Abstract: A glass wall, in particular for a sports area, is formed of toughened glass sheets and drilling of the sheets obviated or minimised by assembling the glass sheets edge-to-edge, with a pair of resiliently lined side channels fitted to the end pair of glass edges and with resiliently lined top and bottom channels fitted to the top and bottom edges respectively of the glass sheets, each pair of abutting glass edges being overlapped by a pillar with a resilient strip in between, and a door may be formed by a glass sheet with pivots secured to the door and the top and bottom channels or the top and bottom of an opening in a wall to which the channels are secured, with a small hole in the door for access to a latch carried by the door and engageable with one of the pillars flanking the door.
