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) an d 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 th e 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 surfac e from the seal element.
