These test results combined enable a Class 0 classification to the Building Regulations in England & Wales. Northern Ireland and the Republic of Ireland, and a Low Risk classification to the Building Standards in Scotland. These tests were conducted on samples of 25mm/1” thickness faced with a reinforced aluminium foil vapour barrier jacket.
