<p>The invention relates to a multi-layer heat insulating pane element for constructing wall and/or ceiling surfaces of a greenhouse, comprising: a frame construction, a first pane, in particular a conventional commercial glass pane, the edge of which is enclosed by and fixed in the frame construction and held by said frame and a pane, e.g. deep-drawn and consisting of plastic, that is attached to at least one side of the first pane to form a double pane arrangement. The attached pane is dish-shaped and the edge region of said pane is continuously hermetically sealed to the first pane. The cavity is then evacuated and the interior of the attached pane is supported against collapse under atmospheric pressure by means of a plurality of supporting elements.</p> |
