Although it is mostly applied for congress centers and meeting rooms in the first stage, the usage area has expanded over time and even in residential projects, movable partition panels are used in order to divide / combine space and to allow several functions in the same area. Wherever it is used, besides its opening-closing feature, sound insulation is the most important criterion in acoustic partition walls. When necessary, it is important to ensure comfort in terms of noise while continuing two different functions in two separate spaces divided by a partition wall. It should not be forgotten that environmental factors, acoustic insulation on floors, ceilings and walls along with the mechanical installation of the building are of great importance in terms of sound insulation, and necessary precautions should be taken to ensure full comfort.
