Acoustic spray foam systems for walls
The exterior walls (facades) of a building can be insulated acoustically to prevent outside noise from penetrating the building. The acoustic comfort inside a building is key for the well-being of its occupants.
To get the required performance, according to regulations and the desired interior comfort level, Synthesia Internacional has produced “Phono Spray S-904“. It is an open-cell, low density polyurethane system for thermoacoustic, airborne sound insulation for facades and interior walls.
Acoustic solutions for facades
For facades, we combine a layer of waterproof closed-cell polyurethane foam – Poliuretan S Spray foam, with a layer of open-cell Phono Spray S-904 thermoacoustic foam, thereby achieving a unique waterproof and thermoacoustic continuous solution applied in-situ. This provides an acoustic insulation level of between 45 and 60 dBA.

Acoustic solutions for interior walls
Phono Spray S-904 can also be applied in interior walls and partitions of houses and office buildings and other sectors. The application of acoustic insulation gives privacy and improves habitability.
Phono Spray S-904 can be applied to both masonry and dry lining structures.
Phono Spray S-904 in masonry achieves air sound insulation between 46 to 60 dBA.
Phono Spray S-904 in dry lining achieves air sound insulation between 37 and 45 dBA.
