A porous, heat-insulating shaped body, obtained by tempering a material mixture having a weight ratio of 1:1, wherein the mixture includes a silicate such as, for example, natural or expanded perlite, natural or furnace slag pumice, expanding clay, or expanding glass, and an inorganic component selected such that the melting point for the mixture of silicate and inorganic component is in the range of a sintering temperature of the silicate and that a gas is furthermore released from the inorganic component in this temperature range. The porous, heat-insulating shaped body functions to control moisture when used in the form of a heat-insulating board or in the form of an admixture for building materials.
