Silent Witness - Crittall Windows Steel The Show

On Friday 18th January, the latest episode of Silent Witness showed scenes shot around London University's School of Oriental Studies, where Crittall Windows has recently completed a replacement windows scheme in partnesrship with Overbury.

In the words of Alan Ivory, the Overbury Site Manager, "Take a look out in the background, and you might see some of that great repointing on elevation B that was done by Eddie from PAYE, as well as, of course, the sparkling Crittall windows.

The whole episode can be viewed on BBC iPlayer...

Crittall windows for Iconic London landmark

The Old Building at the prestigious School of Oriental and African Studies in London has a new appearance, thanks to a replacement window scheme involving Crittall Windows. The original building on Russell Square was designed in the late 1930s by Charles Henry Holden, best known for his designs of underground stations.

Being Grade II listed, the upgrade specified like for like replacement - and in this case, this involved the removal of existing Crittall steel profiles from their decaying timber subframes and the installation of new high performance steel Corporate W20 units.

The scheme is part of an on-going plan to upgrade the SOAS campus, with the new Crittall windows serving a dual purpose; maintaining the overall visual appearance of the architecture and significantly improving the thermal performance. As the doors and windows span five storeys, new double glazed contemporary windows that comply with stringent conservation and environmental requirements will make a noticeable difference on heat gain and maintenance costs. In addition, they provide a timeless aesthetic quality to the architecture, without overshadowing the prominence of the structure itself.

A selection of side hung and open out vents were installed, together with horizontal and vertical pivots, louvres and fixed lights, all in a uniform RAL cream colour to heighten the visual appeal.

Architects Kendall Kingscott were responsible for the project with Overbury appointed as main contractors. The work was completed on time and to schedule, with the Crittall installers managing the work so smoothly and deftly that they were awarded Overbury's contractor of the month award for their  'flexible approach and professionalism '.

Crittall Windows Shut Out Super Storm Sandy

Eldorado residents are not counting the cost of the big clean up after Hurricane Sandy.

Residents of the Eldorado Building at 300 Central Park West, New York City, who have replaced their windows with Crittall, can congratulate themselves for making a great choice.

Crittall's partner, Industrial Window Corp and local Distributor, Robert K Higgins Company Inc have just received this endorsement from a Resident:

"Jim,

If there was ever a torture test for these windows, this Hurricane Sandy would be it, I think I should let you know, that every single window "held", no leaking.

I was lucky to get it all done before this storm, the old ones would have leaked like a sieve!

Anyway, just a note to let you know I appreciate a good job!"

Crittall Windows Archive Secrets To Be Revealed

Crittall Windows Ltd, Braintree District Museum Trust Ltd and Braintree District Council are excited to announce a joint project to research and develop the Crittall company archive held at Braintree District Museum.

The Archive contains over 2,000 documents, catalogues and photographs illustrating the growth and development of a local ironmonger to worldwide window manufacturer. The project will fund a young apprentice, Richard White, who will be cataloguing the Archive to improve access and knowledge of this internationally significant collection.

By the early twentieth century, Crittall Windows had become a worldwide window manufacturer with factories and agents from South Africa to Australia. Further funding will be sourced in 2013 to develop an online database of the Archive. Crittall Windows was a larger employer in Braintree and by the 1920s employees and their families accounted for over half of the town's population. If you or a member of your family worked for the company, we would like to hear from you.

On Thursday 29 November from 2.30 - 4pm the Museum will be holding an event 'Collecting Crittalls'. If you would have any objects, documents or photographs you would like to donate to the Crittall Windows Archive please come along. We are particularly interested to hear from people who worked abroad for the company.

Councillor Jo Beavis, Cabinet Member for Communities was delighted with the development of the Archive as "it will be a wonderful opportunity for our modern apprentice to explore such an important part of Braintree District's history. It is a great example of partnership work between the Museum and a manufacturing company based in this District"

Crittall Windows Head of Manufacturing on C4 News

Steve Gaylor, the Head of Manufacturing at Crittall Windows was recently interviewed by Channel 4 News

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. 

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.”

Carnival Time in Witham

Crittall Windows are pleased to support Witham Carnival, and Witham Kids Club, by providing a lorry to be used as a float in this year's Carnival Procession.

The members, parents and organisers of Witham Kids Club did such a great job of transforming our lorry into Never Never Land, that they won the award for the Best Decorated Trade Vehicle.

Congratulations everyone for making our lorry even more attractive than it usually is!!

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

 

Crittall Windows Retain the City Character

95 Gresham Street is a gem in the heart of the City of London. The £35 million refurbishment of the site makes extensive and impressive use of glass and steel to contrast with the existing external facade of Portland Stone. And for the glazing element, Crittall Windows supplied and installed its Corporate 2000 and W20 profiles for optimum visual impact and long lasting performance.

The original structure has been redesigned to offer eight floors and 95,000 sq ft of office space, with a brand new atria created as a main focal point at the entrance. The installation of the new windows was a like-for-like replacement, with the Crittall profiles helping to retain the character and traditional appearance of the external facade, whilst at the same time providing modern, advanced glazed units that comply with all thermal and energy efficient requirements.

Crittall’s involvement extended beyond just supplying the profiles, as architect, George Corrigan of architects, Rolfe Judd explained. “95 Gresham Street actually comprises both Princes House and Bartlett House,” he said. “One of the tasks that Crittall Windows was faced with was to refurbish the cast iron framing and panels to some of the fenestration in Bartlett House prior to installing the new profiles. This was done successfully, with the rest of the replacement window project completed on time and to the standards required for this conservation area. Crittall’s ability to offer this complementary service greatly contributed to the smooth progression of the scheme.”

The modernisation of 95 Gresham Street has now been completed and the result is a complete transformation of the site into modern, contemporary office space located behind a retained facade that continues to blend into the urban surroundings. Crittall’s range of windows has allowed this to be achieved due to the trademark narrow slimline profiles, which allow more glass to be used in an aesthetic capacity without compromising the inherent strength and performance of the windows. Moreover, the unobtrusive appearance of the profiles allows the architectural value of the original structure to be clearly visible by all those who pass by in the City.

Crittall scoops Queen’s Award

Britain's leading steel window manufacturer has received the prestigious Queen's Award for Enterprise in International Trade.

Crittall Windows has received the award in recognition of its export achievements in the notoriously difficult American market where the Essex-based company has seen the value of its sales increase significantly over recent years. Crittall is now the second largest supplier of steel windows in the United States having re-built its entire distribution network there in just six years.

"We feel proud and honoured to be recognised by the queen's Award for our work and success in the US market, " said John Pyatt. "America can be seen as one of the hardest markets to compete in, and this accolade is the culmination of Crittall's long history, showing how a professionally-managed private company with an excellent product, a strong brand, and an enthusiastic workforce can take on the Americans at their own game."

The company dates back to 1849, and in 2004 Crittall Windows underwent a management buyout led by Mr Pyatt. At this point, its distribution market in the States disappeared, and the company had to begin again from scratch with its US operation.

Then, three years later, Crittall Windows moved to new state-of-the-art premises in Witham Essex from its factory in Braintree. Despite the upheaval, and now, the recession, the company has gone from strength to strength.

On both sides of the Atlantic, its products are being specified in high quality public and private sector buildings. These include the US 'Ivy League' universities of Princeton and Yale, the prestigious 300 Central Park West apartment block in New York, the University of Sussex, Grade II Listed Lichfield Court flats in Richmond-Upon-Thames, and the restored Royal Shakespeare Theatre in Stratford-Upon-Avon. The firm is especially strong in the heritage market in both countries.

In order to win a Queen's Award, companies also have to demonstrate high quality business practices in employe relations, environmental policy, health and safety matters, and its relationship with the local community. In all these matters, Crittall Windows has scored very highly. Its worforce of around 200 is drawn from the local area, and one in ten employees has been with the firm more than 40 years.

"This is, in effect, an award for excellence in how we have gone about our business," says Managing Director John Pyatt.

Steel Windows - Repair or Replace

Windows are that part of a building's fabric that so often defines the character and aesthetic of the property.

In many early-to-mid 20th Century buildings, across both public and private sectors, those windows are made of ungalvanised steel, and the passage of years may have taken its toll, in terms of corrosion, failing paintwork, broken or bent hardware. The glass and glazing compound may also have suffered.

Faced with ever more stringent Building Regulations, the owners of such properties need to decide how to proceed with improvements. They can be reassured that excellent opportunities exist for either improving the condition of what is already there, or replacing them with modern equivalents.

Crittall is the UK market leader, with 150 years' experience in steel fenestration, and has a long history of involvement in repair and replacement of windows, working closely with local authority planning and conservation officers, with architects, and with conservation bodies, such as English Heritage, to repair or replace windows installed from the early 1900s. Over 70 percent of the company's UK work falls into this category, with Crittall providing a survey, design, manufacture and installation service, acting, in many cases, as main contractor.

The decision to repair or replace depends on many factors, not least, the amount of maintenance that has been undertaken on a property. Before 1947, steel windows were only zinc sprayed, rather than hot-dip galvanised as they are today. So, pre-war fenestration may be deeply corroded.

Successive layers of paintwork, bowed or misaligned sections, missing putty, and broken handles or stays are also likely to be factors.

Repair work can be of a limited nature, performed on-site to tackle light corrosion, remove minor frame distortions, and re-glaze, with perhaps the addition of draught-proof gaskets and secondary glazing. Costs can be relatively modest, but, of course, the improved windows will not conform to modern performance requirements, especially in respect of energy efficiency.

An alternative approach is to remove the units, and return them to the factory for total refurbishment, where the frames are grit-blasted back to the bare metal, damaged units repaired, with new sections welded-in, hot-dip galvanising takes place, and the frame is polyester powder-coated providing 15-20 years' protection before any further painting is required. Draught-proofing and secondary glazing can be added, and new hardware fitted to match the original.

All this can be costly, and the windows will still not meet modern performance standards.

However, both the current, and forthcoming amendments to the Building Regulations Part L on energy efficiency make allowances for buildings of historical or architectural merit, covering a wide range of properties, either as individual structures, or within the context of their neighbourhood. So, this level of repair, may be adequate to satisfy the requirement of Part L.

The aim, however, should be, both to preserve, and to achieve betterment wherever possible.

The answer is replacement steel windows which may be deemed a more economic solution, in view of the findings of a condition survey, and a desire to achieve modern performance standards.

New steel fenestration will allow for double glazing that meets either a 2.2 W/m² whole window U-value, or a centre-pane U-value of 1.2 W/m²k. This will contribute towards the new requirements for reducing a building's carbon emissions total, as spelled out in the revised Part L. Weatherstripping, trickle ventilation, corrosion protection, and polyester powder coating are also part of the solution, while at the same time, replicating the visual effect of the original windows.

Examples of this abound. Look at the new facade of the Boots Company's D10 Building in Nottingham. This is a Grade I listed building dating from 1932.

Working with the original firm of architects, and, in consulatation with English Heritage, Crittall supplied and installed its Corporate W20 windows to recreate the curtain-walling effect for which this exceptional modern movement structure is famous.

Social housing refurbishments include the high-rise Avondale Tower for the Corporation of London, and Northwood House for Lambeth LBC. Then there is the neo-gothic Crown Court building at Wood Green in North London, the celebrated Hoover Building alongside the A40 in West London, and the Grade II listed Viceroy Court, a private residential block with curved fenestration overlooking Regents Park.

Crittall's current range of windows provides modern, high-performance replacements for the Universal range first seen in 1909, and the imperial SMW introduced in the 1920s. The original fenestra joint, patented in 1905, is still available. Bespoke solutions can be created as required.

Experience shows that each project must be reviewed on its own merits, and that repair, where possible, is the first option, and is preferred for aesthetic reasons. If, however, replacement is chosen, to meet cost, or performance requirements, then this can be done sympathetically, with modern steel products, that satisfy the regs and aesthetic appeal of a project in equal measure.

New York Botanical Gardens

Crittall Windows has been involved in a multi-million dollar project at the New York Botanical Garden. The Garden occupies 250 acres of land in the heart of New York, and a major expansion of the facilities is underway. The new Leon Levy Visitor Center is one of the most dramatic additions. It comprises four separate structures forming an elegant and functional transition from the urban sophistication of the cityscape to the pastoral environment of the Garden.

Designed by the architect, Hugh Hardy, founding principal of H3 Hardy Collaboration Architecture, with Gabriel Hernandez, project architect and project designer, the Center was opened in May 2004, and occupies a three-and-a-half acre site at the main Conservatory Gate entrances. Steel stone and glass enhance the architectural style of the building, which consolidates the Garden’s existing visitor service, whilst expanding its amenities. The Center includes a Shop in the Garden, with both indoor and outdoor components, a new café, an outdoor plaza and a visitor orientation area.

The Center is surrounded by a U-shaped formation of hills and trees.

The buildings are constructed of dark Hamilton bluestone, supplemented with wood, steel and glass. Crittall supplied its Corporate 2000 profiles to meet the architect’s specification, as well as cold-formed doors. The Corporate 2000 range offers the dual benefits of strength and aesthetic appeal, with the appearance of the profiles minimizing the intrusion of mullions and transoms without detracting from the original, traditional; appearance of the surrounding architecture. This emphasis on transparency is a key and prominent feature in the building’s external appearance, with large sections of the buildings enclosed in glass, framing views of the surrounding landscape, and its canopy of conifers.
“The crisp profiles and simple joinery of the Botanical Garden’s steel windows add immeasurably to the pavilions’ generous views of the rolling landscape,” says Hugh Hardy of the architectural practice.

The Leon Levy Visitor Center is part of a $200 million master plan for capital improvements to the 112 year old garden, which began in 1997 with the opening of the Enid A Haupt Conservatory, the country’s largest Victorian-style glasshouse. Subsequent phases include the Nolen Glasshouse for Living Collections, which will be the largest behind-the-scenes glasshouse for growing plants at any botanical garden in the USA.

Soho Hotel, London

"Style savvy" is the description of the fashionable new Soho Hotel in London, located in the centre of Soho between Wardour and Dean Streets. The hotel, part of the Firmdale Hotel chain was formally opened in September 2004 and Crittall supplied all the windows to the structure from its Corporate W20 range.

In all, 159 windows were specified by the architect, Peter French, with small panes and curved heads. In addition the front entrance doors were designed from Corporate W20 profiles to match the fenestration. The Corporate W20 profile offers flexibility in design via shaped windows, and has the ability to form extensive composite windows. Aesthetically, it delivers very slim sightlines, thus maximising the glazing, which, in the case of the Soho Hotel, is a major feature of the design.

Steel was chosen to meet with planning requirements and to complement the surrounding buildings in the area. The use of glass as a design medium in its own right, complementing the style of construction. The style of the structure demanded elegant fenestration and slim profiles for the window details, and Crittall supplied its products for the purpose.
The new hotel offers 85 bedrooms and 6 private apartments, and is contemporary both internally and externally. The use of Crittall fenestration for the doors and windows adds a uniform visual appeal to the new hotel.

St Pauls School, Concord, New Hampshire

St Pauls School, founded in 1856 is an independent, co-educational, fully residential boarding school in Concord, New Hampshire.

In June 1996 the school awarded a two-summer dormitories addition/renovation project consisting of additions and renovations to the four, nearly identical, dormitory buildings known as the Quads. The scope of work for each of the four buildings consisted of a 3,000 sq ft faculty apartment addition, plus a gut renovation of the existing 12,000 sq ft building.

The addition, which was architecturally designed to match the original 1927 design incorporated brick, limestone, ornate copper flashings, and lead-camed steel windows. Crittall Windows supplied hundreds of hot-dip galvanized Homelight casement windows with lead camed IGU's to match the original 1927 style.
