Kawneer

CREATING A FLUSH FINISH WITH KAWNEER’S   ENHANCED CURTAIN WALL SYSTEMS 

With ever-increasing market demands for more robust and flexible façade systems, Kawneer, the leading manufacturer of architectural aluminium glazing systems has launched a new version of its successful AA®100 and AA®110 curtain wall products. In addition to a +/- 5mm building expansion joint for its SSG curtain wall variant and a higher weight capacity for its capped option, one of the key enhancements is a concealed vent option within the product to help produce a beautiful, finished aesthetic to a building’s façade. Designed specifically for the AA®100 and AA®110 systems in either capped or SSG variants, the concealed vent option utilises a structurally bonded glazed unit and slim aluminium profiles, allowing Kawneer curtain wall systems to be installed with no visible external framing. This provides designers, specifiers and architects with the flexibility and freedom to create a flush finish to the external facade, while satisfying ventilation requirements for optimised comfort.   Contemporary building façade design also requires larger glass panes, with unobstructed views and increased natural light. The new enhancements result in the AA®110 being able to accommodate glazing up to a 50mm depth in the capped system and withstand a maximum weight capacity of 180kg. Available as a top hung vent or a parallel opening window, both types can be manually operated or motorised, using neatly concealed chain drives and integrated locking drives to achieve a seamless internal finish.      The AA®110 concealed vent has undergone full CWCT Sequence B testing as part of a larger curtain wall assembly, with proven weather performance. Furthermore, the window has been RC2 security tested to EN 1627, which is the same classification as the existing AA®100 and AA®110 curtain wall systems.   As with the AA®100 system, the AA®110 offers a range of construction methods, including zone-drainage and mullion-drainage. Also, advanced thermal break technologies provide superior thermal performance that meet and exceed building regulations.   Kawneer’s Technical Director, Gary Ledger commented: “Together with our new +/- 5mm SSG expansion joint and increased weight capacity, the concealed vent option subsequently gives architects ultimate design freedom with our enhanced AA®110 curtain wall product by combining exceptional product performance with visual aesthetics and occupancy comfort.”

Kawneer launches market-leading building movement feature

Kawneer introduces an enhanced +/- 5mm expansion joint to its high-performance AA®110 SSG system.  One of the main complexities in designing a glazed 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 glazed 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 a new expansion joint by Kawneer.  This new development has now enabled Kawneer to offer an expansion joint for its AA®110 SSG system that can withstand a +/- 5mm amount of movement tolerance.  The recent launch of the capped variation of the expansion joint for Kawneer’s AA®110 curtain wall system, which allows a +/- 15mm building tolerance, has now been successfully followed by the SSG (Structurally Silicone Sealed) variant.  While a conventional SSG system would be limited in its movement capabilities due to the hidden clamping nature of the glass and toggle engagement requirements, the new Kawneer solution has re-designed glass clamping rails and a re-designed toggle system to allow for greater slab deflection and differential movement.  The addition of the SSG expansion joint allows increased flexibility in architectural specification where the clean lines of a silicone glazed façade are desired, but without compromising the requirement for reduced slab sizes and cost.    The new 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.   To ensure compliance with UK standards, the new enhancement has been rigorously tested during development to ensure high 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 new +/- 5mm SSG expansion joint was in its compression, extension and neutral positions.  Alongside the new expansion joint enhancement, Kawneer has also increased the glazing weight capacity of the AA®110 system which will bring it in line with the current AA®100 system, providing glass weight capability of up to 600kg. The introduction of a 36mm thermal break provides enhanced thermal performance and increased glass thickness capability up to 50mm.  Kawneer’s Technical Director Gary Ledger commented: “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 enough allowance for in-service building movement can range from a reduction in weather performance to glass breakage and significant system failure.   “Our new +/- 5mm SSG expansion joint is a welcome addition to our AA®110 product offer and follows on from the popular capped expansion joint launched in 2019. This subsequently gives architects ultimate design freedom by providing a traditional stick curtain wall system that gives exceptional performance and tolerance of building movement.”

Kawneer systems help take the wind out of Birmingham’s sails

Curtain walling, windows and doors feature on a 33-storey apartment tower. High performance building façade products manufactured by leading UK manufacturer Kawneer were specified to handle the challenging wind loads on Birmingham’s tallest exclusively residential tower block. Kawneer’s AA®100 zone-drained and capped curtain walling, complemented by AA®720 top-hung ventilator windows on the first to top floors, with AA®190 TB entrance doors on the ground floor, were specified by Glancy Nicholls Architects for the £30 million 33-storey Left Bank 2 tower. The external façade is constructed of in-situ reinforced concrete frames that were developed over two years by main contractor Wates for developer Regal Property Group, Left Bank 2 is the second tower to feature Kawneer’s aluminium systems at The Bank, between Broad Street and Brindley Place in the city centre. Also funded by real estate investment company Aprirose, Left Bank 2 comprises 217 luxury one to three-bedroomed apartments with private gym, residents lounge and coffee bar, private kitchen and dining room, on-site cycle storage, and secure and private outdoor green space. Featuring 3,580ft2 of ground-floor retail space, it is one of only two residential skyscrapers in the city to measure over 100 metres tall. Left Bank 1 is 21 storeys and features Kawneer’s thermally superior AA®720 windows. Glancy Nicholls’ focus was to respond to the Grade ll listed building that occupies a key part of both the site and its streetscape, and to provide a new public realm link to the adjacent commercial and leisure district. The “brass” building envelope on both towers takes reference from the historical context of the neighbouring Brasshouse building and the site’s brass and metal working heritage. Glancy Nicholls’ Marketing Co-ordinator Sophie Casewell said: “We specified the Kawneer systems for their system performance, particularly in relation to wind loads. “The curtain wall system delivered the required performance to deal with the challenging wind loads on the 33-storey tower, with the site also elevated geographically within Birmingham. The aesthetics of the system also delivered upon the desired design intent.” She added: “The Kawneer glazed elements are a significant element with the façade design and assisted with the aesthetic detailing required. The glass to glass corners maximise daylighting and views across the city. “The client has been very satisfied with the product, with over 70% of the apartments sold by building completion. The glass to glass corner windows were a big selling point and the aluminium material assisted in achieving the client’s sustainable target deliverables.” The Kawneer systems, including AA®100 curtain walling featuring 50mm sightlines, were installed over 18 months by a team of eight operatives from Kawneer-approved specialist sub-contractor APiC UK who also installed the Kawneer windows on Left Bank 1. APiC’s Sales and Estimating Technician Andrew Finn said: “The relationship that was established on the first tower ensured that Wates and Glancy Nicholls had the confidence to proceed on Left Bank 2 using Kawneer products with APiC as their preferred curtain walling sub-contractor.” Left Bank 2 was a finalist in the 2020 Facades Awards UK for Best use of a building facade system using aluminium. Glancy Nicholls have also used Kawneer systems on the St Modwen student residences in Swansea and the John Taylor Free School in Burton.

Kawneer curtain walling holds a unique key to a gateway building

Fritted glazing is the star at Manchester’s Citylabs 2.0. Two types of curtain walling by leading UK manufacturer Kawneer met a quartet of criteria for a new building at the gateway to Europe’s largest clinical-academic campus. Kawneer’s AA®110 SSG (Structurally Silicone Glazed) and AA®100 capped aluminium curtain walling almost completely wraps the new £25 million Citylabs 2.0 development within the Oxford Road Corridor innovation district in Manchester. Citylabs 2.0 is part of a £95 million expansion to the Citylabs campus which is located at Manchester University NHS Foundation Trust’s (MFT) Oxford Road hub and is a partnership between MFT and the UK’s leading property provider to the science and tech sector, Bruntwood SciTech.                                                                                                                  The project builds on the success of Citylabs 1.0 which opened in 2014 and is fully-let, and Citylabs 2.0 will provide world-class lab and office space for global diagnostics company QIAGEN who have 100% pre-let the building for their Global Centre of Excellence for Precision Medicine. Kawneer’s AA®110 SSG curtain walling with flush silicone sightlines has been used throughout, while the AA®100 version with 50mm sightlines features on the ground floor entrance of the 8,500m2 state-of-the-art building designed by frequent Kawneer specifiers, architects Sheppard Robson. The practice conceived Citylabs 2.0 as a block of accommodation with one elevational treatment, with recessed areas carved out of the main block clad in alternative materials. To realise this concept, the main body was formed in the Kawneer AA®110 flush cap-less curtain walling, with a digitally printed design to the glazing. The concrete frame of the building provides clear open floor plates to support different work typologies while the post-pensioned floor slabs provide clear, uninterrupted soffits for ease of services distribution. The recesses at level 5 and the plant room are clad in ribbed fibre cement panels, the recess on the Hathersage Road elevation is clad in louvres, and the recess to the main entrance is the Kawneer full-height AA®100 curtain walling with accentuated vertical caps. The set back edges, and entrance canopy soffit, are clad in a bright coloured red anodized metal panel. Sheppard Robson associate Mary-Ann Crompton said: “The sub-contractor chose Kawneer as the best product to realise the design intent and it achieved the required performance specification in terms of aesthetics, thermal, acoustic and movement requirements.” The AA®110 SSG curtain walling, with its wider 65mm back box, is typically specified to minimise building movement and at Citylabs 2.0 was complemented by the fritted glazing and spandrel panels. “The existing adjacent buildings are Grade 2 listed and the cutbacks to Citylabs 2.0 have been organised to respond to the location and scale of them. The etched design to the glazing refers to details within the retained chapel which is to be refurbished as part of further future developments for Citylabs 3.0,” said Mary-Ann. She added: “The glazed elements of the curtain walling form the major component of the elevational design and has helped to fulfil the aesthetic aspirations for the project. In addition, aluminium is totally recyclable and is therefore a good material to use. This characteristic helps towards achieving a sustainable design.” The Kawneer systems were installed for main contractor Sir Robert McAlpine over six months by teams of up to eight people from Kawneer-approved specialist sub-contractor and dealer Bennett Architectural Aluminium Solutions. Director Rob Bennett said: “The project was fully enclosed in Kawneer curtain wall. It was a large project for us and had to be installed within 25 weeks. The AA®110 curtain walling allowed increased building movement capability. “The glass on it was quite unique. We worked with the architect and designed a frit pattern that was used as part of solar control. It has a very unique whirl and is quite striking.” Mary-Ann said: “We have used Kawneer on many of our projects over the years and have found that the technical and sales departments are very helpful with providing information at the early stages of design.” Businesses which locate to Citylabs have direct access to MFT’s specialist clinical resources and expertise from researchers, clinicians and procurement teams as well as Bruntwood SciTech’s specialist growth support and events programme, including access to funding, talent, new markets and academic connections.

Kawneer products selected for £50 million award-winning Crown Place redevelopment

High-performance curtain wall and door products feature on the refurbished ‘commercial to premium student accommodation’ development. Architectural glazing systems developed and supplied by leading UK manufacturer Kawneer successfully met a trio of criteria for the £50 million award-winning redevelopment of two existing commercial office blocks into premium student accommodation. A large part of the façade at Crown Place, formerly St Stephens Towers, in Norwich, features Kawneer’s AA®100 curtain wall system with 50mm sightlines and AA®720 top-hung glazed-in and AA®720 standalone windows. Two types of Kawneer commercial entrance doors also feature – the thermally superior AA®720 and the heavy-duty 190 series – to meet the required thermal, acoustic and aesthetic performance. The two eight-storey towers now feature an additional floor and a new link building between them, providing 705 premium student accommodation units including “twodios” (for two people sharing a kitchenette) above live retail units. Main contractor RG Carter Ltd initially built the office blocks in the early 1970s and they returned to refurbish them to ease the high demand for purpose-built student accommodation in Norwich city centre. Crown Place also features high-specification communal spaces including games rooms, cinema, gym, roof terrace and café. The entire building was re-clad in Kawneer’s AA®100 curtain wall system, fabricated and installed by a team of six from approved specialist sub-contractor and Kawneer dealer Drayton Windows on a logistically challenging site next to a high-traffic city centre location and above busy occupied retail units. Architects ECE Westworks were appointed by client Crown Student Living to transform the prominent and unoccupied towers and ancillary buildings into a justified gateway building that provides part of a major investment and regeneration to the local area. As well as the addition of a new storey to each tower, their design incorporated additional storeys to the existing wings of the steel-frame building and two new atria opened up, down to the level of the double basement which comprises a large part of the 0.476 hectare site. ECE Westworks associate Andy Bremerkamp said the Kawneer systems had been chosen by RG Carter Ltd and approved by the client and the practice which has used them on previous office and residential projects. “They met the required thermal, acoustic and aesthetic performance for a variety of curtain wall sizes and have been used to articulate the façade as a response to the large monolithic existing building form,” he said. “The curtain walling interfaces with the metal cladding, with powder coated metal reveals. It was important to make the building of this scale as sustainable as possible. The client is very happy with the finished building.” Crown Place, Norwich won ECE Westworks a RICS Social Impact Award 2020 and a shortlisting in the Student Accommodation Conference and Awards 2019 as well as RG Carter Ltd a gold award in the 2020 Considerate Constructors Scheme.

Bespoke curtain walling by Kawneer helps ground a landmark office building

Three types of Kawneer’s curtain wall feature on the Atlas’ commercial element. Bespoke curtain walling by leading UK manufacturer Kawneer was preferred for an 11-storey office building at the heart of London’s architectural sector. Kawneer’s AA®265 unitised system was adapted by the company for the commercial element of the £200 million Atlas building – at 40 storeys the tallest tower in London’s Tech City area – at 145 City Road, Clerkenwell. Concept-designed by Make architects and delivered by the Design Delivery Unit of Scott Brownrigg, the commercial building actually featured a total of three types of Kawneer’s curtain walling – the traditional stick system AA®110 (zone drained) on the ground floor, the adapted AA®265 on the floors above, and standard unitised AA®201 on the tenth floor return elevation to the existing building. The adapted AA®265 modular system incorporated GRC and aluminium rainscreen cladding and glazed vision areas in each panel. Some 3m wide, 3.85m high and one tonne in weight, each unit was delivered to site and hoisted into position by a tower crane, complete with the cladding and glazing in place. Kawneer’s Technical Proposals Engineer Dave Fletcher said: “The basic AA®265 design was revised to accommodate the building movement that had been identified by the structural engineers as it could accommodate the size of units and the GRC rainscreen units being pre-fixed to the panels. “The system developments, including new profile and accessory design such as 19 project-specific dies, were all carried out by our Technical Department at our Head Office.” Installed by specialist sub-contractor Mace Facades for main contractor Mace, the Kawneer systems also included thermally superior AA®720 entrance doors on all floors. The Atlas’ commercial element is occupied by WeWork and features a strong emphasis on nature, with three roof terraces and external green walls. WeWorks’ coworking space allows members to enjoy 11 floors of collaborative work spaces, stunning private offices, welcoming event spaces, and modern conference rooms for hosting key client meetings. In addition to being dog-friendly, this super-accommodating office space features bike storage and on-site showers. Along with the Atlas tower, the WeWork building sits above the London Underground and Thameslink lines. This discovery at planning stage changed the concept for the structural strategy, resulting in the creation of a new superstructure design to prevent the buildings from twisting and leaning. Loads imposed by the buildings are kept clear of the tube tunnels by cantilevering the structures over the subterranean Victorian engineering. The mass provided by the frame, and by increasing the thickness of the ground-floor and mezzanine first-floor slabs, helped give the structure sufficient inertia to dampen the ground-borne vibration from the underground trains. The original planning concept was for a series of white and off-white shades of terracotta cladding. However, with the stability issues raised at post-planning, the weight of the terracotta posed a challenge with the cantilevered building. Design Delivery Unit at Scott Brownrigg demonstrated options that could be achieved using anodised aluminium, and following modelling and testing of the material, proved that given the scale, repetition and shape of the facade, a unitised system would work and still achieve the original vision.

Kawneer systems help herald a gateway to a unique building

Manufacturer’s aluminium glazing systems used again at Bournemouth University. Frequent Kawneer specifiers Atkins has used the manufacturer’s architectural aluminium glazing systems again, on a unique building which forms a new £27 million gateway to a leading UK university. Kawneer’s AA®100 zone-drained and capped curtain walling forms triangular screens some 25m wide and 15m high for the main atrium at Bournemouth University’s 5,000m2 Poole Gateway Building, while Kawneer’s thermally-superior AA®720 entrance doors were used throughout the building and its AA®190 TB automatic sliding door was used at the campus side entrance lobby. In addition, Kawneer’s AA®541 fixed-light windows were used to create openings within both the rainscreen and masonry facades while thermally-broken AA®543 tilturn windows were used alongside aluminium spandrel panels as insertions to the curtain walling. Kirsty Pesticcio, senior architect at Atkins, said: “The glazed elements have a significant impact on the building and the Kawneer products interfaced really well with the masonry and rainscreen façade. “The triangulated gateway form was very complex in nature so we had to ensure fixings were angled with precision to tie into the structural members. Kawneer-approved installer Leay were engaged early within the design process to ensure the developing design met both our design concept and technical constraints of the products chosen.” The building was targeting a BREEAM “Excellent” score so upper BRE Green Guide ratings for material specification, aligned with budgets, was important. The Poole Gateway building is a state-of-the-art combined technical facility for the university’s faculties of Science and Technology and Media and Communication, the latter of which houses the UK’s only recognised Centre for Excellence in Media Practice. The two-year build by main contractor Willmott Dixon comprises a steel frame, SFS infill and composite concrete decked floors. Although the building is primarily divided by internal stud partitions, there are many technical studio spaces which had to be designed and installed as a ‘room in room’ construction using timber frames. Specialist sub-contractor Leay had a team of up to six on site for three winter months. Leay’s business development manager Mike Watts said: “The main curtain wall screens are essentially large triangles. The transom locations were staggered in design in an attempt to prevent hard lines being established in the overall design. “The transoms were set out by us to keep glass specification the same thickness on the project and also to optimise the material on the project efficiently to keep wastage down and therefore cost. “The project was also designed to limit the amount of intermediate steelwork to make the atrium feel as open plan as possible as well as to dead load the full screen down onto the ground-floor slab. “We proposed the use of Kawneer products on this scheme from the outset as we knew they would represent the best value for money and also achieve the structural requirements of the scheme. Working alongside the architect from an early stage, we were able to quickly assist with mullion sizings to allow setting out to be established and avoid potential clashes at a very early stage.” Atkins’ brief was to deliver a new gateway building on the eastern edge of the university’s Talbot Campus which sits just inside the border between Bournemouth and Poole and would be predominantly used by students from the two faculties, providing a range of high-quality technical facilities to support undergraduate and postgraduate courses as well as research. Kirsty Pesticcio said: “We believe the client is delighted with the overall design and how it meets the original brief of a gateway building to their campus.” NESTA (National Endowment for Science Technology and Art) said: “Almost half of all graduates from specialist VFX [visual effects] courses who gained employment in the industry had graduated from Bournemouth University”. Graduates have worked on Hollywood blockbusters such as Lord of the Rings, Gladiator, Gravity, Star Wars, Madagascar and Interstellar, which won an Oscar in 2015. The Poole Gateway building is one of three at Bournemouth University which feature Kawneer systems. They have also been used on a £40 million new home for the Faculty of Health and Social Sciences. Again designed by Atkins, the Bournemouth Gateway Building features Kawneer’s AA®100 curtain walling with feature face caps on tall atrium screens along with AA®720 window vents and entrance doors and AA®190 TB doors. The Kawneer systems here were installed by fellow Kawneer-approved dealer Aluminium Sashes for main contractor Kier. The Bournemouth Gateway Building is due to open in September 2020. Kawneer systems were also used on the original £22 million BREEAM “Excellent” Fusion building which features Kawneer’s AA®100 zone-drained curtain walling, AA®541 top-hung casement windows, AA®545 low/medium duty swing doors and series 190 doors. These were installed by approved dealer AB Glass for Willmott Dixon to a BDP design.

Kawneer helps Wales get creative

Aluminium glazing systems by Kawneer feature at Welsh University’s new creative and digital centre. Architectural glazing systems by leading UK manufacturer Kawneer played a key role in a new state-of-the-art building which is at the heart of Wales’ creative and digital future. Kawneer’s AA®110 curtain walling, AA®720 doors and window vents, and series 190 doors feature on the £10 million new creative and digital centre, Canolfan S4C Yr Egin, located on the University of Wales Trinity Saint David’s (UWTSD) Carmarthen campus. Specified by BDP architects, they were installed over 10 months by a team of up to eight from Kawneer-approved dealer APiC UK for main contractor Kier Construction. The AA®110 zone-drained curtain walling with 65mm sightlines was used alongside Kawneer’s thermally superior AA®720 doors and series 190 automatic entrance doors on the ground floor which houses a spacious public café alongside performance space and auditorium as well as resources for community groups and offices for the building’s administrative staff. The AA®110 system also features on the first floor, which is let to the centre’s main anchor tenant – Welsh language broadcaster S4C – for its headquarters (corporate, communications, finance, business affairs and legal departments) alongside actuator-operated AA®720 top-hung, open-out window vents. And it also features on the third floor, which is let to a number of different companies working in the creative and digital sector, as well as on a clerestory lantern above an atrium which overarches the three storeys. Many of these tenants will offer work experience to UWTSD students, allowing them to make the most of the university’s connections during their studies. BDP’s award-winning design was based on the close relationship between the university, prospective tenants of the centre and the wider community. This relationship, or trinity, is reflected in its form – a simple triangle that grows from Carmarthenshire’s soil, a titular reference to Yr Egin – a Welsh play on words referencing energy and birth. The layout of the building encourages collaboration, communication and interaction between all users of the building, where initial ideas can be shared and developed – an incubator for the establishment of new companies and a breeding ground for a new generation of creative and technical people. Externally, the theme of trinity is expressed through the use of differing materials in a tripartite arrangement – a dynamic, reflective volume is seen to float over a solid plinth at ground level and a translucent intermediate layer reinforces the distinction between plinth and reflective object. The 3,600m2 building is linked to the main campus by a large public square which allows for the staging of a variety of outdoor activities in its stunning Carmarthenshire location between the Pembrokeshire coast and the Brecon Beacons. On the use of Kawneer’s systems, BDP’s project architect noted: “As most of the façade comprises curtain wall we needed a system that could meet a wide range of performance requirements. We specified Kawneer due to their extensive range of features which met the functional and aesthetic demands of the project. “The Kawneer curtain walling had a key role in the project. As a naturally ventilated building it has an active façade that reacts to changing environmental conditions. The Kawneer system houses the various components that protect the interior from the elements while allowing air to flow through. “A key element of the building’s aesthetic was to create a distinct character for each level of the building – a challenge for a facade almost entirely constructed from curtain wall. This challenge was met by the extensive range of Kawneer features, especially the fin capping, which was vital to the characterisation of the different elements of the facade.” The durability, strength to weight ratio and life cycle benefits of aluminium were key factors in the consideration of Kawneer’s system when specifying the external envelope. APiC UK senior sales and estimating technician Andrew Finn said: “Working with Kawneer we were able to offer solutions for all the differing project requirements including profiled vertical faced caps with new dies for the 100mm and 150mm profiles to the ground-floor curtain wall which was specified to accommodate the vertical movement of the building. “The 100mm, 150mm and 200mm vertical faced caps provide a strong vertical emphasis to the curtain wall. The use of differing sizes and finishes to these are designed to provide a ‘flickering effect”. Canolfan S4C Yr Egin was opened by the Rt Hon Carwyn Jones AM, first Minister of Wales, in October 2018 and has since won a RICS Wales award for best commercial building. RICS judges said the team behind the project – including Mott McDonald, BDP, Rural Office for Architecture, and the University of Wales Trinity St David – had succeeded in designing a scheme that encouraged occupiers to collaborate, network and exchange information and ideas, to innovate and create jobs.

Kawneer’s Systems All Feature at Bayscape

Leading UK manufacturer Kawneer had its full range of architectural glazing systems specified for a stunning residential development at Cardiff marina. The Kawneer systems were selected for Phase One of Bayscape Ltd’s £40 million mixed-use development, which has been shortlisted for an award. “We specified Kawneer because of the need for a high-quality and trusted product. Crisp detailing was important in the overall design concept and aluminium was essential for the marine environment,” said Andrew Baker, Director of Rio, award-winning architects who have used Kawneer systems on numerous projects. The two blocks of luxury apartments – Whitewater House and Waterford House – both used Kawneer’s AA®100 mullion-drained curtain walling with 50mm sightlines, thermally superior AA®720 tilturn and side-hung casement windows, and AA®545 open-out swing doors. Whitewater House, so named because it also overlooks Cardiff International White Water Centre, was first to complete, offering 56 generously-proportioned one, two and three- bedroom apartments including two penthouses. Meanwhile, Bayscape offers a total of 115 apartments, with optional private moorings, across seven and eight-storeys of apartments which are joined by an elevated garden podium. The ground floors feature a coffee shop, waterside bar and restaurant, commercial/retail units and marina management facility. The luxury apartments, which all feature private balconies or terraces, start at £175,000 and range from up to 624 ft2 for a one-bed, 990 ft2 for two bedrooms and 1,119 ft2 for a typical three-bedroom. Residents also benefit from undercroft parking, a concierge service and lift access to all floors. The impressive floor to ceiling double glazing in every apartment ensures they are light and airy and residents can enjoy the stunning views. The Kawneer systems were installed over five months by a team of up to eight operatives from approved dealer Dudley’s Aluminium for main contractor BECT Building Contractors. Dudley’s, which celebrates its 25th anniversary this year, also worked with Kawneer and BECT on another Cardiff project – One Canal Parade. Bayscape was shortlisted for residential development of the year in the 2018 Wales Insider Property Awards.

Kawneer’s Windows Help Design Pioneering Autism Centre

The windows supplied by the leading UK architectural glazing systems supplier, Kawneer, have helped meet a host of complex criteria for the UK’s first dedicated healthcare facility for adults with autism. The Mitford unit at Northgate Hospital in Morpeth, Northumberland, where fenestration was led by architectural glazing specialists Polar NE, uses a variety of Kawneer window and framing systems including a bespoke secure healthcare window specially fabricated for the £10 million project. This specialist window – based on the Kawneer AA®3110HW horizontal slider – has been used in the bedrooms and some communal areas alongside Kawneer’s AA®540 fixed casements in corridors, AA®541 top-hung casements in offices and reception, and 451PT framing in communal areas and corridors. Supplied in moss grey (RAL 7003), they were specified by Medical Architecture in conjunction with Kawneer dealer Polar who had a team of two specialist installers on site for 11 months. “Mental health inpatient windows are a very specialist product and we have developed designs with one of the few manufacturers/fabricators over a period of 11 years. Polar chose Kawneer’s AA®3110HW system components as a basis and we adapted the successful design to the particular needs of the autism unit,” said Medical Architecture director Paul Yeomans. The new BREEAM “Excellent” Mitford unit for Northumberland, Tyne and Wear NHS Foundation Trust provides 24-hour inpatient support and treatment for up to 15 adults with severely complex autistic spectrum disorders. Built by Kier under ProCure21+, the accommodation comprises eight single-person and two and three-person shared flats within four fingers of accommodation linked at their southern end by a band of shared spaces interspersed with staff facilities. Patients typically stay 18 months to two years, during which time individual stimuli and appropriate therapies are used before they return to the community. The trust’s key objectives included incorporating best practice from around the world and becoming a leading-edge national autism service, enhancing the facilities for research and development to provide a national centre of excellence, and building a sustainable commercial model to ensure the capital costs of the building were recuperated over an eight-year period.
