Case studies 7 se ca K nauf Insulation has the ability to manufacture bespoke products to cater for a variety of project specifications. As such, the leading insulation manufacturer was approached by Euroclad to develop a tailored insulation solution to meet the acoustic performance criteria of Cardiff’s new Ice Arena Wales. The £16m ice arena will be part of the £400m International Sports Village and will be home to the Cardiff Devils ice hockey team. The scheme will provide a 3,000 seat multi-use arena and separate public skating rink. A big emphasis was placed on the acoustic performance of the building in order to reduce noise pollution for any surrounding buildings and to maintain a comfortable environment for spectators. Kier Construction worked with its Tier One supply chain partners, Massey Cladding Solutions and Euroclad, to develop the roof and walling systems in order to meet the project’s demanding acoustic performance requirements. “With over 3,000m2 of roof area and over 6,000m2 of mansard roofs and walls, we created a bespoke 135mm build-up and required an insulation product that could be installed on all elevations within this,” commented Gethin Williams, Elite Systems supply chain manager at Euroclad. “Our brief, which was laid out at the start to Knauf Insulation, required a product of single density with a high compressive strength whilst not being too dense which could interfere with the acoustics. Our strong relationship and continued business development with Knauf Insulation led us to work with its Technical Support Team to explore a variety of solutions. “By consultation with Knauf, a bespoke product was developed, RS105 RocSlab in 104mm thickness. An insulation solution of this thickness was created as it had to fall in line with the 135mm deep spacer system. Additionally, above the spacer system there will be two layers of weatherboard installed and so it was important that the insulation was flush with the spacer. “It’s been great to work alongside Knauf Insulationon this project, as their knowledge and guidance was critical to developing the right product solution.” Delivering a thermal conductivity of s ie ud st Knauf’s bespoke product for Ice Arena Wales 0.036W/mK, this unique product was developed within Euroclad’s timescales ready for a variety of acoustic and thermal testing, managing to meet the stringent project specifications. Gethin continued: “The overall thickness of the RS105 RocSlab allowed a 16mm reduction in height, weighed less than traditional roofing boards and outperformed the acoustic requirement laid out by the design teams.” A sequence of acoustic tests were carried out by Kier Construction in order to establish what materials were required to achieve the performance figures set out at the beginning of the project. Ray Massey, managing director at Massey Cladding Solutions, commented: “After designing the roof and walling systems, Euroclad supplied us with the insulation materials we required – I was very impressed with the laboratory tested products, as they met our brief accurately.” www.knaufinsulation.co.uk Eco Pod specialist to switches to Actis Hybrid A national company which designs and builds A+ EPC rated buildings has switched to using the Actis mix and match Hybrid insulation system to improve their thermal efficiency even further. Lancashire-based Pod Living Ltd specialises in designer Eco-friendly buildings for schools and hotels and, having trialled the hybrid range on a 100m2 outdoor education centre in a park in Lytham St Annes, has decided to use the system in all its ongoing projects. The centre, in the Queen Elizabeth II community park, is used for various educational activities such as forest skills and as a meeting room by community groups and the charity Park View 4U. This was the first time Pod Living had used the Hybrid range – which consists of an insulation material, Hybris, insulating vapour control layer HControl Hybrid and insulating breather membrane Boost ‘R Hybrid. The Eco Pod, which used 195mm Hybris and H Control Hybrid in the floor and ceiling and 75mm Hybris and HControl Hybrid in the walls, was funded by various organisations including Fylde Borough Council and the Lytham Soroptomists. Pod Living MD Nick Clegg explained: “The end results saw us with an A+ rated building – with an energy consumption of 9.8kWh/m2a – which means it has achieved an A+ EPC and Minus Zero Carbon rating. We were so impressed by the performance, not to mention how quick and easy it was to use; we then used the full system in our next project – a pod containing two sixth form classrooms at the St Mary Magdalene Academy in North London. And we’ll use it from now on in all our pods as www.completecircmktg.co.uk it is better, lighter and cheaper than the alternatives.” Schools are the main customers of Pod Living’s timber framed buildings – for their combination of cost effective extra space, aesthetic appeal and low running costs. With the addition of elements such as solar PV on a feed in tariff, Nick explains, the financial benefits look very attractive. “We wanted to use Eco-friendly insulation products but couldn’t get the U-values we wanted with other green systems. Our Eco Pods, whose panels are made in kit format in the factory before being transported on site, offer a turnkey solution in three weeks. They’re not pre-fab buildings, but are built like a timber frame property. They have the same life expectancy as brick bu [
