The Connection Between Aluminum Doors And Windows And The Opening Wall Is The Most Common Location For Rainwater Leakage

The connection between aluminum doors and windows and the opening wall is the most common location for rainwater leakage, and the main reasons are as follows:
1. Due to the inherent defects in the building walls adjacent to door and window openings, rainwater can directly penetrate into the interior through the walls under wind loads, especially when the exterior walls are pasted with tiles. This phenomenon is common because there are often micro cracks in the gaps between the tiles. This phenomenon is often mistaken for water leakage from doors and windows because the water seepage area is close to them
2. The filling material did not fill the gaps between the door and window frames and the wall, resulting in hollow valleys or cracks.
The adjustment pad for fixing the door and window frame remains inside the door and window frame, or has not been refilled after removal.
The gap between aluminum doors and windows and the opening wall was not filled with qualified materials as required, such as incorrect or mismatched waterproof cement mortar grades.
5. The size of the wall opening does not meet the design requirements, causing the gap between the shape and size of the doors and windows and the wall to exceed the designated range. A gap that is too small makes it impossible to fill the material, while a gap that is too large makes it difficult to fix the doors and windows, and insufficient filling can easily cause cracks.
The fixed connection between doors and windows and openings is not firm, causing the doors and windows to move under wind load and causing cracks in the sealing material.
After the installation of doors and windows, the connection between the outside of the doors and windows and the wall is not sealed, or the sealing is ineffective.
For doors and windows with corners or connected forms, if the upper part of the connecting rod located at the corner or connected part is not sealed, it is easy for rainwater to leak from top to bottom into the room
However, in the production and processing of aluminum alloy doors and windows, the processing party usually uses a punch press to punch out several regular holes on the lower slide (which is the aluminum alloy with the lowest side facing the room and the outer side of the room) to prevent water from accumulating on the slide up the mountain. On both sides of the lower slide, a thick double-sided adhesive tape is applied to prevent water from flowing out of the gaps. Before assembly, the edges (two aluminum alloys on the left and right sides of the aluminum alloy frame) are sealed
