    Abstract: Non-flammable insulating materials having good fire resistance and a density of from 80 to 230 g/l, which materials comprise A. from 99 to 80% by weight of inorganic lightweight particles, preferably expanded perlite or vermiculite, B. from 0 to 20% by weight of fibrous or granular inorganic additives and C. from 1 to 20% by weight of a heat-resistant organic high molecular weight binder, preferably a phenol-formaldehyde condensate, and which contain, as an additional binder C' to prevent water absorption, from 0.2 to 4% by weight of an alkylphenol/phenyl/formaldehyde condensate. The materials may be used as heat insulating materials or building materials.
