In order to provide a heat-insulating system which is intended for the vertical, load-dissipating connection of building parts to be produced from concrete and can be used in a variable manner and adapted, in accordance with the respective static requirements, to a large number of applications, the invention specifies a heat-insulating system which has an insulation body and one or more compressive force-carrying elements. The insulation body is configured with a plurality of apertures, which extend vertically therethrough from an upper side to an underside and into which a variable number of the compressive force-carrying elements, formed as individual compressive force-carrying elements, can be inserted. It is thus possible for the number and/or the nature of the individual compressive force-carrying elements to be adapted to the static requirements present in each case, and therefore the heat-insulating system is suitable for a large number of different applications.
