At first glance, there is nothing unusual about invisible screens. Isn't it a box on the door and window frame? Actually it is not. The profile wall thickness of single-screen windows is very large, ranging from 0.4 mm to 1.2 mm. The better screens are generally 0.8-1.0 mm, and the screens of this thickness are relatively strong. The screens sold by some manufacturers or vendors near the community have a thickness of about 0.5-0.7 mm. The hand feel is poor and soft. It is difficult to see with the naked eye. It should be measured with professional tools or compared with several household hands. That is, the choice is relatively thicker.
The aluminum used in the screens is also very particular. The poor quality is all made of aluminum alloy frame made of waste recycling. The color of this kind of frame is poor, the sunshine is long and easy to peel off, and the price is several thousand yuan better than the quality per ton. Even if it is more than 10,000 yuan, the cost gap is very large. Therefore, the market price of screens varies from 50 yuan / square meter to 300 yuan / square meter, the price gap is very large.
The installation of screens is often the last step in the renovation. Many owners have spent a lot of money in the early renovation process, and some may exceed their own budget, so they are often reluctant to spend big money on the screens. This is the most wrong. of. In the era of SARS and swine flu, the Ministry of Health has been propagating to open the window to breathe fresh air and less air conditioning. This means that if the whole family has a healthy environment, screens must be used, and the screens are more important than air conditioners. Therefore, some owners must be reminded to install a good screen to give the whole family a healthy environment.
