Ensure that the sealing of UPVC doors and windows is good and need to be paid attention to

First of all, when installing, make sure that the gap between the door, window and wall is appropriate, and use special sealant or sealing strips to fill it to avoid air leakage, water leakage and other problems. These sealing materials should have excellent weather resistance and aging resistance to ensure long-term use.
Secondly, the hardware of doors and windows is also a key factor affecting sealing. Choose high-quality hardware, such as handles, locks, etc., and make sure they are securely installed and can close doors and windows tightly to prevent the intrusion of outside air and moisture.
In addition, for push-pull UPVC doors and windows, attention needs to be paid to the installation and adjustment of slide rails and pulleys. Make sure the slide rails are straight and the pulleys slide smoothly to reduce friction and resistance during the opening and closing of doors and windows, thereby improving sealing performance.
In daily use, you also need to pay attention to the care and maintenance of doors and windows. Clean door and window surfaces regularly to avoid accumulation of dirt and dust to maintain good sealing performance. At the same time, avoid hitting the doors and windows with hard objects to avoid damaging the seals or causing the doors and windows to deform.
Finally, if the sealing performance of doors and windows is found to be reduced during use, such as air leakage, water leakage, etc., they should be inspected and repaired in time. You can ask professional door and window maintenance personnel to inspect and repair the door and window to ensure that the sealing performance of the door and window is restored in time.
