Reference document BMT/MTP/F15334/Rev1, samples tested to BS EN ISO 10140-2:2010. Note: The supporting construction consisted of two wall leaves separated by a 150mm gap containing 100mm fibre insulation. The wall was faced on both sides with 150mm plasterboard on 45mm by 90mm softwood support at 600mm centres. Note: Laboratory tested values can normally be expected to differ from measured values in application, according to the situation.
