A composite material comprising a polymer matrix and granules embedded therein. The invention preferably comprises a polymer matrix comprising one or more polymers and at least one void that is closed to the surrounding environment and that is depressurized with respect to a standard pressure of 1 bar (100 kPa). Provides a composite material comprising, after embedding, a granule embedded in a polymer matrix, a method for producing such a composite material, and use as a thermal insulation material.
