The thesis deals with the detection of thermal bridges of the building envelope of SCHOTT s.r.o. and MANNTECO s.r.o. The aim of this diploma thesis is the experimental verification of thermal defects and anomalies of peripheral structures of buildings. The qualitative infrared thermography method is used to ensure the results. The results of the experimental measurement revealed thermal defects and anomalies on the peripheral shells of the measured objects. The acquired thermograms are evaluated. With regard to the measurement results, construction operations are proposed, which are suitable for the elimination of thermal defects and anomalies of the building envelope.
