FOR BETTER VIEWS AND COMFORT
Cut heating and
cooling losses with the best glass in the industry: Milgard
SunCoat™ Low-E all climate, all-season glass. It's the "clear"
glass choice for energy-efficient windows that give you
year-round comfort. You'll find it on all Milgard insulated
windows. Not only does it make our windows more energy
efficient, but it also protects your carpet and furniture from
fading. SunCoat Low-E blocks infrared light and reduces
ultraviolet light.
WHAT IS SUNCOAT™
LOW-E?
SunCoat Low-E is
a clear, low-emissivity coating applied to one side of the
glass in our dual-pane windows. This microscopically thin
coating filters the sun's energy in the summer and reduces
heat loss in the winter, making even energy bills look better.
Low-E has been a product usually recommended for cold
climates. Now with our introduction of SunCoat Low-E glass,
you can use this product everywhere, from the heat of Southern
Nevada desert to the cold of Chicago and Alaska winters.
You can get even
greater thermal performance with the addition of argon gas to
our standard, dual-pane, SunCoat Low-E insulating glass. In
fact, our vinyl and fiberglass insulated windows have even
been recognized by Energy Star® for their exceptional
energy-saving qualities in your home.

Benefits of
SunCoat™ Low-E |
|
|
| |
|
- SunCoat
Low-E allows most natural light to enter freely but
absorbs a significant portion of short-wave heat energy.
- In the
summer, long-wave heat energy radiating from objects is
reflected back outside, lowering cooling cost.
- In
winter, internal long wave heat energy is reflected back
inside, lowering heating cost.

ENERGY SAVINGS
Windows can
account for up to 30% of the annual energy consumed in a home.
In the summer, Milgard's SunCoat Low-E keeps your home cool
and comfortable by rejecting the sun's heat and damaging rays.
In the winter, SunCoat Low-E helps your home stay warm and
cozy by blocking heat loss to the cold weather outside.
Heating and Cooling Energy Savings*
(Percentage of dollars saved over ordinary glass. Savings by
market.)
* Total energy
costs (heating + cooling) comparing clear 2-pane glass to
SunCoat Low-E, for a house with 15% window-to-wall ratio
uniformly distributed on all four sides of the house. The
actual savings can vary due to thermostat settings, use of
drapes and blinds, and other lifestyle attributes.
MILGARD SUNCOAT
LOW-E VS. ORDINARY GLASS
Installed in
identical test homes in California's central valley, Milgard
SunCoat Low-E glass demonstrated a remarkable reduction in
energy use compared to ordinary clear glass.
The home
featuring Milgard vinyl windows and SunCoat Low-E glass
showed a 27% savings in summer cooling costs compared to the
home with ordinary clear glass. The average summer afternoon
demand for air conditioning in the SunCoat house was 30%
lower due to reduced solar heat gain. SunCoat also produced
significant savings on winter heating bills.
The test
houses were identical single-story, 1,850 square-foot,
3-bedroom production homes. They were located on the same
block with identical orientation and solar exposure. About
50% of the glass faced west.
From the
standpoint of building design, this test proved that
incorporating SunCoat enables the use of more windows and
more dramatic views, without compromising on comfort or
energy efficiency.
