Zink CLADDING & SHEETING 01992 801927 www.almhm.co.uk VACGEN’S new, purpose-built UK headquarters in Hailsham, features a building envelope specification which includes both roof and wall systems from Kingspan Insulated Panels. Director of CRB Construction, Richard Burchett discusses the project: “As a company, we always aim to create buildings that are both attractive and functional. The Kingspan Insulated Panels systems offer the ideal balance between design freedom and unrivalled fabric performance. The combination of the two panel profiles, along with the glazed sections, provides a striking visual contrast. The industrial elegance of the building is further emphasised by the raised parapet, which conceals the pitched roofline and external services to create a sharp, clean external façade.” The building envelope was completed with a 3492m² KS1000RW Trapezoidal Roof. According to Kingspan, the 115mm thick through-fix trapezoidal roof panels can deliver U-values as low as 0.18 W/m²K and are suitable for building applications with roof pitches of 4° or more after deflection. To allow as much natural light as possible into the building, 414 m² of the Kingspan Day-Lite Trapezoidal rooflights of the same thickness were also integrated into the roof panel system. The translucent polycarbonate system provides resistance to UV degradation, resulting in long-term light transmission, structural performance and U-values of 1.6 W/m²K and 1.0 W/m²K, depending on the thickness. By using both roof and wall systems from Kingspan Insulated Panels, a potential overall air leakage rate of 3m³/hr/m² @ 50Pa or less can be achieved, therefore allowing energy use, carbon dioxide emissions and resulting costs to be reduced. www.kingspanpanels.co.uk 048 JULY 2017 RCIMAG.COM New choice for weatherboard Cembrit is entering the UK market with a brand-new fibre cement weatherboard – Cembrit Plank. Extremely versatile, low in maintenance, and rot, rust, warp, crack, sun, heat, rain and fire resistant, this board is said to be an excellent alternative to timber and plastic-based alternatives. The overlapping plank is designed to look like painted timber, but will retain its attractive appearance long after alternatives have started to age. Furthermore, Cembrit Plank does not require toxic preservative treatments in the way timber weatherboarding does. Cembrit Plank is warrantied for 15 years and there are 15 different colours available. A range of white and dark grey shades match traditional building styles, while the addition of reds, pale browns and pastel green offer a more contemporary choice. In addition, the range includes a ready primed option for clients wishing to add their own choice of colour. The range includes a comprehensive set of colour-matched accessories, including the roofline trims needed for a neat finish where façade meets the roof. Simon Mayes, Cembrit’s UK sales manager, said: “We have listened to our customers’ request for a wider range of colour options, dimensions and product properties. The reason why fibre cement products are gaining ground in the UK is its amazing sturdiness combined with minimum maintenance, which is particularly the case as a substitute for wood. I am confident that fibre cement weatherboard is the ‘timber cladding’ of the future.” www.cembrit.co.uk Proteus HR cladding in elZinc Rainbow Gold has been used to create an eye-catching aesthetic on two new student residences at The University of East Anglia (UEA). LSI Architects set out to create a design for the two new student accommodation buildings that would relate directly to the original campus designed by visionary architect Denys Lasdun, as well as the local environment. Lasdun’s original 1960s Teaching Wall had a distinctive stepped appearance, created by each successive storey being set back from the one below. This iconic ‘ziggurat’ – a rectangular stepped tower – remains as striking as ever and provided the inspiration for the new student accommodation buildings that feature the Proteus cladding. The Proteus HR elZinc Rainbow Gold cladding panels gave LSI more design scope to replicate the most striking element of Lasdun’s creation – a modern interpretation of the stepped ziggurat design was created by projecting the accent cladding outwardly from the grey façade. Proteus HR is an integrated modular rainscreen cladding system that consists of an aluminium honeycomb core, structurally bonded between two thin gauges of metal skin. The lightweight yet strong panels are available in a wide range of colours and materials including steel, aluminium, zinc, stainless steel and copper alloys. The Proteus HR elZinc Rainbow Gold panels were made from rolled titanium zinc, which forms an attractive and durable finish. The elZinc Rainbow range is available from Proteus in a range of graded colours. James Lake, architect at LSI, said: “Proteus HR accent cladding in elZinc Rainbow Gold delivered an aesthetic that lifts the whole development in a similar way to Lasdun’s striking stepped ziggurat. “The elZinc provides a beautiful contrast to the other façade materials and has the effect of transforming the whole aesthetic. It complements Lasdun’s original design, whilst the iridescence gold finish gives a nod to modernity.” Having a honeycomb core means that the Proteus HR panels deliver maximum compression and shear resistance with minimal material. This helped the development at UEA minimise the load transferred to the main structure, significantly reducing overall material requirements compared to the original concrete structure. The project achieves a BREEAM Excellent rating and both new buildings have been delivered to BIM Level 2 including the delivery of an Asset Information Model. www.proteusfacades.com University of East Anglia takes gold with Proteus HR cladding Copper Stainless New HQ takes flight
