Plastic steel doors and windows are rapidly replacing steel windows and aluminum alloy windows with their excellent performance and beautiful appearance, and gradually become the new favorite of decoration. However, plastic steel doors and windows are still a new type of building materials in China, and most people are still relatively new to it. So, how to distinguish the advantages and disadvantages of plastic steel doors and windows?
Understand the UPVC profiles selected for plastic steel doors and windows
UPVC profiles are the decisive factor for the quality and grade of plastic steel doors and windows. Many people think that the plastic steel windows are all the same white. In fact, the high-grade UPVC profiles should be rationally designed multi-cavity, wall thickness, anti-aging and anti-UV in the formula. Auxiliary, from the appearance, it should be smooth surface, white and blue, such color anti-aging performance is good, in the outdoor wind and sun for 30 or 50 years will not aging, discoloration, deformation; and low-end profiles It is yellow in the white, this color has poor sun protection ability. After a few years, it will become yellower until it ages, deforms and cracks. The reason is that the profile formula contains too much calcium. You can ask the manufacturer to compare the profiles of different profiles and compare them with each other.
Look at the glass and hardware used for doors and windows
The glass should be flat, water-free, and firmly installed. It is not in direct contact with the plastic profile, and there is a sealing bead to close the gap. Glass glue cannot be used. In the case of double glass interlayers, there should be no dust or moisture in the interlayer. The high-end doors and windows have complete hardware, correct position, firm installation and flexible use. They are all made of metal. Their inner strength and appearance directly affect the performance of doors and windows. The plastic hardware used in the middle and low-grade plastic steel has great hidden dangers in its quality and longevity.
Look at the assembly quality of doors and windows
The surface of the door and window should be smooth and flat without breaking welds. Special steel lining should be embedded in the door and window frame and fan profile. The sealing strip should be flat, no curling, no grooving, and the strip is odorless. The doors and windows are all integral, screwless, the switch components are tightly closed, and the switch is flexible. When the door and window are closed, there is no gap between the fan and the frame; when the push-pull is opened, it slides freely, the sound is soft, and no dust falls off.
The most important thing is to buy plastic steel doors and windows made of professional equipment in the factory floor, and check whether the door and window manufacturers have a production license issued by the construction committee. Do not buy cheap plastic steel doors and windows, plastic steel windows produced by street workshops, the quality and credibility are not guaranteed.
The last thing to emphasize is that everyone should choose a plastic-steel window to shop around. If you have the conditions, it is best to look at the factory window. However, the comparison of the three is not a simple "price ratio of three" because the door and window products are not like home appliances, as long as the brand, model, the lowest price. There are many kinds of plastic steel door and window profiles. Even if the same profiles are different in processing level, installation level and after-sales service due to different steel linings, accessories and hardware, the quality of doors and windows will be greatly different.
