How to handle the height difference between carpet and marble in hotel rooms and corridors?

The corridor is marble, while the rooms are carpeted. If the door gap is too small, the door will get stuck on the carpet; if it's too large, the sound insulation is completely ruined.

We provide "Drop Seal" soundproofing strips for hotel projects. These automatically adapt to a height difference of 5-15mm, ensuring smooth sliding on the carpet and automatically sealing when the door is closed.
