Termowizja w ocenie jakości przegród budowlanych

W artykule przedstawiono zastosowanie badań termowizyjnych w ocenie jakości cieplnej przegród budowlanych. Opisano wymagania w zakresie prowadzenia pomiarów kamerą termowizyjną w budownictwie oraz główne czynniki wpływające na otrzymywane wyniki. Na praktycznych przykładach pokazano analizę badań zestawiając wyniki pomiarów termowizyjnych z obliczeniami. Dla badanych fragmentów przegród budowlanych omówiono występujące defekty i anomalie termiczne.

In the paper principles of using the infrared thermography method in building engineering are presented. The first section contains the introduction to the topic of using thermography in building engineering. Defects of building partitions which can be detected by infrared camera are described. The second section gives a short description of the factors which influence the quality of thermo-grams. According to the authors, the main factors are: infrared camera technical parameters, keeping the rules for performing investigations, knowledge of a building structure, ability of making the computer models of building partition connections which can be used to verify the investigation results. The third section presents a short overview of the investigation procedures used for taking measurements during building diagnostics. In the fourth section a way of taking the fundamental and subsidiary measurement is given. The diagnosed defects and anomalies for all partitions and connections between them are described. Several chosen thermograms made during investigations are shown in Figs. 1, 2, 4 with description of the defects. Verification of the selected ther-mograms was performed with the computer program KOBRA. In the summary some guidelines connected with the way of presenting the results of thermal diagnostics of buildings are given.
