A very large percentage of the UK's manufacturing capacity for building insulation is located in Wales. Including the two largest factories for steel-faced insulated panels used on commercial and low-rise residential refurb (Flint and Shotton) and Rockwool's only UK mineral fibre plant in Bridgend. Knee-jerk reactions inspired by Westminster politicians seeking quick post-Grenfell sound-bites both threaten Welsh jobs and risk stifling product innovation. The current Welsh Government consultation on banning 'combustible' products above 18metres simply parrots the MHCLG consultation, with the same in-built bias in favour of a ban. Simply implementing Hackitt's recommendations, insisting on as-built system tests rather than laboratory investigations into individual elements of the as-built system and focusing on the responsibilities of contractors and the competences of installers is the only way towards genuine fire safety.
