Solve common leakage problems of doors and windows
1. Water seepage at the junction of the door and window frame and the surrounding wall. This may be because there are bubbles and cracks in the sealant between the door and window frame and the wall of the door and window. For some doors and windows that are glued in winter, the sealant loses its adhesive force, and the seal is not tight and leaks.
Solution: The reason for door and window sealant cracking may be that the sealant is not used within the validity period, and the sealant has poor resistance to joint displacement cracking. Therefore, it is recommended to use sealant with good brand and reliable quality; it is also possible that a large number of bubbles formed during the sizing process lead to cracking. Attention should be paid during construction.
2. The seal between door & window profile and glass is not tight. Doors and windows adopt PVC sealing strips, which shrink, age and break for a long time, resulting in water seepage of doors and windows; Or if the sealing strips are not installed properly, they may also cause water seepage if they are uneven or bulging.
Solution: replace the sealing strip, remember not to choose PVC material, you can choose EPDM or TPE, anti-aging, corrosion resistance, high temperature does not expand, low temperature does not break, long service life. In addition, professional personnel can be invited to install it during the installation process, and timely check and replace it during the use process.
3. The joint of the profile causes water seepage, such as the four corners of the door and window, and the connecting part of the middle joint. This is because there is no tight joint between the profile and the profile during connection, resulting in water seepage.
Solution: generally, it is difficult to make the connection between doors and windows tightly fit, so now manufacturers all adopt glue injection technology, and waterproof adhesive will be added to the gap outside, so the rain will not seep in. For doors and windows that have been installed, only waterproof adhesive can be applied to the gap to temporarily solve the problem of water leakage between doors and windows.
4. When it rains, the strong wind causes the rain to pour back. Some doors and windows drainage system is to put a drainage hole on the outside of the doors and windows, and the water that seeps in directly flows out along the drainage hole, but if there is a strong wind, the rain cannot be discharged, because the wind blows from the bottom to the top, the rain will penetrate into the room for a long time.
Solution: Now New
broken bridge aluminum doors and windows it adopts stepped hidden drainage to prevent rainwater from pouring back.
5. The hardware is deformed, and the doors and windows are not tightly closed, resulting in water seepage of doors and windows. Especially casement window, it depends on the actuator of hardware to seal. If the quality of the actuator is not good, it is easy to seep water from the edge of the Casement.
Solution: Find a professional to debug the hardware, but this method can only be managed for a period of time, so don't choose inferior and cheap hardware to save money when buying doors and windows, if there is a problem later, it will cost more than good.
