Therecellulose fiberis counted among theheat-insulating materials natural more ecological present ingreen building.
Therecellulose fiberit is marketed in the form of flakes, grains and panels; in all cases it isinsulating materialmade from recycled newspaper and then treated with boron salts to eliminate any risk of fire and make the material repellent for insects and rodents. All technical information on cellulose fiber can be found in our article dedicated toCellulose fiber in flakes. On this page we will examineadvantages and disadvantagesof the application of insulating material incellulose fiber.
Cellulose fiber, advantages
- Cold insulation
The thermal insulation offered by a material can translate into different yields when it comes tohot or cold. The coefficient of thermal conductivity of the fiber ofcelluloseis equal to λ: 0.032. In other words, the cellulose fiberoffers remarkable protection by protecting environments from the cold and preventing the formation of ice.
- Protection against humidity and mold
It can insulate walls, floors and ceilings protecting them from condensation, humidity and mold on the walls. Thisinsulatingit is completely breathable and works as a hygrometric balancer: thecellulose fiberit is capable of storing water and returning it when the climate becomes drier.
- Heat insulation
Therecellulose fibermanages to isolate the house from the heat when the installation can boast a density ranging from 55 to 60 km / m3. Therecellulose fiberoffers a damping value of around 70%, this means that the external heat will enter the house "damped" in this percentage.
- No risk of condensation
As it is an insulator, it reduces the temperature differences between day and night. For example, in the summer, during the day therecellulose fiberkeeps the house cool by absorbing heat, this material releases part of the heat during the night when the outside air cools.
Therecellulose fiberit has excellent characteristics as an acoustic insulator. Being a dense but flexible insulation, it is also effective for dry construction. The characterfibrousof thecelluloseensures good sound absorption: waves, which need air to propagate, oppose the hermetic barrier of the blown cellulose and are rapidly reduced.
- Fire protection
There cellulose fiber it is highly resistant to fire thanks to treatments with borax, a natural mineral.
- Environmental protection
Thisinsulating materialit is produced from recycled raw materials and manufactured with a minimum of energy investment.
- Natural repellent
The added additives (boron salts) are natural and can give thecellulose fiberparticular properties as a fungicide and natural repellent against insects and mice.
Cellulose fiber, disadvantages
Although there have been no documented cases in Italy, in France, thecellulose fiberit has often been the cause of major controversy. C2P (Commission Prevention Produits) and AQC (Agence qualité construction), French bodies responsible for the control of construction and non-construction products, have repeatedly cellulose fiberunder observation.
According to the French Commission, in fact, thecellulose fiberit would constitute a risk factor for those employed in housing. The case of thecellulose fiberin France it was partially resolved by coming to the conclusion that the safety of this insulator depends on the implementation which must be done in a workmanlike manner. For this reason, before proceeding with the use of panels, grains or cellulose fiber flakes for home insulation, we recommend that you contact a team of accredited experts.
