When do you insulate a concrete ceiling?
Due to the relatively high mass of a concrete ceiling, airborne sounds are generally sufficiently muffled. In situations where there is significant airborne noise, such as in a restaurant or music studio, additional soundproofing may be necessary. In such cases, it is important to investigate whether a floating ceiling, an extra ceiling that you install to improve sound insulation, provides adequate effect. In some cases, a full box-in-box construction is required. This involves combining a floating ceiling with decoupled walls and a floating floor.
Contact noise can best be addressed at the source. Vibrations transfer through the floor to the walls and are therefore still audible in the space below. Hence, a soundproof ceiling can provide a solution, but installing a floating floor on top often has the preference. Also, in the case of impact noise, it is important to assess whether a combination with decoupled partition walls and a floating floor is necessary.
How to insulate a concrete ceiling?
Sound from the ceiling is insulated by installing a suspended ceiling. This is done through the following steps:
- Secure the mounting system with acoustic decoupling to the existing ceiling.
- Apply a cavity fill in the gap, such as Ecosorb Metisse.
- Mount two layers of plasterboard against the system. Ensure that the boards are free from the walls; use a edge strip around.
- Finish the whole neatly with a finishing of your choice, for example by skimming it.
