Energy Star Window Replacement FAQs


What is an Energy Star Rating?

Energy Star is a voluntary labeling project sponsored by the US Department of Energy and the US Environmental Protection Agency to identify energy efficient products. By using Energy Star-rated products to remodel your home, you can reduce your energy bills, improve your comfort and protect the environment.

How do energy efficient windows compare with ordinary windows?

Ordinary traditional windows have a single pane of glass and allow heat to escape during cold weather and cold to escape during hot weather. This can skyrocket your fuel costs. Many ordinary windows also require ongoing and costly maintenance like painting and sealing.

Energy efficient replacement windows rated by Energy Star are made with double or triple paned glass. These extra panels of glass are much more energy efficient, particularly when they are custom fitted to assure a tight seal where little or no air can escape. Energy efficient Energy Star rated windows installed by MasterCraft are made of vinyl or aluminum on the exterior with choices for no-maintenance vinyl or wood that can be painted or stained on the interior.

MasterCraft installs beautiful, well constructed, high performance Energy Star windows and doors by Thermal Industries. These windows offer a tremendous value, exceeding the quality and manufacturer warranty offered by high-priced popular brands.

What criteria is used by Energy Star to rate window and door performance?

Inferior Glass Spacer
There are two measures of energy efficiency for windows and doors. These include U-Factor and Solar Heat Gain Coefficient.

U-Factor, the first energy performance rating, measures heat transfer through a window and indicates you how well the window insulates.Lower U-factors are associated with better insulating functions which are particularly important during winter months. A low overall U-factor in cold weather means there will be less heat loss through the window and less energy required for heating that living space.

Solar Heat Gain Coefficient, the second performance rating, measures how much solar heat is admitted into your home through the window.An important measurement during summer months, the SHGC represents the performance of a window for blocking heat caused by sunlight. A lower SHGC means that the window is more effective in blocking heat through solar radiation. This keeps a home cooler in warm weather and saves on air conditioning costs.

How do Low-E glass, Argon gas and Krypton gas make windows energy efficient?

Low-E glass is normal-looking glass with a coating that provides better insulation and blocks certain types of light. Argon gas and Krypton gas are good insulators that can be used to fill the space between panes of glass in thermal replacement windows. These are components that produce a good Energy Star rating. In the Boston area and other cold climates, all replacement windows should contain Low-E glass and either Argon or Krypton gas. Although the initial cost is higher, the homeowner will recover the cost with future savings in heating and cooling the property.

Why is window replacement with Energy Star products a good investment?

Energy Star rated replacement windows add greatly to the beauty and value of your home. Not all Energy Star rated windows offer the same energy saving value. Windows rated by Energy Star that meet federal guidelines for tax savings are associated with a 7 – 15% reduction in energy costs. Approximately 40% of your heating and cooling bill is related to air leaking around windows and doors. Because replacement windows are two to four times more efficient than ordinary replacement windows, you can expect a significant savings in your heating and cooling costs. The money you save on fuel bills can more than pay for your replacement windows in a very short time.

The National Fenestration Rating Council, or NFRC is the organization that independently certifies window and door products to meet or exceed strict energy efficiency guidelines set by the U.S. Dept. of Energy. The NFRC label helps to measure and compare the energy performance of different window brands.

Factors that enhance the energy performance of a window or door include:

A Low-E coating within two or more panes of glass that blocks UV rays and reduces solar heat.
Spacers within panes of glass such as foam. Without acting as a conductor, warm edge spacers keep glass separated while helping to prevent heat loss and reduce condensation.
Argon or krypton gas between glass panes that improves insulation without toxicity, odor or color.

Energy savings, maintenance savings, aesthetic appeal and increase in property value make Energy Star replacement windows an affordable investment that is well worth doing. Many homeowners use home equity lines of credit to pay for window replacement, allowing them the convenience of monthly payments and the advantage of tax savings while enjoying years of comfort and enjoyment from beautiful, energy-efficient windows.

How can you determine the quality of an Energy Star rated window?

Windows are rated based on the NFRC rating system. The lower the rating number, the better the quality of the window. Windows with a low NFRC rating are better built and incorporate more energy saving features. Every manufacturer must display their NFRC ratings sticker on their windows. MasterCraft custom warm replacement windows have some of the highest ratings available.

Why should I know about bargain priced replacement windows?

Although you may find some attractive pricing on replacement windows at your local home center store, you may be compromising quality and energy savings.

There are three reasons why these bargain priced replacement windows are not a good investment:
  • Most are not well-built and will need to be replaced much sooner.
  • It is difficult to get a professional to install replacement windows purchased from a home center.
  • You want the replacement window to be exactly the right size for your window opening, otherwise it will be a very drafty, smaller-view window. A short on all four sides will make for a VERY drafty window! Failure to install windows to plumb and square standards with appropriate installation is very likely to reduce or eliminate all the energy cost savings value.

Are Energy Star replacement windows maintenance free?

No replacement windows are completely maintenance-free, but Energy Star replacement windows installed by MasterCraft are the next best thing. Replacement windows can be made of wood, vinyl or a wood and vinyl combination. Vinyl replacement windows require the least maintenance with no painting required inside or out.
