cellulose insulation
RESPONSES TO COMMON MISCONCEPTIONS
cellulose insulation used for over a century
in countries accustomed to extreme temperature variations (Canada, Finland, etc.). However, in France, some misconceptions persist.
At Igloo France Cellulose, we value transparency and have decided to separate fact from fiction!
1.
cellulose insulation flammable.
The densely intertwined fibers that make up cellulose insulation slow down the passage of heat and therefore the spread of fire within the insulation. When exposed to flames, cellulose insulation on the surface, limiting the spread of fire to adjacent elements (framework, etc.).
On the left, 35 cm of cellulose insulation. On the right, 35 cm of glass wool. (Time expressed in seconds).
Cellulose cellulose insulation is heavy.
ECIMA (Association of cellulose insulation Manufacturers cellulose insulation France) conducted tests on the mechanical behavior of a ceiling under a distributed load in accordance with the rules of DTU 25.41 of 2012 and the guide for the presentation of elements of the technical opinion request file relating to a suspended ceiling process consisting of panels on a metal or wooden frame (CSTB, October 2012).
Each ceiling tested consists of BA13 NF plasterboard panels screwed onto furring strips spaced 0.60 m apart and fixed to the joists by hangers spaced 1.20 m apart. These tests on the mechanical behavior of a ceiling under a distributed load showed a maximum deformation of less than 5 mm with an insulation mass of 16 kg/m², in accordance with DTU 25.41: the blowing of cellulose insulation a ceiling up to a thermal resistance of 12 m²·K/W is therefore validated.

3.
cellulose insulation dusty.
When blowing insulation into attic spaces, wearing a P2 dust mask is mandatory. The cellulose insulation by Igloo France Cellulose is dust-free during the manufacturing cycle to facilitate its application.
cellulose insulation is not compatible with glass wool.
The NF DTU 45.11 standard, which regulates the blowing of loose-fill insulation into unused attic spaces, does not require the removal of old insulation beforehand. However, professionals still recommend doing so in order to assess the performance of cellulose insulation and limit the risks associated with the aging of mineral wool.

5.
cellulose insulation dangerous.
cellulose insulation made from recycled paper fiber and salts to improve its fire resistance. This composition is now covered by an FDES (French Environmental Declaration and Summary) and is not harmful to living beings. The emissions of volatile substances into the indoor air from our cellulose wadding are certified A or A+.
Cellulose cellulose insulation is not as effective as mineral wool.
The phase shift (the time it takes for heat to pass through insulation) of cellulose insulation more than twice that of mineral wool. It therefore offers better thermal performance than mineral wool.
Time taken for heat to pass through blown insulation with an R-value of 7:

cellulose insulation rodents.
Because it is made from recycled paper, cellulose insulation unfavorable to rodents. cellulose insulation flakes cellulose insulation to stick to the moist noses of these small mammals, preventing them from breathing and finding their way around.
cellulose insulation settles.
The phenomenon of cellulose insulation settling cellulose insulation well known and measured. It is therefore taken into account when applying it by blowing into attic spaces, thanks to the data provided in the ACERMI certification, which indicates the thickness to be blown in order to obtain the desired final thickness after settling.

9.
cellulose insulation to moisture.
cellulose insulation hygroscopic properties, meaning it acts like a sponge: it absorbs excess moisture from the atmosphere and releases it when the air becomes drier, without compromising its performance. This ability provides real additional thermal comfort in both winter and summer.
cellulose insulation more than mineral wool.
While this observation was true several years ago, today the cost of blowing cellulose insulation into attic spaces cellulose insulation equivalent to the cost of blowing mineral wool. The thermal performance of cellulose insulation also cellulose insulation heat to be retained inside the home for longer in winter, thereby reducing the need for heating. In summer, it takes longer for heat to penetrate the home, maintaining a constant temperature inside. This results in energy savings on a daily basis.
