In the process of designing, building and reconstruction of new and existing farms and milk producing complexes it should be taken in account that heat engineering characteristics of fences (for walls - R0 - 0,68, for floor - R0 - 0,93 m2 kilowatt/hour) do not ensure the optimal parameters of microclimate in cow-sheds at free stall outdoor housing. Rising of heat economy of cow-sheds by increasing the general resistance of heat irradiation makes it possible to lower cash expenses up to 8-14% and energy resources - up to 2-19%. Economy of electricity is 5,8-7,6 thousand kilowatt/hour counting on 1 cow-shed (200 cows), 0,7-2,4 thousand tonns of fuel, animal morbidity lowers up to 4-8,5%, service period – up to 6-9,6%. Cows milk productivity is higher up to 6,6-8,1%. Increasing of heat protection in fences up to 1,26-1,30 m2 promotes the formation of microclimate corresponding to standards of the Republican Regulations of Technological Designing
