50CW Curtain Walling
The Kestrel aluminium 50CW is a high‑performance curtain wall system developed to meet the demands of modern commercial and mixed‑use buildings, from ground floor applications through to high‑rise projects.
Tested to BS EN 13830, it delivers excellent resistance to wind, water and air infiltration, alongside strong thermal performance, with Uf values as low as 0.88 W/m²K. Designed with fabricators in mind, the transom‑to‑transom façade approach, shared mullion and transom profiles and a single universal glazing gasket help reduce material waste, simplify stock management and speed up fabrication, while integrating seamlessly with Kestrel’s wider window, door and ground floor systems for a consistent façade solution.
Features and benefits
We understand that efficiency in the workshop is just as important as performance on-site. The Kestrel 50CW features several innovations designed to save time and reduce costs:
- Weather resistance: Rigorously tested to BS EN 13830 standards and featuring a proven mullion/transom joint design, it delivers industry-leading protection against wind, water, and air infiltration.
- Thermal efficiency: The system achieves thermal properties as low as Uf 0.88 W/m²K, providing excellent insulation and compliance with strict energy regulations and sustainability targets.
- Precision engineering: Our flex injection assembly process ensures precise, reliable sealing at every joint, optimising long-term performance.
- Universal glazing rebate gasket: With a single glazing rebate gasket working across the system, the number of components you need to keep in stock is reduced, simplifying your stock management.
- Ease of installation: The innovative transom-to-transom design significantly reduces material waste and simplifies the cutting process.
Design options
The 50CW is designed to be part of a complete building envelope. It integrates flawlessly with our existing product range to provide a consistent visual finish across the entire project.
- Slim sightlines: The 50 mm face width maximizes natural light and provides a sleek, modern aesthetic.
- Versatile infills: Glazing or panels from 26 mm to 56 mm can be accommodated, with weights up to 1000 kg.
