Here at Home Windows Installed in Indianapolis and approved by The Department of Energy estimates that over 20% of heat loss or gain may be due to radiation which comes through faulty or non-insulated windows in Indianapolis. It is not uncommon for well-built homes in Indianapolis to have windows that measure a high (U) Factor (which is undesirable). To support this point, here is a direct quote from a Department of Energy publication:

“Windows can be one of your home’s most attractive features. Windows

provide views, day lighting, ventilation and solar heating in the winter.

Unfortunately, they can also account for 10% to 25% of your heating

bill. During the summer, sunny windows make your air conditioner work two

to three times harder.

The (R) Factor – the resistance to heat flow or the degree to which a material resists heat transfer. The higher the R-Value, the better the insulating performance.

The (SHGC) Factor – It refers to the fraction of solar radiation passing through the window as heat compared to the amount of solar radiation striking the window.
 

The (U) Factor – the measurement of how much heat is transferred through a window. A lower U Factor represents better insulation and less heat flow.

With today’s high performance window technology at Home Windows Installed in Indianapolis, any homeowner can have a proven solution to resisting the sun’s heat in the summer and welcoming the same heat in the winter. Here in Indianapolis our windows are energy efficient windows that are engineered to accommodate almost any budget while providing the highest levels of year-round comfort and energy savings - making them well-suited for virtually any climate or season in Indianapolis.

Home Windows Installed of Indianapolis carries High Performance windows that are “Green”, a phrase which indicates that the product meets all of the standards for valuing and protecting our ecology. They are green, because they use technology that will help lower your energy use in your home. This in turn reduces air pollution such as CO2 thereby making a greener environment for everyone in Indianapolis and surrounding cities.

The fact is, for most of us in Indianapolis, our home is our largest single investment. Replacing windows in Indianapolis is wise, you either protect your investment, or it depreciates and makes the home less valuable when you resell it. The added benefit is that while you’re living in the house, the cost of maintaining your windows is reduced dramatically.

Remodeling Magazine conducts an annual unbiased survey which is based on a study of how this investment may also affect the ultimate resale of a home in Indianapolis and Central Indiana. The data is segmented by geography and issues of weather, etc. The majority of the Indianapolis homeowners interviewed were in complete agreement with the survey as it reflected on their original investment and the ultimate return.

Today, the Home Windows Installed Indianapolis replacement window is manufactured in Evansville, IN with options for different seasons and geographic needs. The industry has grown in sophistication and has developed methods by which to examine the efficiency of these Indianapolis window products. As an example, the National Fenestration Rating Council (NFRC) (http://www.nfrc.org) developed a recognized rating system based on studies surrounding the product performance of these windows.

The NFRC Rating System enables purchasers of replacement windows to determine the energy efficient properties of the windows they are contemplating. The NFRC label, together with its rating format, appears on all Indianapolis replacement windows which are part of the Energy Star program.

The Department of Energy together with the Environmental Protection Agency have developed an outstanding program that is internationally recognized called Energy Star (http://www.energystar.gov). Products bearing this label are required to meet special criteria and standards. The Energy Star program takes into consideration the various climates such as Indianapolis (for designated climate zones) and conditions that might affect the performance of the window.

Our Indianapolis replacement window of today takes into consideration the many and variable conditions under which the window will have to operate here in Indianapolis. We have already discussed (R) and (U) Factors as well the solar heat gain coefficient. Remember, this is the fraction of solar radiation passing through the window as heat compared to the amount of solar radiation striking the window. Depending upon where you live and under what condition the window will operate, it is important to ask about this when considering the windows you will have replaced in your home here in Indianapolis.

When it comes to understanding the glass or glazing (glazing is the layers of glass in a window) in your window, here is a nontechnical explanation on what to look for. First, understand that only about half of the sun’s energy is in a form that is visible to the human eye. The rest only contributes heat to the inside of your home. So you want a glazing that maximizes the amount of light entering your home while still minimizing energy use. And here is the simple rule that goes with this maxim: Double-pane windows with Low-E Coating and argon gas (or similar) offer better insulation qualities and reduce cooling loads in Indianapolis.

The further south you are located, the more shading you want from your windows. The farther north you are, the less shading you need.  Having a manufacturer who combines the right amount of Low-E coating, the right gas and the proper coefficient for shading will make all the difference in Indianapolis. We make sure to develope windows in Indianapolis that surrpase any conditions that may come from season to season.

First be sure you examine the balancing system on a double hung window. This is the mechanism that permits you to move the window up and down easily. A well-designed and well made window always incorporates a well-balanced system.

The Department of Energy includes these tips on their Energy Savers website (http://www.energysavers.gov).

• When you’re shopping for new windows in Indianapolis, look for the National Fenestration Rating Council label; it means the window’s performance is certified.

• Remember, the lower the U-value, the better the insulation. In colder climates, a

U value of 0.30 or below is recommended. (This will help you qualify for the tax credit that ends December 31, 2010.) These windows have at least double glazing and a low-e coating.

• Similarly when summertime heat gain is the main concern, look for windows with double glazing and spectrally selective coatings that reduce heat gain. 

• Select windows with air leakage ratings of 0.2 cubic feet per minute or less.

• In temperate climates with both heating and cooling seasons, select windows

with both low U-values and low solar heat gain co-efficiency (SHGC) to maximize energy benefits.
