The two-track sliding door system stands out because of its innovative design: the sash profiles guarantee best possible resistance to warping because of the use of new insulating strips.
The insulating strips have been especially developed for the sliding door system and, due to their excellent static features, make the manufacture of very large sashes possible while at the same time offering ideal protection against warping of the profiles due to temperature differences (bi-metal effect).
During the design of the system, particular attention was paid to optimising production as regards economy of time and simplified processes. For the first time, the newly developed labyrinth profiles are integrated into the production of the sash profiles. This way, production times are reduced – the separate installation of these profiles during the manufacture of the sashes is no longer necessary. In addition, the labyrinth profile provides for a very narrow central joint with a face width of only 62 mm, although all of the four corners of the sash are mitre-cut in one production step. Cutting in the composite profile is also no longer necessary, since the new insulating strips effectively minimise the bimetallic effect even without further processing. Furthermore, the entire system consists of a reduced number of components for the sake of keeping its complexity as low as possible. That way, the efficient and reliable processing of the system can be guaranteed.
