A gasket arrangement for a two-panel door (2) or observation window of a high temperature oven (1) has, preferably, two gaskets (5, 6) disposed one on each side of one panel (3) of the door (2) or window around its periphery so as to provide a seal between the panels (3, 4) and to allow sealing of the door or window against a further member, for example frame, of the oven. A layer of vapour impermeable material extends between the gaskets so as to prevent escape of fumes from the oven. The gaskets are preferably of glass fibre, and the vapour impermeable material a metalic foil. |
