In the summer, flies and mosquitoes began to harass everyone. To keep them out of the window and ensure ventilation, screens were the first weapon. So security screens, mosquito screens, dust screens, etc. have poured into the market. Although most windows can install a variety of screens, they are very skillful when selected. â—† screens have their advantages and disadvantages The reporter learned from the market that there are basically three kinds of screens on the market: fixed screens, screened screens, and invisible screens. But they have their merits, and consumers can choose their own needs. The fixed screens, as the name suggests, are fixed on the windows; the screens are open screens that can be opened or opened. The two kinds of screens are fixed and the structure is relatively simple, and it is easy to disassemble and disassemble. If it is necessary to clean, the screens can be removed and cleaned. Fixing the screens is a good option for owners who live at high levels and do not need to open screens. For large-sized homeowners who often need to deliver things from the windows, it is best to choose swing screens. Fixed-screen windows and flat screens are relatively cheap, ranging from RMB 110 to RMB 160/window. The invisible screen window is not “invisible†as everyone thinks. It refers to the screen window that the screen can be rewinded into the box. The frame is attached to the window frame and has the function of an ordinary screen window. When not in use, the screen automatically rewinds. In the yarn box, it does not occupy space and does not affect the appearance of the window. Therefore, it is called "invisible screen window". Compared with fixed screens and flat screens, this product is more aesthetically pleasing and more popular with consumers, but at a higher price, about 160 yuan/mm-280/mm. At the same time, the invisible screens “are not long-livedâ€. Lin Qiang Song pointed out that the invisible screens are usually placed on the outside of the windows. Under the irradiation of ultraviolet rays, the plastic parts are prone to aging. The reporter also noticed that most invisible screens have a warranty period of one year. â—† Do not be fooled by the concept Many screens on the market are known as mosquito screens, dust screens, and wind screens. In fact, the general screens have the above functions. However, people in the industry said that there are no major differences in whether or not screens promote “anti-mosquito†or “dust-proofâ€. Some invisible screens claim to be "dust-proof" and have "automatic cleaning function". A certain brand of invisible screens professionals introduced this kind of "dust-proof" actually means that the screen window itself does not stain the ash, and there are two tops in the box. When the gauze is rewinded into the box, the tops can brush the gauze so that the gauze can be “dust-proof†and “self-cleaningâ€. This is not the same concept as the “dust-proof house†that consumers understand. . The reporter also saw that many invisible screens also promoted wind protection, such as windproof grade 6 or windproof grade 8, etc. Insiders pointed out that windproof means that the wind cannot blow out the gauze. Lin Qiang Song believes that, as long as the installation is generally good, gauze has a wind function. Consumers can press the gauze by hand while shopping, and feel more self-conscious. It is best to compare several different windproof devices. â—† Pay attention to the difference between materials: The life span of screens has a lot to do with their quality. When selecting, the owner needs to consider various factors such as profiles, gauze, and accessories. 1. Profiles: The profiles of screens are divided into plastic and aluminum alloys. According to industry insiders, some of the so-called plastic steel screens used at present do not have steel liners. They are PVC profiles. The sun is easily deformed and its service life is short. Aluminum alloy profiles do not have this problem. A good aluminum alloy screen profile must be 0.7 mm or more, consumers can choose by hand by pressing, shake, feel the hardness of the profile, not soft enough. 2, gauze: gauze material also has a lot of, glass fiber material has a certain degree of flame retardant effect, anti-aging ability, strong weather resistance, and physical properties change is not, at present most of the screens use this material; stainless steel With the characteristics of plastic deformation, once the deformation can not be restored, and the hole is larger, the mosquito-proof effect is not good, the screen window will have burrs after shearing, which will easily cause accidental damage; the plastic material does not have weather resistance, and is easy to be aged, generally not recommended . 3, Accessories: If you choose invisible screens, it is best to check whether it has a positive force adjustment device. Since the invisible screen window needs to be continuously pulled out and rolled up, the spring tends to be weak, which is an important factor affecting its quality. The screens with frontal force adjustment devices can be adjusted when the springs are in a weak state. Otherwise, they can only be adjusted or replaced by the manufacturers, which will affect the service life of the products. In addition, you need to look at the opening device when selecting, that is, whether the hooks are easy to use and strong.
