INSULATION The new University of Cambridge Sports Centre incorporates 4,500 m² of EWI RCIMAG.COM JULY 2014 049 Zink Copper Stainless A £50m restoration project to transform the Grade II listed Liverpool Central Library has achieved a BREEAM ‘Very Good’ rating with the help of Kingspan Insulation. The three-year restoration and redevelopment project at the UNESCO World Heritage site, in the heart of Liverpool’s cultural district, features more than 3,700m² of Kingspan Insulation Kooltherm K15 Rainscreen Board. The redevelopment of the library was carried out by Amber Infrastructure as part of the Inspire Partnership, a joint venture with Shepherd Construction. Available for both new build and refurbishment projects, the board holds LABC System Approval for use in rainscreen applications and features a highly insulated core delivering thermal conductivities as low as 0.020 W/m·K. In addition to its thermal performance, Kooltherm K15 Rainscreen Board can also contribute towards a number of other BREEAM credits, including Responsible Sourcing and Embodied Impact. The product has been assigned the Green Guide Summary Rating of A+ and is certified ‘Very Good’ under BES 6001: Responsible Sourcing of Construction Products standard. Maggie Mullan, spokesman for Austin-Smith: Lord, the architect involved in the project, said: “It was absolutely essential to specify the very best performing materials for the job and this included Kooltherm K15 Rainscreen Board which proved to be perfect for our requirements and the exactingly high quality required.” Kooltherm K15 Rainscreen Board is supported by Kingspan Insulation’s Technical Service Department which can provide specific U-Value calculations for the product’s use with a wide range of rainscreen systems. www.kingspaninsulation.co.uk High quality benefits The Liverpool Central Library Office project called for Blanket approach Spacetherm Blanket has been installed in an office construction, in Dundee, which consists of 37 recycled shipping containers. The first of ten buildings for ‘early stage’ creative companies in the heart of Seabraes Yard has 15 lettable office units spread over three floors. The building is constructed of 36 containers, with one turned on its end to form the entrance lobby to the complex. Each unit provides furnished space for up to four people. Spacetherm Blanket from the A. Proctor Group offered an insulation blanket solution with thermal conductivity of 0.015 W/mK to the project. Combining a silica aerogel with a fibre matrix, the company says it is a superior material suitable for a wide range of challenging applications where thermal performance is crucial. With the universal push towards zero carbon neighbourhoods and cities, District 10 provides an exemplar of mixed community planning while tackling the increasingly common issue of brownfield remediation. The intention is that Seabraes will become the centre of Dundee’s bustling creative industries. www.proctorgroup.com Sports centre EWI External Wall Insulation (EWI) by Saint-Gobain Weber has been specified for the new University of Cambridge Sports Centre, West Cambridge. The £16m phase-one project, designed by Arup Associates, provides a facility for hundreds of athletes from the University and local community, all under one roof. Network Weber-approved EWI specialist applicator M Clarke & Sons, Brentwood, Essex, was responsible for the installation of the award-winning, BBA certificated, weber.therm XM EWI system for the sports building which has been designed with an integrated approach to sustainability, engineering and architecture. weber.therm XM EWI is a lightweight system incorporating thin-coat polymer render with a mesh cloth reinforcement. More than 4,500m² of EWI has been installed. The specification was calculated by Saint-Gobain Weber to attain a low U-Value of 0.25 W/m²K, which was achieved using 120mm thick expanded polystyrene insulation which is both bonded with weber.rend LAC as adhesive, as well as being mechanically fixed to the frame panel substrate. The insulation is protected with an initial 3mm coat of weber.rend LAC render into which the mesh cloth reinforcement is embedded. This is followed with a second 3mm coat of weber.rend LAC which completes the render structure. In preparation for a decorative finish the render surface is coated with weber PR310 pigmented primer and then a final finish using weber.plast TF150, an acrylic based, textured finish that provides a weatherproof, durable and low maintenance architectural façade. Saint-Gobain Weber EWI systems satisfy current Part L Building Regulations and are Energy Saving Trust recommended. www.netweber.co.uk Kingspan delivers OPTIMum performance Kingspan OPTIM-R has formed a key part of the extension of Caldmore Community Primary School. When a rise in the local population forced the school to double its intake of pupils, architects at Walsall Council were faced with the challenge of extending the building in the limited school grounds. A new two storey extension has been constructed on a steep embankment between the playing fields and the school, allowing the lower level classrooms to open directly out onto the playing fields, whilst the floor level of the first storey rooms match those in the existing school building. A ‘play deck’ sits on the roof of the lower level corridors and ancillary rooms and to minimise heatloss from these rooms without exceeding the height threshold of the classroom floors, a Kingspan OPTIM-R Roofing System was specified along with tapered Kingspan Styrozone H 350. The system’s vacuum insulation panels feature a microporous core which is evacuated, encased and sealed in a thin, gas-tight envelope. This allows them to deliver good thermal performance from a minimal product thickness, with a thermal conductivity of 0.007 W/m.K. Stoneleigh Services installed 30mm Kingspan OPTIM-R panels above a vapour control layer on the concrete roof slab and a further layer of tapered Kingspan Styrozone H 350, in thicknesses from 30mm to 160mm, was then laid above this. This layer of tapered insulation ensures effective drainage of surface water which filters through a porous rubber play surfacing. The build-up delivers a final U-Value of 0.16 W/m².K. www.kingspaninsulation.co.uk 01992 801927 www.almhm.co.uk
