    Sound insulating pre-wall

    A sound insulating pre-wall is often the solution for reducing noise pollution from an adjacent room. This solution works against nuisance airborne noise (talking, television, etc) from neighbors on the other side of a wall.

    More about a front wall

    We have various user-friendly materials available that you can use as cavity fill to reduce neighbor noise. It's important when installing a sound-insulating cladding that it is decoupled from the existing partition wall. That's why we also refer to it as a floating or decoupled wall.

    We offer sound-insulating cladding to contracting companies (via quotation) and to individuals for DIY projects. In addition to the solutions shown, you'll find more information below.

    What is a soundproofing pre-wall?

    A sound-insulating cladding, or acoustic cladding, is installed in front of an existing wall to improve the sound insulation of your space. In addition to its acoustic properties, such a wall solution also serves a thermal function. Particularly in older houses or with thin partition walls (plasterboard walls), such a wall is used.

    For instance, exterior walls of houses built before 1930 usually do not have a cavity wall. As a result, there is often sound transmission between such houses, leading to nuisance. Even in houses built between 1930 and 1980 with a cavity wall, the insulation is not always optimal. Newer houses (from around 1980 onwards) are equipped with cavity walls, or even better. Nevertheless, cladding walls can still be valuable in certain situations.

    Cladding systems are also used to create soundproof studios (box-in-box). In a soundproof room, it is important to create a completely contact-free space that is detached from the structural floor, walls, and ceiling.

    Pre-wall sound insulation

    The sound insulation value of a cladding wall also depends on the sound insulation value of the existing wall. It can reach an Rw of 41-44dB. This is the weighted airborne sound insulation. It indicates the level in decibels to which sound is blocked. With sound insulation starting from 40dB, a normal conversation is hardly audible anymore. A conversation with raised voices is not easily intelligible.

    Acoustic insulation pre-wall

    If you want to build a wall yourself using studs, cavity fill, and plasterboard, it's important to mount the studs without any contact. This can be done, for example, using vibration isolation strips like EASYbond.

    Additionally, we also offer various materials that are excellent for cavity filling. These are placed between the studs. For cladding wall insulation, for example, we have EASYpol polyester wool and Ecosorb.

    These are sustainable and excellent alternatives to the well-known glass wool and rock wool panels.
