    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 façade walls with exterior thermal insulation without vent layers. In this paper, newly made results of façade 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.

    This work presents a simple model to predict the radiation heat flux from a flame to a floor surrounding it. This heat flux was measured both in an unconfined space (open air) and under a ceiling. Flame lengths, flame temperatures, and ceiling surface temperatures, all of which are necessary to predict radiation heat flux, were also measured. Flame shapes were modeled by two cylinders and two disks representing the impinging flame’s continuous and intermittent flame regions. The emissivity of the cylinders was calculated from the heat balance at the flame surface, and the radiation heat flux to the floor was predicted well by the model.
