 In this paper the authors define sufficient conditions for existence of optimal thickness of a flat isotropic wall with a heat insulator and an interlayer in the form of a heat-activated padding which operates on the principle of feedback providing a minimum steady hottest-spot temperature of the wall. The unprotected side of the wall is cooled by the medium with a constant temperature and the heat transfer coefficient, and the side of the wall whith the heat insulator is affected by a heat flow in pulse-periodic mode.
