The wood section is 92x90 mm both for the frame and the sash, in 4 layers laminated wood. The aluminum clad is 23 mm thick for the sash and 19 mm for the frame and so after the assembling the total thickness is 111 mm for the frame and 115 mm for the sash. On these windows a triple pane glass is installed, with two Low Emissivity panes and 16 mm or 18 mm chambers filled with Argon Gas. It is possible to install glasses up to 52 mm thickness. The painting treatment and the structure of the aluminum clads are made with the same technologies used for the other wood-aluminum products.
Greenmix windows and doors have four gaskets in EDPM installed on the frame, that offer a total resistance against the atmospheric agents. The first gasket is positioned on the clad profile, going through all its perimeter without stopping in the corners. The other three gaskets are installed on the wooden frame, and they overlap in the corners to assure an hydro pneumatic thigh system to the window and a great sound insulation. In order to improve the efficiency on the discharge of eventual water infiltrations passed through the first two gaskets, 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, treated with antioxidant products, with tilt and turn opening mechanism and several locking points on the whole perimeter of the sash with a high anti-breaking system level, central lever bolt for the typologies with 2 or more sashes, matt chrome or polished brass hinges coverings and handles.
