Analysis about infrared thermal imaging detection on building envelope and material defect cases

摘要

In order to explore thermal imaging technologies' applicability in building envelope and material defection, laboratory experiments and field tests have been carried out to record typical defection thermal images in the climate of Dalian area. Based on one typical building defection case, with its thermal images and working drawing, the effect of material and constructions on the nature and reason of its defection has been carefully analyzed, which can lead us to the conclusions that external insulation construction of building envelope of tiles facing can easily cause bursting or dropping accidents in Dalian area.
