The system that couples the superb technical features of the Isola 68 window with the practical advantages and design of the Dual.
The thick section of the window and the fact that it can house double-glazed sealed units means that it achieves the highest levels of thermal insulation, and is thus indicated for classes A and B of the ClimateHouse energy standards.
