S120LS - PVC S Series - Sliding Systems


Supported by the frame profile enclosing the vent frame. The PVC-U lift-and-slide door system S120LS is equipped with newly developed anti-friction gaskets for improved durability and weather tightness.

Integration in the colour range with a large selection of woodgrains and single colour decorative foils means an almost unlimited choice of colours.

Thanks to the high level of system compatibility, windows and doors can be designed uniformly.

S120LS system will allow you to extend the interior by the garden or terrace when simply sliding a glazed leaf to the side. Perfect choice for low-energy and passive buildings.
