At present, there are two main types of invisible plastic window products, i.e. aluminum alloy window and invisible plastic window. The main market of plastic steel profile is engineering, and its service life is about 1 year. Aluminum alloy profile market is divided into engineering and home decoration. The service life of Engineering screen window is about 2 years, and that of home decoration screen window is about 5 years. Note: (the service life is not the overall damage of the screen, only the local damage.)
Suggestion: the owner should take a look at the strength of aluminum alloy when selecting enough yarn doors and windows, because there are great differences in the thickness of profiles. The thinnest part of Shanghai liefan's latest window screen profile is 1.2mm
The difference of invisible screen bearing: the bearing is divided into domestic bearing and imported bearing.
Suggestion: domestic bearing is open type bearing, if it enters dust, it will not run smoothly. It is better to choose imported fully enclosed silent bearing.
3 selection of invisible screen spring: the spring is divided into window spring and door spring.
Suggestion: because it is an invisible accessory, pull the screen door by hand to see the effect of rewinding. If the rewinding is too slow, it may be the spring for your window.
The difference of invisible screen mesh: the gauze is divided into glass fiber mesh and polyester coated chemical fiber mesh.
Suggestion: fiberglass mesh is mainly used in engineering, and a small amount of home decoration. The service life is about 2 years for external screen and 3 years for interior screen. Polyester coated chemical fiber net is mainly used for home decoration, and the service life is about 7 to 8 years. The best choice of polyester coated chemical fiber mesh
5 invisible screen design: because the height of the window is too high and the width is too narrow, it is inconvenient for you to use the screen window. For example, if it is too high to pull down, the yarn mesh will come out as soon as the wind blows, and the magnetic strip can't absorb and roll back automatically.
Suggestion: if the window height of your home is more than 1 m2. When you are ready to order, ask the designer to design the side pull style. It is not only portable, but also can't cause the above reasons. Will also increase the service life of invisible screen window. Because the distance of replacing the screen window is relatively short, so the pressure on the screen accessories is relieved. Basically no fault will be caused during the warranty period.
