It displays, however, two fundamental drawbacks, viz. it is susceptible to corrosion and not very fireproof. In the case of a conflagration it soon loses resistance and its elements undergo considerable deformations. Both these disadvantages can be minimized by applying adequate safety measures. The paper deals with the effect of the physical properties of the material used as fireproof insulation on its effectiveness. Special attention has been devoted to the problem of the increased value (even by several times) of the overall heat-transfer coefficient resulting in a change of temperature. In the analysis Fourier-Kirchhoff's equation was applied. The temperature of gases in the zone of the conflagration has been assumed, basing on the standard curve ''temperature versus time" provided in the Eurocode EN 1991-1-2.
