Due to the glazing being fitted from the outside, a visibly screwed glazing bar can be omitted. With this glazing method, extremely good tightness values are achieved; furthermore, the often large and heavy glazing panels can be easily and quickly installed from the outside. The associated glass retention element guarantees reliable burglar resistance and fall prevention. The result is an aesthetically and technically satisfying lift-and-slide door. As an option, it is also possible to integrate the glazing directly in different threshold systems. Barrier-free designs are also possible. In each case, the visible frame width is reduced to a minimum, thus ensuring an enhanced appearance with maximum opening sizes and daylight ingress.
