A process of determination of a percentage of glass surface to treat with a decoating process in a defined enclosed space in order to reach a predetermined level of electromagnetic reception and/or transmission at a predetermined frequency, using a database. The process contains the following: measurement of the inside and/or outside electromagnetic signal amplitude; calculation of an expected attenuation level; identification, in said database, of reference percentages of treated surface where the corresponding reference attenuation levels are inferior or equal to the expected attenuation level; determination of a percentage of glass surface to treat in the defined enclosed space corresponding to the identified reference percentage of treated surface where the corresponding reference attenuation level is minimum.

A fire resistant vacuum insulating glazing assembly includes at least one vacuum insulating glazing unit that has a first glass pane, GP 1 , which includes an inner pane face and an outer pane face and a second glass pane, GP 2 , which includes an inner pane face and an outer pane face. A set of discrete pillars is positioned between the first and second glass panes and maintains a distance between the first and the second glass panes. A hermetically bonding seal seals the distance between the first and second glass panes over a perimeter. An internal volume, V, is defined by the first and second glass panes and is closed by the hermetically bonding seal. There is a vacuum of absolute pressure of less than 0.1 mbar and the inner pane faces face the internal volume, V.
