The system with opening to the outside isn’t very popular in Bulgaria. It is suitable for a not very cold climate and for seasonal residence because unfortunately it cannot bare a glazing thicker than 24 mm. It can be shaped with the CLASSIC or CENTRUM design. You sould keep in mind that the window leaf opens only up to 90 degrees.
