Windows & Energy Efficiency
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.
