Our concertina system is designed specifically for low budget projects. They do however come in three different levels of sound attenuation.
They are as follows:
- 15dB +
- 24dB +
- 31dB +
- 35dB +
These sound attenuations are extremely good when taking into account how light weight this system is.
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 Akurawall are recommended as in-situ results will differ from laboratory test certification and are therefore the only true guide to achievable sound attenuation.
Please note that we are available to provide sound certificates upon request.
