Energy Star
Windows - Government Certified Energy Efficient Windows
Every Kensington Window system with Formula A glass or better is an Energy Star
qualified window in all areas of the United States.
ENERGY STAR® windows is a program designed to help consumers identify energy efficient windows,
doors and skylights. By choosing ENERGY STAR® window products you can cut down your heating
and cooling costs, and make your home more comfortable at the same time. ENERGY STAR®
labeled windows are twice as energy efficient as the average window produced just ten years ago.

| Kensington's Energy Star Windows |
ENERGY STAR® Windows is a partnership between the U.S. Department of Energy and manufacturers
of windows, doors and skylights. The program was introduced by Secretary of Energy Federico Peña
on March 6, 1998 in suburban Washington, DC.
Did you know...
- An average household spends over 40 percent of its annual energy budget on heating
and cooling costs. You could reduce those bills by up to 15 percent with ENERGY STAR® windows.
- If all residential windows in the U.S. were replaced with ENERGY STAR qualifying models, we'd save $7 billion in energy costs over the next 15 years as a result of the energy efficient windows.
- The reduction in carbon emissions would be the same as taking 336,000 cars off
the road, and the energy savings would be enough to light every home in the New York City metropolitan
area.
ENERGY STAR® windows are good for the environment because they reduce the amount of energy needed
to heat our homes. Most energy is produced by burning fossil fuels, which causes air pollution, smog
and global warming.
Kensington's energy efficient windows go even further to maintain your home comfort and reduce energy costs:

Foam-Filled Frame and Sash
In select Kensington window systems, the hollows inside the vinyl frame and sash (optional on the
Kingston) is filled with Kensington Natural Foam™. Natural Foam is a polyurethane filling much like
that found in a refrigerator. This foam improves the thermal performance of Kensington's vinyl frames to an
insulating factor of R-25*. This added insulation adds to the high performance levels achieved by every Kensington Window and makes them more energy efficient.
Heat Mirror® Glazing
Heat
Mirror glass is one of most revolutionary developments in window glazing. Heat Mirror is a polyester
film suspended in the air space between the two panes of insulating glass. It's hard to see with your eyes
but the performance is quite apparent. Depending on the glazing system chosen for your Kensington window,
you can achieve a center of glass R-value of 9.09**.
But
Heat Mirror glazing systems offer even more! The Heat Mirror film is coated with special materials
that block harmful UV rays. UV or Ultra Violet radiation is produced by sunlight and is responsible for
sun burn and melanoma. These rays can also damage interior fabrics, furniture, and draperies. Depending
on the glazing system chosen for your Kensington Window, you can block 99.5% of all harmful UV rays.

|
 |
| In the summer, Heat Mirror glazing works to reflect heat and harmful
UV radiation away from the home. |
In the winter, Heat Mirror glazing allows sunlight into the home
while retaining radiated heat inside the home. |
Heat Mirror glazing and Natural Foam filling are just two of the many features available on a Kensington Window.
These unique components combine with the weather seals and natural insulating qualities of vinyl to produce
the high performance / energy efficient windows found only from Kensington. See the World in a Better Light, buy Kensington.
* R-25 is the rating on the frame system alone. For window performance ratings, please refer to the performance
test summaries for each particular system, located in the product catalog of this website.
** This R-value rating is measured at the center of the insulated glass unit. For window performance ratings,
please refer to the performance test summaries for each particular system, located in the product catalog of
this website.
