CONSTRUCTION SOLUTION
Data based on a wall under 3 meters high with channels and studs.
1) SE-BEC-6×80 (SENOR) SELF-ADHESIVE ACOUSTIC STRIP: Made of high-quality EPDM material (perimeter seal), providing both airtightness to the solution and elasticity around the perimeter.
2) Absorptive material: ROCK WOOL (glass or rock wool) or POLYESTER FIBRE, placed in the air cavity. We recommend using two layers of this material to improve the absorption coefficient (one layer within the structure and another between the structure and the wall). A thickness of 50 mm and a density of around 30 kg/m³ is recommended.
3) Compatible dampers:
* SE-3800/TD1+TA Damper:Installed on vertical studs with MM (Metal-Metal) screws. It includes 4.2×70 screws and M6 wide-wing washers for wall installation. The operator controls the axial compression of the damper’s polymer (rubber) by adjusting the force applied when tightening the screw, ensuring it is not over-compressed. It is used for cavity walls with an air gap of more than 10 cm and a maximum height of 4.5 m. It features a steel bracket with a thickness of 1.5 mm. If there is any excess bracket material beyond the outer line of the studs, it can be cut with an angle grinder.

The recommended placement on the studs is 2 (two) dampers on odd-numbered profiles and 1 (one) damper on even-numbered profiles.
For optimal acoustic performance in self-supporting partition walls, it’s essential to use dampers on the perimeter profiles as well. This adds elasticity to the entire metal structure and prevents rigid connections or acoustic bridges, meaning the screws don’t make contact with the profiles, which helps to stop vibrations from transferring between the original building structure and the partition.
Below, we list the most in-demand products of this type:
✓ SE-TAV-500/11 A(blue rubber): This damper is designed for installation on horizontal floor profiles and vertical profiles adjacent to the wall. It comes with 3.5×55 mm screws and 6 mm nylon plugs. Installation requires drilling a 12.5 mm hole in the profiles.
For optimal results, a stepped metal drill bit is recommended for ease of use.
- Box formats: 12 units.
✓ SE-TAV-500/11 R(red rubber): This damper is designed for installation on horizontal ceiling profiles. It includes 3.5×55 mm screws and 6 mm nylon plugs. Installation requires drilling a 12.5 mm hole in the profiles.
A stepped metal drill bit is recommended for ease of use.
- Box formats: 12 units.
✓ SE-TMT/50 R: This damper is used in cases where there is an uneven floor level. It is installed beneath the horizontal floor profiles and features a dual-fixation base with an EPDM pad for improved stability. Additionally, it includes a unique levelling system that compensates for floor irregularities of up to 2 cm, ensuring an even weight distribution across all dampers and optimising performance.
This levelling system simplifies installation and saves time, as it allows the use of studs of uniform length.
- Box formats: 25 units.
4) Profiles: Installed vertically every 60 cm, they provide rigidity to the solution.
NOTE: For this guide, we have considered using 48 mm channels and studs. However, other sizes are available on the market, including 36 mm (not recommended for soundproofing), 55 mm, 70 mm, 90 mm, 100 mm, 125 mm, 150 mm, and more.
5) SE-MONT-BICAPA-40 Decoupling Strip (SENOR): This strip acts as a separator between the profiles and plasterboards, helping to dampen vibrations.
6) Plasterboard: For the first layer of boards, we recommend using 15 mm plasterboard (approx. 10.5 kg/m²) to add mass to the system.
7) Acoustic Membrane (Bituminous): We recommend using ViscoLAM 65 (ChovA), M.A.D. 4 (DANOSA), TECSOUND (SOPREMA), or a similar 4 mm thick membrane (approximately 6 kg/m²). It acts as a barrier against airborne noise transmission and, due to its high density, adds mass to the system. Acoustic membranes with a 4 mm thickness provide better acoustic performance than 2 mm alternatives.
8) Plasterboard: For the second layer of boards, we recommend using 12.5 mm plasterboard (approximately 8.5 kg/m²) to further enhance the mass of the system.
NOTE: Standard plasterboards (approx. 700 kg/m³ density) or acoustic plasterboards (approx. 1,000 kg/m³ density) can be used. The density of the boards varies by manufacturer. Acoustic plasterboards, having a higher density than standard ones, contribute more mass to the system, thereby improving soundproofing.
SPACE/THICKNESS OF THE SOLUTION:
We operate on the principle that greater thickness leads to enhanced soundproofing.
As such, a self-supporting wall lining with channels and studs will deliver outstanding acoustic results. This solution is ideal when space is not a limiting factor.

TIPS:
Seal all holes or gaps in the original wall/ceiling before applying the treatment to ensure airtightness.
When working with a newly constructed wall or ceiling, it is recommended not to place the dampers directly onto the bricks. The wall should have a mortar layer of approximately 1 cm.
Seal the joints between the plasterboard and the perimeter, as well as between the boards themselves, in both the first and second layers.
The profiles and plasterboard must be fully “supported” along their entire length by the acoustic strip. Therefore, the strip’s width should be equal to or greater than the thickness of the solution.
To achieve optimal acoustic results, it is advisable to avoid drilling into the system.
It is recommended to carry out a holistic treatment on the walls, ceiling, and floor (box within a box) to achieve the best acoustic results.
For securing the dampers, we recommend 8mm nylon plugs and screws ranging from 65mm to 75mm in length.
For securing the first layer of boards, we recommend using 25mm or 35mm long phosphated screws, and for the second layer, 45mm long screws.
NOTE 1: The solution outlined has been developed based on our expertise and experience. Please note that this is not the only approach, as several combinations with different components are possible. We strive to offer support and guidance in resolving the noise issues that, regrettably, affect many individuals.
NOTE 2: Using high-quality products and ensuring proper installation are essential for achieving optimal acoustic results. Therefore, it is crucial to be thoroughly aware in order to avoid mistakes that could undermine the said enhancement.
NOTE 3: Soundproofing encompasses rigidity, elasticity, mass, sealing, absorption coefficient, and proper execution. Various type of materials are used to achieve these factors, and when combined correctly, they enable us to obtain the desired acoustic results. Kindly note that there are no miracle products capable of solving noise issues on their own. Omitting some of the required factors, and consequently replacing components, will lead to a substandard system and a reduction in soundproofing. In other words, a wasted financial and time investment in the project.
