Italian sash windows

The italian sash window is a TZ specialty: a Structural window flush with the facade, opening outwards. By coordinating the interior embrasures, it is possible to completely hide the frame and leaf. The window becomes a painting; seen from the inside, the landscape is complete, without any loss of light. Seen from the outside, a single enameled strip looks like fixed glazing. Only the presence of a stainless steel handle placed on the edge of the leaf indicates that this glazing can be opened. A motorized opening even eliminates any handles.

The italian sash window can easily be combined in a Structural facade, by alternating the fixed and opening windows in the same plane.
