The analysis of fire-resistant materials for wooden building structures was carried out and the need for the development of reliable means of protection to inhibit the ignition process and the spread of flame on the surface of the building structure was established. Therefore, there is a need to determine the conditions for the formation of a barrier for thermal conductivity and to establish a mechanism for inhibiting the transfer of heat to the material. According to experimental data, it was established that the untreated sample ignited for 52 s, the flame spread throughout the sample within 100 s, on the other hand, the sample, fire-protected with the impregnation solution BS-13, ignited for 570 s, the flame spread over the surface only in the first section, the maximum temperature of flue gases was 86 °C, and the flammability index was 3.42. For the sample protected by the "FIREWALL-WOOD" coating, the fire did not occur, because a protective layer of pinocoke was formed on the surface, the flammability index was 0. As a result of research, it was proven that the process of temperature inhibition consists in the decomposition of flame retardants under the influence of temperature with the absorption of heat and the release of non-combustible gases. Formation of soot-like products on the surface of natural combustible material and thermal insulation of a wooden structure. Thanks to this, it became possible to determine the conditions of fire protection of wood, by forming a barrier for thermal conductivity during the decomposition of varnish into foam coke. Experimental studies have confirmed that a sample of wood covered with a fire-resistant coating has withstood temperature effects under the influence of heat flow for 600 seconds. This gives reason to assert the possibility of targeted regulation of wood fire protection processes through the use of fire retardant coatings capable of forming a protective layer on the surface of the material that inhibits the rate of wood burning.
