Annotation: Because of changes in indoor and, in particular, in outdoor temperatures during a year, external components of a structure undergo a temperature gradient influence. D ifference between the temperatures of indoor and outdoor surfaces can be considerable. This phenomenon is mainly typical for panel buildings without covering. Temperature changes result directly in volume changes of components accompanied with cracks in the gaps between the panels. In the process of reconstruction of building panels, there is performed a rather costly filling of cracks and mounting of overcladding. The overcladding itself considerably reduces thermal gradient, volume changes, and cracks between the panels. Therefore, the overcladding can be regarded as a part of recovery works , and the question is whether cracks should be fill ed as well.
Keywords: cracks, panel buildings, thermal gradient, overcladding, volume changes.
