The article made a systematic analysis of the issues of comfort, efficiency, durability and safety of use in buildings of various types of floor coverings (NP). On the basis of this analysis, position building designers and end-use advantages grounded operators OP based on polyvinyl chloride (PVC), including insulate layer. The risk factors such use of NP, including related to thermal stresses. Experimental study of thermal destruction NP PVC based derivatography method was performed in argon and in air in the temperature range from 298 K to 1298 K. The used high temperature slew rate in time (5, 10, 15, 20, 25 degrees minute). The experiments allowed us to construct a mathematical model of thermal destruction and to determine its kinetic parameters (activation energy, Tn.r. (temperature of the beginning of destruction), pre-exponential factor, reaction order), characterizing the thermal degradation of NP based on polyvinyl chloride in the investigated temperature range. This mathematical model can be used in assessing risk potential NP PVC based in their operation.
