Abstract
The invention pertains to a method for manufacturing a formed body with a cavity structure for the sound and/or heat insulation of buildings. According to the invention, pre-foamed polystyrene particles are compressed into a formed body in a mold or on a conveyor belt system under the influence of heat and/or pressure, wherein the degree of compression amounts to 0.2-0.8, preferably 0.3 to 0.7, particularly 0.4 to 0.6, such that a communicating cavity volume is preserved in the formed body. The invention furthermore pertains to a formed body for the sound and/or heat insulation of buildings.
