Abstract
The invention concerns a multi-layered heat insulating window panel for constructing wall and/or roof surfaces of a greenhouse, comprising:a frame structure, a first pane (12), particularly a customary glass pane which has an edge that is framed and attached in the frame structure and which is kept in position by the frame structure, and a supplementary pane, for example, deep drawn from plastic material, a supplementary pane on at least one surface of the first glass pane, forming a double-glazing arrangement, wherein the supplementary pane has a tray-like shape and the circumferential edge region is glued hermetically to the first pane and wherein the cavity is evacuated and in the interior the supplementary pane is supported by means of a number of supporting elements in order to prevent the pane from collapsing because of the external atmospheric pressure.
