The Government has used the European system for classifying the combustibility of materials to set the threshold for the ban on the use of combustible materials in the external walls of buildings covered by the ban. The European classification system measures smoke obscuration, though not toxicity. The ban requires that all materials which become part of an external wall or specified attachment achieve European Class A2-s1, d0 or Class A1, other than those covered by exemptions. This means that materials are classified by smoke production as well as combustibility and production of droplets. These classifications impose the maximum possible restriction on smoke production.
