An entirely new kind of patio door.
The Series 7650 Sliding Glass Door is more than the next generation of patio door — it’s a performance-focused solution for contemporary living spaces.
Our strongest and most energy-efficient aluminum sliding glass door ever, it features an energy-efficient .30 U-value for standard, low-E, argon-filled dual-pane glass, a design pressure (DP) rating of 50 for strength against the elements, and a modern sill option that creates a cleaner and smoother transition from the indoors to the outside.
Available in sizes that are taller and wider than you might expect, the Series 7650 is all about completely customizable options to fit your tastes and home design.

"Western Window Systems has that contemporary aesthetic and offers a lot of flexibility. They offer much larger windows than what you'd have in a typical system.”Jason Wolfe, vice president, Demerly Architects
Energy Efficiency
Featuring a .30 U-value for standard, low-E, argon-filled dual-pane glass, and a .19 U-value for high-performance triple-pane glass, the Series 7650 is able to deliver energy efficiency in a variety of weather conditions. A signature aluminum extrusion design utilizing proprietary Insulbar technology further reduces energy consumption. NFRC certified and compliant with California’s rigorous Title 24 requirements.
Climate-Ready Glass
The Series 7650 comes standard with Cardinal IG’s all climate coated or high-performance glass that delivers solar control and high visibility. Glass can be customized in a variety of types, colors, and thicknesses and includes options such as laminated glass, solar- and glare-control glass, enhanced winter performance glass, and Neat low-maintenance glass. Pre-applied Cardinal Preserve film protects glass through installation.
Clean Design
With features such as a narrow 2.9” interlock stile, a modern sill option, and design elements such as jamb covers (which hide exposed fasteners), consistent sightlines, and a concealed locking system, the Series 7650 Sliding Glass Door maintains a minimalist aesthetic. Engineering efficiencies eliminate the need for a bulky interlock, allowing panels to neatly stack in alignment.
Bigger Sizes
Able to go taller and wider than most brands on the market, the Series 7650 is available in heights up to 15 feet in most markets.
Smooth Operation
Rolling hardware includes a standard 1.81” tandem roller and our signature Quad-Zilla Roller, capable of handling extreme panel sizes and heavy glass types.
Heavy Duty Hardware
Western Window Systems uses stainless steel hardware for its door systems.

The Series 7650 Sliding Glass Door features a design pressure (DP) rating of 50 and is certified by the NFRC and AAMA.

The Series 7650 Sliding Glass Door comes standard with a 1.5” sill. For increased effectiveness against the elements, 2” and 2.6” options feature a higher interior leg. The 1.5”, 2”, and 2.6” sills meet the commercial specifications of the American Architectural Manufacturers Association (AAMA) and boast a performance rating of DP50. A flush sill option that lines up with most interior flooring is also available. All sills are finished to match the color of the frame.
"We wanted to bring the outdoors inside. That was one of our key goals: minimizing the amount of obstruction to view with big expanses of glass and thinner mullions, which you didn’t have 50 years ago.”Doug Austin, architect, AVRP Studios

Flush-Mounted Handle
The flush-mounted handle is designed to integrate into the panel for a clean aesthetic. An optional keyed cylinder allows the door to be unlocked from the exterior. Finish choices are available in brushed nickel or black.

Contemporary Handle
