Construction element for heat insulation

fadA construction element for heat insulation between two construction parts, in particular between a building part and a protruding exterior part, is provided, and includes an insulating body to be arranged between the two construction parts with reinforcement elements that can cross it and that can be connected to the two construction parts, with at least shear force rods being provided as reinforcement elements. The construction element is here adjusted for the installation in passively energy conserving houses such that the insulating body is provided with a protrusion, which includes open recesses for the upper exit sections of the shear force rods that extend out of the insulating body, and extend in the direction of the supporting building part to the area of the horizontally protruding shear force rod sections so that it laterally overlaps the bent shear force rod sections in their entirety.
