1. Carefully inspect the junction between the window frame and the wall. If the junction is not properly sealed, it is easy for dust and water to enter, making it difficult to maintain during later use. The junction should be flat, straight, and firmly connected. In addition, when selecting door and window sealing strips, rubber should be used.
2. Observing the rubber sealing strip between the glass and the window frame, it should be kept flat and free of grooves. If not handled properly by the construction personnel, it will not only affect the sealing effect, but also affect the appearance of the window.
3. Check the sealing strip of the window sash. Some homeowners may not be very familiar with the sealing strip of the window sash, which is usually embedded at the contact between the window sash and the window frame.
4. To check the sealing quality of the entire window, the general operation is to close the window and check if the sealing strip is in a compressed state. If it is not, it indicates poor sealing, otherwise it indicates good sealing.
