Energy-Efficient Windows
Time to save energy and save some money! We can help you. 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. . . A lot depends on where you live:

- Cold climates lose energy in the form of heat
- Hot climates lose energy in the form of cooling

Nearly everyone can benefit by replacing leaky, inefficient windows with modern energy-efficient windows. Depending on your location, you can cut energy costs by as much as 15 percent.

Frequently Asked Questions
To help you better understand the parts of the window or door:
Anatomy of windows and doors

I have heard windows referred to as lights, is this another type of window?
Lights (sometimes also spelled lites) are individual panes of glass within a window. Windows are usually designed/measured by the number of “lights” it has in each sash.

What is insulated glass?
Technically, there are two or more panes of glass separated by insulation at the edges and air in the center to provide greater thermal efficiency to a window.

What is a gas-filled window?
Modern window technology permits an inert gas, usually argon, to be sealed between the panes of glass in a window instead of air. The gas is a far better insulator that just air, thus further increasing the thermal value of a window.

What does Low-E stand for and how does it benefit my project?
Low-E stands for low-emissivity, which is the power of a surface to emit heat by radiation. This type of glass cuts the loss of heat during the winter and cuts the absorption of heat during the summer by reflecting the heat back to its source, thus providing year-round savings by lowering utility bills. Low-E glass also selectively filters the sun’s energy, blocking up to 84% of the sun’s ultraviolet rays in the summer, thereby reducing the degree of fading of upholstery, carpet and drapes. Low-E also reduces heating costs reflecting roomside heat back into the room resulting in a lower winter U-value.

U-value - what does this mean? What is its relationship with an R-value rating?
R-value and U-value are reciprocal to one another. The term U-value is measured by the amount of heat that escapes a surface-a wall, ceiling, or window. R-Value is measured by insulation value. How many glass layers there are in a window to the type of gas that is between the panes of glass, are some of the basis of this measurement. The higher the R-value, the better insulated are walls and ceilings. The lower the U-value, the better job a window does in keeping out heat and cold.

What are anodized finishes?
Anodizing is an electro-chemical process that creates a durable finish on aluminum surfaces. It penetrates aluminum like stain penetrates wood, thus preserving the natural beauty of aluminum. It is commonly used in high-traffic a commercial areas that require added hardness and resilience.
