Acoustic insulation plays an essential role in improving sound comfort inside a home. It helps limit the propagation of noise from outside or neighboring rooms through the installation of specific insulating materials. This solution is particularly useful for mitigating disturbances related to traffic, neighbors, or impact noise in a building.
In Luxembourg, the cost of sound insulation work depends on several factors: the type of insulation chosen, the surface to be treated, the configuration of the home, and the desired level of acoustic performance.
In this guide, Avenir Rénovations presents the main elements that influence the price of acoustic insulation as well as the average budgets to prepare for your project.
The materials used for sound insulation are numerous and each has its technical characteristics and performance level. Therefore, the choice of material has a direct impact on the overall cost of the work.
A personalized study allows you to determine the most suitable insulation for your home, the necessary quantity, and the total budget to ensure effective noise reduction.
Here is an overview of the average prices practiced in Luxembourg for the main acoustic insulators.
| Acoustic Insulator | Material Price | Total Price with Installation |
| Mineral Wool | 8 to 30 €/m² | 35 to 75 €/m² |
| Vermiculite / Perlite | 35 to 55 €/m² | 60 to 95 €/m² |
| Cork | 40 to 65 €/m² | 65 to 110 €/m² |
| Cellulose Wadding | 18 to 30 €/m² | 45 to 75 €/m² |
| Wood Fibers | 22 to 40 €/m² | 50 to 85 €/m² |
| Acoustic Underlay | 5 to 15 €/m² | 25 to 45 €/m² |
Mineral wool, such as glass wool or rock wool, is one of the most commonly used sound insulators. It has the advantage of being relatively economical while offering good acoustic performance.
For a thickness of about 100 mm, its purchase price generally varies between 8 and 30 € per m². A complete insulation with installation included costs on average between 35 and 75 € per m² in Luxembourg.
Vermiculite and perlite are also used for their sound absorption properties. Derived from expanded minerals, they offer good sound performance.
Their purchase price generally ranges between 35 and 55 € per m², while complete insulation done by a professional can cost between 60 and 95 € per m².

Cork is a natural material particularly valued for its excellent acoustic and thermal performance. For a thickness of about 30 mm, its purchase price generally varies between 40 and 65 € per m². With installation included, the total cost is between 65 and 110 € per m² in Luxembourg.
Cellulose wadding, made from recycled paper, also represents an effective ecological solution. Its purchase price generally ranges between 18 and 30 € per m². Including installation, the total cost is estimated between 45 and 75 € per m².
Wood fiber panels are also used for their insulating properties. Their purchase price generally varies between 22 and 40 € per m², while complete insulation with installation costs between 50 and 85 € per m².
When installing parquet, adding an acoustic underlay is strongly recommended to reduce impact noises such as footsteps or falling objects.
This type of material, usually made of foam or a specific insulator, costs between 5 and 15 € per m² to purchase. With installation included, the total budget generally ranges between 25 and 45 € per m².
This solution effectively limits impact noise but is less effective at reducing airborne noise.
To achieve effective acoustic insulation, it is often necessary to install a double wall or decoupling system. Depending on whether the intervention concerns walls, floors, ceilings, or openings, the budget may vary.
In Luxembourg, certain financial aids can help reduce the cost of insulation work, especially when the intervention is part of an energy improvement project.
Public or municipal schemes may be granted when sound insulation is associated with thermal improvement of the home. National energy bonuses, subsidies for energy renovation, or certain local aids can thus reduce the amount of your investment.
It is generally necessary to hire a qualified company to benefit from these schemes.
Avenir Rénovations assists you in evaluating your budget and informs you about the financial aids you may be eligible for.
