ABSTRACT:
A method for producing insulating panels based on mineral fibers and paper fibers is disclosed. The panels are formed by preparing a suspension of mineral fibers, binders and conventional additives in water, forming the insulating panel by applying the slurry on a screen, drying and consolidating the insulating panel. Due to the use of surface active siloxanes, which contain betaine or quaternary groups, a more rapid and better dewatering of the filter residues, which are intended for the drying process, is attained.
