The work proposed in this article is essentially based on the characterization of the thermal behavior of wooden structures. In the context of fire safety, wooden constructions must be subjected to standardized fire resistance tests. We focused our study on the numerical modelling of fire behavior of the wood according to the progress of vaporization reactions and pyrolysis. The numerical  model includes taking into account the thermal degradation of the wood (pyrolysis) and updating the thermal properties of the wood as a function of temperature. For this, we presented the equations of conservation of matter and energy. These equations are solved by the method of finite volumes. The results are compared with a fire test of cellulosic composite panels.
