A new method of identification of internal content of walls builtup from brick or stone bonds has been pre sented by the author. It is hoped that the method under discussion, will replace the until now applied conventional methods consisting in at random revealing the individual portions that are only fragmentary by their very nature. In many instances the physical structures of a building results in differentiation of thermal radiation present in its various portions. The observatio nof façades may, for example, be carried out by recording measurements on a suitably sensitized photographic material. The spot measurements of ultra-violet radiation are conducted with the use of radiometers while the point-and-line analysis of that radiation by means of thermographs. As a result of these observations it becomes possible to obtain the thermal image of a façade surface that is imperceptible for the human sight. The author has carried out a series of experiments on some buildings in Cracow using the ”AGA Thermovision 680” type thermograph manufactured by the Swedish firm AGA. The experiments mentioned above have shown that the method of thermovision enables to identify the brick bonds and to determine their origin as well as to ’’see” the runs of installations inside the walls, the unrevealded craks, the filled up openings and the highly moistened portions of walls.
