General Information
Energy Star
Established by the US Department of Energy and the Environmental Protection Agency, the ENERGY STAR program defines thermal efficiency levels for three different climate regions of the country. The regions are divided by their need for reducing heating costs (northern), reducing cooling costs (southern), or providing the best balance of savings for both (north/central and south/central). Products receive an ENERGY STAR label for the region or regions for which they qualify. It’s easy to remember that WD USA’s windows with the SunPro glazing systems have qualified for the ENERGY STAR label in every region.
NFRC label lets you compare
The National Fenestration Rating Council (NFRC) sets standards for reporting energy performance information based on independent testing, so you can compare windows with confidence. In face, this is the data that the ENERGY STAR ratings are based on. When you compare, you’ll see that WD USA’s windows are among the leaders in thermal efficiency. What’s more, they transmit a high level of visible light for a natural view, and they beat industry standards for air leakage by 100 percent. Learn the measurements that matter:
U-value measures heating efficiency.
This is a window’s ability to block the flow of heat through the glazing system, and retain the heat in the room. The lower the U-value, the better the efficiency. For an easy reference, WD USA’s proprietary SunPro Low “E” glazing system with a low-conductance spacer and argon gas between the panes has a U-value of 0.30, so it is almost twice as efficient as an ordinary double-pane glass system with a rating of 0.50.
Solar Heat Gain Coefficient measures cooling efficiency.
This is a window’s ability to block the infrared heat from the sun, and maintain a cooler temperature in the room. The lower the coefficient, the better. WD USA’s SunPro system has a rating of 0.30, so it is almost twice as efficient as an ordinary double-pane glass system with a 0.58 rating.

Saving America’s Energy with… evolutionary thermal efficiency
Revolutionary Performance and Protection.
WD USA takes great pride in seeking ways to save America’s energy which in turn, saves you, the consumer, money and gives you peace of mind. WD USA distributes windows that are designed to be among the most energy efficient windows on the market. Here’s how…
SunPro Glass System
Low “E” glazing system – the low down on high performance
The latest generation in the evolution of WD USA’s high-performance glazing system options, including proprietary SunPro Low “E” and warm-edge technology keep your home comfortable and energy efficient. The SunPro glazing system meets ENERGY STAR guidelines for energy efficiency in all US climate zones, and these latest advancements deliver optimum performance under the widest possible range of conditions. A combination of an insulating frame and sash, fusion-welded constructions, continuous weather stripping and integral glazing resists air and water infiltration nearly 100% better than the minimum AAMA/WDMA standards.
A detailed system for innovation, quality, and comfort.
SunPro is not an isolated innovation. It’s a uniquely designed system that truly gives you the best balance of performance attributes. An approach in which every detail counts, and combines:
- Multi chambered airspaces and fusion welding in the frame and sashes.
- Double-pane insulating with Low “E” on the inside surface and filled with argon gas.
- Low-conductance material spacer between the two panes.
- The result in increased insulation value, increased warmth, and decreased condensation.
