Warmer in the Winter... Cooler in the Summer...

Quieter all year around.

Most homeowners can cut energy costs as much as 15 percent by replacing leaky, inefficient windows with modern energy-efficient windows; if you have a great number of windows, if your home is more exposed (hillside, fewer trees), if you are in a location with a colder or hotter weather pattern, the greater your heating or cooling costs = the greater potential savings on energy costs. Components of an energy-efficient window include:

  1. Double-paned, insulated glass (standard in all of our windows)

  2. Airtight frames (standard in all of our windows)

  3. Fiberglass frames with multiple chambers

  4. Proper installation (we customize our installation approach to match your home’s age, construction style and finishes to ensure a perfect fit)

  5. Heat-resistant (Low-E) glass: an affordable additional option that deflects heat to its source (read more below)

  6. Argon gas between the window panes: another affordable additional option involving a non-toxic, odorless gas that boosts insulation and soundproofing

  7. ENERGY STAR® rating: the majority of our windows meet this qualification

What Does Low-E Glass Do?

The sun’s energy has 3 ranges of wavelengths: 1) visible light; 2) ultraviolet light, which you can’t see; and 3) infrared light, which you feel as heat.

Low-E glass has a special microscopic coating that prevents ultraviolet light, and reduces infrared light, while still allowing bright visible light to pass through. This helps keep the summer’s heat out and the winter’s heat in.

Low-E also blocks a majority of the ultraviolet light that can fade rugs, curtains, fabrics and floors, helping to protect your investment for years to come. Ultraviolet light is the number one cause of furniture and fabric fading and discoloration.  If you own an older home with original hardwood floors, chances are you’ve seen what years of sun damage can do in those sunny places on the floor.  Low-E blocks a majority of the ultraviolet light that can fade rugs, curtains, fabrics and floors, helping to protect your investment for years to come.

3D and 3D Max Energy Packages

For those who want to take energy performance a step further, we offer two energy packages that combine multiple technologies for superior efficiency. These two packages, called 3D® and 3D MAX®, are named because they address energy efficiency through the "three dimensions" of a window: frame, product design and glazing unit. Components in these packages can include technologies such as SunCoat®, SunCoatMAX® Low-E Glass, argon gas, EdgeGard™ and EdgeGardMAX™ spacers. Just ask our salesman for the details!

New Windows Can Pay for Themselves...

According to the U.S. Department of Energy, leaky and inefficient windows, skylights and doors account for up to 25 percent of the average household's energy bills (some sources estimate as high as 40 percent).

By replacing leaky, inefficient windows with modern energy-efficient windows, you not only increase your home’s value and curb appeal, you can cut your home energy costs by as much as 15 percent.
