Cellulose

Cellulose fiber is a natural, eco-friendly insulator derived from paper recycling

Cellulose occurs naturally as the main constituent of plants and trees.
Cellulose is the most common organic compound. No cellulose, no trees. No trees, no paper. Paperless, no natural thermal insulation.

Cellulose fiber is produced from recycled newspaper through a grinding and pressing process with flame-retardant mineral salt additives and fungicides. Once the process is completed, cellulose flakes are obtained which are perfect for use as thermal insulation of walls and attics.
Its use to insulate homes by blowing cellulose fiber dates back to the 1960s, and today new techniques make it one of the preferred materials, thanks also to its excellent quality/price ratio.

Breathability (μ)

1-2

Ability of a material to be passed through by water vapor
Protect yourself from condensation and mold: the lower its value, the greater your ability to dispose of internal moisture
Thermal Conductivity (λ)

0,037-0,042 W/mK

La capacità di una sostanza di trasmettere il calore
Per difendersi dal freddo: più basso è il suo valore, maggiore è la capacità di isolamento
Specific Heat Capacity (Cp)

2100 J/KgK

Amount of heat required to raise the temperature of a substance by one degree
To protect against heat: the higher its value, the slower it accumulates heat
Density (ρ)

30-50 Kg/m3

How is the mass of a material distributed in the space it occupies
To defend against heat: the greater its value, the greater its ability to defend against heat

Thermal comfort

Low thermal conductivity promotes a high thermal phase shift: external heat takes many hours to penetrate rooms, keeping them cool in summer and warm in winter

Acoustic insulation

The fibrous structure diffuses sound impacts and dampens airborne noises: cellulose-insulated walls, ceilings and covers offer perceptibly greater acoustic comfort

Moisture regulation and breathability

Cellulose is hygroscopic: it absorbs moisture and releases it into

gradual manner. This helps keep the internal microclimate more stable,

preventing mold or condensation

Fireproof

Thanks to natural treatments with natural mineral salts, the

fiber can achieve safety classes such as Bs2, d0 (or similar) according to the

EN 13501-1 standards; does not burn but chars

Durable

When well installed with the right laying density and protected from the elements, the fiber maintains its performance. It requires no maintenance.

In construction, cellulose is used in the following applications:

Pitched covers, uninhabited or habitable attics

Cellulose fiber is ideal for thermoacoustic insulation of pitched roofs and attics, both habitable and uninhabited. Applied for blowing or free-laying, it reduces winter heat loss and summer overheating, improving the internal comfort and energy efficiency of the building.

Wall cavities

Blowing cellulose fiber into wall cavities allows for continuous and effective insulation, without invasive interventions. Cellulose adapts perfectly to empty spaces, eliminating thermal bridges and improving the thermal and acoustic performance of perimeter walls.

Floors, false ceilings

Thanks to its light weight and ability to completely fill available volumes, cellulose fiber is perfect for insulating inter-storey floors and suspended ceilings. In addition to improving thermal insulation, it contributes significantly to the reduction of airborne noise between different environments.

Renovations where it is not possible to intervene from outside

In energy requalification projects where it is not possible to operate on the external facade, cellulose fiber represents a practical and minimally invasive solution. Blowing from the inside allows walls, attics or cavities to be insulated quickly, effectively and without complex masonry works.
