Energy Star Windows and Doors
Want more from your windows? Ask for ENERGY STAR.
qualified windows, doors, and skylights save you energy and money,
increase the comfort of your home, and protect your valuable possessions
from sun damage. They are also better for the environment because
lowering your energy use means less air pollution from power plants.
Save money and energy.
Replacing single-paned windows with ENERGY STAR qualified windows or
choosing ENERGY STAR overthe typical clear-glass double-paned
alternative can save a significant amount of money on your energy bill.
Say goodbye to winter drafts and sweating in the summer sun.
Thanks to a host of new technologies, ENERGY STAR qualified windows,
doors, and skylights keep your home cooler in the summer and warmer in
the winter, making you more comfortable.
ENERGY STAR qualified windows, doors, and skylights do more than just
lower energy bills – they deliver more comfort, create less
condensation, and protect your valuables from sun damage better than
conventional clear-glass double-paned alternatives. By lowering your
energy use, these windows are also better for the environment: The less
energy you use, the less air pollution power plants produce.
Protection from Winter Chills
On cold winter nights, do you avoid seats near the window? Do drafts
chase you from room to room? When the mercury drops to single digits,
even tightly sealed traditional double-paned windows can still make you
shiver. The cold, inside surface of an inefficient window pulls heat
away from your body, so you can feel chilly in a sweater with the
thermostat at 70 degrees. With ENERGY STAR qualified windows, the inside
window glass stays warmer, so you can relax in your window seat even
when the temperature outside dips well below freezing.
Shielding from Summer Heat
In summer, do your windows seem like giant heat lamps? Are you denied
your view because you have to keep your blinds perpetually closed? A
typical double-paned, clear-glass window allows approximately 75 percent
of the sun’s heat into your home, almost as much as a single-paned
window. Windows qualified for ENERGY STAR in the North/Central,
South/Central and Southern ENERGY STAR Climate Zones transmit only 30 to
55 percent of the sun’s heat, usually without noticeably reducing the
visible light. You get the light but a lot less heat. So you can relax
and enjoy the view in summer too.
Protection for Valuable Interiors
Your favorite photograph, half a loveseat, your Persian rug, even
your flooring can fade or discolor after repeated exposure to direct
sunlight. An ENERGY STAR qualified window with Low or Moderate Solar
Gain Low-E coatings--the same coatings that keep out the summer
heat--can reduce fading by up to 75 percent. These coatings are like
sunscreen for your house, blocking damaging ultraviolet light without
noticeably reducing visible light.
When you open your curtains on winter mornings is the ice or fog you
see on the inside or the outside? If an inefficient window or window
frame gets too cold, water can condense or even freeze on the interior
surface and then pool on the sill. Over time, chronic condensation can
damage sills, cause paint to crack, and encourage the growth of mold.
Advanced frame, glass coating, spacer and other technologies enable
ENERGY STAR qualified windows to keep the inner surface of the glass and
frame warmer, reducing the potential for condensation and ensuring a
clearer view on winter mornings.
Don’t Forget the Last “Window”
In most homes the air leaks and unsealed gaps under doors and around
pipes allow as much heat in or out as a wide-open window. Make your home
more comfortable and efficient with Home Sealing.
Protect your home’s interior
Many ENERGY STAR qualified windows, doors, and skylights act like
sunscreen for your house, protecting your photographs, artwork,
furniture, carpets, and wood floors from sun damage.
Buy with confidence.
Every ENERGY STAR qualified window, door, and skylight is
independently certified to perform at levels that meet or exceed strict
energy efficiency guidelines set by the U.S. Department of Energy.
Ask for ENERGY STAR.
To purchase the most efficient window for your home, ask for products
that are ENERGY STAR qualified in your Climate Zone. To learn more, see
the window purchasing tips.
Confirm the ENERGY STAR Label
Before the new product is installed, check for the ENERGY STAR label
and make sure you have received the correct product.
Windows should display an official ENERGY STAR label (examples below)
or equivalent custom label, next to the NFRC label. There are a variety
of custom labels, but all should include the same elements as the
- The ENERGY STAR Certification Mark
- A map showing where the product is qualified
- A qualification statement
- Seal and insulate with Home Sealing. Sealing your home’s envelope
is one of the most cost-effective ways to lower your home’s energy
bills and improve your comfort.
What’s in a pane - or two?
All energy efficient windows have at least two panes, but not all
double-paned windows are energy efficient. Twenty years ago,
double-paned meant energy efficient; today, advanced technologies have
enabled the development of windows that are much more efficient than
traditional clear-glass double-paned windows. For maximum energy
savings, don’t count panes; count on ENERGY STAR.
Have Windows Properly Installed
Proper installation is critical for achieving full product
performance and avoiding water damage. Windows, doors and skylights
should be installed by trained installers according to manufacturer
instructions. Many manufacturer warranties are void if the product is
not installed according to instructions. When hiring a contractor,
interview candidates and ask for references. The Federal Trade
Commission recommends questions to ask potential contractors. (new

take proper precautions.
