The wood section is 70x75 mm both for the frame and the sash, made in 3 layers laminated wood. On these windows a double pane glass is installed, with the internal Low Emissivity pane and 16 mm or 18 mm chambers filled with Argon Gas. In any case, it is possible to install glasses up to 32 mm thickness.
The sealing is made with anti-aging silicone resins on both glass sides, double and at sight on the external side and invisible under the glazing bead on the internal side. The sealing system is guaranteed by two gaskets made in EPDM installed on the frame and overlapping in the corners, in order to ensure to the window a good hydro pneumatic resistance and a great acoustic insulation.
To improve the efficiency on the discharge of eventual water infiltrations passed through the first gasket, on the external lower profile of the frame there are some drainage holes.
The closing system and the operation of the sashes are guaranteed by steel ironware, silver color, with eventual tilt and turn system, and with the possibility of internal mechanisms treated with antioxidant products, with several adjustable locking points on the whole perimeter of the sash.
