The Concertina system is designed specifically to cater for the lower end of the spectrum with regards to sound attenuation. Ranging from 15dB RW to 35dB RW, the Concertina system is incredibly versatile and surprisingly effective as a budget solution.
Sound reduction dB ratings are often quoted from laboratory test results which are misleading in respect of final performance values. They are merely useful for initial specification purposes. Independent on-site tests as carried out by Croxton are recommended as in-situ results will differ from laboratory test certification and are therefore the only true guide to achievable sound attenuation.
