Abstract: Building insulation materials are the building materials which form the thermal envelope of a building or otherwise reduce heat transfer.Many insulations are made from petrochemicals and may be a concern for those seeking to reduce the use of fossil fuels and oil.Some insulation materials have health risks, some so significant the materials are no longer allowed to be used but remain in use in some older buildings such as asbestos fibers and urea.Also, the cost can be high compared to traditional insulation.This work presents a study of numerical simulation aiming at the role and the influence of the insulation by the mud Reduced like a local material in the town of Bechar located in the Sahara of Algeria, or one is interested in a comparative study for pursued these goals.In this context, an analogy was used for the functions which are discretized by the finite difference method and integrated in the CFD code which is based on the finite volume method.The effects of various physical parameters such as, the Rayleight number, insulation by the mud as local materials in Sahara of Algeria are studied.The Rayleight nember varies between 10 3 and 10 6 , .The obtained results are of fundamental interest and can be relevant for the development of efficient heat exchangers.This technique has proven that the rate of heat transfer is minimized up to 37%.
