Going beyond BR 187 when designing for external fire spread
Our bespoke software ensures that designing for external fire spread goes beyond guidance for the most efficient design of complex geometries.
External Fire Spread
Expert design for complex geometries
Simple guidance for external fire spread makes assumptions about fire size, sprinkler benefits and the heating effects if the emitting or receiving façade has an irregular (i.e., not flat) shape.
To overcome these limitations, we developed our own software that which can be used for complex geometries so that the heat flux between infinitesimal surface areas can be determined.
The software offers a greater level of accuracy when compared to the simple look up tables provided in BR 187.
