People often asks, ‘’what is communicating door?’’ and ‘’why we use it?’’
There’s not quiet a big difference between a communicating door and a normal entry door except an extra door slab. Usually it’s used in hotel family room or conference room. The main purpose for two door slabs is to show respect to person living in the next room. When the people wants to enter the room next to door, besides opening his own door, she/he will also have to ask the permission from the people living in there. Beyond this, communicating door possesses a much better soundproof than normal entry doors which is also a respect for people living in both rooms.
