Although the leakage of aluminum alloy doors and windows is partly a quality problem in the process of making doors and windows, it is only one of the reasons for the leakage of aluminum alloy doors and windows, however, most of them are caused by rainwater leakage caused by inadequate handling during installation.
If you encounter the problem of leaking aluminum alloy doors and windows, you have to make a preliminary judgment and then decide whether to choose maintenance or replacement. After all, the price you have to pay for maintenance and replacement of doors and windows is much different!
The main causes of rainwater leakage of aluminum doors and windows can be divided into four categories:
1. Caused by defects in the structure of doors and windows during the design process
2. Failure to meet quality requirements during processing and installation
3. Unqualified materials and hardware
4. Caused by improper sealing treatment of the connecting part with the wall of the opening
in addition to the water leakage caused by the problems of doors and windows, doors and windows must be replaced.
Others are water leakage caused by deviation or error during installation,
the most common situations are as follows:
1. The gap between the door and window frame and the wall does not need sealant sealing or the process is rough. No groove is left between the frame and the Wall foot body according to regulations. No sealant is applied or the dust on the groove surface is not cleaned up before gluing, as a result, this place has become a weak link in waterproofing.
2. The gap at the joint of frame material is not sealed by sealant, which causes water seepage at the joint.
3. The rubber sealing strip or water-blocking brush strip for installing glass is not in place or falls off.
4. There is no gap between the frame and the wall or the embedded material does not meet the requirements, the filling joint is not dense, and the contact surface between the frame and the wall is not anti-corrosion treatment. Some even directly use cement mortar to fill joints, resulting in leakage caused by cracks caused by shrinkage of cement mortar. At the same time, due to the corrosion of cement on aluminum alloy frame, the durability of doors and windows is affected.
5. No drain hole is left or the sealant is too thick to block the drain hole, causing the rainwater in the push-pull groove of the lower frame not to be removed in time, resulting in rainwater infiltration.
6. The material selection of the lower frame is too small, the section size does not conform to the standard, and it is not raised according to the regulations. Some even bury the window frame into the plastering layer of the window sill, causing the rain to easily penetrate into the room.
7. Drip lines or olecranon are not customized at the upper part of the window. The slope of the window sill is too small or there is water flooding, which is also one of the main reasons for window seepage at present.
8. Before the installation of doors and windows, the verticality of the front side will not be corrected, causing the window frame to tilt inward and seepage.
9. For doors and windows with corner or connected form, the upper part of the connecting rod of corner or connected part is not blocked, which is easy to cause leakage of rainwater to enter the room from top to bottom.
So, how to solve the leakage of aluminum alloy doors and windows?
I. The design and quality problems of doors and windows lead to water leakage
there are problems in the design of doors and windows, or there are problems in the quality of doors and windows at all. It is recommended to replace doors and windows quickly to reduce harm!
II. Water leakage caused by failure to meet the requirements during aluminum alloy installation
check the gap size and verticality between the drain hole, window frame and the wall. If necessary, workers can remove the doors and windows and reinstall them once.
Not only should the airtight and watertight performance of doors and windows be considered when purchasing doors and windows, but also the installation of doors and windows should be considered! The installation is not good, and even high-end doors and windows can only be furnishings! Therefore, after the doors and windows are decorated, acceptance is also a very important step!
