The innovative OPTIMAXX system is characterized by minimalism and visual perfection. The system is based on simple contours which are the leading trend in contemporary architecture.
The expressive shapes of the wings with the rebate inclination of 4° and glazing beads in 90° optics create a unique, modern design. The advantages of the system are complemented by the low assembly height – 426, which allows for the construction of impressive, large glazing.
