A sash for doors or windows includes two spaced apart glass sheets, a spacer element interposed between the sheets to define a closed inner perimeter zone and an open outer perimeter zone. A structural sealing/adhesion component runs along the outer perimeter zone and occupies a volume to permit contact with the spacer element and the glass sheets. An element for housing accessory components for supporting and/or operating the sash is associated with the structural component for each side of the glass sheets. Each element includes a rigid profile having, in cross section, at least one closed base side and two flaps each formed by a stretch perpendicular to the base side and a recessed stretch, parallel to the base side, to form a channel with an opening The rigid profile is associated with the structural component along the outer surface of the base side.
