Combustible cladding is banned on high rise buildings and non FR polyethylene composite panels on all new buildings. The UK Government’s revision of fire safety guidance is part of an ongoing tightening of building regulations following the Grenfell fire. As well as requirements on fire service information on buildings and evacuation alert systems, restrictions on combustible materials in or on external walls are extended. The already announced ban on combustible materials in new residential buildings over 18m high is extended to hotels, hospitals and certain other buildings. Combustibility is restricted for materials in or on external walls for residential buildings 11 – 18 m. Metal Composite Material panels (MCM) with non fire-safety treated polyethylene core are banned on all new buildings of any height.
