This study has conducted damage assessment and restoration strategy research on ultra-clear tempered insulating laminated triple-silver Low-E glass used in buildings after a fire.Through on-site inspection and standardized testing,a comprehensive evaluation was made of the appearance,sealing,optical performance,thermal performance,and safety performance of the glass in the skylight.The results show that the performance of the most glass samples complies with the standard requirements,while damaged glass was recommended to be replaced and undamaged glass with qualified performance was recommended to be retained.Through the above comprehensive repair strategy,not only the function and integrity of building glass can be restored,but also the building's resistance to disasters such as fire can be improved.
