It should be said that people have long realized that the screen window is used to prevent mosquitoes from invading, so in the early days of building materials and doors and windows industries, a fixed sliding frame with track configuration was added at the same time when installing doors and windows to alleviate mosquitoes from entering the room to some extent. With the promotion of environmental protection and simple home decoration, people realize that the service life of screen window will be prolonged when it is not used in winter, so folding screen window came out and was once popular, because the screen window can be folded together, making people invisible, as the name suggests. Lotus rolling screen window is a new type of screen window developed on the basis of folding screen window. Replacing the folding screen window is also an inevitable trend of development, because the screen window is completely open and flat, and the screen window can't be seen in the distance, which is called "invisibility", and the screen window is completely rolled into the pipe. It is also "invisible", so the rolling screen window has two meanings of "invisible", which is called invisible screen window.
Definitions of terms-Invisible screens
Invisible screen window is a kind of screen window which can automatically rewind gauze. Mainly used for ventilation and mosquito prevention. The window frame is tightly attached to the window frame. Pull out the gauze when it is used, and the gauze will automatically roll back to the gauze box when it is not used. Does not occupy space, but also has strong sealing performance. Coordinate with high-end home improvement.
At present, there are many screens and screens on the market, such as invisible screens, upper and lower shutter screens, single shutter screens, double shutter screens, push-pull screens, folding screens and magnetic screens. And there are many places where you can buy them, such as building materials supermarkets, screen manufacturers and small shops near your home. Classification sounds a lot, but it is actually relatively simple. According to the function, it can be divided into: single screen window (fixed, already traditional) and now popular rolling screen window (also known as invisible screen window). Invisible screen window has the characteristics of simple structure, convenient installation and use and easy maintenance. Whether it's up and down, left and right, or window pull, door pull, the name is different. Its principle is similar to that of a rolling door. There is a screen window that is pulled up and down, left and right or pulled from the middle in a frame, and there is a guide rail in the frame.
However, the quality of screens on the market is mixed, and how to choose screens and screens with good quality and appropriate prices is very particular. Take the free wind invisible screen window as an example!
Introduction 1? Yarn selection
The quality of screen window is first of all screen window (gauze). There are domestic and imported gauze. Most of the imports are interwoven gauze; Made in China is glass fiber mesh, and some are plastic. Imported high-quality gauze can not deform through tens of thousands of times of push-pull friction; Domestic glass fiber can only withstand thousands of times; Because of the material, plastic screen window is easy to expand with heat and contract with cold, and the probability of deformation is very high. Therefore, priority should be given to imported gauze.
Pay attention to two points when buying:
A, you see, the quality of window screen depends on whether its mesh is uniform or not. For example, imported high-quality anti-mosquito yarn has 16× 18 meshes per square inch (25.4 square centimeters), which is slightly rectangular, with neat shape and no size; In addition, see whether the yarn thickness is uniform, thick or thin.
B, touch, touch the window screen with your hand, it feels quite scraped, like it is scalded, and the quality is good; However, the domestic glass fiber window is soft and does not collapse.
Introduction 2? structure
The structure of the screen window is also an important point of its price difference.
The shutter screen window can be opened for easy use. But in addition to opening freely, its core is good sealing performance. When the gauze car is closed, it is completely closed and there can be no gaps. Otherwise, what's the use of mosquitoes coming in?
Therefore, a good roller shutter screen window and screen window are bound with nylon (pvc)? .
Wherein a positioning rod is arranged in the guide rail. Should be free to open, seal and resist strong winds.
Anti-strong wind experiment The anti-strong wind experiment gauze can withstand the pressure of about 10 kg without running! ?
However, the shutter that cuts corners often saves a process. The tops are placed in the guide rails on both sides, and the screens are directly inserted. When the wind blows, the screen window is blown away, and natural mosquitoes enter through the gap, which does not play a role in releasing mosquitoes.
So when you buy it, you should pay attention to pressing the gauze by hand to see if the window screen will come out.
Introduction 3? equipment
The so-called device is that there is a box at one end of the roller shutter screen. When mosquito prevention is needed, gently pull the screen window to the end, bite the box and suck it, and the screen window is completely sealed; Pull up the window screen, and the window screen will be involved in the window box. As shown on the right:?
Introduction 4? design
The frame of aluminum alloy color rolling screen window is made of sprayed aluminum alloy, which is called color aluminum. Generally, there are many colors to choose from, and you can choose a color similar to the color of your own window.
skill
price
The prices of shutter doors and screens vary greatly. In building materials supermarkets, the price is mostly near 200 yuan, 300 yuan and even 1000 yuan per meter. Factory direct sales, because it saves the cost of sales, the quality is similar, for example, more than 200 yuan, as long as 100 yuan; Some small shops, because of differences in raw materials, technology, etc. The price is also around tens of yuan.
service
The shutter doors are all customized, measuring the area at the door, designing whether to push or move the window, whether to install it outside or inside, whether it is half-open or fully open, and so on. Pay attention to after-sales service and have a warranty period. After the warranty period, there should be a certain maintenance period, such as paying for the replacement of broken parts.
