The work consists of 1 section, conclusions, list of references of 9 items, contains 6 figures and 6 tables list sources 1 page Object of research - fire vertical multilayer walling buildings. Purpose - to develop a methodology for calculating unsteady temperature field to determine the fire resistance of vertical multilayer enclosing structures of buildings using polystyrene, mineral wool, steel, concrete, fiberboard and foam. Research Methods - analytical method for the study of unsteady temperature field in a multilayer envelope, based on the laws of thermal physics, thermodynamics, heat transfer, physical and mathematical modeling. The result - the analytical solution of unsteady heat conduction problem for multilayer designs (plane-parallel layers) using Green's function, which is carried out by heating the convective heat transfer to the environment, the temperature of which changes with time for the logarithmic law (standard temperature conditions or temperature, which creates oven test).
