Abstract:

The objective of this study was to investigate the capability of "durable agents" to protect building exterior materials from ignition. The "durable agents" used in this study included: a protein-based, compressed air foam, and two different water thickners, also known as gelling agents. Two exterior wall sections forming a corner were pre-treated with a "durable agent" and exposed to a 50 kW fire for 10 minutes. Flame extension on the exterior siding was recorded during the tests. This study demonstrated that durable agents applied to combustible exterior siding reduce the likelihood of ignition and flame spread.
