GSP® multiframe, the universal adapter profile for the installation of windows in glass sandwich façades, is wind and water tight. This was confirmed by CE testing of the frame profile at the end of April. The individual components of the glass sandwich façade - GSP® and windows - have already been individually tested and CE certified.
Now GSP® multiframe has been tested in the laboratory for air permeability, driving rain tightness and wind load. With success: The air measurements showed a very high tightness of the universal profile both under pressure and suction. Thus GSP® multiframe meets the requirements of class A4. The driving rain tightness corresponds to class R7.
