Most people knew about the performance of Plastic Window Profile before the renovation, so they chose plastic steel windows. But after installation, it was found that the windows were leaking. What are the reasons for the air leakage of plastic steel windows? How to solve it?
Reasons for Air Leakage in Plastic Window Profile:
There may be four reasons for the air leakage phenomenon in Plastic Window Profile: the window gap is too large, the larger the gap, the more serious the air leakage; the hardware equipment is not locked tightly, the window sash is off corner, and the window is deformed.
How to solve the phenomenon of air leakage:
1. Kraft paper repair:
When we are repairing, we can use kraft paper for enhanced protection. It is good to keep it airtight when pasting and repairing, so that the indoor temperature can be maintained.
2. Glue to seal up the window gaps
If the window leaks because there is a gap between the window frame and the wall, you need to glue the window gap. If the gap is large, styrofoam needs to be filled and then treated with sealant.
3. Seal the diagonal corners of the window molding
The window frame of the plastic steel window has a drainage system, and the outer drainage hole is connected with the cavity where the hollow glass is placed, and the cold air will enter the glass cavity along the drainage hole. Wind leakage from windows may also be caused by air leakage at the opposite corners of the window moldings. At this time, sealant should be used to seal at the diagonal corners of the bead.
4. Adjust the installation of hardware accessories
Some plastic-steel windows are installed without hardware accessories, and the hardware does not achieve a good locking effect. At this time, the hardware lock needs to be adjusted. Even if the window leaks too much, new hardware accessories need to be replaced.
5. Replace the aging tape
If the window is leaking due to the aging of the window tape, you need to replace it with a new one.
6. Correct window deformation
It is well known that Plastic Window Profile is easy to deform. If the window leaks due to the deformation of the window, the window needs to be corrected. In addition, severely deformed plastic-steel windows need to be replaced.
