Fire resistant vacuum insulating glazing

A fire resistant vacuum insulating glazing assembly comprising:

• i. At least one vacuum insulating glazing unit comprising:
• a. a first glass pane, GP1, having an inner pane face and an outer pane face and a second glass pane, GP2, having an inner pane face and an outer pane face;
• b. a set of discrete pillars positioned between the first and the second glass panes, maintaining a distance between the first and the second glass panes;
• c. a hermetically bonding seal sealing the distance between the first and the second glass panes over a perimeter thereof;
• d. an internal volume, V, defined by the first and the second glass panes and closed by the hermetically bonding seal;
• wherein there is a vacuum of absolute pressure of less than 0.1 mbar;
• and wherein the inner pane faces of the first and the second glass panes (GP1, GP2) face the internal volume, V;
• and
• ii. at least one intumescent unit comprising:
• a layer of intumescent material;
• an intumescent unit glass pane, GPiu, in contact with the layer of intumescent material;
• wherein the layer of intumescent material is facing one of the outer pane faces of the first or the second glass pane (GP1, GP2) and is devoid of an encompassing intumescent unit peripheral spacer over a perimeter thereof.
