Kawneer glazing systems are an Academy winner
Kawneer glazing systems are an Academy winner
Windows, curtain walling and doors feature on the new London Screen Academy.
Architectural glazing systems by leading UK manufacturer Kawneer, including aluminium heritage-style windows appropriate for the conservation area, have helped to transform the façade of an old radio and television factory into the new London Screen Academy.
Kawneer's GT70S slimline renovation open-in windows were the "focal new element" of the renovation of the façade of the four-storey building at Highbury Grove in Islington, north London, where Kawneer's AA®100 zone-drained curtain walling and series AA®190 TB entrance doors also feature.
The GT70S windows with narrow sightlines were installed over 12 weeks by a team of eight from specialist sub-contractor and Kawneer dealer JPJ Installations throughout the 8,050m2 building, with the AA®100 curtain walling, which also has narrow 50mm sightlines, used on the rear elevation and the series AA®190 TB severe-duty welded doors used on the main entrance.
This cutting-edge new free school by the Department for Education provides world-class film industry focused vocational training, including behind-the-camera roles, costume design, production management, distribution and marketing, alongside a broader curriculum, for 17 to 19-year-olds.
Procured through the Southern Construction Framework, main contractor Willmott Dixon Interiors worked closely with the design team from Architecture Initiative to deliver the project over 13 months, ready for the first intake of students in September 2019. Sponsored by Working Title Films, the end user is the Day One Trust.
The building, also formerly a London Metropolitan University facility, was subject to a dramatic internal reconfiguration, with the core of the deep-plan multi-storey industrial space demolished and replaced with a steel-framed three-storey film production studio and supporting facilities.
The general teaching and workshop spaces wrap around the centre core, responding to and utilising the existing external envelope which has remained largely unaltered in appearance. The insertion of a new rooftop courtyard with film theatre and extensive views over London completes the arrangement and provides informal social space for staff and students.
Architecture Initiative's brief was to design a creative education facility that would provide an inspirational learning environment alongside specialist technical facilities to train students in all aspects of digital and film technologies.
The practice's Lee Mainwaring said: "We combined the natural features of the existing building - large windows, generous floor-to-ceiling heights, exposed finishes - with state-of-the-art new technical training facilities based on extensive research and analysis of professional film studios, to create a unique building for students and the wider community.
"The building is in a conservation area so any works to the external façade were carefully considered. We also needed to work with current building regulations for schools to ensure we could provide a safe learning space but which also enabled us to make the most of the existing building and provide professional standard technical spaces.
"The local authority planners were really happy with the upgrades to the existing building façade which had been unsympathetically altered in previous times."
He added: "The external windows are the focal new element of the façade renovation. The Kawneer window system, which was offered by the contractor as a more cost-effective alternative, effectively met the technical requirements needed whilst achieving a 1930s warehouse "Crittall" window lookalike.
"The windows have greatly enhanced the existing façade as well as referring to the building's history with its design. The final product was of great quality and in keeping with the design concept."
He concluded: "The façade has been visually transformed, in part through the addition of the new windows that are perfectly in keeping with the heritage of the building. From a previously dilapidated appearance, the building has been rejuvenated. We are extremely happy with such an incredible looking product."
The creation of the London Screen Academy follows a recent report published by the British Film Institute which suggested the money spent on production in the UK reached a record level of £3.16 billion across all sectors including film, television and console games. Production investment in the UK has grown by 63% over the four years to 2016.
Kawneer Introduces an Enhanced Expansion Joint to accommodate Building Movement
Today’s requirement for building facades to incorporate increased levels of building movement has been met by Kawneer with the introduction of a curtain wall system with superior capabilities to counter slab deflection.
Kawneer has launched a fully CWCT tested version of its AA®110 curtain wall system with an expansion joint that will allow for up to 15mm of building movement.
While a conventional pressure-plated and face-capped stick system curtain wall can be constructed with allowance for movement in the vertical direction this is normally limited to +/- 2mm at a mullion/mullion joint. Kawneer have now developed a solution for the AA®110 curtain wall that will allow +/- 15mm at a mullion/mullion joint.
Conventional stick curtain walling is widely specified in the UK and offers a cost-effective façade solution, particularly on buildings which do not have a requirement for significant movement allowance.
One of the main complexities in designing a façade is the accommodation of slab movement/deflection and, due to the extension of structural spans seen in contemporary building designs, slab deflection is increasing. This places additional demands on a façade design team to accommodate movement between slab and façade.
When building designs require facades to withstand high slab deflections one solution is to incorporate unitised curtain wall systems like Kawneer’s AA®201 or AA®265 systems, which due to their construction, can provide greater movement allowance.
However, unitised curtain walling usually comes at a cost premium and is generally more appropriate for very large facades and where there might be issues of site access. Traditional stick curtain wall is more readily used by most fabricators and installers in the UK, hence the development of the expansion joint by Kawneer.
The standard mullion/mullion expansion joint only provides a +/- 2mm movement allowance. By increasing the deflection allowance in the curtain walling to +/- 15mm, the beams used to support floor slabs can be reduced in size and consequently in cost.
Working with our approved sub-contractor FK Group, the first project to feature our AA®110 expansion joint is Manchester’s prestigious Circle Square Development.
The joint locates at each slab level and is therefore concealed by spandrel glass or panels. Its specialised engineered foam seals expand and contract with the movement of the structure. A unique transom profile (which incorporates a concealed breather membrane) at each floor level provides allowance for the increased movement of the spandrel infill while maintaining the air and weather tightness of the façade.
Glazing and cladding systems need to be designed to allow for building movement without compromising the performance or safety of the system. The consequences of failing to provide sufficient allowance for in-service building movement can range from a reduction in weather performance to glass breakage and significant system failure.
In order to prove the system and to ensure compliance with UK standards, the expansion joint has been rigorously tested during development to ensure performance in all UK conditions. In consultation with the CWCT, an enhanced version of the Standard for Systemised Building Envelope: Sequence B programme was developed. This included a series of performance tests while the expansion joint was in compression, extension and in the neutral position.
Kawneer’s expansion joint gives architects ultimate design freedom by providing a traditional stick curtain wall system that gives exceptional performance in the area of building movement.
