How to deal with the air leakage property at the entrance door

1. Clean the gap between the window frame and door cover and the wall, then fill it with styrofoam, then fill the gap with cement and sand, and finally repair it.

2. If the installation of workers is not in place, resulting in air leakage in doors and windows, you can find a dealer or manufacturer to reinstall.

3. If there is no problem with the quality of the door, but the sealing strip is aging, it is necessary to rearrange the sealing strip and re-inject sealant between the door frame and the wall to make the sealing effect better and block the external seam, then there will be no air leakage problem.

4. If the gap is small, you can put a paper pad in the gap. If the air leakage gap in the door is large, a layer of plastic steel window can be added to the inside of the window at this time.
