Abstract:
The incorporation of polyvalent metal ions into a silicate based interlayer in a laminated fire resistant glazing produced using a cast in place process provides an improvement in the properties of those glazings. The preferred metal ions are aluminium ions and zirconium ions. The preferred polyvalent metal compounds are those which are disclosed in EP 1206349 and WO 2004/014813.
