As one of the widely used elements in modern architecture, unitized glass curtain walls not only enhance architectural aesthetics and lighting effects, but their air tightness and waterproof performance have also become important indicators of building quality. In recent years, with climate change and the continuous development of architectural design, issues related to the air tightness and waterproofing of unitized glass curtain walls have gradually emerged, becoming key factors affecting building safety and comfort. This paper conducts an in-depth analysis of the air tightness structural defects of unitized glass curtain walls, reveals the main problems existing in the current design and construction processes, and on this basis, proposes feasible solutions for waterproofing improvement. By combining theoretical research with practical cases, this paper aims to provide technical support and practical guidance for improving the air tightness and waterproof performance of unitized glass curtain walls.
