The GUTMANN GLS 180 sliding door series impresses with its simple manufactoring, amazing  performance and operation. At the same time, GUTMANN meets the demands of modern architecture with large glazed surfaces. A pleasant transparency is provided due to high incidence of light. The opening and closing of the sliding doors are almost noiseless. In frame manufacture, the blank can be mitred or butt jointed. The symmetrical profile construction for the inner and outer fittings is the example of the simple installation of GUTMANN´s  lifting sliding doors.
