Like Steel. Unlike Anything Else.
Embodying nearly 60 years of advancements in door and window design, our thermally broken simulated steel line of moving glass walls and windows reaches new heights of luxury and refinement. Of course, the elements that make Western Window Systems a top choice among architects — clean, narrow profiles to keep glass big and maximize the amount of natural light — are still unmistakable.
Customized to Your Vision
From traditional projects with factory-style windows and doors to modern minimalist looks featuring large panes of glass, you’ll find nearly limitless expression with our simulated steel line. Choose made-to-order moving glass walls and windows that, thanks to a signature design, can go taller and wider than you’d expect. Options such as split finishes, screens, and hardware allow for even more design flexibility.
Built with a signature aluminum extrusion design, across-the-board low U-value ratings, and low-E, argon-filled dual-pane glass, Western Window Systems’ thermally broken simulated steel line is all about reducing energy consumption. A proprietary Insulbar profile assists in increased thermal performance and strength. All product families are NFRC-tested to a design pressure rating of 50 and support laminated and security glass essential for noise reduction.
Faster, Easier, and More Affordable
Unlike steel doors and windows that can cost double the price of aluminum, require field glazing, and include lengthy lead times, Western Window Systems’ simulated steel line is all about inspiration, efficiency, and value. Of course, there’s a price advantage — but there also are completely customizable products, short production lead times, and pre-glazed systems to reduce handling and installation time.
Make a Statement on an Epic Scale
Designed around narrow sightlines, beveled glass stops, and coped muntin bars, our simulated steel line replicates the existing steel profiles used in many historic buildings, universities, and commercial projects. Thermally broken aluminum, low U-values, and superior design pressure ratings mean you have the strength and performance to bring your biggest ideas to life.
The Features You Want, the Capabilities You Expect
Narrow, Clean Profiles
Decidedly design-forward, the simulated steel line is all about detail, such as beveled glass stops and .875” simulated divided lites (SDLs) designed to emulate a steel putty glaze.
Options from Cardinal IG include laminated glass, solar- and glare-control glass, enhanced winter performance glass, and low-maintenance glass.
Available in-stock, as designer selections, or customized to match any color.
Simulated steel doors and windows easily integrate to form a unified look.
