In this paper a two-dimensional conjugated heat transfer both by radiation and conduction in the thermal lightweight insulation layer was investigated. It was assumed that the radiation might be emitted, absorbed and isotropically scattered inside the gray medium. Its walls were opaque, absorbing, emitting and reflecting diffusively. The Alternating Direction Implicit Method and the Finite Volume Method were used for solution of heat conduction equation and radiative transfer equation, respectively. At first the problem was solved sequentially and then by applying the Domain Decomposition Method. Parallel calculations were carried out for two and four sub-domains. Influence of different factors on differences between the results obtained from the parallel computing and from the sequential calculations, on parallel computing efficiency as well as on number of iterations required for heat conduction equation to be effectively solved were studied in this paper.
