New
home windows and operating styles
Select the best
replacement energy efficient windows
There are several types of new home windows to
choose from. And the overall window energy efficiency can
depend on the operating style itself.
Ensure that you select the best energy efficient
windows for your home by comparing and contrasting the
difference between
sliding and hinged windows, sometimes called projected windows.
 Single and Double
hung
These windows slide open and shut. In double hung
windows both top and bottom parts open or slide vertically.
These operating types more often than not have
high air
leakage rates therefore compromising overall window
energy efficiency.
Horizontal Sliders
Both single slider and double slider units are essentially single or
double hung windows that open and seal horizontally. Sliding models in
generally have the same air leakage rates as single hung and double
hung windows.
Casement
One benefit of this operating type is that the
entire window can be opened to maximize warm climate breezes, unlike
vertical and horizontal sliders.
More importantly hinged units usually have lower
air leakage rates making, them some of the best replacement and new
home windows on the market.
Awning
Awnings
just like casements are hinged, but there hinged along the top
of
the frame and the window opens outward. Since they are hinged, they
also have relatively good air leakage rates just like casements.
Hopper
Hoppers are hinged at the bottom part of the frame and open inward.
Just like all hinged units the entire window can be opened. Low air
leakage rates also make hoppers some of the best energy efficient
windows available.
