Hinged window and door joinery is quite common as systems used in living areas. The features expected from these systems can be listed as notably heat insulation and air-water tightness performance, feeling the outside noise at a minimum level, letting the needed daylight into the environment and offering a comfortable working usage.

Hinged systems are very rich in terms of usage options, and besides standard uses such as inward and outward opening door-window, double-axis, transom, pivot, they have many aesthetic-oriented additional solutions such as concealed sash windows and both face doors. In addition, sliding systems and lift sliding systems are applied as system series, providing maximum heat and sound insulation.
