System description
The three-chamber system, design with a profile groove in Euro standard and the groove used in windows and balcony doors made of PVC.
The structural depth of the frame is 52 mm and 60 mm for the wings. The system allows using a wide range of hardware and ease to work. Three-chamber profile provides the element with higher stiffness, thus the construction may be of larger size. Thanks to the modernization of sealing elements, there is no need for a drip, what positively influences the elevation beauty.
