The exterior walls (facades) of a building can be well insulated acoustically to prevent outside noise penetrating the building. The acoustic comfort inside a building makes it healthier for its occupants.
To get the required performance, according to regulations and the desired interior comfort level, Synthesia Internacional have produced “Phono Spray S-904“. It is an open-cell, low density polyurethane for thermoacoustic, airborne sound insulation for facades and interior wall solutions.
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 in situ. This achieves an acoustic insulation level of between 45 and 60 dBA.

Acoustic solutions for interior walls
Phono Spray S-904 can also be applied in the 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.
