Abstract

Describes a test method to evaluate the fire resistance performance of the open-state cavity barrier against fire exposure from below, measuring the time from ignition necessary to effectively seal the cavity and to maintain the seal. Upward fire spread is of particular concern for rain-screen cladding systems.
