made from aluminium 6060 (UNI 9006/1) series "ALCOA" system R40. Pre-void seal system with central seals, patented black electro-coloured accessories. The windows are divided into identical partitions with uprights set at intervals of 80/90 cm depending on the dimensions of the window band itself. On the inside the condensation water is gathered in a special channel from which it is conveyed to the outside by means of appropriate inclination and special holes made in the aluminium structure. On the outside any rain which may penetrate between the profiles is channelled by a special sheath to holes made in the frame profile and then expelled.
