%X This article presents the experimental results of stone wool每layered sandwich constructions, with either steel or gypsum claddings, tested under four different heating exposures: 7ˋkW/m2 incident radiant heat flux exposure, 60ˋkW/m2 incident radiant heat flux exposure, parametric time每temperature curve exposure and ISO 834 standard time每temperature exposure. The test apparatus used were a movable radiant panel system, a mid-scale furnace (1.5ˋm3) and a large-scale furnace (15ˋm3). The results show that reduced-scale tests are capable of reproducing the heat transferred through the construction at large scale provided there is limited mechanical degradation. The results indicate that the availability of oxygen is fundamental to the fire behaviour of the sandwich composites tested. Reactions occurring in stone wool micro-scale testing, such as oxidative combustion of the binder or crystallisation of the fibres, have a limited effect on the temperature increase when wool is protected from air entrainment
