What Architects are saying about Western Window Systems’ Performance Line

As the call for more contemporary housing broadens, architects continue to search for larger size aluminum moving glass walls and windows with high energy and structural performances. Western Window Systems’ Series 7000 Performance Line is a great option for the increasing trend.

For The New American Home 2020, a yearly showpiece at the International Builders’ Show, architect Dan Coletti of Sun West Custom Homes in Las Vegas utilized the Series 7600 Multi-Slide Door to achieve National Green Building Standard “Emerald” certification.

“Western Window Systems’ Series 7600 is such a high performer,” Coletti says. “I remember when we were doing a Model Energy Code analysis, how great it was. It was amazing that we were able to put a lot of multi-slides in and still meet the energy objectives we were chasing.”

It wasn’t the first time Coletti specified high-performance doors and windows for a showcase home. The New American Home 2019 also features the Series 7600 Multi-Slide Door and massive amounts of glass. The doors work in tandem with the home’s deep overhangs to create a highly energy-efficient residence. “With the Series 7600 being so energy efficient, it expanded our ability to use even more glass where we want it,” Coletti says.

In addition to energy efficiency, Western Window Systems’ Series 7000 Performance Line delivers on aesthetics and functionality – something architect Jason Winters of Kezlo Group needed when remodeling a Maryland home outfitted with standard windows measuring 6 feet wide by 9 feet high. “The owner was insistent that the windows be operable,” Kezlo says. “So, we had to make that happen without losing the aesthetic of the thin black frame.”

“Those were very heavy units, but they all easily open so that you can get cross-breeze from the north side of the house,” he continues. “With Western Window Systems, we didn’t have to sacrifice aesthetics for operability.”

Available in a wide variety of sizes and custom configurations, sliding and folding doors in the Series 7000 Performance Line boast precision hardware like signature aluminum extrusions, interlocking track design, and the optional Quad-Zilla Roller, capable of handling extreme panel sizes and heavy glass types.

Specific ratings vary by custom order and application, but every product in the Series 7000 Performance Line:

  • Has low U-values and Solar Heat Gain Coefficient (SHGC) ratings
  • Features Energy Star-qualified options
  • Uses climate-ready, Low-e, argon-filled, dual-pane or triple-pane glass
  • Includes thermally broken aluminum frames
