    Soundproofing on a concrete ceiling

    Do you have a concrete ceiling, but still experience noise from the room above? In some cases, it may be useful to improve the sound insulation of the ceiling. Concrete naturally has a high mass, but that doesn’t mean all sounds are blocked. Especially impact noises, such as footsteps, can still be audible. For an effective solution, it is often necessary to combine ceiling insulation with a well-insulated floor in the space above.

    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:

    1. Secure the mounting system with acoustic decoupling to the existing ceiling.
    2. Apply a cavity fill in the gap, such as Ecosorb Metisse.
    3. Mount two layers of plasterboard against the system. Ensure that the boards are free from the walls; use a edge strip around.
    4. Finish the whole neatly with a finishing of your choice, for example by skimming it.
