglecting to properly insulate and seal your garage doors will create a constant rush of cold air inside, making the garage really cold, in turn making the floor upstairs really cold. This will drive up your gas or electric bill in no time during the winter months. But you can fight higher heating costs with some DIY ingenuity, and Dave Mars will show you how!

Your first line of defense for warming up your garage is weatherstripping. Adding weather seals along the top, sides and bottom will greatly reduce the rush of cold air coming inside. For instructions on how to add weatherstripping to your garage doors, check out this video on WonderHowTo.

The second line of defense against freezing garages is insulation. Strategically adding insulation to the panels on the inside of the garage door is a surefire way to keep your heating costs down in the wintertime. This video will show you the steps to properly insulate garage doors with foamcore.

For a warm garage, you need to add small insulation panels in the recesses of the garage door. Then, after all of the recesses are insulated, it's time to install insulation overtop all of them, to cover the whole horizontal panel.

Tools needed:
* Tape measure
* Utility knife
* Straight ruler
* Marker or pencil
* LIQUID NAILS adhesive (or similar product)
* Caulk gun
* Washer nails
* Insulation— your choice of:
— foam board with foil covering (foil board)
polystyrene panels
polyurethane foam
— Other insulation board
