Durations' aluminium Royale Stepped steel replacement window is the best on the market, outperforming its competitors not only today, but for the past 12 years.

The window was the first of its kind to compete with steel windows due to its groundbreaking design, high security locking system and impressive thermal performance.

A slim outer frame measuring  just 32mm ensures an authentic steel-look design with the slimmest sightlines on the market.

Traditional styling makes it difficult to distinguish from an original window and it costs a fraction of the price of a steel window.

Royale Stepped windows are made from strong, high-performing aluminium with 18mm-deep double-glazed sealed units. All come internally glazed for easy transportation and delivery and added security.

The slim frame means there is no need to cut back plaster, brickwork, existing or new timber subframes, allowing for quick installation. 

Duration's A-rated window is made to the highest quality using the best materials, supply chain, machines and highly skilled staff.

  • Original versus replacement: the Royale Stepped window has a 32mm deep outer frame and is A-rated for performance.
