Illustration of window, lintel, and exterior wall leakage
The compression between buildings causes many walls to crack, form sand eyes, and create holes. Rainwater seeps through these cracks into the walls, washing through the exterior surface and leading to leakage spots on the interior walls.

Environmental factors' impact on the aging of structural adhesives
In the actual application of curtain walls, it is inevitable to be affected by surrounding environmental factors. Such as: rainwater, ultraviolet radiation, and high temperatures, which can lead to discoloration, bubbling, cracking, and even brittleness, cracking, and adhesive failure during use, thereby reducing the service life and severely affecting the safety of the curtain wall project.
2. The glue application is not dense; there is no proper control over the amount of glue at the joint during the collection, resulting in too thin a glue thickness. Since the aging of weather-resistant glue progresses from the surface to the depth, insufficient depth of the glue will lead to premature cracking and leakage. If the sealing of threaded holes is not tight or there are omissions, water leakage channels will form.
