ABSTRACT:
A heat insulation window includes a pair of outer panes (14, 16) defining an interior air space (12) and held apart by a spacing member which as opposed and parallel first and second outer surfaces. A third outer surface extends between the first (21) and second (23) outer surfaces. The spacing member defines a first sealing groove (32) at the junction between the first (21) and third (19) outer surfaces and a second sealing groove (32) at the junction between the second (23) and third (19) outer surfaces. The sealing grooves (32) are filled with a gas-tight seal element. A metal band (34) overlays the third (19) outer surface and has edge flanges (34A,34B) which fit into the first and second sealing grooves (32), isolating the third (19) outer surface from the seal element.
