Sprayed acoustic coating (Sonaspray)

Composition

Mixture of recycled cellulose, glue and water.

Scope of application

Sonaspray is a seamless acoustic roof that is projected onto ceilings and walls.

Sonaspray is a product that reduces reverberation time and noise due to its excellent sound absorption performance. Thus, it contributes significantly to the improvement of acoustics and the related mental and physical well-being. It can be applied on almost all substrates and can thus follow all the shapes of each construction.

It is applied by spraying (mixture of 80% water and 20% adhesive).

Sonacoustic is an ideal solution for public places, libraries, places of worship, concert halls, rest rooms, fitness centres or theatres.

We can apply it to the following substrates:

The materials used in construction, whether concrete, plaster or glass etc...

Exceptional sound absorption
Applicable to many surface configurations
Clean, ecological and sustainable nature
Low weight, no additional load on the structure
Very wide choice of finishes
Reduces the noise coefficient
Ideal for the finest and most artistic creations

Legal bases

In the field of environmental acoustics, the legal basis is mainly the LPE and OPB. These are federal provisions, which of course apply throughout Switzerland. However, in each canton, provisions (decree, ordinance or law) specify how federal legislation is to be applied. It is therefore prudent, if not necessary, to contact the specialised service of the canton in question in order to find out any specificities.

With regard to the acoustics of the building, Art. 32 OPB refers to SIA 181, which contains the applicable provisions.

Fire System SA offers an elegant and efficient solution and thus complies with the new Federal Ordinance on Noise Protection (OPB), which regulates the sound insulation of buildings.

Classification

Sonaspray is classified in the RF2 fire resistance classes.

Sprayed acoustic coating / Sonacoustic

Composition

Consists of a mineral wool board and two layers of acoustic coatings.

Scope of application

Sonacoustic is a smooth decorative product with high sound absorption for ceilings and walls.

Good acoustics is extremely important for the perception and use of a room. Whether it is a concert hall or a hotel lobby, in all these places, sound absorption is crucial for a good acoustic environment.
Sonacoustic covers the ceiling and walls with a highly soundproof and decorative layer.

The surface can be finished, completely smooth or with a light structured spray.

Sonacoustic is applied by panel installation and then by projection.
Sonacoustic is an ideal solution for public places, libraries, places of worship, concert halls, rest rooms, fitness centres or theatres.
