Blown cellulose wadding
is distinguished by its composition based on recycled cellulose fibers, thus offering an ecological profile for both the thermal and acoustic insulation of buildings. This bio-sourced material has interesting properties, in particular its permeability to water vapor. Resistance to humidity The resistance to humidity of cellulose wadding is often seen as one of its major advantages. This material doesn’t just shrug off moisture. Thanks to his character
hygroscopic
And capillary , it has the capacity to absorb humidity up to 15% of its weight. When it is able to evacuate this humidity by diffusion, it prevents condensation inside the structures. The hygrometric balancer function allows cellulose wadding to act as a real climate regulator for the home, promoting a healthy environment. This property makes it a predominant choice for older buildings and those likely to be subject to varying humidity levels.The limits of blown cellulose insulation
Despite its qualities, blown cellulose wadding is not without its limits. The thickness of insulation applied plays a major role. Insufficient insulation can cause condensation and, consequently, humidity problems. Therefore, the right dosage is essential to avoid any degradation of the structures.
Rodents can also be a problem, as these pests are attracted to organic materials. Specific treatments exist to prevent their presence, ensuring the durability of the insulating properties of cellulose wadding.
Comparison with other insulating materials
Cellulose wadding stands out from synthetic insulation. Although these can offer thermal performance, they do not have the same ability to manage humidity. In comparison, insulation such as polystyrene or glass wool tends to retain humidity, sometimes leading to inconveniences such as moldy spaces or damage.
Conclusion on the effectiveness of blown cellulose wadding
In the field of eco-construction, blown cellulose wadding is a wise choice for insulation, even when faced with humidity. Its ability to regulate humidity, coupled with its ecological aspects, makes it a solution that is both efficient and environmentally friendly.
Thus, its adoption guarantees a healthy interior while preserving structures from the harmful effects of humidity, a key issue for any sustainable construction.

Frequently asked questions about blown cellulose insulation and humidity
Yes, blown cellulose wadding is designed to be resistant to humidity. It has properties that allow it to absorb humidity while regulating ambient humidity, which makes it an excellent choice for insulating buildings.
Is cellulose wadding effective against condensation?
Yes, cellulose wadding is effective in reducing condensation. Thanks to its high water vapour permeability, it allows moisture generated from the inside to escape, minimising the risk of condensation in walls or attics.
What is the risk of moisture for blown cellulose insulation?
Although cellulose wadding is resistant to moisture, a lack of sealing or insufficient insulation thickness can lead to condensation problems. It is therefore essential to ensure correct installation to optimise its effectiveness.
Can blown cellulose absorb water?
Yes, blown cellulose is a hygroscopic material, meaning it can absorb up to 15% of its weight in water. However, it is also capable of releasing this humidity when conditions permit, thus acting as a humidity regulator.
Does humidity damage blown cellulose wadding?
No, blown cellulose wadding is not easily damaged by moisture, as long as it is properly installed and ventilated. It is designed to resist the damaging effects of humidity, but it is important to ensure that the space remains dry and well ventilated.
What are the consequences of poor insulation with cellulose wadding in the face of humidity?
Poorly performed insulation can lead to an accumulation of humidity, which can cause mold, damage to structures and poorer performance of the insulation. Insufficient thickness can also encourage condensation.
Does cellulose wadding require special maintenance due to humidity?
Cellulose wadding does not require any special maintenance, but it is recommended to monitor the condition of the insulation regularly. If excessive humidity or mold is detected, it is necessary to intervene quickly to avoid damage.
