The minimalist design window N11, is characterized by narrow profiles. Innovative design features for this system is the result of demand for design minimalism. The sash frame is hidden from the outside so maintaining the uniformity of the external facade and can be used in conjunction with fixed sections and opening sashes.

In the N11 system has a built-in central seal that ensures superior sealing and is designed for small to medium openings. This opening window system has a delicate design appearance with thick aluminium wall profiles (2mm) thus garanteeing structural stability. The aluminium facade is particulary narrow (55mm). Sash frames and glazing bars are hidden from the outside observer thus maintaining the uniformity of the external facade.

In this system there is a solution to the double panel window that allows a clean opening, divided between sashes and includes a combination of fixed sections and opening sashes. The system is built to incorporate an inner shutter between the glass panes.
