Box-in-box construction
A box-in-box construction is a solution for acoustically isolating spaces with high noise requirements. This construction method involves building a fully decoupled floor, wall, and ceiling structure within the existing space. Thanks to acoustic decoupling and the mass-spring-mass principle, vibrations and sound transmission to the surrounding structure are minimized. This prevents sound from leaving the room or entering from outside, thereby acoustically sealing the space from the environment.
When do you apply a box-in-box construction?
This construction method is used when standard soundproofing solutions are insufficient to control noise transmission. This applies, for example, to heavy installations or situations where disruptive noise from outside or to the outside is present. Think of music studios, cinemas, concert halls, machine rooms, or utility buildings in noisy environments.
How does a box-in-box construction work technically?
The principle of a box-in-box construction is based on acoustic decoupling and mass-spring-mass construction. Floor, walls, and ceiling are installed separately from the existing structure and connected via vibration-damping fixing points. Between the construction layers, a cavity is created that can be filled with sound-absorbing material. This layered construction prevents structural vibrations and airborne noise from propagating through the existing structure.
What products are needed for a box-in-box construction?
For the construction of a box-in-box construction, acoustic mounting systems are required, such as vibration-isolating EASYmount floor supports, ceiling hangers, and wall brackets. Additionally, cavity fillings are essential to damp reflections in the air gap. The finishing is usually with heavy cladding, such as gypsum fiber boards, to achieve the necessary mass. The choice and coordination of these components determine the final insulation value of the construction.
