Illustration of window, lintel, and exterior wall leakage
Building-to-building compression causes many walls to develop cracks, sand holes, and holes. Rainwater seeps into the walls along these cracks, washing onto the exterior walls, where it leaks into the interior walls.

Environmental factors' impact on the aging of structural adhesives
1. During the actual application of curtain walls, it is inevitable to be affected by surrounding environmental factors, such as rainwater, UV radiation, and high temperatures. These factors can lead to discoloration, bubbling, cracking, and even脆ification, cracking, and adhesive failure during usage, thereby reducing the lifespan and severely impacting the safety of the curtain wall project.
2. The adhesive application is not dense; there's a lack of control over the adhesive quantity during the curing process, resulting in excessively thin adhesive layers. Since weatherproof adhesive aging progresses from the surface to the depth, insufficient depth of the adhesive can lead to premature cracking and leakage. Issues like inadequate sealing around threaded holes or omissions can create water leakage pathways.
