Abstract:
A fireproof/bullet-proof safety glazing that includes a laminated assembly I of glass sheets, the laminate I, the glass sheets of which are assembled by means of thermoplastic interlayer sheets and n layers of intumescent material made from hydrated alkali silicate, with 1≤n≤3. The laminate I also includes a fireproof module comprising the n layers of intumescent material made of hydrated alkali silicate and n+1 glass sheets, the module being flanked on either side by at least one interlayer thermoplastic sheet and at least one glass sheet. The laminate I does not include organic glass sheets made from a polymer material that is rigid at ambient temperature. The glazing includes at least six glass sheets.
