Interior doors can be several types.

Interior doors can be several types. For example, you have a need to divide one large room into two, and at the same time I would like to maintain the space as much as possible, because ordinary doors take up a lot of space. In this case, you can easily use sliding systems that are securely attached to the ceiling and move silently in different directions. This will have two separate rooms, and its inhabitants will not interfere with each other.
