Abstract A sash structure, formed of angular connection elements which are engaged to the sides of a frame and to which designated components are integrally formed for the functionality of the sashes. Such components as hinges, guide selvages of closure latches and the like are included in the frame structure. The connection elements are formed by the angle or corner of the branches inserted in concurrent sections. Extension portions are employed follow the shape of the sections to complete the corner and combine with the balance of the structure.
