Traditional materials for an effective soundproofing partition
When talking about soundproofing partitions, several classic materials are regularly used. Each has its own specific characteristics that must be considered when selecting.
Concrete Blocks
Concrete is often considered one of the best materials for building noise barriers due to its high mass, which helps absorb sound. Its acoustic efficiency is often measured by its sound reduction index (Rw), which can reach up to 60 dB, making concrete ideal for noisy environments. However, there are some drawbacks, including its relatively high cost and weight. The need for suitable support structures must also be considered.
Plasterboard
Plasterboard, such as Placo , are lightweight and less expensive than concrete. They provide satisfactory thermal insulation and can be reinforced with specific insulation materials, such as rock wool or glass wool. The use of sound-absorbing plasterboard significantly improves sound insulation. Furthermore, these boards are easy to install, making them a popular choice for renovation projects.Wood Panels
Wood panels, such as those from Saint-Gobain, are also a common option for sound-absorbing partitions. Although their sound insulation performance is generally lower than that of plasterboard or concrete, they offer an attractive aesthetic. Their versatility also allows for the creation of different designs while still providing reasonable insulation. It is important to choose high-density wood panels for best performance. Material
Rw (dB) Weight (kg/m²)Cost (€/m²)
| Concrete | ≥ 60 | ≥ 300 | 70 |
|---|---|---|---|
| Plasterboard | ≥ 50 | 10 – 15 | 25 |
| Wood Panels | 40 – 50 | 20 – 30 | 30 |
| Specific Materials for Sound Insulation | To complement traditional materials, several specific solutions guarantee better sound insulation. These materials are specially designed to combat noise pollution. | Glass Wool | Made of mineral fibers, glass wool is a highly effective insulator, both acoustically and thermally. Installed between partition walls or applied to existing walls, it can reduce noise by up to 25 dB. Another advantage is that it meets fire resistance standards, making it suitable for commercial and residential use. |
Rock Wool
Similar to glass wool, rock wool offers superior fire resistance and is less sensitive to moisture. Thanks to its density, it effectively absorbs sound, improving the soundproofing of living spaces. Furthermore, rock wool is made from natural raw materials, which contributes to its popularity among environmentally conscious users.
Expanded Cork
Expanded cork is a natural material considered environmentally friendly. It has excellent acoustic and thermal insulation properties. Its ability to reduce impact noise is particularly appreciated. Due to its cellular structure, cork helps dampen resonances while providing long-lasting insulation. It is an ideal choice for those looking for a responsible alternative to synthetic materials.
Innovations in Sound Insulation
The soundproofing industry has evolved with the integration of new technologies and methods. These innovations provide even more effective solutions for reducing noise. Double-Wall Partitions
Double-wall partitions consist of two independent structures that create an air space between them. This configuration provides significantly better sound insulation than single-wall partitions. By using hollow-core plasterboard, sound reduction performance can reach very high levels, making these partitions ideal for noisy or noise-sensitive environments.
Acoustic Seals
Acoustic seals are essential in any construction to improve airtightness and thus reduce sound leakage. These foam or rubber seals are particularly effective around windows and doors, areas often vulnerable to noise transmission. Their judicious use can lead to a 5 to 10 dB reduction in incoming noise.
Anti-vibration mounting systems
These systems limit the transmission of vibrations between the different parts of a partition wall. They are invaluable when hanging acoustic panels or plasterboard. A well-integrated structure and suitable mountings therefore contribute to better overall insulation.
Soundproofing existing partition walls
It may be necessary to improve the soundproofing of existing partition walls. Several techniques are effective in this area.
Improving airtightness
Good airtightness is crucial to limit noise transmission. Inspection and blower door tests can identify leaks caused by cracks or poorly fitted joints. To address these issues, the use of acrylic sealant, sealing strips, and expanding foam is very effective in eliminating infiltration. Studies show that proper sealing can increase sound attenuation by up to 15 dB.
Acoustic bridges, often consisting of rigid elements passing through the partition (ducts, electrical outlets, etc.), can transmit noise directly. Solutions such as anti-vibration sleeves and acoustic flush-mounting boxes can reduce sound transmission through these elements. Significant gains, around 10 dB, can be achieved with these installations.
Adding insulation layers
Adding insulating layers to the existing partition can also significantly improve soundproofing. Soundproof plasterboard, specifically designed for this purpose, can form an effective barrier. A double layer of insulation combined with sound-absorbing membranes can significantly improve results, with potential noise reductions of 10 to 15 dB.

Constructing new partitions: integrating soundproofing
When constructing new partitions, focusing on integrating soundproofing is key. This promotes long-term efficiency for users. Choosing Materials for an Effective Partition
Material selection should be based on their sound reduction index (Rw), as well as their mass and density. Heavy materials, such as those from Rockwool or Isover, are known for their superior acoustic efficiency. A multi-layer approach, combining various materials, often optimizes insulation. Construction Techniques to Maximize Insulation When installing partition walls, various techniques can be adopted to improve sound performance. Double-wall construction is recommended, as these systems with reinforced air spaces are particularly effective. Similarly, the creation of solid concrete partitions ensures significant sound inertia. To meet contemporary needs, the use of insulated metal frames is an excellent alternative, offering flexibility and lightness.
Assemblies and Construction Details
Construction details facilitate airtightness. Joints must be systematically treated to eliminate sound leaks. Anti-vibration fasteners must be used to ensure optimal acoustic performance. Attention paid to pipe penetrations and other construction elements further enhances the insulation effect. https://www.tiktok.com/@/video/7458080165428563205?u_code=0&sharer_language=en
