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.

The cold form steel profiles retain the narrow sightlines and iconic profile providing maximum natural light and excellent thermal properties.

Corporate MW40 steel windows are pressure equalised and double weather stripped for insulation and performance for specification where superior air, wind or water resistance and greater sound attenuation are required.
InnnerVision®: Internal Glazed Screens

Offering a combination of modular or custom sized options with choice of acoustic, privacy and decorative glazing, Innervision allows the designer to create light, open spaces with refreshingly uncompromised design flexibility.
HOMELIGHT Plus: Residential Steel Windows
Crittall Homelight Plus windows provide maximum daylight due to their small profile design, and are designed for applications where smaller typical sizes do not require the weight or depth of the Corporate W20 or Berkeley sections. The slim frame members provide a light delicate feel to the window and the small or horizontal pane options can reflect Georgian or Art Deco styles.

Crittall forges new partnership with Secco Sistemi
Crittall Windows has announced a new strategic collaboration with Secco Sistemi, the renowned Italian manufacturer of high-performance steel windows and doors systems. The partnership represents a further commitment by Crittall to expand its product portfolio and maintain its leadership in the premium market segment.
This new relationship will see Crittall working alongside Secco Sistemi and Barclay Mathieson Architectural (BMA), the sole importer of Secco systems into the United Kingdom. Through this collaboration, Crittall will fabricate Secco’s thermally broken steel systems for both the UK and North American markets. The partnership builds on shared values of quality, innovation and technical excellence.
Secco Sistemi, based near Venice, has been a driving force in steel window and door innovation since its founding in 1947 by Aldo Secco. Known for its use of architectural metals such as brass, corten steel, stainless steel and galvanised steel, the company has consistently produced award-winning systems that combine technical performance with refined aesthetics. Its products have been specified in landmark projects across Europe and beyond, including the James Simon Galerie in Berlin by David Chipperfield Architects.
With more than seven decades of experience, Secco has evolved from its industrial origins to become a highly regarded partner to contemporary architects. Crittall will source Secco profiles and accessories through BMA, ensuring full control over specification and supply. The partnership enables Crittall to bring Secco systems to market with the same attention to detail and project-led service that has defined the Essex-based company for 175 years.
Crittall’s decision to invest in this new product line reflects the business’s long-term strategy of growth through innovation. It complements its in-house range by offering new solutions for high-end residential and commercial projects where thermal performance, material quality and design integrity are essential.
Russell Ager, Crittall Windows’ MD, said: “This partnership allows us to offer a broader range of high-performance steel solutions while staying true to the principles that define Crittall: precision, quality and a clear understanding of architectural intent. It reflects our commitment to evolve with our clients’ needs and to bring new, design-led systems to market without compromise.”
Further details about the new Secco ranges available through Crittall will be shared in the coming months. For now, the announcement marks the start of a collaborative venture between three companies with a shared commitment to excellence in steel fenestration.

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.
