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 />
