Abstract:
The present invention relates to a novel sound-absorbent foam system in the form of an open-cell mineral-organic material, which can even attain building material class B1 according to DIN 1402 and is used for reducing sound levels, in particular in interior spaces. The material is distinguished by containing lignosulphonate.
