Abstract

Fireproof building element with a multi-sheet glazing unit of glass or glass ceramic characterized in that at least one of the glass sheets is a fire resistant glass sheet. The building element contains one or more high heat reflective foils arranged between the sheets at a distance from the fire resistant glazing unit. The foils can be put in a rolled or folded form between the two sheets of the building element such that the visible area is not covered, and they can, in the event of a fire, be spread out completely between the sheets.
