Statement of the problem. Studying the durability of construction materials in the aspect of thermal fluctuations is the most complicated, yet the most appropriate method. Considering that this concept does not take into account the changes of the physical structure, it becomes necessary to consider not the material alone but also the configuration of the structure. Therefore it is necessary to make a comparison of two structurally different elements - PVC and wood.Results. The coefficient of the 2-layer composite cross-section (no special connection) is the samefor the PVC and wood elements: kc = 2. The derived coefficient of the 3-layer composite cross- section (no special connection) is within the following range: kc = 3.5…5.5, which calls for a more precise definition.Conclusions. Based on the above experiment, we have theoretically established and experimentally confirmed the regularities of deformation and destruction of PVC elements of the 2 and 3-layer solid and composite cross-section with no special connection. Identifying the thermal fluctuation relations allows us to appropriate the theoretical concepts of the capacity of the construction material in a structure to actual conditions.
