What
makes a window or door energy efficient?
Numerous
factors, including how the frame and sashes are engineered and
built, the type of glass used (single-, double- or triple-pane), the
weatherstripping, the type of low-emissivity coating on the glass
and the presence of argon or krypton gas. (Back

What
is a U-value?
U-value
(or U-factor) is the measure of the window's ability to conduct heat—in
other words, the amount of heat transmitted through the window. The
lower a window's U-value, the better the window is at insulating
your home.

What
is Low-E and, how important is it to have it on your windows or
doors?
Low-E
stands for low emissivity and is a fairly new advancement in glass
technology. Basically, it's a microscopic, metallic coating—applied
to a surface of glass—that reflects and re-radiates heat energy
either into or out of a home depending on climate conditions. Using
Low- E is an excellent way to increase the energy efficiency of a
window. (Back

Does
argon or krypton gas between glass panes really make a difference in
energy efficiency?
For
air to insulate well, it needs to be as still as possible because
moving air carries energy. Both argon and krypton are heavier than
air—so they're less prone to convection or thermal movement. The
bottom line is that heavier-than-air gases offer a higher level of
insulation. Both argon and krypton are found naturally in the air
you breathe and are completely harmless. (Back

Is
there a way to improve the energy efficiency of existing (prime)
windows that are still in good condition but have just a single pane
of glass?
High-quality,
custom-built storm windows represent a practical way to improve the
efficiency of existing windows that are in good condition. Be sure
to choose only high-quality, custom-built storm products for your
existing windows to ensure the tightest possible fit and to seal out
the elements. (Back to FAQ)
