Inspecting Appearance Quality

During acceptance, first examine the appearance quality of doors and windows. Check whether surfaces are smooth and even, and look for defects such asscratches, dents, or discoloration. Verify that glass is securely installed with no signs of loosening or cracking. Ensure sealing strips and caulking are smooth and continuous, with no gaps or bubbles. If appearance issues are found, promptly request installers to rectify them.

Testing Functional Performance

Evaluating the functional performance of doors and windows is a critical part of acceptance. Repeatedly open and close each door or window panel to verify smooth operation, secure closure, and absence of abnormal noises. For doors and windows equipped with locks, test whether the lock mechanism operates smoothly and whether the locking points engage accurately with the lock housing. Additionally, perform simple sealing tests: with the door or window closed, place your hand near the gap to detect noticeable airflow, or insert a thin sheet of paper into the gap to see if it can be easily pulled out. If the paper moves freely, it indicates poor sealing and requires adjustment.

Verifying Safety Performance

Ensuring doors and windows meet safety requirements is equally crucial. Inspect their wind pressure resistance, paying particular attention to units in high-rise buildings or windy locations to confirm they can withstand significant wind forces. Refer to product manuals and relevant test reports to determine their wind resistance rating. Simultaneously, evaluate burglary resistance by examining lock quality and security features to ensure effective protection against unauthorized entry.
