External Thermal Insulation Composite Systems (ETICS) are widely utilized to increase the energy efficiency of buildings by minimizing heat loss through exterior walls. However, when improperly installed, thermal bridges are formed, significantly decreasing the overall thermal performance of the façade system. This study aims to identify installation defects in ETICS facades by characterizing thermal bridges and their impact on energy performance. The selection of infrared thermography as the primary technique for detecting thermal bridges was based on its ability to reveal surface temperature variations quickly. In-situ thermographic examinations were performed on a case study edifice to discern prevalent installation deficiencies. This inquiry offers a methodical framework for identifying and scrutinizing ETICS installation shortcomings through thermographic imaging, thereby providing valuable insights for enhancing insulation methodologies. The investigation disclosed that thermal bridges predominantly manifested at the junctures of walls and floors, around window apertures, and at points of external element attachment, culminating in increased thermal losses, condensation issues, and risks of mold proliferation. The evaluation of the recognized deficiencies underscored a pressing necessity for elevating installation quality control measures and rigorous compliance with established protocols. The research outcomes underscore a fundamental imperative for amalgamating inspection strategies with preventive measures to bolster the energy efficiency and longevity of ETICS facades. Prospective research endeavors should concentrate on the advancement of detection methodologies.
