Aluminum window extrusions and doors can encounter inevitable issues in daily use, such as water leaks, especially during heavy rains. Many homeowners may sense something amiss with their homes but struggle to pinpoint the source of water infiltration.


1.Common Issues:

·Leaks between the wall and aluminum profile frame.

·Puddles forming in sliding window tracks and seeping into the room.

2.Causes:

·Improper materials used between aluminum window frame sections and walls.

·Insufficient adhesive between walls and window frames.

·Design flaws, such as inadequate sealing of sashes and frames.

·Incorrect installation of sealing strips and rubbers, resulting in water leaks from sashes.

·Lack of designed draining holes.


Water and air-tightness are paramount for product quality. Based on practical experience, attention to the following points can help prevent leaks:


1.Install drip lines along the inward shape of windows to prevent capillarity.

2.Apply asphalt around windows, extending 300mm to the frames, after completing water-proof painting on the walls.

3.Use concrete mixed with water-proof agents to prevent honeycombing, which can lead to water leakage through the holes.

4.Seal connections between window frames and other materials with glue.

5.Install a canopy above windows to divert raindrops away from the room.

6.Design window sills with a downward slope towards the outside, and seal with outward-facing glue.

7.For single-pane glass, design draining holes a quarter of the way up from the bottom and to the side.

8.Ensure tight sealing of connections around frames during construction.


By addressing these factors diligently, homeowners can significantly reduce the risk of water leaks and maintain the integrity of their aluminum windows and doors.
