Profiles in extruded aluminum alloy En Aw-6060 on the internal and external faces; reinforced polyamide connection core interrupting the thermal bridge; double stop gasket in Epdm; thermal transmittance of the node = 1.7 W / m2K: these are the strengths of the Metropolis system by Fossati Serramenti.
Characterized by a fixed frame available in the reduced section of 65x39 mm and that of 65x58 mm, it has French doors with a low threshold profile with a height of 25 mm. The profile of the door, on the other hand, has a section of 75x60 mm, coplanar with the fixed frame on the outside, glazing beads with square profile and central node with a total width of 102 mm.
The double glazing, with low magnetronic emissive treatment, spacer with warm edge and maximum thickness up to 48 mm, is held in position in the seat of the door profile by a perimeter glass frame and sealed by special internal and external seals, for thermal transmittance Uw = 1.4 W / mqK with Ug = 1.0 for the double-leaf window LxH 1230x1480 mm; Uw = 1.1 W / m2K with Ug = 0.6 for the double-leaf window LxH 1230x1480 mm.
The hinges are of the tilt-and-turn type in hollow hardware (with closing with adjustable pawls) and guarantee a capacity of 100 kg. Metropolis is certified by the accredited laboratory T2i - Treviso: air permeability class on 1-wing window: 4; water permeability class on 1-wing window: 9 A; wind resistance class on 1-wing window: B4.
