Specification
Standards & Performance :
Fixing : The installation of the Sound Attenuation Systems depends on the individual building environment .
The mineral wool infill used in the production of CCL Sound Attenuation Panels achieves a fire classification rating of Euroclass A1 as defined in BS EN 13501 - 1 .
Fixing systems can be provided for soffit mounted applications .
The sound attenuation systems available have been tested to BS6853 D8 . 4 : 1999 smoke emission .
Powder coated steel frames and mounting angles can be supplied for passenger tunnels and other circumstances where aesthetic consideration needs to be taken into account .
Speech Transmission Index ratings ( STI ) depend on the thickness of panel and the application of the systems in unique building environments . Ratings in the range of 0 . 5 - 0 . 7 STI are achievable , although project specific assessment and testing should be sought . The thermal conductivity of the mineral wool infill used in the production of Sound Attenuation Panels is 0 . 035 W / mK .
