ARCHITECTURAL POWDER COATINGS THE FACTS ABOUT FIRE By Angus Mackie - QUALICOAT UK & Ireland Chairman There has been a great deal of discussion that has taken
The surface spread of flame on a high-rise dwelling
place of late over the combustibility of the external envelope of some of our high-rise dwellings where aluminium composite panels (ACM) containing flammable cores have been used. These panels are in the process of being removed and replaced to meet stringent new standards. Insurance companies, mortgage providers and other property stakeholders have also had their part to play to mitigate risk and have forced building owners to check for ACM and other issues such as areas of timber decking. All this will ensure a safer building stock for our city’s highrise dwellings.
can cause fire to spread quickly from floor to floor and legislation is now in place to ensure construction designs slow down the spread of a fire through the building envelope, or to stop it altogether, by correctly specifying the materials used in the building project. As a result, new and refurbished buildings deemed to be high-rise, over 18m in England (11m in Scotland), will be considerably safer.

Of late members of QUALICOAT UK & Ireland have seen a rising number of powder coating specifications that request an ‘A1’ classification for combustibility under BS EN 135011. When traced back through to the specifier, the origin of this requirement largely stems from property stakeholders who are misguidedly attempting to mitigate their risk by exceeding the current guidance, standards and legislation currently available. This can add both complexity and costs to projects without any benefit or reduction of risk. When applied at standard industry thicknesses, architectural Polyester Powder Coating (PPC) achieves an ‘A2-s1,d0’ classification. This classification is required for compliance to the amended Building Regulations 2010 (Approved Doc B: Fire Safety) Nov 2018 and accepted as providing the necessary protection from the surface spread of flame on high-rise construction and other legislated buildings.
