This invention relates to soundproofing boards based on mineral fibers and thermoplastic binders, which may also contain fillers, fire retardants and hydrophobicizers and which as binders contain 4 to 20%, based on the weight of the mineral fibers, of polymers having a glass temperature range of 30 to 80 ° C from at least 60% by weight, based on the copolymer, of 1 to 4 carbon atoms (meth) acrylates and up to 40% by weight of acrylonitrile and / or styrene. |
