Corporate W20 windows and doors offers great versatility. No other steel window system offers such an extensive range of sections, allowing the designer the opportunity to create many styles including elaborate composite windows.
An effective weatherstripping system, and the option of double glazing up to 14mm when gasket glazed, and 16mm wet glazed ensure excellent thermal insulation properties, and the system’s large opening casements and slim frame make it particularly popular with conservationists and planners.

Crittall House of the Year Awards 2025: Finalists Revealed
The shortlist for the 2025 Crittall House of the Year Awards has been unveiled, with three standout residential projects named as finalists. Now in its sixth year, the awards recognise the best use of Crittall’s iconic steel windows, doors and internal screens in UK homes.
Open exclusively to Crittall’s specialist partner network, entries are judged on installation quality, architectural integration and the creative use of steel to shape contemporary and heritage spaces.
This year’s finalists range from a crisp modern renovation in Sheffield to a meticulous restoration in rural Sussex and a technically ambitious project in South West London. Each demonstrates the power of steel to bring structure, rhythm and light to residential architecture.
A sensitive restoration in Mid Sussex
Partner: Lightfoot Windows
Modern property exterior featuring black crittall windows and doors with glass balustrade balcony This partly 14th-century listed property on a Sussex high street has undergone a considered transformation to become a forever home.
The building had been altered repeatedly over the years, obscuring original features and interrupting its flow. The owners stripped it back, reconfiguring the space while adding a light-filled extension.
From the outset, they were committed to using Crittall throughout, for its technical quality and its ability to tie together old and new.
The final scheme includes eight units: external W20 windows and doors, fire-rated screens, InnerVision partitions and a dramatic 4.5m-high raked screen at the rear. Brown (RAL 8080) was chosen to soften the look and unify the palette.
“The difference in finishing quality was night and day,” the owners said. “Crittall has helped link everything together. The glazing avoids making the new extension feel like a bolt-on.”
With its clean lines and subtle detail, the steelwork sits comfortably within the historic structure, bringing light, balance and a renewed sense of coherence.
A modern renovation in Sheffield
Partner: KJA Services
Modern property with white facade, featuring crittall steel windows and doors Set in an elevated position with expansive views, this Sheffield home has been reworked to create a more open, connected and characterful living space.
The homeowners were first introduced to Crittall during a stay at the Soho Hotel in London and were immediately drawn to its distinctive feel.
What started as a plan for a few key windows grew into a full-house scheme. The final result includes external steel windows and doors plus a bespoke internal shower screen, all in Black Grey ( RAL 7021).
“Everyone compliments the Crittall windows and doors; it’s the first thing people mention,” said the homeowner. “They were definitely our best investment during the renovation.”
The steel glazing feels entirely at home within the contemporary architecture, enhancing its form without overpowering it.
A refined renovation in South West London
Partner: Bespoke Glazing Design
Design team: ADE Architecture and Sarah Brink Design
This South West London project pairs design ambition with technical control. At its centre are bespoke Crittall pocket doors – a rare feature in residential settings – designed to deliver both architectural weight and flexibility.
When closed, the doors frame each space with strong lines. When open, they vanish into the walls, creating uninterrupted flow. Achieving this demanded detailed coordination between design, glazing and construction teams.
“Each time we pass through those doors, there’s a moment of transition that feels purposeful,” said the homeowner. “It’s a reminder of how good design can shape how we live.”
The use of Crittall here goes beyond aesthetics. It plays a key role in shaping how the house is used and experienced day to day, room to room.
Winner announcement
The winner of the Crittall House of the Year Awards 2025 will be announced on our website and in the September issue of Kitchens Bedrooms & Bathrooms magazine, on sale from 5th August.
New RIBA-approved CPD from Crittall Windows explores 21st-century steel solutions
Crittall Windows, the UK’s leading steel window and door manufacturer, is running a new RIBA-approved CPD seminar designed to support architects and specifiers working across both restoration and contemporary design projects.
Titled Steel Windows and Doors for the 21st Century, the CPD offers a practical and in-depth guide to specifying steel. It provides essential knowledge around design, construction methods and emerging technologies, giving professionals the confidence to integrate steel solutions into a wide variety of building types.
The course is available either face to face at Crittall’s headquarters in Essex or delivered online for practices across the UK. In both formats, sessions are led by experienced Crittall personnel who bring decades of technical and design insight to the table.
As the original pioneer of steel windows in Britain, Crittall has a deep and unique understanding of the material’s enduring value. The CPD covers the distinctive properties of steel that make it a compelling choice for both external windows and doors and interior applications such as partitions and screens. Emphasis is placed on performance, longevity and sustainability – topics increasingly relevant to modern architectural practice.
Two structured modules are available. The first focuses on the specification of exterior steel windows and doors, including compliance, performance and aesthetic considerations. The second addresses the use of steel for interior glazing, now a hallmark of high-end residential, retail and commercial interiors.
As a recognised RIBA CPD Provider, Crittall’s course is listed on both the RIBA and NBS platforms, ensuring easy access for registered practices. The seminar has been developed to meet current learning needs in a competitive design and construction landscape.
Russell Ager, MD at Crittall Windows, commented: “We know that specifiers value clear, informed guidance when choosing materials. This new CPD shares the knowledge we’ve built over more than 170 years and brings it right up to date with the latest steel solutions for today’s projects.”
