W20 TE’s versatility in Victorian, Art Deco and Brutalist projects

The sheer number of architectural styles to be seen in the UK – some dating back to the medieval era and even beyond – can be a real challenge for the architect or specifier who needs to balance modern demands with the preservation of character.

This really matters when it comes to windows. The glazing of today must meet high thermal performance standards while not looking out of place, especially in an older or listed building. Luckily, Crittall’s W20 TE steel windows meet that brief with distinction, offering modern performance wrapped in timeless Crittall design. From elegant Victorian villas to rugged Brutalist blocks, this thermally enhanced steel system adapts with ease.

Victorian charm with contemporary performance

The Victorian era brought with it an eclectic style, embracing ornamentation, stained glass and gothic influences. Bay windows, coloured glass and decorative ironwork were common in domestic settings, while civic buildings often featured large steel-framed windows to maximise light.

Crittall’s W20 TE windows respect this traditional feel while introducing cutting-edge performance. The inherent strength of Crittall steel profiles supports larger openings without visual bulk, while dual weather seals guarantee superior weather performance. With a life expectancy exceeding 60 years, the system is designed to handle the demands of everyday use while maintaining a touch of classic elegance.

Art Deco elegance meets steel innovation

The Art Deco period (1920s–1930s) is celebrated for its clean lines, geometric shapes and luxurious materials. Architecture from this era often featured bold, streamlined designs and expansive windows that flooded interiors with light. Whether used in cinemas, department stores or private residences, Art Deco windows were a central part of the design, characterised by their emphasis on symmetry, elegant proportions and the use of steel and metal framing.

Crittall’s W20 TE steel windows fit seamlessly within this aesthetic, offering the sleek lines and high-performance credentials that Art Deco buildings demand. The system’s slim sightlines and ability to create large openings without compromising structural integrity make it ideal for maintaining the strong geometric forms associated with Art Deco windows. The added benefit of impressive energy efficiency and weather protection makes the W20 TE a perfect choice for both restoration projects and new builds inspired by this iconic style.

Brutalist strength meets minimalist detailing

Brutalist architecture emerged in the mid-20th century, characterised by its use of raw concrete, exposed structure and functional design. Fenestration in these buildings was often stark, sometimes oversized, and always intentional. Clean lines, strong geometry and structural honesty were key themes.

The W20 TE steel window system is a natural fit. Its minimalist aesthetic, flexible installation options and high-performance credentials allow architects to retain the integrity of Brutalist projects while upgrading to modern standards. Whether used in a residential project, cultural space or adaptive reuse scheme, these beautiful steel windows deliver robustness of steel and design flexibility in equal measure.
