Insulate News Kingspan Tek Insulation Underpins Efficient Cambridge Virido Development irido, the new high energy efficiency housing development in Cambridge features Kingspan’s TEK V Building System of Structural Insulated Panels (SIPs). Located in the rural suburbs of the University City, Virido was developed and constructed by Hill. The development features 208 apartments and townhouses in a grid of quads around a central courtyard. A high performance fabric specification, was achievable thanks to the Kingspan TEK Building System and was designed by Pollard Thomas Edwards. The Kingspan TEK Building System comprises a high-performance insulation core sandwiched between two layers of OSB/3. The lightweight panels were designed and factory cut to the project’s unique requirements by Kingspan Timber Solutions. This ensured a fast-track erection programme with minimal onsite adjustments and waste. To maximise the energy performance of the dwellings, the envelopes of all properties on the development have been designed to be extremely airtight. This was a key consideration in the specification of the Kingspan TEK Building System as its unique jointing system and OSB/3 facing supports highly airtight constructions. On completion, each property was individually assessed and achieved recorded air leakage rates of below 1.5 air change per hour @ 50 pa. The highly airtight design necessitated the use of mechanical ventilation heat recovery systems (MVHR). These systems use the heat from the outgoing stale air to heat incoming fresh air, further reducing heating demand and maintaining comfortable internal living conditions. The Kingspan TEK Building System also contributed towards the excellent fabric performance of the properties as Heike Messler from Pollard Thomas Edwards explained: “The walls of the Virido properties allow approximately 20% less heat loss than a typical building, without having to compromise on room sizes. This high level of thermal performance means that the homes don’t really need radiators, but we have included them for personal comfort.” Both the Kingspan TEK Cladding Panel and Kingspan TEK Building System panels are also available in a 172 mm thickness, offering enhanced insulation performance with U-values of 0.17 W/m2.K or better. The manufacturing facility where the panels are produced carries both FSC® (FSC®-C109304) and PEFC Chain of Custody certification. As standard, the OSB/3 facing of all Kingspan TEK panels is PEFC certified. 12 BBA Tests Even Tougher with Heavyweight Instron Testing Machine OTest experts at the British Board of Agrément (BBA) are making full use of their new Instron universal testing machine to pull, squeeze, twist, bend and tension building products under assessment, including those for the roofing, cladding, highways/car parking, house-building and civil engineering industries. The new load frame equipment is an upgrade to the BBA’s previous machine, offering an additional test space, a widened scope of products to be tested thanks to an increased load capacity from 100kN to 250kN, greater levels of accuracy and stability and the latest Bluehill Universal software. Mike Beale, BBA Test Contracts Manager, said: “The new Instron machine can test more than 30 product types, from insulation to membranes, resins, moulded plastics including pipes and window frames to waterproofing systems. It’s a crucial piece of equipment that is in virtually constant use tensioning, flexing, compressing, peeling and shearing products. It is a great asset that is perfect for supporting our clients’ needs. We will continue to invest in new test fixtures to maximize the possibilities of this state-of-the-art equipment.” 13 13
