Sound insulation is an application designed to prevent external sounds from entering and to keep the sounds inside within the interior space. Its importance is significant in homes, offices, studios, and crowded areas such as hospitals or schools. By reducing noise, it provides a comfortable living environment while generally increasing efficiency. On a sectoral basis, it solves problems for areas that require insulated spaces and enhances sound quality. Sleep quality is definitely improved.

In addition to the insulation group divided into ceiling, floor, and wall sound insulation, window insulation—meaning specially laminated multi-layered glass—can also be added. Generally, barriered Bondex foams are among the leading sound insulation materials. For acoustic arrangements, non-flammable acoustic foams are used, and among vibration-absorbing materials, there are products such as Tecsound sound barriers. During the application, the correct choice of sound insulation materials is important. In some cases, the goal is to block sound transmission, while in other cases, the aim is acoustic regulation or vibration reduction. In this case, selecting the right material directly affects the benefit of the application.
