Acoustic Performance of FireLite
The FireLite range of products provides levels of acoustic attenuation normally expected for glass. For design considerations the following measured values apply:
Rw (C;Ctr) values, dB
|11mm & 12mm||36||(0;-2)|
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.
