The sound-proof sliding partition walls Estfeller are a new way to divide spaces with elegance, while respecting the architectural environment in which they are inserted. They are composed of multiple individual elements, which flow along a horizontal guide attached to the ceiling, assembled one after another completing the entire wall. It is not necessary any guidance on the floor, handling the elements is simple, fast and safe. The advantage of a sounproof sliding wall is essentially to occupy reduced space when it is stored, and when the wall is composed of all its elements.
