A new CPD seminar approved by RIBA and the CPD Certification Service, has been introduced by Kingspan Benchmark to examine the development of prefabricated insulated panel systems within the wider context of innovations in unitised building solutions. CPD seminars provide an essential means for architects and other professionals to maintain and expand their skills and knowledge by being introduced to the latest developments within the industry. The new CPD seminar created by Benchmark, discusses the benefits of off-site build wall units that can be over 7 metres high by 3.5 metres wide, combined with on-site dry construction, allowing quicker and safer installation, greater predictability in work schedules and simplifying compliance with new regulations. More specifically it looks at how insulated panel technology has developed from industrial cladding into a more advanced unitised system compatible with a large range of architectural façades from Kingspan Benchmark. In this new unitised wall system, insulated panels are designed to operate as complete wall infill panels bolted to the main steel or concrete frame. This eliminates the need for any secondary support structure and enables spanning from floor to floor by using the wall as a diaphragm between the fixed frame. As a result the system is able to support a wide range of external facade options without the structural complexity of other approaches. The system is highly durable and has outstanding thermal performance allowing the system (excluding façade) to achieve U-values as low as 0.095 (W/m2K). Furthermore because the unitised wall system is installed using mechanical handling, large modules can be fitted quickly and safely without the need for scaffolding, weatherproofing the building and allowing follow-up trades to begin internal fitting while the façade is being installed. Modular building approaches offer solutions to some of the key issues of modern construction, ensuing thermal performance while reducing building costs, and this CPD seminar provides an example of how one approach has developed from standard prefabricated insulation into a full through wall unitised solution.
