The answer is OK. Can be replaced with three rails. The original track does not need to be moved, and it is OK to install another set of monorail with the same material shape, but the original two doors can only be reduced, and another one is needed.
1. Three sliding doors need at least two tracks; If they are two tracks, only one door can be opened, that is, one third of the total width of the door; If they are three tracks, two doors can be opened, that is, 2/3 of the total width of the door;
2. Sliding doors are framed, and there is no requirement for gate stack, walls, etc. Just fix the door frame;
3. If you need to mute, purchase mute Pulley. It is best that the track and mute pulley are matched;
4. If sound insulation is good, purchase materials with dust-proof sound deadening strip when purchasing. With dust-proof sound deadening strip, sound insulation can be well and dust-proof at the same time;
5. If you do not want to do this, you must install a door stop (also called a door stop or limit) on the rail, and add elastic band Anti-collision on the frame.
Two tracks are enough. It depends on whether you like it or not. Generally, it will be better. As for the wall, you don't have to worry, the thinnest brick wall is enough.
At present, most of them are made of aluminum alloy and wood. You can choose better tracks and pulleys to achieve the mute effect. Specifically, you can go to the store to ask and talk. Sound insulation, it can only be said that the sound insulation effect is good, not completely sound insulation. The inside (outside) face can't hear the outside (inside) face. But the loud noise can still be heard. Because you need to move the door, there will be a gap, there will be no absolute sound insulation if there is a gap, and there will be a pulley, which is different from the door closing, but there will certainly be no noise. In fact, the kitchen does not need absolute sound insulation.
Besides, how big is your kitchen door? Do you need three doors? It is recommended to make two doors, usually 1.4~1.6m. In this way, when your door is opened, it is 1/2 of the width of the door, and it will feel much more beautiful. In fact, you don't need to consider any specific technology or something. As long as you go to the store to explain your requirements to him, he will explain it to you in detail and can do it. However, one thing needs to be noted. Before signing the contract, you need to look at the sample, such as tracks and pulleys, and indicate them in the contract.
