Sound insulation ceiling

How do I soundproof my ceiling?

In most situations, the sound of a ceiling is best insulated with a mass-spring-mass construction. This involves decoupling the existing ceiling structure (first mass) via a spring connection (for example, wooden or metal battens with elastic coupling) from a new, freely hanging layer of plasterboard (second mass). The space in between, the cavity, is filled with cavity fill.

A general rule of thumb is that the cavity should be filled to at least 70%, preferably evenly distributed across the entire surface. Note: the newly installed ceiling structure must not be in direct contact with the surrounding walls. For this, use edge strips, so that the ceiling is completely decoupled. This is also called a suspended ceiling.

Against which noises does a soundproof ceiling work?

An isolated ceiling is especially effective against airborne noise, such as voices. The combination of extra mass and decoupling ensures that these sounds are less likely to penetrate into the underlying space.

Is it about impact sounds, such as footsteps or sliding furniture? Then a suspended ceiling alone is often not enough. The ideal solution is a combination of a suspended ceiling and a floating floor in the room above.

Is it not possible to insulate the floor above, but you still want to reduce impact sound? Then a box-in-box construction is necessary. This means installing a completely decoupled structure within the room: with a floating floor, walls, and ceiling. This way, impact sounds are no longer transmitted through the building structure.

What material is suitable as cavity wall insulation?

For a suspended ceiling, we recommend cavity filling with good sound-insulating properties. Suitable materials are:

• Cyclin Pure – biobased and 100% circular, with a high mass.
• EASYpol – polyester wool, easy to process and dust-free.
• Ecosorb Metisse – made from recycled textile fibres, sustainable and effective.

These materials dampen sound waves and improve the acoustic performance of the entire structure.

What is the effect of the type of ceiling?

Not all ceilings are the same. A wooden ceiling requires a different approach than a concrete ceiling. Therefore, it is important to first determine which type of construction you are dealing with. View the page that fits your situation for a targeted solution.
