In order to be able to implement the particular design of the architecturally demanding building, particular emphasis was placed on system compatibility and the colour scheme. Thus, heroal was selected as the appropriate partner for window, door and façade solutions. In addition, thanks to our in-house coating system, heroal products offer excellent, long-term colour stability, gloss retention and weather resistance. The window elements of the heroal W 72 system were optimally integrated into the heroal C 50 façade solution in mullion-transom construction - thanks to the modular system design of heroal. The system fulfils the highest requirements for effective thermal insulation and this with a filigree viewing width of 50 millimetres. The installed windows had to be fitted with millimetre accuracy, since the prefabricated, sometimes up to 11 metre long, sheet metal panels allowed for no tolerances. With the door system heroal D 72, a solution was installed, which also withstands high levels of use - an aspect that should not be ignored in public buildings.
