Façade Tests on Fire Propagation along Combustible Exterior Wall Systems

With regard to fire protection for exterior walls of a building, only fire-resistive performance is considered, according to the current building standard law of Japan. In previous authors' studies, a new test method for evaluation of fire propagation along combustible cladding was proposed using primarily test specimens of facade walls with exterior thermal insulation without vent layers. In this paper, newly made results of facade fire tests also with other specimens of combustible facades, such as sandwich panels, photovoltaic sheets, combustible coating materials, and exterior insulation with vent layer, are discussed.
