A sash for doors or windows, the sash comprising: - at least a first and a second sheet of glass positioned facing each other and parallel to each other at a mutual distance; - a spacer and joining element interposed between two inner surfaces (2a, 3a) facing each other of the two sheets of glasses (2, 3) to define a first closed inner perimeter zone or chamber and a second open outer perimeter zone or cavity for each side defined by the pair of sheets of glass (2, 3); - a structural sealing/adhesion component applied along the outer perimeter defined by the cavity; the structural component occupying a volume of the cavity which is able to allow contact of the structural component at least with the spacer element and with a part of the inner surface (2a, 3a) of the two sheets of glass (2, 3), characterised in that it comprises at least an element for housing accessory components (9a, 9b, 9c, 9d) for supporting and/or operating the sash associated with the structural component, for each side defined by the first and second sheet of glass (2, 3); each element being composed of a rigid profile having, in cross section, at least one closed base side and two flaps (10, 11), each formed by a stretch transversal to the base side and a recessed stretch, parallel to the base side, to form a channel with an opening; the channel of the rigid profile housing an operating components such as an operating rod which are slidable inside the channel; the rigid profile being associated with the structural component at least along the outer surface of the base side; the rigid profile comprising at least one anchoring rib projecting from the outer surface of the base side and immersed in the structural component; the anchoring rib having, in cross section, a form of a keel extending with its vertex towards the spacer element;wherein the at least one anchoring rib having a profile provided with a tubular chamber to define keel-shaped section with a partly wedge-shaped cross section of extension. - at least a first and a second sheet of glass positioned facing each other and parallel to each other at a mutual distance; - a spacer and joining element interposed between two inner surfaces (2a, 3a) facing each other of the two sheets of glasses (2, 3) to define a first closed inner perimeter zone or chamber and a second open outer perimeter zone or cavity for each side defined by the pair of sheets of glass (2, 3); - a structural sealing/adhesion component applied along the outer perimeter defined by the cavity; the structural component occupying a volume of the cavity which is able to allow contact of the structural component at least with the spacer element and with a part of the inner surface (2a, 3a) of the two sheets of glass (2, 3), characterised in that it comprises at least an element for housing accessory components (9a, 9b, 9c, 9d) for supporting and/or operating the sash associated with the structural component, for each side defined by the first and second sheet of glass (2, 3); each element being composed of a rigid profile having, in cross section, at least one closed base side and two flaps (10, 11), each formed by a stretch transversal to the base side and a recessed stretch, parallel to the base side, to form a channel with an opening; the channel of the rigid profile housing an operating components such as an operating rod which are slidable inside the channel; the rigid profile being associated with the structural component at least along the outer surface of the base side; the rigid profile comprising at least one anchoring rib projecting from the outer surface of the base side and immersed in the structural component; the anchoring rib having, in cross section, a form of a keel extending with its vertex towards the spacer element;wherein the at least one anchoring rib having a profile provided with a tubular chamber to define keel-shaped section with a partly wedge-shaped cross section of extension.
