Invisible screens are one of the many varieties of windows, and they are now one of the choices for fashion home furnishings. Invisible screens are the screens that the screen can rewind into the screen. The frame is attached to the window frame. It has the function of common screens. When not in use, the screen automatically rewinds into the box. It does not occupy space and does not affect the windows. Beautiful, so called "invisible." However, after the screen is opened, the screen can still be seen. The role of invisible screens is mainly dust and ventilation. When we choose invisible screens, we need to pay attention to some common sense: 1) Look at the color of invisible screens Because the colors of doors and windows are complex, we should pay attention to whether the quality of the inspected colors after the purchase of invisible screens is faded or dropped. 2) Understand the profiles of invisible screens The market is now mainly divided into two types of invisible screens, aluminum alloy and steel. The main market for invisible screens of steel profiles is engineering. The stealth screen window of aluminum alloy profiles is divided into two aspects: engineering and home improvement. The warranty period of the invisible screens of the project is relatively short, and the warranty period of invisible screens for home improvement will be longer. Look at the strength of the aluminum alloy when choosing enough invisible screens because there is a big difference in the thickness of the profile. 3) Look at the invisible screen mesh material The invisible screen mesh is divided into glass fiber mesh and polyester coated chemical fiber mesh. Glass fiber mesh is mainly used for engineering purposes, and a small amount of home improvement is used. Polyester-coated chemical fiber webs are mainly used for home decoration, and their use in some areas has been banned. The main reason is that polyester yarns have high strength but are not fireproof. 4) The design of invisible screens is inconvenient when you use invisible screens because the current window height is too high and the width is too narrow. For example, too high to pull down is too strenuous, the gauze is blown out by the wind, and there is magnetic screen window can not suck automatically rolled up and so on. If your home window is more than 1 meter 2 wide. When you are ready to order, designers are required to design the side pull style. Not only is it light and it does not cause the above reasons. It will also increase the service life of screens. Because the screen window is pulled out relatively short, the screen accessories are relieved. Basically, it will not cause any trouble during the warranty period, but it will increase the cost of screens, so the price will be higher. The windproof method chooses the brush or the piece type windproof as far as possible, has solved the gauze net easy to come out the difficult problem. 5) The difference between invisible screen bearings The bearings of invisible screen windows are divided into domestic and imported bearings. Domestic bearings are open bearings, if you enter the dust will not work smoothly. It is best to buy imported fully enclosed silent bearings. 6) Invisible screen window cleaning Invisible screen window has "automatic cleaning function" means that the invisible screen window itself does not pick up dust, put two pieces of top in the box, and when the screen is rolled back to the box, it can brush the screen and make the yarn The network achieved "dust-proof" and "self-cleaning" effects.
