ACOUSTICS
The BioFold product is not only a beautiful and sensorial finish for your walls but has also perfect sound damping properties. It reaches very high αw-value and Noice Reduction Coefficient (NRC) which are values used to define the sound absorbing properties of a material or construction.
The BioFold Acoustic panel has been optimised by adding absorption material from textile residues and reaches a maximum αw of 1,0 (on a scale of 0,0 up to 1,0) and a very high NRC of 0,95 (on a scale of 0,00 up to 1,00) and reaches as a result of this a absorption class A.
The BioFold material combination has been tested for acoustic properties according to ISO 11654 and ASTM C423.
