Abstract

Method of manufacturing fibre boards, in which the fibre boards, after manufacture, are subjected to an impregnation treatment by which it is possible to manufacture fibre boards which are hardly flammable and which attain fire classification B1 according to DIN 4102. For this purpose, according to the invention the fibre boards are to consist of resinoid-bonded compressed wood fibres and are to be provided with a paraffin emulsion and/or other waterproofing agents, and the boards are to be impregnated with an aqueous salt solution so that they contain, after subsequent drying, 100 to 300 kg of salt mixture per m<3>.
