This SpringerBrief presents strategies for fire mitigation based on combustible assembly
systems of exterior walls. Providing background information on common exterior wall systems
the mechanisms of fire spread and case studies it examines the difficulties in controlling a
fire with several materials and assembly methods. The brief compiles information on typical
fire scenarios which involve the exterior wall along with further exploration into test
methods approval and regulatory requirements for the various assembly systems. Offering
testing approaches for possible mitigation strategies the brief takes into account that
current commercial wall assembly systems are constructed to improve energy performance reduce
water and air infiltration and allow for aesthetic design flexibility. Exterior Insulation
Finish Systems metal composite claddings high-pressure laminates and weather-resistive
barrier systems all have components which directly impact the fire hazard. Recommendations for
future exterior wall construction are based on identified knowledge gaps.
