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.

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. 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).

Thermally Broken Aluminum

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

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.

Window Wall
Integration meets Imagination

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.
