Help Save Energy and the Environment
Upgrade
Your Windows with our ENERGY
STAR® Qualified SolarZone™ Insulated Glass Package..
ComfortWorld Windows are already
designed for superior thermal performance. By choosing our SolarZone™
Insulated Glass Package, featuring PPG s Low-E Glass and Intercept™
Warm Edge Spacer System, you can help reduce your energy costs even
more, while helping cut consumption of the fossil fuels that pollute
our environment.
 What Makes
the SolarZone™ Insulated Glass Package So Effective?
Since 80% of a window is glass,
substantial heating cooling savings come from improved glass
performance. Our combination of
UV-filtering Low-E Glass, insulating argon gas and the Intercept™
Warm Edge Spacer System, creates significant energy efficiency.
Together they can cut the damaging effects of the sun, which can
lead to the fading of carpets, curtains and furniture by an
additional 78% over clear insulated glass units.
In winter, a warmer glass temperature is
maintained, increasing the R-value by an additional 104%.
In summer, a 48% reduction in solar heat
gain helps cut air conditioning costs
The result: your monthly utility bills
will reflect savings year round - and that should help make you even
more comfortable.
The
Benefits of the Intercept™ "Warm-Edge" Spacer System
The Intercept spacer system features a
unique, one-piece metal alloy, U-channel design that creates an
effective thermal barrier to help reduce conducted heat loss through
the window. Its sealed, one-piece design makes Intercept spacers
stronger and better at retaining insulating gas than many
conventional designs. Comfortable Rooms Start With the Intercept Spacers
Intercept spacers are so energy
efficient that they keep the edges of the window glass warmer, so
your home feels more comfortable in the winter. As you can see
below, the temperature difference between the edge of an insulating
glass unit with an ordinary spacer, and one with an Intercept spacer
system can be dramatic.
 Intercept I.G. units feature '"Warm-Edge" technology that reduces
condensation problems around the window perimeter. Compare the
Intercept insulating glass window "above left" with a conventional
insulating glass window "above right". Both windows have Low-E glass
and argon gas infill. The difference is the Intercept "Warm-Edge"
Spacer.
 The Intercept™ Spacer
Helps your Windows Last Longer Under normal weather conditions, LG. units expand and contract with
temperature changes. In conventional insulating glass units, the
sealant (the material that holds the unit together) takes the stress
of the flexing. This can cause seal failure and insulating gas loss.
In an Intercept I.G. unit, the spacer flexes instead of the sealant,
so it resists spacer movement and premature sealant failure.

The Solarban® 60 Low-E Glass - Making
the Difference The
Intercept Spacer System is just one way of increasing your window's
performance. Solarban® 60 Low-E glass, also from PPG is an excellent
option for increasing your home's comfort and energy savings year
round. Solarban® 60 Low-E glass is created by applying a
microscopic, undetectable metallic coating to the second surface of
an insulated glass unit. This coating helps to block out solar
energy in the summer while retaining furnace heat and allowing warm
short wave solar rays in the winter.
The therrnagraphs below clearly show the effect that Low-E glass
has when contained in an insulated glass unit. The window on the
left is a dear insulated glass unit. The heat transrnittance,
indicated by the green, yellow and orange colors from the heat
scale, is far more apparent than that of the window containing the
Solarban® 60 Low-E insulated glass unit.

Measuring Heat Loss Through U-Values For all window
products, the National Fenestration Rating Council (NFRC) has
created the NFRC-100, which is the standard test for heat loss
through a fenestration, or window product. Once the testing
procedure is completed, a U-Value rating is applied to the window
product. The lower the U-Value, the better the product is at
resisting heat loss. This chart easily illustrates why a window made
with Solarban6 60 Low-E glass will thermally outperform windows with
any of the lesser glass products.

Energy Efficiency, It All Adds Up Simply put, there are
many options available for improving the performance of a window. By
adding Low-E glass to a standard insulating glass unit, you can
improve the energy performance of your window year round by 24%.
Additionally, by adding argon gas filling to the window, which is a
better insulator than normal air, you can increase the efficiency by
another 6%. And finally, by adding the Intercept™ Warm Edge Spacer
System, you can add yet another 5% to the overall efficiency of your
window. So, wouldn't you agree that when you add all of these
together, by choosing ComfortWorld Windows with the SolarZone™
Insulated Glass Package, you have chosen the most energy efficient
window product on the market today?
