Fibrous insulating material production employs fibres, optionally in pelleted or granulated form, which are covered with a binder, Preferably, inorganic, animal or vegetable fibre material is covered with gypsum, water-soluble alkali metal silicates, cement mortar or rock-hard, cellulose- and/or latex-containing binders by immersion, spraying and/or addition during pelleting or granulation. USE - Especially for producing a heat and sound insulating building material for insulating cavity walls, roofs and other hollow spaces. ADVANTAGE - Emission of fine particles is prevented both during production and during installation.
