Sound insulation is essential to reduce or even eliminate unwanted noise in your home. It involves installing a material capable of limiting sounds and nuisances coming from outside on the concerned surfaces. The cost of the work is not fixed and can fluctuate based on various parameters.
Avenir Rénovations offers you a complete overview of the elements that influence the cost of sound insulation as well as the budget to consider for your project in Belgium.
Sound insulation materials are divided into several categories and display varied prices. A custom quote provided by Avenir Rénovations Belgium determines the most suitable product, its cost, and the quantity needed to achieve optimal reduction of unwanted noise.
| Soundproofing material | Price of material only | Total cost of insulation |
| Mineral wool | from 6 to 22 €/m² | from 22 to 52 €/m² |
| Vermiculite / Perlite | from 27 to 38 €/m² | from 42 to 68 €/m² |
| Cork | from 26 to 42 €/m² | from 43 to 72 €/m² |
| Cellulose wadding | from 13 to 19 €/m² | from 28 to 50 €/m² |
| Wood fibers | from 16 to 26 €/m² | from 32 to 57 €/m² |
| Soundproofing underlay | from 3 to 10 €/m² | from 16 to 25 €/m² |
The main advantage of mineral wool lies in its very economical price (on average between 5 and 20 €/m² for 100 mm), making it an ideal choice for small budgets. However, a significant thickness is necessary to effectively reduce sound transmission, which can increase the ecological footprint of the home. Sound insulation with this material costs between 20 and 50 €/m² (installation included).
Vermiculite comes from expanded mica, while perlite originates from a natural volcanic rock. The price of sound insulation with these products ranges from 25 to 35 €/m² (excluding labor). Including installation, you should budget between 40 and 65 €/m². For an accurate budget estimate, request a free quote from Avenir Rénovations Belgium.
Cork is an excellent option for those seeking effective sound insulation and having a comfortable budget. The cost of the material for 30 mm thickness ranges from 25 to 40 €/m². For complete cork insulation of 30 mm (installation included), the price ranges from 40 to 70 €/m².
Cellulose wadding costs between 12 and 18 €/m². For sound insulation made with this material, expect to pay between 27 and 48 €/m² for a thickness of 100 mm. As for wood fibers, their purchase price ranges from 15 to 25 €/m². Sound insulation of 100 mm based on this material costs between 30 and 55 €/m².
Installing parquet generally comes with a foam underlay designed to reduce impact noise (footsteps, falling objects, heels…). This type of foam offers good performance against shock noise but is less effective against airborne noise. Its purchase price ranges from 2 to 9 €/m². Including installation, the total cost of insulation with a soundproofing underlay for parquet varies between 15 and 24 €/m².
Effective sound insulation relies on decoupling the walls of the room to be treated. This separation occurs at the ceiling, walls, doors, windows, and floor of the concerned room. Depending on the part of the home to be insulated, the overall cost of the work can vary. This renovation guide informs you about the price of sound insulation according to each area to be treated in your home.
In Belgium, several programs support individuals wishing to improve the sound comfort of their homes. The Housing Fund and the regions (Wallonia, Brussels-Capital, Flanders) offer renovation grants to reduce the overall cost of the work. Households living near an airport can also benefit from the Sound Insulation Plan (PIA), funded by public authorities. Compensation is awarded based on the number of affected rooms and the level of disturbance, defined by three distinct noise zones.
Carrying out this type of work also grants access to certain aids related to energy efficiency. You can benefit, for example, from a reduced VAT of 6%, the regional Energy grant, or tax deductions, provided that the work is carried out by an approved contractor.
