Cellulose weaving: an ecological and efficient solution
there Cellulose wadding Made from recycled paper is a natural insulator. It is highly appreciated for its sound insulation performance, but also for its ecological and economic aspects. In fact, it achieves excellent acoustic performance while having a low impact on the environment.
Benefits:
- Good acoustic performance
- Ecological and recyclable material
- Humidity regulation
Disadvantages:
- A longer and more complicated implementation
- Considerable thickness is required
In order to benefit from all the benefits of cellulose weeding, it must be taken care of density et al’thickness During implementation. Calling a professional to ensure proper installation of this insulation is also recommended.

Glass wool: a versatile acoustic insulator
Glass wool is one of the most widely used insulators in the field of sound insulation. It offers very good acoustic and thermal performance thanks to its honeycomb structure that absorbs and reduces sound. However, some of its disadvantages are particularly linked to air quality and its treatment at the end of its life.
Benefits:
- Versatile (phonic and thermal)
- Ease of installation
- Good value for money
Disadvantages:
- Possible release of inflammatory particles
- Difficult recycling
If you choose glass wool, do not hesitate to consult a professional to validate your choice, because not all products are equal in terms of performance and respect for the environment.

Rock wool: A fire-resistant option
there Rockwool Is an effective and resistant acoustic insulator, especially due to its mineral fiber composition. It provides very good acoustic performance and is also very effective in thermal insulation. On the other hand, it has some of the same disadvantages as glass wool, such as irritating particles and difficult recycling.
Benefits:
- Excellent performance with good fire resistance
- Insect resistant
- Good durability
Disadvantages:
- Possible release of inflammatory particles
- Difficult recycling
As with glass wool, it’s important to consult a professional to make sure you’re using the right product for your needs.

Polyurethane foam: efficient and flexible insulation
there Polyurethane foam (PU) is an insulator from the chemical industry that provides very good noise reduction performance. Its main advantage is its flexibility which allows numerous applications, as well as its excellent thermal resistance. However, it also has disadvantages, especially in terms of sustainability and environmental impact.
Benefits:
- Very good acoustic performance
- Flexibility (ideal for hard-to-reach spaces)
- Good thermal insulation
Disadvantages:
- Significant environmental impact (product and end of life)
- Limited durability
As always, it is recommended to consult a professional before choosing polyurethane foam as sound insulation.
