Abstract (en)
[origin: WO2007044676A2] A highly protective vented firewall (28) is supported between upstanding columns or beams (15). The firewall is made of an inorganic cementitious material which is preferably inorganic phosphate cement. Vent openings (35) are provided to enable flow of cooling air through the firewall during normal operating conditions. A heat-activatable means (35) automatically closes the vents should a fire occur.
