Aluminum Windows: Are
They Your Best Option?
With
winter coming and predictions of soaring energy prices, now is the
perfect time to replace those drafty windows with the new energy
efficient replacement windows or to make sure your really provide the protection you need.
Aluminum windows—that
is windows actually made from aluminum are commonly used in commercial
buildings but are less common on residential buildings. That's because
the metal is a good transfer of heat—or cold, resulting in a loss
of heat during the winter and an influx of heat during the summer.
However, those who build structures with large windows need the
strength of the metal, so they give up a bit of efficiency for the
strength.
Aluminum replacement
windows are windows that replace those that are actually made from
aluminum. The major choices are wood, vinyl, and composite—such
as fiberglass. Wood retains its popularity but needs more maintenance
than vinyl or composite. To compensate, manufacturers cover the
exterior of the wood with a layer of aluminum, thus having aluminum
on the outside but the attractive wood finish for the inside.
Although they are less
common than other types of windows for residential use, many homes
do have aluminum windows, and because of their durability and low
maintenance, some homeowners use them to replace worn and damaged
windows in older buildings. They have some advantages over other
types of windows in that they are lightweight, easy to install and
will usually last for 20 years or more. Additionally, they are wind-resistant,
very inexpensive, and can be shaped into any kind of window you
desire. They can also be purchased with just a primer, allowing
you to paint them in any color you wish.
Aluminum windows do tend
to sweat in the winter—which can lead to mold, and in areas near
the ocean where the home will be exposed to salt, the paint can
deteriorate.
Storm
Windows
Storm windows are removable windows that you install only during
winter months. If you only have single pane windows, the storm window
will not keep your home noticeably warmer, but will improve energy
efficiency by limiting the movement
of air through the existing windows.
Storm windows are available
for most types of windows and range from inexpensive, single season
use, plastic sheets to triple track glass units designed to be used
for years. While the windows can be exterior or interior, the interior
ones are easier to install and last longer because they are not
exposed to the elements. The glazing itself can be plexi or glass.
The glass panes are more durable, although they are also easier
to break and heavier to handle. Plexi-glass scratches easily and
will sometimes turn yellow with age. However, it is also cheaper
than glass.
The best framing material
for storm windows is vinyl. Wood frames are bulky and difficult
to store as well as being less durable. Aluminum frames are inexpensive
but will partially defeat the purpose of the storm window due to
the conductive characteristics of the metal. Vinyl with plexi-glass
or plastic glazing will usually give the most satisfactory, long
term winter protection.
