The thesis analyzes the temperature field in construction details in an envelope of a wooden house. The fundamental task is a comparison of steady and unsteady calculation taking into account or disregarding the material properties depending on temperature. The partial task was to design a construction of envelope for wooden building and on the basis of this construction to create 2-D geometric models in the software Comsol Multiphysics which is based on the finite element method. For the calculation of the temperature field is applied boundary condition of the third order with actual values of the exterior temperature in winter. To maximize the credibility of simulation software are included the equation expressing the dependence on the temperature of material constants of timber and mineral wool. As the final result to the temperature field numerical models of the peripheral wall between stationary and non-stationary plot is analyzed mutual description of the behavior of thermal processes. In the results are further clarified the cause of the construction physical phenomena.
