Things to Know About Door and Window Acceptance

Whether the windows are securely installed is a primary concern during inspection. When conducting the acceptance process, pay close attention to the window material, specifications, dimensions, and thickness. The material and thickness of the window glass are critical indicators of safety. Additionally, check the window’s decorative design and ensure that the sash operates smoothly and conveniently, while also verifying how well it seals.

　　First, strength acceptance testing of the windows
　　Whether the windows are securely installed is a primary concern during inspection. When conducting the验收, pay close attention to the window material, specifications, dimensions, and thickness. The material and thickness of the window glass are critical indicators of safety. Additionally, check the window’s decorative design and ensure that the sash operates smoothly and conveniently, while also verifying how well it seals.
　　Second, acceptance of the functional performance of the windows
　　When inspecting the functional performance of the windows, make sure to manually slide open and close the casement windows yourself to check whether they operate smoothly. Additionally, the window surfaces must be smooth and free of significant scratches, and the profiles should show no signs of cracking or breakage before approval.
　　Third, hardware inspection of the windows
　　The hardware components of a window are crucial for ensuring its proper functionality. Therefore, during inspection, make sure all the window accessories are present, the installation positions are correct and secure, and the window frames and sashes are perfectly vertical—there should be no bending or warping. Additionally, check whether the drainage holes are fully open; if they’re blocked, water could accumulate and seep into the window’s uneven or recessed areas.
　　Fourth, acceptance testing of window sealing performance
　　In autumn and spring, the winds can be quite strong, so it’s best to keep windows closed during nighttime rest. If the windows aren’t properly sealed, drafts can sneak in, disrupting your sleep. That’s why it’s crucial to thoroughly check the window seals during inspection—when closed, there shouldn’t be any noticeable gaps between the sash and frame or between sashes themselves. Additionally, the sealing strips must remain firmly in place without loosening, detaching, or peeking out visibly.
　　Fifth, acceptance of window glass
　　The largest component of a window is the glass, which must not only be clean and transparent but also free from any cracks or damage. Additionally, the space between the two panes of glass should remain free of dust and moisture, while the spacer bars must be evenly spaced.
　　Those are the acceptance criteria for windows—so if you’re currently renovating your home, you can use these points to check whether your window installation meets the standards.
