Patio Doors - PVC S Series

The perfect solution for saving energy

Thermal insulation Uf

> 1,2 W/(m2K)

 The goal was to develop a sliding system that would allow easy and quiet handling of the door up to a weight of 200 kg. It is therefore possible to produce magnificent formats fitted with heavy triple glazing, at a reasonable price.
With this type of sliding door, the door does not tilt, but extends to the side in parallel. When closed, the sash is automatically pressed against the frame with minimal use of force. Ventilation here is not accomplished by the classic tilting of the sash, but by the special position of the handle, when the sash is not completely pressed against the frame.
A simple sash opening system with automatic pressing when closed, guarantees very comfortable entrance to your terrace or garden.

The seven closed air chambers inside the frame profile ensure maximum thermal insulation efficiency, which was previously unthinkable without costly additional measures. The patented combined construction of plastic and aluminum reinforces the profiles so effectively that the steel reinforcements used in conventional profiles can be completely omitted. The removal of these “thermal bridges” significantly increases the insulation performance of these frame profiles.
The window made of Alu Inside profile, which is fitted with heavy triple glazing, has a comparable weight as a window with steel reinforcement, which is fitted with lighter double glaze.


We offer high variety of Aluminum windows and doors. Every order is custom made according to our customers requirements. Our modern construction solutions make it possible to create extremely large g lazed areas and improve building design and interior décor not available with most of our competitors, for example 25’ W x 9’H lift and slide doors. We have almost an unlimited potential in terms of both colors and their different shades for our aluminium components. Another key benefit for our products are the components utilizing multi point locking. This is achieved through a link gear running around the window sash, which operates pins which in turn lock into keepers located around the perimeter of the sash opening. Depending on the size of sash used, there can be up to twelve locking points on any one sash. In doors a six-point lock is used. This comprises of four compression roller pins, one latch and one dead bolt. All the locks on any one sash are operated by one lever and secured by one key. Further this creates insulating advantage as an even sash seal is achieved as well as enhanced security. Pleae note we can perform the installation or assit our customer in an installation consult capacity.
