WWS Wins Best Metal Windows
New Single-Hung and Sliding Window
Created with Energy Efficiency in Mind

Clean Design

Designed with a 4.5” frame depth, windows can be directly mulled to most of Western Window Systems’ product lines such as hinged doors, sliding doors, and fixed window walls.

Sloped Sill

For improved water drainage, each window style in the Series 670 line includes a sloped sill.

Thermally Broken Aluminum

Thermally broken aluminum provides an insulating barrier that increases energy performance.

Designed and 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

Features 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.

Casement Windows

The Series 670 Casement hinges on the side, swings outward to the left or right, and provides excellent ventilation. Thermally broken aluminum and dual-paned low-E glass keeps it energy-efficient. A sloped sill improves water performance. Countless sizes and finishes let you customize as you see fit. And because it’s aluminum, the Series 670 Casement is also low maintenance.

Push-Out Casement

The Series 670 Push-Out Casement combines the traditional appeal of a push-out window with modern efficiencies. It opens easily with the turn of the handle and a light push. Thermally broken aluminum and dual-paned low-E glass keeps the Series 670 Push-Out Casement energy-efficient. A sloped sill improves water performance. Countless sizes and finishes let you customize as you see fit. And because it’s aluminum, it’s low maintenance.

Window Wall – Integration meets imagination.

What’s in a name? Everything. The Series 600 Window Wall replaces exterior barriers with expanses of glass that let in light and frame beautiful views. Completely customizable, a limitless array of openings – from single-panel to door-size to openings that span an entire wall – allow you to create views from various sizes and shapes of glass. And because the Series 600 is designed to integrate with various ventilating window styles as well as our hinged and sliding doors, it’s flexible as well as functional.

Start by selecting your Series 600 Window Wall in classic aluminum or energy-efficient thermally broken aluminum. Dual-paned low-E glass reflects heat while allowing light to pass through. Sill and stop options and countless sizes, configurations, and finishes let you customize as you see fit. And because the Series 600 is aluminum, it’s low maintenance, too.

Clean Design

The mulling process for the Series 600 Window Wall combines window frames while keeping sightlines narrow, resulting in a clean, contemporary look that can be replicated through an entire wall of glass.

Seamless Integration

The Series 600 Window Wall’s versatile 4.5” deep framing system allows our Series 900 Hinged Doors, Series 600 Sliding Glass Doors, and Series 670 hinged windows to directly mull to any combination of windows, creating a clean, smooth appearance.

Tested for Durability

Fixed Series 600 windows mounted in the structure on all four sides achieve a performance grade of CW-PG50 at sizes up to 60″ x 120.” (CW-PG50 includes a design pressure of 50 pounds per square foot, the equivalent of 140 mph winds.)

Steel Support

For certain wind load requirements, Western Window Systems reinforces the cavity of the mull on its window walls with steel for additional strength and support.

Classic or Thermally Broken Aluminum

Western Window Systems’ aluminum Series 600 Window Wall is ideal for residential and commercial projects in moderate climates. Perfect for colder climates, our thermally broken aluminum provides the same effortless operation, versatility, and clean aesthetic of our classic aluminum option, but with an insulating barrier that increases energy performance.

Climate Ready Glass

The Series 600 Window Wall features 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.

Configurations and Sizes

Featuring countless extrusion styles, the Series 600 Window Wall can be designed to nearly any configuration and size. Standalone units are tested to 50 DP. For larger expanses, steel can be added when mulling for increased strength. Fixed windows can be built to nearly any geometric configuration, including arches, circles, and polygons. The Series 600 Window Wall is designed to integrate with various ventilating window styles as well as our hinged and sliding doors.
