Fourth, check whether there are ****s in the information between the frame and the wall material

During the installation and construction of aluminum alloy doors and windows, many Chinese workers did not work on the sealing system between the door frame, window frame and the wall due to rushing work or cutting corners.

Five, check whether the hardware is locked tightly

The quality of aluminum alloy and door and window hardware is also closely related to the sealing performance, especially when opening flat windows directly, it relies on the drive of the hardware for analysis and sealing.
