<strong>Insulate</strong> News Cladding Solutions Adrian Pargeter, Head of Technical and Marketing, Kingspan Insulation Limited Latest Guidance Following the completion of the Ministry of Housing, Communities and Local Government (MHCLG) largescale testing programme last summer, the Ministry issued a consolidated guidance note clarifying which cladding systems could be considered acceptable for use on buildings above 18 metres. This guidance has now been updated, acknowledging that additional systems have completed large-scale BS8414 tests and achieve a BR-135 classification. This may mean that some buildings no longer require remedial work or that there are alternative solutions where re-cladding is required. Current Guidance The broad guidance remains that any wall system containing a PE cored ACM cladding panel (such as was on Grenfell Tower), even when combined with non-combustible insulation, would not be considered compliant. At the other end of the scale, systems with an A2 rated, solid-cored ACM, are deemed to have passed the test, regardless of whether they are combined with rock fibre, PIR or phenolic insulation, with the proviso that different products from different manufacturers will vary, which may affect fire performance. It is those cladding systems with FR cored ACMs that present the greatest complexity. The Government tests on these systems yielded a pass result for rock fibre and a marginal fail for PIR and phenolic. The most recent advice note for building owners which was updated on 28 March <strong>2018</strong> states: “However, it is important to note that there are many different variants of this cladding and insulation and it is possible that products from different manufacturers may behave differently in a fire.” It should not be assumed therefore, that FR cored ACMs in combination with any rock fibre are automatically compliant. The guidance goes on to note that two cladding systems using FR cored ACMs and one brand of phenolic insulation, have been tested to BS 8414-1 and have achieved BR 135 classification. This means that some buildings, which are insulated with that brand of phenolic insulation, may not require remedial work, or may require less than was originally estimated. The BRE holds a register of all cladding configurations which have been successfully tested to BS8414 at: www.bre.co.uk/regulatory-testing. Remember that BS 8414 results only apply to the specific design tested and seek professional advice and guidance as to whether your system complies. Note also that recent tests may not yet be listed on the BRE website. You can refer to the manufacturers and/or designer of your current system to get the latest information. This means that some buildings, which are insulated with that brand of phenolic insulation, may not require remedial work, or may require less than was originally estimated.

Labour’s Plans to Save Household’s Over £1bn a Year on Energy Bills The next Labour government will save 4 million households at least £270 per year by funding local authorities to deliver ‘street by street’ home insulation schemes. Through an investment of £2.3bn per year to provide financial support for households to insulate their homes, and for local authorities to drive take up and delivery of insulation schemes, the next Labour government will drastically improve energy efficiency, bringing 4 million homes up to Energy Performance Certificate (EPC) C by the end of a parliamentary term.
