Tooting Library Resplendent in Glazing

Crittall steel windows have been instrumental in the restoration of the iconic and landmark Tooting Library in London. A two year programme to restore the building was completed at the beginning of this year, at a cost of over £3 million. 

The Edwardian structure was originally built in 1902, funded by the generous outgoing mayor of Wandsworth, and today, it attracts over half a million visitors a year. Both the interior and the exterior of the library were in need of an upgrade, and designs were submitted by architects, NPS London Ltd. to bring the facility up to date and in keeping with contemporary, modern energy requirements. 

Externally W20 profiles from the Crittall range were specified to replace the existing steel windows. Slimline and unobtrusive, the profiles provide strength and security, without detracting from the visual appearance of the building.  Crittall was also tasked with replicating certain familiar features. According to project architect, John Miller, the aim was to retain as much of the original architectural style as possible. “Not only were the profiles replicated by Crittall to match, but the company also became heavily involved in the replicated design of the art nouveau-style, floral-patterned leaded lights to a number of the windows on the ground floor,” he explained. This unusual design feature was retained as it was seen as key in retaining the charm and character of the building. 

Similarly, the full height bay window which is a major eye-catching element of the design, involved Crittall’s expertise, with glazing supplied in a wide plate of colours  to create a visually striking effect both inside and out. 

Crittall  also were responsible for the manufacture of exact copies of the original window fittings which were required to add further to the aesthetic goal of the project.   

“The result is exactly as we, and the client, wanted,” concluded Mr Miller. “The windows have been replaced – and some new ones added to the new extension that we have built onto the existing structure – all in keeping with the architectural style of the original.“ 

Crispin & Borst, (now part of Vinci Construction) acted as main contractor on the project. 

Crittall Steel windows - right formula for Science Museum

The Science Museum in London is a much loved and familiar landmark, but over the years, the exterior has fallen prey to the wear and tear. A replacement window programme was recently undertaken, and appointed by architects, Kirsop and Co, Crittall had to draw on its extensive experience and expertise to replace the windows to the Exhibition Road entrance.

Having provided initial elevation and detailed drawings for planning purposes, Crittall helped to obtain permission to the satisfaction of all parties, including main contractor, DBR (London) Ltd, and supplying its Corporate 2000 profiles, began the meticulous and exact replacement programme.



One of the features of the glazing was the inclusion of Enduroshield transparent coating to the surface of the glass for the very large top hung fixed light Corporate 2000 profiles. The openings at the top are supplied with electronic chain actuators, supplied by long term Crittall partner, SE Controls. Double glazed, the centre pane of the glazing achieves the required U value of 1.2w/m2K for compliance with Part L of the Building


Regulations, with Low E glass on the inside to control heat gain. The windows were finished in black matt polyester powder coating.

Logistically, Crittall faced numerous challenges on the project, with a limited time period each day to strip out, glaze and install the profiles. With no deliveries allowed before 6pm, the timing and meticulous attention to detail had to be exact in order for the smooth progression of the instalment. However, with intense planning and thorough application, the windows were installed to schedule and within the time limits.

“We are delighted with the finished result,” comments Mr Andrew Haycock of the Estates Department at the Science Museum. “In addition to brand new windows that meet all the requirements in terms of aesthetic and thermal value, the replaced windows were all recycled, which reduced wastage and disposal costs and which is a major environmental bonus.”

Iconic University Restored

When a replacement fenestration programme was proposed for the iconic Falmer House at the University of Sussex, Crittall was contracted to supply a selection of its Corporate W20 profiles and Corporate 2000 cold form doors for the project.

The building, which houses various University services and the University of Sussex Students’ Union, was designed by famous architect Sir Basil Spence in the 1960s. Brick faced with a vault and column structure and extensive glazing, the unusual building is the first to be seen when entering the campus.

The window replacement scheme is part of a multi mullion pound venture to upgrade the self-contained site, which was awarded a bronze medal from RIBA for its design and architecture and which enjoys a Grade I listed status for a development of exceptional interest. It is also one of the most beautiful campus locations in Britain, being situated in rolling parkland on the edge of Brighton and bordered by the South Downs National Park. The window specification therefore had to be sensitive to the original design criteria and not detract from the visual appearance of the building.

Crittall supplied its Corporate W20 profiles as a like-for-like replacement. English Heritage-approved, the W20 profiles were the ideal choice for the replacement scheme, with the narrow sightlines minimising any obtrusive mullions and transoms, and allowing the glazing to blend unobtrusively into the existing architecture, enhancing its aesthetic value.

In addition, a number of Corporate 2000 windows also being used in Mandela Hall in Falmer House. These were selected as they offer larger panes, meeting the structural requirements for the double glazing.

With Phase 1 of the project completed and Phase 2 already under way, Falmer House is being restored to its former glory with the new windows and doors enhancing the original and innovative Spence architectural design.

In total, the university is investing £100 million through a campus-wide capital programme lasting three years, which will see the University’s facilities and buildings fully rejuvenated.

Old Meets New With Crittall

The Granary in Barking is a stunningly imaginative architectural combination of old and new, and to help with the overall visual impact, Crittall windows have been installed extensively throughout the whole development.

Work to restore the Granary on Abbey Road in Barking began as the first phase of a wider regeneration programme with the Granary and neighbouring Malthouse at the heart of a new quarter for Cultural Industries. The restoration work was undertaken by the Rooff Group, who acted as both developer and principle contractor, and involved the total refurbishment of the building and the design and construction of a new contemporary extension. The building is now the new headquarters of Rooff Ltd as well as providing additional space for other building users. The original concept design was by Schmidt Hammer Lassen Architects, with detailed design by PTE Architects.

The traditional brick facade of the Granary led the architects to specify Crittall W20 profiles, in a design involving multipane horizontal pivot windows with fixed lights. These were suggested to complement the character of the original building. The profiles offer extremely narrow sightlines, minimising appearance whilst providing the required thermal, acoustic and energy efficient performance.

For the new extension, inward opening side hung Corporate 2000 windows were suggested, together with Corporate 2000 doors, which act as a perfect complement to the striking and unusual bronze clad exterior. The slim, elegant rigidity of the steel provides minimum coupling, with no obtrusive transoms or mullions, and is a favourite option for use with curtain walling, as it does not detract from the impact of the facade.

The aim of the design was to preserve the ‘ gritty ‘ character of the site, utilising the appearance of the existing brickwork and enhancing it with harmonising fenestration. The new buildings are of varying heights and scales and the variety of sizes of window profiles correspond to this design, reflecting the urban context and the landscape.

A spokesman from Rooff commented “The existing windows that were replaced on the Granary were also steel, so the Crittall profiles fitted perfectly in context but with updated performance. Using the company’s windows in the new extension shows the versatility of the steel window product range and the ability of the Crittall profiles to blend into any environment.”

Landmark Council Building Restored With Crittall Windows

Grade ll Sessions House in Maidstone, Kent, the headquarters of Kent County Council, has recently been transformed with the replacement of all existing windows with Crittall steel profiles.

The building has recently undergone external refurbishment designed to maintain and enhance its visual appeal while at the same time updating its thermal and environmental performance to meet today's standards.

The existing windows were original single glazed Crittall medium Universal profiles and the Kent County Council's conservation department specified a complete like-for-like replacement. According to Allan Cox, conservation architect responsible for the specification, the decision to retain the same company that manufactured the original was twofold.

"We wanted enhanced performance from the windows," he explained. "Thermally and
acoustically, the profiles had to meet the demands of contemporary legislation but at the same time, there was a keen aesthetic appreciation of the product, in keeping with the history and character of Sessions House. Crittall windows fitted the bill perfectly." The specification took into consideration weather tightness and reduced maintenance costs, and with over 100 years experience in the fenestration market, Crittall recommended its Corporate W20 profiles as the ideal solution. Combining strength with minimal sightlines, the profiles are unobtrusive yet highly efficient and match the originals in terms of style and appearance.

"As headquarters of the local county council, the building is a dominant and important landmark in Maidstone," continued Allan Cox. "The window replacement scheme, which was undertaken in two phases, has rejuvenated the appearance of the structure without compromising or detracting from the original architectural style and we are delighted with our new energy efficient window system."

Crittall's Westminster Winner

Physical performance for the replacement fenestration was put on a par with sympathetic styling by the project team responsible for the conversion of a former Royal Mail building in the heart of London; seeking to create residential accommodation as well as a contemporary design studio with a light and comfortable working environment. 

 

Howick Place in Westminster dates from 1894 and had served as a sorting office until developer, Fabbriche & Ceramiche, purchased the property. The painstaking refurbishment of the premises, led by Squire and Partners, involved Crittall Ltd in supplying some 200 of its Corporate 2000 windows under a sub-contract package for ISG Interior & Exterior Plc.

 

Crittall worked in close cooperation with both the main contractor and the architectural consultants to ensure its high performance steel framed units met the project’s wide ranging requirements; including planning conditions, thermal performance and physical security.

 

 

The project architect at Squire and Partners commented: “I have used Crittall on other contracts in the past and knew they would be one of the few companies able to supply the profile required to match the original fenestration in this building. We also required a high specification in terms of thermal performance and Crittall therefore supplied argon filled 28 mm units to match the requirements of the Building Regulations.

 

“In terms of the design support the manufacturer’s technical representatives responded well when coming back to us with information and possible solutions. This was a major project and the spaces created are very bright and attractive, with the slim window profile offering the maximum transmission.” 

 

The majority of the windows supplied for Howick Place are of the side-hung, open in configuration and were finished in anthracite grey polyester powder coat paint over the galvanised corrosion protection. The sealed units feature a 6.4 mm thick clear laminated inner pane with low-E coating, separated from a 6 mm clear toughened outer pane by the 16 mm gas filled cavity
