Doors and windows are essential supplies in our daily life. What if there is air leakage in doors and windows? Let's first take a look at the main causes of air leakage between doors and windows.

01. Leakage caused by loose and deformed windows
loosening between Windows and borders is one of the most common causes of water leakage. On the one hand, when the window is closed, it will produce resonance vibration. After a long time, the gap between the window and the wall will become larger and larger; On the other hand, it is caused by the poor quality of the window, which is insufficient rigidity, it is easy to deform, and the mortar layer beside the window frame will crack and fall off soon after use, thus causing leakage.
02. Aging and shedding of adhesive strips
sealant strip is installed on the door and window frame, fan and glass. Relying on its contact elasticity function, it closely connects the profiles, hardware and glass of doors and windows into a whole. Poor quality rubber strip has poor aging resistance. After long-term exposure to the Sun, the rubber strip becomes hard after aging, loses elasticity, and is easy to fall off. It not only has poor sealing performance, but also can't stop water, it will also cause potential safety hazards due to loose glass.
03. Leakage caused by poor drainage of window slot drainage holes
some Windows may not have drainage holes, especially sliding window. All the rainwater accumulated in the pushing and pulling frame slot cannot be discharged. When it is full, it seeps into the house; Or I didn't pay attention to it when pasting tiles on the outer window sill, the drainage hole was blocked, and all the rainwater in the pushing and pulling frame tank leaked into the wall, causing water leakage.
In addition, the drainage hole may be blocked by sundries after being used for a long time, resulting in water flow not being discharged in time.
How to solve the leakage of doors and windows?
01. Re-seal the gap

for the gap between the outer window frame and the window sill, it is better to clear the original seal, fill in the weather-resistant silicon sealant for sealing, and then use cement mortar to block and do waterproof treatment.
02. Strictly control the quality of good materials

if the leakage is caused by the quality problem of the window itself, the window needs to be directly repaired or replaced. The quality of the purchased window frame, Casement, sealing strip, etc. should be passed. At the same time, the waterproof sealing material used should have material quality certification documents to ensure that the material quality meets the requirements. Do not choose inferior sealing materials.
If the rubber strip is aging, we can replace the sealing strip by ourselves. It is better to use EPDM strip, or the rubber and plastic strip with slightly worse quality is also OK; If we can't operate it by ourselves, it won't cost too much to find professional workers to change it at home.
03. Keep the window Rhone unblocked

in view of the leakage caused by window frame Rhone blockage, the problem can be solved by keeping the Rhone unobstructed. If there is a problem with the position of the drain hole, close the original hole and re-open the hole.
Finally, in addition to the problem of air leakage and water leakage, we 'd better have regular maintenance of the doors and windows at home.
