For years we have spoken of Class 0&1 BS476 Parts 6&7. Now is the time we asked for 30 & 60 minutes fire protection. Once fire get to a product it is only one minute & it will burn even with Class 0&1. The recent fire at Grenfell Tower had insulation for Class 0&1. This also happened in China a few years ago with the collapse of a 38 storey building.
Fire protection for 30 or 60 minutes allows time for most building to be evacuated. Over the years more plastic, UPVC, now a more dangerous product polypropylene. All burning ferociously & giving off toxic smoke.
