uPVC Door is a kind of building doors and windows commonly used in our families. Plastic-steel doors and windows occupy half of the market in the market. Plastic-steel doors and windows have become the standard installation configuration in many communities and buildings. However, does the quality of uPVC Door pass the customs, and what aspects should be checked during acceptance? Let me tell you!
1. The profile quality of uPVC Door
The appearance of the profile should be observed. The color should be bluish white, not white as people usually think. Pay attention to whether the color of the frame and sash forming the door and window is the same, whether the appearance is uniform, and whether the cavity distribution is reasonable. Calcium carbonate is usually added to the formula of plastic steel door and window profiles, and some manufacturers, in order to reduce costs, if too much is added, it will become calcified plastic. The surface of doors and windows made of this plastic lacks gloss and is slightly rough. Hard and brittle, it looks rough like a stone. A normal uPVC Door usually has a shiny surface and is very tough.
2. Reinforced steel of uPVC Door
According to national standards, there are different requirements for the wind pressure resistance of plastic steel doors and windows. The inner cavity of the frame and fan of the uPVC Door needs to be equipped with reinforced steel. According to the height, there are three kinds of reinforced steel with thickness of 1.2mm, 1.5mm and 2.0mm to ensure The robustness and longevity of the product. In order to reduce costs, some manufacturers do not install or install reinforced steel that does not meet the requirements.
Three, check the surface of doors and windows
The surface is neat and clean. This one of the uPVC Door installation acceptance standards is the most superficial. The surface of plastic steel doors and windows should be free of scratches, breakages and corners. Check to see if the doors, windows and glass are open, welded or broken during installation, and if the doors and windows are closed, whether they are not closed tightly or leaked.
Fourth, the gap and sealing of doors and windows
Check whether the fit gap between the various profiles is tight, whether the cuts at the mating parts are even, the height difference of the overlapping parts of the profiles, and so on. Generally, for plastic-steel doors, the main considerations are the gaps between door frames and sashes, door panel battens and door panel edging, various profile joints of shutters, sealing strips, etc.; also consider the gaps between door panels; the two door leaves are in the Whether it transmits light after closing, etc.
Similarly for uPVC Door, in addition to the assembly gap of various profiles to be assembled, it is also important to consider whether the sealing strip is uniform and firm. The interface gap should not be greater than 1mm, which reflects the sealing performance of the window. Plastic steel doors are usually used as inner doors of buildings, and the requirements for sealing are not so high. The smaller the gap value at the connection of various profiles, the tighter the fit, and the more exquisite the assembly process, which reflects the assembly level and the accuracy of the assembly tools.
5. Check whether steel is added inside the doors and windows
When closing the house, you can use iron absorption stones to check whether the uPVC Door is equipped with steel, whether there are anti-collision blocks at the bottom of all sliding doors and windows, and whether the length of the anti-collision blocks is sufficient.
Six, check whether it is safety glass
When inspecting the window glass, you must check whether safety glass is used, mainly to see if there is a 3C mark on the glass. You must know that safety glass must be used in some places, if it is on the 7th floor and above. Safety glass must be installed on the windows, and safety glass must be used for glass with an area greater than 1.5 square meters. In addition, safety glass must be used for balcony guardrail glass. These are directly related to the safety of occupancy, let alone careless.
Seven, check the error value
When closing the house, pay attention to check whether the installation error of the uPVC Door meets the standard. Ensure that the window frame is horizontal and vertical, and the height is consistent. Usually the diagonal length is within 2m, and the error is less than 3mm; if the diagonal length is greater than 2m, The error is less than 5mm. If the window height is within 2m, the verticality error should be less than 2mm; if the window height is greater than 2m, the error should be less than 3mm.
8. Check for water seepage
The inspection of plastic-steel doors and windows when closing the house must not ignore the water seepage. Pay attention to check whether there is water seepage near all the door and window frames to avoid affecting the convenience of life in the future.
9. Welding of uPVC Door
It depends on whether the welding place is even, whether there are cracks, whether the inner and outer corner joints are clean and beautiful, use a box ruler to measure the diagonal size of the plastic steel doors and windows, the diagonal size difference should not be more than 3mm, the diagonal difference The smaller the display, the finer the craftsmanship, which also facilitates installation.
Therefore, when checking and accepting uPVC Door, if any problems are found, you should consult with the developer in time and require refurbishment. You must check carefully during acceptance, because if there is a problem that is not found or ignored, it will affect the daily use after check-in. of.
