Black glass elevator

A 10m high glass elevator made of black-coloured GSP® is a design highlight of the Topstar headquarters. The lift brings customers barrier-free directly into the factory outlet of the office chair manufacturer. 19 GSP® elements with lengths of up to 3m were installed horizontally. Due to the unnecessary mechanical retainer of the glass and the concealed tounge and groove connection, a homogenous building envelope is created. It is used by Topstar as a kind of glass screen. In order to be able to exchange advertising messages, all slogans were applied with adhesive foils.
