The thermally insulating H-BAU Technik ISOPRO® 120 concrete-to-steel connection elements reliably create a frictional connection between steel structures and reinforced concrete components. The thermal insulation element consists of a 120 mm thick insulating body with a structurally effective framework for the safe transmission of forces. The adjustment plate is continuously adjustable and can be used to compensate any construction tolerances. The elements have national technical approval according to Z-15.7-313 and reliably reduce thermal bridges.
