Our strongest and most energy-efficient design ever.
Embodying nearly 60 years of advancements in multi-slide door design, the Series 7600 is packed with innovations that address energy and structural requirements. Of course, the design elements that have made it a favorite with architects — thin profiles and large, unobstructed rolling glass panels that stack or slide into pockets — are still unmistakable.
A .30 U-value for standard, low-E, argon-filled dual-pane glass makes the Series 7600 able to deliver energy efficiency in a variety of weather conditions. And because it’s available in the most sizes and configurations of any brand, there are infinite ways to customize.

"The products are durable, energy efficient, well-crafted, and beautifully engineered.” Katie Reibel, owner/designer, Simply+Modern
Energy Efficiency
To deliver energy efficiency in a variety of weather conditions, the Series 7600 has a .30 U-value for standard, low-E, argon-filled dual-pane glass. Plus, it’s compliant with California’s rigorous Title 24 requirements in both the prescriptive and performance methods.
Climate-Ready Class
The Series 7600 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.
Bigger Sizes
Offering some of the biggest sizes of any brand, the Series 7600 is available in heights up to 15 feet in most markets. Choose from pocketing, non-pocketing, and bi-parting configurations. There’s even a 90-degree option that completely opens up the sides of a room by eliminating a connecting post.
Clean Design
An interlock stile with a narrow 2.9” width keeps lines clean and glass big.
Smooth Operation
Sealed stainless steel ball bearing rollers make our aluminum multi-slide doors easy to operate. An interlocking track design provides structural integrity and makes it possible to span wide openings with almost any number of panels.
Concealed Locking System
The Series 7600 includes a hidden stainless steel multi-point lock to secure its large sliding panels, providing additional strength and protection. A keyed cylinder option is available.
Heavy Duty Hardware
Rolling hardware includes two options: a standard 1.81” size and our signature Quad-Zilla Roller, capable of handling extreme panel sizes and heavy glass types.
Tested for Durability
The Series 7600 Multi-Slide Door features a design pressure (DP) rating of 50 and is certified by the NFRC and AAMA.
Energy Star Rated
The Series 7600 Multi-Slide Door features Energy Star-qualified options. Contact us for assistance.


Oversize Glass
No longer requiring a sacrifice of either size or energy efficiency, oversize glass panels for the Series 7600 Multi-Slide Door make breathtaking views look better than ever. From Minnesota-based Viracon, they’re available in sizes up to 17 feet tall and boast a low-E coating that increases thermal efficiency across climate zones. Offered with a ten-year warranty.

Water Barrier & High-Performance Water Barrier Sills
Our water barrier sills are available in two different sizes and pressure ratings. A weep-hole system helps to safeguard against water intrusion. For additional protection, the legs of each sliding panel penetrate the track to keep out dust and debris.

Flush Sill
With an interior and exterior sill height of just 0.75", the flush sill lines up with most interior flooring for a smooth transition to the outside. Weep holes in the track allow water to drain away from the door while the legs of each sliding panel discourage dust and debris.
Note: The flush sill may be less effective at preventing water penetration than the high-performance water barrier sill and may not be appropriate in all climates, conditions, and exposures.

Thinline Sill
The ability of our signature Thinline Sill to hide almost completely makes it ideal for projects where a continuation of flooring from the inside to the outdoors needs to appear virtually seamless. Staggered tracks expose a slim channel on which the panels roll, with the finished floor installed between them.
Note: The thinline sill may be less effective at preventing water penetration than the high-performance water barrier sill and may not be appropriate in all climates, conditions, and exposures.
"The large doors make our home feel so much larger and inviting by incorporating natural spaces.”Suzanne French, homeowner

Flush-Mounted Handle
The standard choice for all Western Window Systems multi-slide doors, the flush-mounted handle’s clean design lets panels easily slide past each other or into a pocket. An optional keyed cylinder allows the door to be unlocked from the exterior. Finish choices are available in brushed nickel or black.

Contemporary Handle
Our optional contemporary handle features a minimal one-piece design, comfortable grip, and the option of a keyed cylinder that allows the door to be unlocked from the exterior. Finish is available in brushed nickel or black. The contemporary handle is not available on pocketing multi-slide door systems.
"Western Window Systems products fit very well with our design philosophy. We continue to specify them for their high-quality hardware and very large allowable glass areas.”D'Arcy Jones, principal, D'Arcy Jones Architecture
