Safe Operation

The swing panel (in the case of an odd number of panels) is locked by means of a special catch and can thus be carried along safely.


Espagnolettes with 24 mm throw lock the panels into the top and bottom track of the frame ensuring they withstand gales and afford high security. Optional additional security by means of profile cylinder lock.


Carriers with twin ball bearing runners and cardanic upper-running carriages guarantee that the folding glass door slides extremely smoothly and quietly.

Weather Stripping

High rain protection through triple wraparound sealing as well as runner and floor track with upstand. 
Vertically: double EPDM seals
Horizontally: double brush seals with sealing fin.


The exterior of top hung folding glass door is easily cleaned by simply removing the hinge pins.

Weather Stripping

High stability as well as big panels with a great amount of glass due to diecast corner connectors and close fit tongue-and-groove interlocking panel joint.

Height Adjustment

Even after installation the folding glass door can be easily height-adjusted by about 6 mm – which is important if settling of the building occurs.

Width Adjustment

The frame connections can be adjusted widthwise which is important to compensate building tolerances.

Site Procedure 1: Sub-frame Stage

Installation of Sub-frame
– Sub-frame is cut into size on site
– Corner joint is used for ensuring the perpendicularity of sub-frame
– Galvanized strip and Hilti products are used to fix the sub-frame to the wall structure
Advantages of Sub-frame system
– Generally has better water tightness performance
– Can be used for precast or cast in-situ wall systems which do not require plastering
– Allow greater flexibility in the sequencing of works of other trades; the sub-frame is installed first so that the wet trades around the window can be completed before subsequent installation of the main frame
– The main frame are installed after completion of all wet trades around the windows and hence, are subjected to lower risk of physical damages
