3. Glass Sealing Strips: The sealing strips should make smooth, even contact with both the glass and the glass grooves, without any curling or loosening from the groove.
1. Window surfaces: The window frames must be clean, smooth, and even, with no scratches or dents on the main surfaces, and the profiles should show no signs of welding cracks or fractures.
2. Hardware Components: All hardware components must be complete, correctly positioned, securely installed, and operate smoothly, ensuring they fully perform their intended functions.
3. Glass Sealing Strips: The sealing strips should make smooth, even contact with both the glass and the glass grooves, without any curling or coming loose from the槽口.
4. Sealing Quality: When the doors and windows are partially closed, there should be no noticeable gaps between the sash and the frame, and the sealing strips on the sealing surface must be in a compressed state.
5. Glass: The glass should be smooth and securely installed, with no signs of looseness. Single-layer glass must not come into direct contact with the profiles. Both inner and outer surfaces of double-layer glass must be clean, and there should be no dust or moisture inside the glass interlayer. Additionally, the spacer strips must remain flat and free from warping.
6. Press Strip: The press strip with sealing strips must be fully and tightly pressed against the glass. There should be no noticeable gaps at the joint between the press strip and the profile, and the joint gap should be no more than 1 millimeter.
7. Spacer Bars: The spacer bars must be securely connected to the window frame and tightly sealed with jointing compound. They should remain stable without any wobbling, with screw spacing no greater than 600 millimeters. Additionally, the reinforced steel liners at both ends must be firmly anchored to the opening.
8. Switch components: Casement, sliding, or pivoting windows must all close tightly.
9. Frame-to-wall connection: The window frame should be perfectly horizontal and vertical, with consistent height across all frames. The spacing between fixing strips must be no more than 600 millimeters. The frame must be securely attached to the wall, and any gaps should be fully filled with an elastic material. Finally, seal the surface joints thoroughly with caulk, ensuring there are no cracks.
10. Drainage Holes: Ensure the drainage holes are positioned correctly and remain unobstructed.
How to assess window quality
Currently, the quality of windows produced on the market varies widely. So, how can you tell the good ones from the bad?
It can primarily be observed from three aspects:
1. From the perspective of profiles, surface finish, the rationality of cavity structure, profile wall thickness, and the appropriateness of profile fit are all key criteria for evaluating the quality of a profile.
2. From the perspective of hardware accessories, their quality can be primarily assessed by evaluating flexibility, sealing performance, wear resistance, and corrosion resistance. When it comes to the accessories themselves, special attention should be paid to the reinforcing steel embedded within the profile cavities—high-quality reinforcing steel should be galvanized A3-grade steel with a wall thickness of at least 1.2 mm. Unfortunately, some manufacturers nowadays often cut corners on the reinforcing steel to reduce costs and attract customers, ultimately deceiving consumers into making poor choices.
3. From the perspective of manufacturing processes, the quality of windows and doors largely depends on the excellence of their appearance, the precision of their dimensions, the strength of their corners, and the appropriate compatibility of the hardware components used.
