Product data
More information about the fire classes of our sound absorbers is available the relevant aixFOAM knowledge article.
In the production (foaming) of this acoustic material different sized pores (voids) can arise. Voids are typical for the material, do not represent a quality defect and do not affect the acoustic properties of the absorber.
More information about this product is available, if required, in the accompanying datasheet. We are happy to provide you with this upon request.
Absorption values
The measurements of the sound absorption coefficient were determined according to DIN EN ISO 354 (reverberation room) and refer to an absorber area of 100 cm x 50 cm.
