CLADDING & SHEETING Cladding in focus: new CPD offering The Metal Cladding and Roofing Manufacturers Association (MCRMA) discusses its new, The Metal Cladding and Roofing Manufacturers Association (MCRMA) has reinforced its commitment to promoting best practice in the roofing and cladding industry with the introduction of Continuing Professional Development (CPD) accreditation for a range of online courses offered by the Association. The CPDs are approved by the CPD Certification Service and are based on MCRMA’s downloadable Guidance Documents which have been drafted by industry experts from across the MCRMA membership. The current CPDs cover the following subjects; wind loading guidance; snow loading guidance and the installation of purlins and side rails. Wind loadings on roof and wall cladding Buildings and their cladding in particular are expected to withstand the worst that the weather can throw at them without risk of failure or loss of function. The CPD on wind loadings introduces the user to the key issues that need to be taken into account when calculating wind loadings on both the roof and walls of industrial and commercial buildings. The CPD explains the factors which can influence the wind loading and the zonal changes around the building envelope. Successful completion of this CPD should ensure that the user understands how wind forces work 032 APRIL 2017 RCIMAG.COM on buildings; the factors that influence wind speed; how wind loadings are calculated, and understand the parts of the building that are especially vulnerable to high wind loads. Snow loading on cladding Heavy snow falls can result in damage to roofs and their supporting structures. Good building design in terms of resistance to snow loading starts with the correct specification of the roof cladding and its supporting structure. In this CPD, the user will learn to distinguish between types of snow load; understand the factors that affect snow loading; appreciate the recommended calculation procedures and be able to distinguish between designing to the British Standard and the Eurocode. In addition, the user will learn how to specify the correct cladding and supporting structure for a specific building and understand the importance of load paths and distribution for pitched roofs. Snow loading is normally calculated by suitably qualified engineers using the latest codes of practice and software. However, all construction professionals need to be aware of the basic principles of snow loading to ensure that they play their part in specifying and delivering a safe building. Installation of side rails and purlins The ability of a steel framed building to perform adequately depends on good interaction between the secondary steelwork and the cladding and crucial to this interaction is the correct installation of the purlins and side rails. The CPD sets out an overview of the issues that need to be addressed in order to meet the performance criteria free online learning offering Wind loading: Buildings and their cladding in particular are expected to withstand the worst that the weather can throw at them without risk of failure or loss of function “The ability of a steel framed building to perform adequately depends on good interaction between the secondary steelwork and the cladding and crucial to this interaction is the correct installation of the purlins and side rails”
