The main causes and solutions of door and window leakage
The main reasons for door and window leakage:
Design or structural defects of doors and Windows:
There is no drainage hole or the design of the drainage hole is unreasonable, resulting in rain water can not be discharged in time, accumulate in the cavity and may leak into the room through the sealing strip.
There is no middle rubber strip in the inner opening window or the middle rubber strip is ineffective, making rain easily enter the room through the gap.
Poor sealing performance:
The uneven profile of the door and window affects the close fit of the frame fan, resulting in the inability to completely close.
The quality of the rubber strip of the door and window is not good, and the problem of embrittlement and non-rebound may occur after a period of use, resulting in poor sealing.
During the installation of doors and Windows, the sealing work between the door frame, window frame and wall is not done well, such as waterproof glue is not evenly coated, and sealant is not done enough.
The low sealing grade and the insufficient number of sealing strips cause the window to be loosely sealed.
Hardware accessories problem:
The quality of hardware accessories of doors and Windows is not good, and rust and aging lead to poor window closure and poor sealing.
Material aging or deformation:
Aging of door and window materials, such as aging of rubber strips, will reduce the sealing performance.
The frame of the door and window is affected by external force for a long time and is easy to deform, resulting in reduced tightness.
The solution:
Replace or repair doors and Windows:
For older or defective doors and Windows, consider replacing new doors and Windows, and choose door and window materials with better sealing performance.
Repair or replace locally damaged doors and Windows, such as blocked drainage holes or aging rubber strips.
Check and replace the seal:
Regularly check whether the door and window seals are aging and damaged, and replace them in time if there is a problem.
Choose a good quality seal to ensure strong corrosion resistance, good weather resistance, long-term use of non-embrittlement, good resilience.
Adjusting doors and Windows:
For the deformation of the door and window frame, the sealing of the door and window can be enhanced by adjusting the position of the door and window frame.
Additional sealing measures:
Add sealing strips or rubber strips to the edges of doors and Windows to enhance the sealing performance.
For air leakage caused by installation problems, clean the gaps between window frames and walls and fill the gaps with cement and sand.
Care and maintenance:
Regular cleaning and maintenance of doors and Windows to keep them in good condition.
Avoid applying excessive external force on doors and Windows to prevent deformation or damage.
