Should I Insulate My Garage Door?

A rendering of a home viewed through a magnifying glass illustrates the concept of analyzing whether to insulate a garage door.

If you invest in an insulated garage door, make sure the rest of the garage is adequately insulated.

Homeowners know that insulation keeps a house more comfortable. If your garage is connected to the rest of your home, insulating the garage door may reduce heating and cooling bills. However, the decision to insulate a garage door isn’t an open-and-shut case. There are special considerations when it comes to making a door more airtight.

Will Insulation Interfere With the Garage Door’s Function?

Garage doors typically get heavy use. They need to open and close smoothly. Insulation that works well when added to walls, such as spray foam or batting, isn’t ideal for garage doors. Retrofitting a garage door with insulation can cause the material to flake and pull apart from the door’s motion. Adding weight to a door may strain an automatic opener’s capabilities. Over time, the insulation will wear out and you’ll need to replace it.

Don’t Judge a Door By Its Thickness

A better choice than aftermarket add-ons is to install a door that is already insulated. A thick, heavy door isn’t necessarily more efficient at preventing heat loss. Polyurethane, often used in combination with steel, is thin and lightweight.

Insulation is rated by R-Value. The higher the R-Value number the more effective the insulation. Very cold or hot climates require a higher R-Value than milder climates. Insulated doors do more than save money on utility bills. Insulation dampens noise from the street, reduces the sound of opening and closing and makes the door stronger and more resistant to thieves.

Insulate the Rest of the Garage

An insulated garage door can only do so much. The floor, walls and ceiling of a garage may not be insulated. If you’re investing in an insulated garage door, you should also make sure the rest of the garage is protected. An insulated ceiling, particularly if there’s an upstairs room, will reduce energy loss. Check the walls, both interior and exterior, for insulation. Wherever there’s inadequate insulation, add more. The more you can reduce the temperature fluctuations in the garage, the better it will be for the adjoining spaces.

Not every home needs an insulated garage door. If your home’s temperature is comfortable, and you use your garage only for parking your car, you may not need more insulation. However, if you’re experiencing heat loss because of a drafty garage, we can help you out. Our experienced technicians will evaluate your garage and advise you concerning various insulated doors.
