Abstract
The window for a hot chamber sealed off from the surroundings includes a multi-pane module. The multi-pane module has at least two transparent panes ( ) held apart by peripheral spacers ( ) and interconnected with the peripheral spacers ( ) in a gas-tight fashion so that the transparent panes and spacers bound an interior space ( ). The peripheral spacers ( ) are provided with at least one through-going opening ( ), each of which is closed with a replaceable, permeable filter pad ( ). This permeable filter pad ( ) permits gases to penetrate the filter pad ( ) for gas exchange in order to prevent pressure build up in the interior space between the panes and spacers, but prevents water vapor and other vapors containing grease, oil and other contaminating particles from entering the interior space. The panes may be composed of thermally and/or chemically prestressed borosilicate flat glass or transparent glass ceramic and the spacers may be composed of stainless steel, aluminum or a sufficiently temperature-stable plastic.
