The main results of research of durability of plates MDF (Medium Density Fiberboard), which is based on thermofluctuational (kinetic) theory of strength. On the basis of the kinetic theory was developed an algorithm that allows to predict the service life of wood-fiber plates of average density with different kind of protective and decorative coatings and thickness, and includes a faster way of determining thermoactivation parameters of the material. The paper proposes a new approach to the study of the patterns of destruction composite materials based on wood, as well as the forecasting performance of composite materials based on wood, which is associated with the study of the behavior of internal constants of the material, determining these parameters. The proposed method allows, in addition to the load that acts on the design or material, consider the influence of the temperature and humidity of the environment. We determine the physical parameters of durability rough flooring depending on the thickness of the material used in the construction.
