The analysis is made and the main disadvantages of the methods of determining the actual thermal resistance of external walls are recited. The reasons of the high error in measurement results of the methods of determining the resistance of heat transfer are enumerated. The conditions of stationary heat transfer are demonstrated in general case. Conditions of stationary heat transfer for single-layer brick walls are found subject to a coefficient of heat absorption on the internal surface of the wall fence; of the amplitude variation of thermal flow and of the amplitude temperature variation on the internal surface of the wall fence. The parameter of the deviation of the actual temperature distribution from the theoretical temperature distribution in the thickness of the wall fence is infused. A diagram of the laboratory setup, which belongs to the brick building of the 60s-80s of the 20th century, is represented to determine the actual thermal resistance. The additional amendment is introduced to determine the actual resistance of heat transfer, which includes the non-linear temperature distribution in the thickness of the wall fence. Algorithm and the example of determining the actual heat resistance of a single-layer brick wall are given.
