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.

Respectful Remodel

Clean Design

Designed to seamlessly blend into nearly any space, features interlock stile, wide panels, and modern details that allow for more light and glass.

Smooth Operation

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 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

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

Multi-Slide Doors are 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.
