comparison thermal conductivity

All metal structures, including aluminium alloy have a high coeffi- cient of thermal conductivity which, when subjected to an open fire will cause a rapid build up of temperature which may result in flash fires being started in neighbouring rooms or compartments.

Aluminium alloy permanently looses its strength at temperatures above 200 C, and will completely melt at 650 C. Therefore, any fire that affects adjoining structures to the extent of 200 C or more will contribute to structural collapse.
