What qualifies as an energy efficient replacement window?

Considering new replacement windows for your home can be quite exhausting, as a homeowner, especially if you don’t know exactly where to start. Today, everyone is looking for value, quality and energy efficiency-and every window claims to be the best.

Replacement windows are made from vinyl, fiberglass and wood; adding style, curb appeal, natural sun light, and energy efficiency to your home. In addition, some windows even cut down on excess noise. In comparison, old windows tend to allow air to escape in and out of your home, robbing your home of its heating and cooling efforts, adding to your home’s monthly heating and cooling costs. Over time, these old windows really take a toll on your wallet.

New energy efficient replacement windows can and will save you money. In fact, most will end up paying for themselves through reducing your heating and cooling costs, and providing Uncle Sam’s tax credit for qualifying windows.


Replacement windows are designed to easily fit into the existing window frames. They’re made from vinyl, fiberglass and wood, and can be custom-made to fit when requested by the homeowner. Upgrade your home’s curb appeal by choosing the most complementary option from the manufacturers’ large variety of styles, colors and sizes.

Energy Efficiency

For a limited time, Uncle Sam is offering a substantial tax credit for installing new energy efficient replacement windows. There are certain qualifications the windows must meet to be considered; so it is best to contact the manufacturer to determine a window’s eligibility.

Several reports claim that new energy efficient replacement windows can reduce your monthly electric bill by 10% in the winter time and 25% in the summer time. Doesn’t that sound perfect?


Are you an experienced do-it-yourselfer? Well, keep your eye out for those manufacturers with the pre-made replacement windows. Some carry large varieties making shopping for the right replacement a breeze.

Once you take the correct measurements, an experienced do-it-yourselfer can purchase ready-to-hang replacements and easily install the windows themselves. For the best possible fit, be sure to measure the existing windows in your home from jamb to jamb, vertically and horizontally. Always measure three locations on the existing windows. Measure the top, bottom and middle. Always, select the smallest measurement for each existing window, in order to get the correct width and height for your new replacement windows.


Replacement windows come in a large variety of styles all depending upon how each window opens. They come in double hung, single hung, or encasement. Double and single hung windows are designed to tilt inward for easy cleaning and maintenance for the homeowner. Encasement windows swivel and open vertically from the center.

Customers can also choose from a large selection of window grilles, which are optional in window replacement. The grilles can be built between the panes.  Bay windows are also another available option.


Before installing replacement windows in your home, be sure to check the existing wooden window frames and sills for decay or rot. Don’t install new, costly replacement windows in your home if rotting or decay exists.
If this is the case, make any necessary repairs prior to installing new replacement windows. In doing so, you’re preparing the right environment for your new windows, instead of setting them up for failure.


For some, replacing windows is a great do-it-yourself project that could save on some of the installation fees. But, not everyone has the experience or confidence to complete this kind of project. If you want to take a shot at doing this on your own, there are several replacement window manufacturers that offer videos and step by step guides to assist you along the way. But if you have doubts, questions or concerns, it’s best to consult with a professional.


There are plenty of manufacturer representatives that are ready to measure your home’s existing windows and plan for the replacements to be a snug, tight fit. A professional will evaluate your existing windows, give you an estimate and answer any questions or concerns you may have.
