A glazing unit comprising a sheet of glass having a coating consisting essentially of silicon on a major face thereof, and a frame for that sheet.

Glazing unit

An apparatus for coating glass with a coating consisting of or containing silicon includes a gas distributor for locating transversely of the path of travel of a glass surface. A gas supply duct supplies coating material in gaseous form and the temperature of the duct is controlled. An elongated open-faced chamber positioned adjacent the glass path of travel communicates along its length with the duct through a gas-flow restrictor that provides gas release from the duct into the chamber at constant pressure along the length of the chamber.

Apparatus for coating glass

A coating consisting of or containing silicon is produced on glass by moving the glass, at a temperature of at least 400.degree. C, past a coating station to which silane-containing gas is supplied. The gas is released close to the glass surface into a hot zone opening towards the glass surface and at a substantially constant pressure across that surface. Non-oxidizing conditions are maintained in the hot zone, and the coating is produced by pyrolysis of the gas on the glass surface.
