A device for the formation, by pyrolysis, of a coating of metal or a metal compound on one face of a hot glass substrate which is in motion by bringing the face into contact with a gaseous reagent includes a roof; support device for conveying the hot glass substrate along a path through a coating chamber defined between the roof and the face of the hot glass substrate; at least one reagent gas inlet in the form of a slot opening directly into the coating chamber and extending transverse to the path of the hot glass substrate for supplying and distributing gaseous reagent to the coating chamber; and at least one exhaust gas outlet for discharging exhaust gas from the coating chamber. At least during operation of the device a movable shield device is positioned in the coating chamber adjacent the roof thereof, and, prior to operation of the device, the device includes a device for positioning a movable shield device in the coating chamber adjacent the roof thereof, to reduce the formation of deposits on the roof of the coating chamber.
