Cellulose Fiber Acoustic Spray - Acsilo

Cellulose Fiber Acoustic Spray - Acsilo

Cellulose Fiber Acoustic Spray is an environmentally friendly and substainable material made from recycled fibers and boron salts using advanced technology. It has excellent acoustic and thermal insulation properties.

The cellulose wool is sprayed in fiber form onto the desired surface.

The first applications of cellulose-based insulation began in the 1970s in the United States and spread throughout the world due to its ecological and sustainable nature.

Technical Specifications

TS EN 13501-1 (Reaction to Fire) : B
TS EN 12667 (Thermal Conductivity X) : 0.037 W/(m-K)

Thermal Volume is the amount of energy required to heat or cool one kilogram of material by one degree Celsius. The material will be more insulating if the value is high. Glasswool has a thermal capacity of 670 joules per kg, while rockwool has a capacity of 860 joules per kg. According to EN ISO 10456, the thermal capacity of cellulose-base insulation produts is close to 1600 joules per kg (A performance 2-2.5 times better that their substitutes).

Natural, Durable, and Risk-free Sound Absorption

This spray plaster is primarily made up of recycled natural cellulose fibres. By combining it with additives, Acsilo spray improves serviceability and fire safety. Acsilo Spray is a sprayed water-base polymer. We used borates to a bare minimum, well below the EU limit of 5%. As a result, our contractors and customers can trust Acsilo spray.


Acoustic spraying can be used almost anywhere, including new and old buildings, along with horizontal and vertical surfaces made of identified roof panels, concrete, and plasterboard. Acsilo acoustic solutions offer limited design freedom while still providing good speech intelligibility, high concentration levels, privacy, and thus a high level of comfort.

Benefits of Acsilo Acoustic solutions

Acsilo improves room acoustics with its acoustic and directional sound absorbing properties. Acsilo provides maximum absorption with minimal height loss. Since it is spray based it is long-lasting, reduces reverberation and saves energy. Acsilo's acoustic products comes in a wide range of colours and are suitable for a variety of substrates. The Advantages of Acsilo are:

  • Lowers reverberation in any room.
  • Maximum absorption with least amount of height loss.
  • Appropriate for all surfaces, including ceilings and walls.
  • Provides design freedom and durable.
  • Results in energy savings of 5% to 10%.
  • Available in any color and surface finish ranging from coarse-grained to smooth surface.
  • Furthermore, acoustic spraying and plastering are very easy to maintain and come with a standard 2 years warranty on adhesion and acoustic effect.


  • Made from recycled paper.
  • No-flammable and fire-resistant material.
  • There will be no sound or heat bridges because the insulated surface or volume is sprayed or laid.
  • Excellent acoustic performance and loss of airborne sound between the spaces.
  • It is long-lasting and requires no maintenance.
  • Excellent loss of airborne sound between the spaces.
  • Absorbs VOCs (Voltage Organic Components) and toxins in the air.
  • It does not collapse or wear out as a result of dusting.
  • The thermal capacity of cellulose is 2-2,5 times better than their substitutes with excellent thermal perfromance in both winter and summer.
  • No convection occurs.
  • It breathes and has vapour permeability.
  • Resistance to erosion.
  • Has the ability to absorb and release moisture without affecting thermal performance.
  • Electrical resistance and energy conservation.


  • It poses no risk to human health.
  • Does not itch or irritate.
  • Absorbs VOCs and toxins from the air.
  • It is free of toxins and allergens.
  • Rot-resistant, inhibiting fungi, microorganisms, and pests.

The material is sprayed and ahered to the surface using the installation machine. This methos is used on inner and outer walls, prefabricated buildings, and corrugated roofing sheets, among other things.


The material is simple to clean with a vacuum and a soft brush. If the plaster is damaged, it is simple to repair locally. Tranquil offers a 2-Year warranty on Acsilo Spray adhesion and acoustic performance.
