The choice of builders for over two decades.
Walls that disappear? It’s true. Western Window Systems’ Series 600 Multi-Slide Door features large, unobstructed rolling glass panels that stack or slide into pockets for extra wide openings that eliminate the barrier between indoors and out. These moving walls of glass expand living space, frame beautiful views, and let in fresh air and natural light.
Sealed stainless steel ball bearing rollers make the Series 600 Multi-Slide Door easy to operate, even with extreme panel weights. And it features dual-paned low-E glass to reflect heat while allowing light to pass through. Start by choosing the contemporary look of classic aluminum or energy-efficient thermally broken aluminum. From there, a vast range of options lets you customize your functional and aesthetic preferences.
"The fittings and rollers are really gorgeous and highly functional." Whitney Sander, Sander Architects
Designed to seamlessly blend into nearly any space, the Series 600 features a 2.55” interlock stile, wide panels, and modern details that allow for more light and glass.
Sealed stainless steel ball bearing rollers make our 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.
Tested for Durability
Because we build and test our windows to last, you can enjoy your Western Window Systems product for years to come. Manufactured in the U.S., each of our product families is tested for air, water, and structural performance and certified by the NFRC (National Fenestration Rating Council) and AAMA (American Architectural Manufacturers Association).
Climate Ready Glass
Our multi-slide doors feature dual-paned low-E glass manufactured using thermoplastic spacer (TPS) technology for better energy performance. Glass can be customized in a variety of types, colors, and thicknesses for improved privacy, protection, and thermal efficiency.
Concealed Locking System
The Series 600 Multi-Slide Door 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
For strength and durability, Western Window Systems uses stainless steel hardware for its door systems. Rolling hardware is AAMA certified and includes two options: a standard 1.81” size and our 3” Monster Roller, capable of handling more than twice the weight of the largest panel.
Configurations and Sizes
The Series 600 Multi-Slide Door is available in any configuration, with panels up to 84” wide and 144” tall (maximum 60 sq. ft.). For complete flexibility, our multi-slide doors can be designed to do things like go around curves, bypass obstacles, and bi-part in the center. Nearly any shape is possible, including open corners.
Classic or Thermally Broken Aluminum
Classic aluminum is ideal for residential and commercial projects in moderate climates. Perfect for colder climates, our thermally broken option provides the same effortless operation, versatility, and clean aesthetic, but with an insulating barrier that increases energy performance.
Water Barrier Sill
Designed for effectiveness in all climates, the water barrier sill’s 1.5” interior leg and weep-hole system safeguards against water intrusion. For additional protection, the back leg of each sliding panel penetrates the track to help keep out dust and debris.
When ease of entry is more important than performance against the elements, our flush sill is the perfect choice. With an interior and exterior sill height of just .75", it 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 back leg of each sliding panel discourages dust and debris by penetrating the track.
Note: The flush sill is not warrantied against water penetration.
The ability of our signature Thinline Sill to disappear 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 is not warrantied against water penetration.
"People are just bowled over by the space. The walls just disappear when they're open." Dr. Teryn Clarke
OptionsHandles and Locking
The standard choice for all Western Window Systems’ multi-slide doors, the flush-mounted handle’s clean, narrow design allows panels to 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.
Our optional premium 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 choices are available in brushed nickel or black. The premium handle is not available on pocketing multi-slide door systems.
