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 (D); - a spacer and joining element interposed between two inner surfaces facing each other of the two sheets of glasses 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 ; - a structural sealing/adhesion component applied along the outer perimeter defined by the cavity ; the structural component occupying a volume (P) 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 of the two sheets of glass , characterised in that it comprises at least an element for housing accessory components for supporting and/or operating the sash associated with the structural component , for each side defined by the first and second sheet of glass ; each element being composed of a rigid profile having, in cross section, at least one closed base side and two flaps , 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 (D); - a spacer and joining element interposed between two inner surfaces facing each other of the two sheets of glasses 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 ; - a structural sealing/adhesion component applied along the outer perimeter defined by the cavity ; the structural component occupying a volume (P) 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 of the two sheets of glass , characterised in that it comprises at least an element for housing accessory components for supporting and/or operating the sash associated with the structural component , for each side defined by the first and second sheet of glass ; each element being composed of a rigid profile having, in cross section, at least one closed base side and two flaps , 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. <EOS>
