Kombisystem plus is the new BERTRAND central gasket system with a stable bar in the window frame. The central gasket bar effectively protects the mechanical parts in the window from external factors. Central gasket systems stand out for their excellent insulation qualities.


It’s a perfect combination, increased burglary protection and passive thermal parameters. The best quality of materials, deep six-chamber design on the frame and sash and thoughtful arrangement of seals system guarantee the highest thermal and sound dampening propeteries.

Its outstanding static properties make Kombisystem Plus ideally suited for building large elements with acrylcolor surface finishing. BERTRAND’s STV bonding technology means that Kombisystem Plus windows can be further upgraded for stability and safety of use.


Even the standard version of the Kombisystem Plus system is one of the safest options around. But the Kombisytem Plus system’s new central domed gasket makes the burglar’s job much harder. Most break-ins start with the window being levered out: the intruder slides a screwdriver between the frame and sash. The sturdy new dome is an effective barrier against this.
