CLADDING & SHEETING PROJECT FOCUS façade panels, which was particularly useful on this project as we had to plan the cladding works around the main contractor’s complex schedule. The flexibility offered by the Shackerley system meant that our team could return to complete areas and simply pick up where they had left off.” Complex requirements In addition to the Portland stonecoloured SureClad ceramic granite panels used to create the façades for the student union’s new elevations, the system was also specified for the capping details of the steps leading to the new entrance constructed as part of the new extension. Here, the SureClad system has been specified in a dark grey / black colourway to create a contrast with the creamy coloured façade and hard landscaping. Shackerley prefabricated the bespoke details required for the steps at its Lancashire production plant and delivered them to site for installation by entrance cladding installer, Churchmore. The project architect from Mason Wilson added: “The contrasting colour of ceramic granite not only creates impact at the new entrance to the building but also serves the practical purpose of highlighting the edge of the steps. “The fact that we could specify the same material for two very different applications from a single supplier demonstrates the flexibility of the material and the willingness of Shackerley to meet the demands of the project, even when there are complex design requirements involved.” Living room of the campus Construction of the new infill extensions has now been completed and the project to reshape the building as the ‘living room of the campus’ is ongoing, integrating the building as a cultural and education asset for the University and its current and future cohorts of students. A vital part of student life and the biggest student union in the UK, the University of Manchester’s student Union is set to create a new benchmark for student facilities on campus when all refurbishment and remodelling work completes in 2018. www.shackerley.com 034 JANUARY 2018 RCIMAG.COM Kalwall creates a flight of fancy Kalwall translucent cladding has been used in a project at Rayleigh Durham Airport in North Carolina designed by architects Clark Nexsen. The aging 1981 Terminal 1 building was nicknamed the ‘blue box’ as the original rectangular building was constructed using blue corrugated metal making it dark and uninviting while the inside was haphazard with a poor passenger flow. In a £50m scheme, a new terminal has emerged from a complete redesign with everything from the curbside to the interior space. On landside arrival, a Kalwall canopy system provides shelter and links access points while a Kalwall translucent façade is utilised to clad the main terminal building. Its ability to diffuse natural daylight Zink Copper Stainless into the interior means the new TSA screening facility now has complete privacy for the sensitive areas while bathing the interior with natural, glare-free light. Kalwall provides complete line-ofsight protection, maintaining privacy for building occupants while bathing the interior with diffused daylighting regardless of the weather. The system also enhances simplicity by doing away with the need for blinds, curtains or solar control. Kalwall is highly insulating which reduces energy costs. The standard Kalwall 70mm thick panel offers insulation up to 0.28W/m²K – equivalent to a cavity-filled solid wall. www.kalwall.com Building envelope contractor Longworth is working with SFS in the construction of two iconic towers in the heart of Birmingham: one clad in brass, the other silver. The proposals will deliver a mix of luxury apartments and retail spaces. The striking Left Bank development in the city centre’s popular West End will create the tallest exclusively residential building in Birmingham when it is completed in summer 2019. The first 22-storey building will accommodate 189 luxury apartments and 3,580m² ground floor retail space, with the second phase being a 31-storey residential tower with retail space too. The development is a prime location for residents as it's within easy walking distance of the major attractions and landmarks of central Birmingham. It will also offer amazing city views as well as the relaxing canals, bars, restaurants and shops that align Broad Street. Due to Birmingham's mix of modern and historic buildings, Glancy Nicholls Architects designed these two towers in response to the Grade II listed building, the adjacent Brasshouse building, and the industrial heritage of the site. Longworth was appointed by main contactor Wates Construction at an early stage and worked closely with them, alongside the architects, for over a year in the pre-construction phase of the project. This allowed for expert building envelope input during a period in which there were numerous specification changes and as well as the overall design for the first tower. The final choice of surface finishes for the envelope demanded high-quality fastening solutions that would stand the test of time and perfectly complement the crucial aesthetic goals. The partnership agreed on the supply and installation of an Alucoil Larson ACM FR - Brass Brushed panel with a fire-rated mineral core. This drained and back-ventilated rainscreen cladding system for Tower 1 was fitted with an Nvelope bracket and rail system and powdercoated SLA3 frame fasteners, SLA 5 fasteners, as well as SX3 and SX5 A4 (grade 316) stainless steel fasteners from SFS. Ben Parker, business development manager at Longworth, commented: "We're very proud to be appointed on the Left Bank development contract for cladding. We have brought a more creative project approach to provide a solution for an application that would usually be fixed with a rivet. Instead, we chose to use self-drilling fasteners from SFS for several key reasons. “Firstly, these fasteners enabled us to overcome the architect’s concerns regarding the colourmatch of the fixings to the ACM panels. We collaborated with SFS at an early stage to produce a number of fastener samples to get the closest match possible. Despite the challenge of the panel board’s marble effect which is said to shimmer in different light, the tenacity and determination of the SFS team to deliver the right powder coated fastener result was impressive, and on the sixth version we knew we’d achieved the perfect match. “We used the SLA5 fastener to help fix the panel to the frame as this fastener provided significant timesaving benefits over pre-drilling for rivets, and they offer a secure installation with prevention of overdriving and unwinding. SFS supported us by making several pull out tests on site to prove the fasteners’ effectiveness. We also used SX3 and SX5 fasteners in A4 (grade 316) stainless steel fasteners from SFS for their improved corrosion resistance.” Graeme McIlroy, SFS regional sales manager, commented: "It was a pleasure working with Longworth on this prestigious project. It’s a perfect demonstration of our powder coated fasteners capability which enables over 200 RAL colours. For this project, we were happy to go that extra mile to ensure a truly bespoke finish for our powder-coated fasteners and ensure the architects vision of the building could be fully realised. Tower 1 looks set to be a stunning building and I'm sure Tower 2, which will be clad in shades of silver, will make a striking contrast.” www.sfsintec.co.uk SFS fasteners chosen for Birmingham’s new tallest building 01992 801927 www.almhm.co.uk
