The present invention relates to an oven door for a domestic cooking oven. The oven door comprises a first inner glass panel (10) in direct contact to an oven cavity (34), a second inner glass panel (12) plane-parallel to the first inner glass panel (10) and a void of air intermediate space (18) between the first inner glass panel (10) and the second inner glass panel (12). The oven door comprises further a reflective layer (22) at an inner side of the second inner glass panel (12) in order to reflect radiant heat from the oven cavity (34) and/or at an outer side of the first inner glass panel (10) in order to reduce radiant heat emission from the oven cavity (34). An outer glass panel (14) of the oven door is in direct contact to an ambiance (36). Further, the present invention relates to a corresponding domestic cooking oven.
