Althougt there deaf parts behind the structural silicon curtain wall system used on the outdoor walls, full glass wiew was asked for the building. Tempered heat-glass and black stone load was applied on the parts that are in front of the full walls and the desired wiew was obtained and in this way the heat transfer capacity of the outer wall decreased less than 2,5W/m2K. Bombed glass was applied to the walls at the entry side of the building. In the structural silicon curtain wall system the 17mm emptiness between the glasses can be seen from the front and the leak proof between them is in compliance with DIN 7863 by means of gaskets that are resistant against UV, radiation, ozone, climate and heat changes. In the upper end of the building there is an eave made pf composite plate cladding over the steel construction.
