The Zen FPS50 Slimline Tube Steel Window system is designed for projects that require refined sightlines, structural reliability, and flexibility across a wide range of architectural applications. Suitable for fixed windows only FPS50 is a popular choice for larger fixed window applications.
Manufactured from cold formed tube steel, the FPS50 profile achieves a slim and elegant appearance while retaining the strength needed for larger spans and generously glazed openings. Its proportions make it ideal for both residential and commercial architecture, whether used as individual feature windows or as part of a broader integrated steel door and window package.
A major advantage of the FPS50 system is its polyurethane injected profile construction, which enhances insulation and contributes to improved thermal efficiency. This gives FPS50 excellent thermal properties compared to conventional non-thermally enhanced steel systems, making it well suited to projects where comfort, energy performance, and visual consistency are all important.
The result is a steel window system that balances architectural lightness, robust performance, and long-term durability. For architects, builders, and homeowners seeking slimline steel windows with strong thermal properties and broad design versatility, FPS50 offers a highly refined and capable solution.
