Abstract
A window for a domestic oven is described which has a reduced thermal transmission so that the outer glass surface, which can be toughed, is maintained at an acceptable temperature. Between the surface of an outer glass sheet and an inner glass sheet of the window there is a rare gas filled enclosed volume. Preferably at least the inner facing surface of the outer glass sheet is coated with a transparent layer of reflecting material. A non-evaporable getter material is contained within said enclosed volume.
