Energy Efficiency Is The Major Goal Of Replacement Windows
 With the high cost of utility bills these days, and the
environmentalists lobbying for ways to save energy, the replacement window
industry has stepped up to the plate and produced many ways to please everybody
involved. Energy-efficient windows
are becoming the norm today and the methods of accomplishing this are quite
interesting.
If you stand by your window, it's easy to understand why changes are being
sought. In the summer, it's hot; in the winter, it's cold. So there's a drive to
build a wall between you and the outdoors ' a wall you can still see through.
And that's what technology has created. They've found a way to keep your house
comfortable, no matter what the season or climate.
You want your home to be warm in the winter and cool in the summer. If your
windows are there just to allow you to see outside, then they're doing their
job. But if you want them to be instrumental in keeping your house at a constant
comfortable temperature, then you need more. You need the new technology of
replacement windows.
One of the first methods of insulating your windows was to double them ' that
is, put two panes of glass in the window frame, with an airspace between the
two. The idea behind this is that the air between the panes will keep the
outside window at the outside temperature, and the inside window at the inside
temperature, and 'ne'er the twain shall meet'. This worked fine, but not as well
as people wanted.
The next innovation was to cover the window with a clear coating that would
improve heat loss without decreasing light. That improvement came in the form of
low-emissivity (Low-E) glass. It improved heat loss by 40%-70%. But people
wanted still more.
So heat-absorbing glass was developed. This glass absorbs up to 45% of sunlight,
keeping indoors cooler. However, some heat was still getting through. So on to
the next development ' reflective glass. Reflective glass is coated with a film
that reflects sunlight instead of absorbing it. So now the heat stays out, or
in, depending on what time of year it is, and on what you need to make you
comfortable..
