A mathematical model and numerical methods to calculate 
the thermal state of a fragment of the exterior timber wall of a building 
are suggested. The character of the distribution of temperature fields 
in homogeneous and inhomogeneous (thermally insulated) timbers and 
the influence of the thermophysical and geometrical characteristics 
of a homogeneous timber sample and warmth-keeping lagging on it are 
determined.
