Lower Your Energy Costs with an Insulated Garage Door

A leaky, non-insulated garage door may not be an obvious culprit in rising monthly utility bills, but it’s worth a second look if you have an attached garage. Replacing an older garage door with a new, energy-efficient model can reduce energy loss through the garage by up to 71%, according to a comparison study conducted by engineers at Clopay Building Products, the nation’s leading manufacturer of residential garage doors.

“Since attached garages typically share one or two common walls with the house, any hot or cold that travels through a door will ultimately affect the adjacent living areas,” says Mark Westerfield P.E., Director of Product Development for Clopay. “An insulated garage door can help stabilize temperatures in the garage to reduce heat losses or gains.”

Depending on the specifics of the home, a well-insulated door can help keep a garage 10° to 20° cooler on hot Florida days.

“That can have a significant impact on the comfort of family rooms or bedrooms located above or next to the garage,” adds Westerfield.

Things to Know When Considering an Insulated Garage Door

More than 40 percent of the current housing stock was built prior to the era of energy efficiency.* If your garage door is a holdover from the dark ages, here are some things to look for when making an upgrade:

  • Types of Insulation: there are two types of insulation used in garage doors; expanded polystyrene and polyurethane. Doors constructed from either kind can qualify for the energy tax credit, and both provide extra strength and durability to a garage door.polyurethane and polystyrene garage door construction
  • Energy Tax Credit Eligible: available for garage doors with a minimum U-factor of 0.30 installed on a homeowner’s primary residence.
  • Layered “Sandwich” Construction: Clopay garage doors, can come with 1, 2 or 3 layers of insulation, with 3 layers providing the best energy efficiency for homeowners.  These layers are sandwiched between two sheets of heavy-duty galvanized steel.
  • R-value or U-factor: these are measurements of the thermal efficiency of a door’s insulation. The higher the R-value, or the lower the U-factor, the more energy-efficient the insulation is.
  • Custom Design Options: insulated garage doors come in a number of different collections and series that offer design customization to best match your home’s exterior.
