Garage Door

Lower Energy Costs Year-Round with an Insulated Garage Door


A leaky, uninsulated 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 an unheated garage 10 to 20 degrees warmer on a cold winter day. “That can have a significant impact on the comfort of family rooms or bedrooms located above or next to the garage,” adds Westerfield.

Homeowners who purchase an energy efficient garage door by December 31, 2010 will not only save on their heating and cooling bills, they may qualify for up to $1,500 in federal tax credits, thanks to the stimulus legislation. 
The tax credit is equal to the sum of 30 percent of all qualified energy saving improvements, which includes garage doors, installed in an existing home from January 1, 2009 to December 31, 2010.

For example, if two new garage doors cost $2,000, the applicable homeowner tax credit is $600. The credit applies to the product only (not labor) and the maximum credit for all of the improvements combined is $1,500. 
A tax credit is more valuable than an equivalent tax deduction because it reduces tax dollar-for-dollar, while a deduction only decreases the amount of income that is taxed.
Garage doors must meet the following criteria to qualify:

– The door must be an insulated residential garage door placed in service from January 1, 2009 through December 31, 2010. 

–  The door must have a U-factor equal to or less than 0.30, and there must be a means to control air filtration at the door perimeter. 

–  The door must be expected to remain in service for at least five years.

–  The garage must be an insulated space and part of the taxpayer’s principal U.S. residence.

Professional garage door dealers and retailers should provide a manufacturer’s certification statement for all qualified insulated garage doors along with a breakdown of the cost of the door(s) and the cost of labor at the time of installation. Homeowners do not need to submit a copy with their tax return, but should keep a copy for their records.

Helpful Tips
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: 

– 2” thick three-layer ”sandwich” construction – environmentally safe, CFC-free insulation layered 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.

– Energy tax credit eligible – available for garage doors with a minimum U-factor of 0.30 installed on a homeowner’s primary residence.

– Insulation type – There are two different types of insulation used in garage doors: expanded polystyrene and polyurethane. Doors constructed from either kind qualify for the energy tax credit, and both are strong and durable.

– Design – Get the most out of your garage door upgrade. Choose a model that complements your home’s architectural style.
