A method of installing a viewing panel within a through-aperture into a substantially vertical surface is disclosed. The viewing panel comprises a plurality of panes, and at least a first pane has first and second ends opposed to one another and projecting relative to corresponding first and second opposed ends of other pane(s). At least two opposed slots are provided in the surface of the through-aperture. At least part of the first end of the first pane is slid in a first of the at least two opposed slots. The pane is rotated relative to the substantially vertical surface until the second end of the first pane corresponds substantially to the second of the at least two opposed slots. The second end of the first pane is slid and abutted in the second slot, and at least a portion of the first end remains located in the first slot. |
