What Makes a Window Energy Efficient?<br />

by Jennifer Evans<br />

Many factors determine a window’s<br />

energy efficiency. The first is Low-E<br />

(Emissivity). It’s a reflective coating on<br />

the glass that reflects heat. Low-E works<br />

to keep homes comfortable year-round.<br />

In the winter, heat is reflected into the<br />

room instead of leaking out into the environment.<br />

In the summer, the outside<br />

coating reflects UV rays out, so that it<br />

doesn’t penetrate the glass. Reflecting<br />

UV rays also reduces the ability for<br />

the sun to fade carpet, furniture, and<br />

upholstery.<br />

The next attribute for energy-efficiency<br />

is argon gas. It’s an irenic gas and<br />

fills the gap between the glass, raising<br />

the R-value of the window. R-value<br />

is a measurement of insulation. As an<br />

example, for insulating a wall, you<br />

would choose from R 13, R 15, or R<br />

<strong>19</strong>, depending on how thick your walls<br />

are. Argon adds some insulating feature<br />

as well.<br />

Obviously, a window is a big hole<br />

in your wall with glass in it, so the more<br />

insulating factor or R-value you can get,<br />

the more energy efficient it is. Thus, argon<br />

increases the R-value and keeps the<br />

heat in or out depending on the weather<br />

and temperatures outside.<br />

When replacement windows were<br />

first on the market, there was often a<br />

lot of condensation around the edges<br />

of the window. New technology and a<br />

better-made window have mostly eliminated<br />

this. It reduces the heat transfer,<br />

which in turn, cuts down on any condensation<br />

around the window.<br />

Another way windows are energy<br />

efficient is the use of interlocking meeting<br />

rails. It is a feature that locks the<br />

window tight and prevents air to pass<br />

through. When there are two sashes,<br />

there will be an interlocking meeting<br />

rail. Weatherstripping is another feature<br />

of new replacement windows that<br />

delivers the ultimate benefit. Weatherstripping<br />

should be placed where this is<br />

vinyl to vinyl contact in or other frame<br />

material such as wood, fiberglass, or aluminum.<br />

The weatherstripping prevents<br />

you from being able to see right outside.<br />

Weatherstripping helps decrease drafts,<br />

especially in colder or windy weather.<br />

As you can see, all these energy-efficient<br />

improvements for replacement<br />

windows help consumers reduce energy<br />

costs. Replacing old windows with<br />

ENERGYSTAR® certified windows,<br />

the U.S. government’s label for windows<br />

meeting certain thresholds lowers<br />

household energy bills by an average<br />

of 12% nationwide. Lower energy consumption<br />

also reduces greenhouse gas<br />

emissions from power plants and homes.<br />

If you are considering replacing<br />

your windows, be sure to ask about<br />

the energy-efficient characteristics of<br />

the window so that you make a sound<br />

investment.<br />
