Cellulose insulation boards are increasingly popular in the field of thermal and acoustic insulation of buildings. Made from recycled paper, these eco-friendly materials offer excellent thermal performance and are an attractive alternative to traditional insulation.
What is cellulose wadding?
Cellulose wadding is an insulating material made from recycled paper fibers, usually from newspapers. This process makes it possible to recover paper waste while reducing the environmental impact linked to the production of new materials. The cellulose wadding is treated with flame retardant and fungicide additives to give it fire resistance and limit the risk of mold and harmful insects.
The benefits of cellulose insulation boards
Thermal performance
The main advantage of cellulose insulation boards lies in their high thermal performance. Indeed, cellulose wadding has a low thermal conductivity, which allows it to maintain a stable temperature inside the building. In addition, its ability to trap still air gives it very good performance in terms of sound insulation.
Ecology and sustainable development
Cellulose insulation boards are made from recycled paper, making it an environmentally friendly and environmentally friendly material. In addition, the manufacturing process for cellulose wadding panels consumes little energy and produces very little waste, compared to other types of insulation.
Humidity regulation
Cellulose wadding is able to absorb and restore the humidity present in the ambient air, thus helping to regulate the humidity level inside the building. This limits problems related to condensation and mold, while improving living comfort.
Installation of cellulose insulation panels
Cellulose insulation panels can be laid using different techniques, depending on the configuration of the site and the technical requirements of the project:
- crawling pose : the panels are fixed directly to the rfollowings of the roof, horizontally or inclined
- wall installation : the panels are inserted between the uprights of a partition, generally made of wood or metal
- laying in dubbing : the panels are fixed on a rigid support, then covered with a facing (plasterboard, paneling, etc.)
- underlayment : the panels are placed directly under the roof covering, without mechanical fastening
The installation of cellulose insulation panels generally requires the intervention of a qualified professional, who can advise on the most suitable technique and ensure that it is implemented in accordance with the rules of the trade.
Comparison with other types of insulation
Mineral wool insulation boards
Mineral wool insulation boards (glass wool or rock wool) are widely used in the construction sector. If their thermal performance is comparable to that of cellulose wadding, they have some disadvantages:
- less environmentally friendly, as they are made from non-renewable resources
- can irritate the skin and respiratory tract during application
- less effective in terms of sound insulation
Polystyrene or polyurethane insulation panels
Polystyrene or polyurethane insulation panels have good thermal performance, but also have certain disadvantages:
- non-ecological, because they are made from fossil resources
- can release toxic gases in case of fire
- do not contribute to the regulation of ambient humidity
In comparison, cellulose insulation panels offer many advantages: ecology, thermal and acoustic performance, humidity regulation. They are therefore an interesting solution for those who wish to favor a durable and environmentally friendly material.
