Duration Windows sets new standard with Royale Stepped Window

A UK-based manufacturer is redefining the steel replacement window market with its industry-leading Royale Stepped Window, which has been outperforming competitors for over a decade. Duration Windows has positioned itself as a leader in the field, delivering a high-quality, high-performance alternative to traditional steel windows.

The Royale Stepped Window was the first of its kind to rival steel windows due to its sleek design, robust security features, and exceptional thermal efficiency. Central to its appeal is its ultra-slim 32mm outer frame, offering the narrowest sightlines on the market. This ensures an authentic steel-look aesthetic that blends seamlessly with traditional and modern properties alike.

Constructed from durable, high-performing aluminium and featuring double-glazed sealed units just 18mm deep, the window offers an ‘A’ energy rating and is built for longevity. The internally glazed design enhances security and allows for ease of installation, enabling it to be fitted directly into existing timber subframes or onto brickwork without requiring extensive alterations.

Durations’ commitment to quality is further exemplified by its 10-year warranty and customisation options. Customers can choose from over 200 RAL colours, single or dual tones, and seven different glass designs, including square or diamond leaded glass and flat or horizontal astragal bars. A selection of locking handle designs, peg-and-stay handles, and hinges ensures compatibility with a range of architectural styles.

With its competitive pricing and heritage-friendly features, the Royale Stepped Window is gaining traction among homeowners, developers, and conservationists. Particularly suited for listed buildings, conservation areas, and period properties, it offers a stylish yet practical solution for those seeking to preserve historical charm without compromising on modern performance.

As the demand for steel-replacement windows grows, Durations continues to lead the market with innovation and craftsmanship, solidifying its reputation as the go-to provider for high-quality aluminium alternatives.
