Those who look for an ecological insulation material sooner or later come out of cellulose insulation. This material consists of recycled newspaper that has been reworked into flakes. To obtain a higher fire resistance, some non-harmful chemicals are added. In the same way, the newspaper paper is prevented from rotting. Of course, only chemicals are used that do not have a negative impact on the environment, because the ecological character of the cellulose would otherwise disappear. Especially within passive houses, cellulose is often chosen as an isolator.
What is cellulose?
Cellulose is a material made from recycled newspaper. To this, various chemical substances and a number of minerals are added to make the agent fire-resistant. Cellulose is ideal for sound insulation and heat insulation. Cellulose is often used between floors with wooden floors and ceilings to limit the noise.
Benefits of cellulosic material
Cellulose offers good insulation. The thermal conductivity coefficient of cellulose based on newsprint is between 0.035 and 0.040 W/mK. The higher this value, the better! For comparison: cork is around 0.039W/mK, sheep’s wool around 0.038 W/mK and straw and canes around 0.056 W/mK, but of course they are a lot less flammable. The cellulose insulation blower works perfectly in this matter.
Cellulose also prevents condensation, which in any case does not affect the construction in that area. Recycling is also very environmentally friendly, it is safe in fire thanks to the added minerals, breathes the stuff and the insulation in the summer is also very good. Moreover, it keeps out sound very well.
Can I apply cellulose insulation myself?
In theory, it is possible to apply the insulation yourself. The bags with cellulose material are easy to order. However, ensuring that the material is spread well is a lot more difficult. If you have more often chopped this ax you could possibly do it yourself, but otherwise it might be advisable to leave it to specialists. Cellulose is usually loose material, but can also be supplied in plates. If it concerns small surfaces then you could possibly choose the plates, but these are very difficult to install between a ceiling and a floor; injecting is then a practically more workable solution. With the fiberglass insulation blower the options come pretty fine.
Apply cellulose in the home
Cellulose is not placed, but injected under pressure. This is done by means of a kind of blower. The space in which the cellulose ends up has to be closed, so that the flakes can no longer leave. The overpressure ensures that the flakes fit nicely together and holes or cracks are avoided. This is very important, because every gap could lead to a thermal bridge and a loss of heat and energy.
Sustainable insulation is good for the wallet in the long term. For example, cellulose can be used to insulate in a sustainable way. Cellulose is a durable insulation material and consists of paper flakes. Cellulose is mainly used in roof insulation, floor insulation and wall insulation. Now that the insulation blower machine parts are available all over, you will not face any problem in keeping a machine for the insulation process for a long time.
Why isolate with cellulose?
About us:- Cellulose is one of the oldest insulation materials that exist. Today, cellulose is made by grinding old newspapers into flakes that are then treated with a boric acid solution to make them fire-resistant. This manufacturing process was already used in the 1950s and became more popular in the 1970s.
