    Abstract

    For the establishment of rational prediction of the fire protection performance of insulated wooden walls, a series of small scale furnace tests are conducted on various types of wall constructions with rock-wool insulation, the most stable practical insulation material. The tests suggest practical predictability of the temperature profile by one-dimensional steady-state heat transfer calculation for walls without cavity, importance of cavity for the fire protection performance of insulated walls, potential predictability of the mechanical integrity from the back-surface temperature of the protection layer.
