INSULATION Supply chains key for housing In the government’s new Housing Whitepaper, Sajid Javid, writes: “This country doesn’t have enough homes. That’s not a personal opinion or a political calculation. It’s a simple statement of fact.” The Secretary of State is correct. If we are to fix our housing market, a huge number of residences must be built within the next few years. The government estimates that up to 275,000 new homes need to be created every year for the foreseeable future to meet the rising demand. Of course, it’s easy to draw attention to the weaknesses in Britain’s housing market, but actually building the much-needed homes within the stated timeframe will place a huge amount of pressure on the construction sector. The massive workload will mean all industry stakeholders will need to have the upmost confidence in the reliability of the products they make use of. Over the next few years, those responsible for sourcing the materials needed to build these homes must protect themselves against any unexpected issues around product availability. This will mean placing their supply chains under heavy scrutiny and anticipating any potential New BIM objects from Kingspan Insulation OPTIM-R in Aberdeen 054 APRIL 2017 RCIMAG.COM By Stuart Dumbarton, senior product manager at Isover material shortages or market volatility. There are certain products within the construction market that are a safer bet for specifiers than others, due to the nature of the materials they comprise. Products making greater use of recyclable materials like glass, for example, are in my opinion unlikely to ever be in short supply, as long as people continue to sort their rubbish. In the UK, the current recycling rate for glass products is at a healthy 67%. Resource efficient It’s often quite easy to find out from product factsheets or from manufacturers which materials in the market are more sustainable and ethically sourced. Our glass mineral wool insulation solutions, for example, are made from up to 86% recycled glass. Glass is a resource efficient material which means it is always readily available, making production issues extremely unlikely. As well as never being in short supply, high-end glass mineral wool products – such as our cavity wall (CWS) and Timber Frame ranges – also provide an excellent level of thermal performance once installed. In addition, they help ensure optimum acoustic comfort within buildings, helping families make the most out of their living space. Both ranges have an A1 Euroclass fire rating, which means they are officially designated non-combustible. These strong, flexible, resilient and thermally efficient products are able to save homeowners money at the same time as cutting their carbon footprint. Sustainability was another focus of the white paper, with the document suggesting that priority will be given to building more sustainable and energy efficient homes. It also hinted that there may well be a review of the cost effectiveness of our current energy performance standards. Sajid Javid described the traditional pace of UK house-building as “sluggish at best.” Now the government has made solving the housing crisis a national priority, the construction industry must ensure it is in a strong enough position to support its ambitious plans. www.isover.co.uk Kingspan Insulation is helping to streamline the specification process with the release of over 500 new flat roof BIM objects. The objects, available on Kingspan’s U-value Calculator app and website (www.uvaluecalculator. co.uk), cover a wide range of green and warm roof constructions, all featuring high performance Kingspan Therma range products. From the intuitive U-value Calculator menu, users can specify their desired U-value and adjust virtually any element within the construction. By ticking a request box at the end of the calculation process, users can now have the BIM object for their Therma range flat roof construction sent to them via email along with their U-value calculation. The objects are attached as a ZIP file in both IFC and Revit formats. Kingspan Insulation says its U-value Calculator is available as a free app for Apple, Android and Windows devices. It includes over 8,000 calculations for floor, wall and roofs, all precalculated by a member of Kingspan Insulation’s Technical Services Department which is approved under the ‘BBA/ TIMSA Scheme for Calculation Competency Part 1 – U-value and condensation risk’. Where appropriate, these calculations also take into account fixings and bridging factors. In addition to the new flat roof objects, a wide range of Kingspan Insulation BIM product objects are also available for free download from the NBS National BIM Library. www.kingspaninsulation.co.uk GP practice staff in Aberdeen city are enjoying a new and improved environment at their purpose-built facility, with the help of the Kingspan OPTIM-R Balcony & Terrace System. Woodside Fountain Health Centre is a bespoke build replacing the Woodside Medical Group’s premises on Western Road. The triple primary care facility offers a collaboration of services within the fully accessible building. The new health centre is comprised of 12 consulting rooms, a minor procedures room, treatment rooms, an NHS dental practice, and a team of community nurses. The project was overseen by contractors Miller Construction, which was acquired by Galliford Try in 2014. The centre features a spacious roof terrace. To insulate this, whilst also maintaining an even transition from the internal area, 30mm thickness of the Kingspan OPTIM-R Balcony & Terrace System was specified. Unlike conventional insulation, Kingspan OPTIM-R panels feature a microporous core which is evacuated, encased and sealed in a gas-tight envelope. This design allows the panels to achieve Kingspan OPTIM-R has a BDA Agrément certification for thicknesses of 20-40 mm outstanding insulation performance with an aged thermal conductivity of 0.007 W/m.K, enabling the target U-value of 0.15 W/m².K to be achieved with the slimmest possible construction. A further layer of Kingspan Styrozone was installed above the system, followed by a waterproof membrane and the final balcony surface. The Kingspan OPTIM-R Balcony & Terrace System also includes OPTIM-R flex infill strips which can be cut to size, ensuring the System can meet all design requirements. When installed to Kingspan Insulation’s guidelines, the Kingspan OPTIM-R Balcony & Terrace System can provide outstanding long-term thermal performance over the lifetime of a building. www.kingspaninsulation.co.uk/optim-r
