People's requirements for doors and windows have gradually changed from the traditional wind shelter and rain shelter to the present high performance, good-looking and high cost performance.
Disadvantages of triple sliding door:
1. The price is relatively expensive, and the cost is mainly on hardware. Wall cupboard doors have high requirements on track hardware. For example, the price of rail doors with super house frame in my home is about 1200/square meters on the market, however, the two fans bought on Taobao at I am have a total of 6,000 (excluding installation) and need to have sufficient control over the size and workmanship. If you are not professional, don't try it easily, if it is finished, it will be troublesome if it cannot be installed.
2. The tightness is not as good as that of the track door, because the ceiling door does not touch the ground and there will be gaps, which will affect the air conditioning effect but not very large.
3. High construction technology requirements.
4. The service life and maintenance comfort level are not as good as the track door. The rail door is not completely unserviceable, but relatively troublesome. I saw someone saying that the hanging rail door would shake, in fact, it was because there was a roller on the ground that limited shaking was not installed properly. After installation, the shaking will be greatly reduced.
5. The effect of constant temperature is relatively bad, but its overall performance is relatively reliable.
6. The quality of pulley and slide rail is unreliable, and problems such as deformation of door panel, poor push and pull, and severe noise occur from time to time.
