CONCEPT SYSTEM 77 is available in a variety of aesthetic styles to match current trends, while offering all types of inward and outward opening windows and doors. The system’s performance in terms of acoustics, water and air tightness, as well as special applications such as bullet and fire resistance, meet the most stringent European standards. In addition, CS 77 is available in different anti-burglary levels (RC2 and RC3), making it a particularly secure system.
The CS 77 window and door system is available in three different style options. Whether you prefer a more traditional Renaissance style or the very clean and modern lines of the concealed ventilation style, the aesthetics of CS 77 will complement almost any design.
