Can I order a window to fit any opening?

Yes, however, in some cases you might have to order multiple windows to fill one opening. Some openings are just too big, and may require multiple windows joined together to fill the opening. There are standard windows sizes that accommodate the majority of applications, but many openings will require custom sizing.

What is insulated glass?

Insulatedglass consists of two pieces of glass sealed to a spacer. This creates an insulated air space between the two pieces of glass, resulting in better thermal performance. Insulated glass also reduces condensation while keeping the heat in during the winter, and heat out during the summer.

What is Low-E Glass?

Low-E Glass is coated with a virtually invisible layer of silver that reflects radiant solar energy while permitting visible light to pass through the glass.

In cold, winter climates, the Low-E Glass helps keep rooms warmer by reflecting heat back into the home while letting warm, solar rays in. In hot, summer temperatures, the Low-E Glass lets visible light pass while blocking infrared and ultraviolet radiant solar energy. So your rooms stay cooler and you save on precious energy costs.

What is Low-E Glass with Argon Gas? How does it work?

Added inside an insulated panel with Low-E Glass, Argon gas is an invisible, insulating blanket that replaces most of the air during the manufacturing process. With Low-E reflecting heat away, Argon gas buffers thermal transfer to enhance the performance of the whole glass panel.

How should I evaluate the energy performance of a window or patio door?

Look for the National Fenestration Ratings Council (NFRC) label on the window or patio door. This label shows the U-Value, Solar Heat Gain, and visible light transmittance values.

What is Energy Star®? What qualifies your products?

Energy Star® is a national campaign sponsored by the EPA and the Department of Energy to promote energy efficient products. The endorsing logo may be found on computers, appliances, or power tools. Any product that uses or affects energy may have an Energy Star® rating.

What does R-Value and U-Value mean?

R-Value is a term that measures the insulation properties of a material. For example, fiberglass insulation is measured by ‘R-Value’.

The energy efficiency of windows is measured by ‘U-Values’. Because windows are not insulators by design, they cannot be measured in ‘R-Values’. However, windows obviously have insulating properties, so there needs to be a measurement that allows comparison of styles and window packages.

There is a relationship between R-Values and U-Values. Whereas the higher the R-Value, the greater its insulating ability, the lower a U-Value, the better that product’s insulating efficiency. To find a U-Value, divide the number ‘1’ by the R-Value. For example, an R-Value of ‘4’ is equal to a U-Value of .25.
