Abstract
The present invention relates to a method of assembly, in a furnace in vacuum conditions or under a neutral atmosphere, of two parallel plates leaving a closed internal space, consisting, in a first step, of performing a peripheral sealing by means of a first seal fusible at a first temperature, while maintaining open at least one opening of communication with the internal space and, in a second step, of closing the opening by means of a closing element with the interposition of a second seal fusible at a second temperature lower than the first temperature.
