Title: Thermalized Aluminum Window

Thermalized Aluminum Window
In addition to having double or triple insulated
glass, along with other performance options such
as Thermal E and tinting, a Thermalized window
offers another important feature. The window
frame and sash frames are insulated against heat
and cold conduction. This is done by separating
the outside metal parts from the inside with a
material such as polyurethane, greatly reducing
the amount of heat or cold transferred through
the frames. This feature is known as a thermal
break or thermal barrier.
How does a Thermalized window perform?
Thermalized windows are manufactured from
close-tolerance aluminum extrusions. All of our
thermal barrier aluminum frames are heat
strengthened by bringing the raw aluminum up to a
T5 temper to increase both strength and
rigidity. This allows us to build extremely
large windows without affecting performance like
most aluminum windows. They have lower air
leakage and higher resistance to heat transfer
than non thermal break windows. With double
glazing, they will stop 26 to 38 of the heat
lost through comparable wood windows made at
local millwork shops.
A thermalized aluminum window performance is
equal to or better than well-made wood windows.
Thermalized aluminum windows surpass strict
industry specifications. Air leakage with a 25
MPH wind blowing outside cannot exceed 0.375
cubic feet per minute (CFM) for every foot of
weather-stripped window perimeter. Our 700 Series
Double Hung allows only 0.06 CFM air infiltration
 one sixth of the industry standard! Old, worn
out windows often have rates of 1.5 or more, 25
times the air leakage of our best Thermalized
aluminum windows!
Do Thermalized windows prevent condensation?
No window is condensation-proof. Even walls will
sweat under high humidity. Windows do not cause
condensation they simply prevent moisture from
escaping and provide a surface that allows
condensation to be readily seen. If inside glass
and frame surfaces on a Thermalized window show
excessive moisture, you can be sure that moisture
is also present in your walls and ceiling.
What is the recommended interior humidity level?
The maximum recommended interior relative
humidity ranges from 15 at -20ºF to a maximum of
40 at 30º. Many homes have been built tighter
to conserve energy, leading to indoor humidity
above the recommended levels. The best way to
handle high indoor humidity is to vent the
moisture to the outside. Bathrooms, kitchens and
laundry areas should be vented with a fan, or by
opening windows slightly when the areas are in
use. If that does not help, a dehumidifier might
be necessary.
Special Shape Custom Windows As both the
manufacturer and installer, theres almost no
limit to what we can produce. Almost any shape is
possible, and we will custom make all of our high
performance windows based on your designs. In an
industry thats brought up middle men installers
who are overly attached to standard sizes and
obscene costs for special orders, buyers have to
beware which pieces of advice are best for the
customer, and which are best for the
seller. Of course, this also applies to
traditional shapes at larger than common sizes.
Many times, manufacturers are uncomfortable
shipping very large windows across state/country,
and installers therefore dont have enough
experience to want to work with them. Not the
case here, as our crews work side by side with
the very people who made the window to ensure its
handled and installed properly.
Bold new designs or timeless traditional. We can
help you realize your dreams. Our professional
staff is ready to help you. These photos are a
small sampling of actual jobs weve done in the
past. We look forward to adding yours to our
proud portfolio of beautiful work.
