Acoustic thermal insulation with a seamless and decorative finish

Sonatherm is a seamless, acoustic thermal insulation system for basement car parks, cantilever buildings, balconies, soffits of walkways and underpasses.  Sonatherm acoustic thermal insulation consists of foil-faced mineral wool slabs over-sprayed with a choice of SonaSpray acoustic spray finishes (see separate SonaSpray fc, SonaSpray K-13 special and SonaSpray K-13 standard products for details) to achieve a fire rating and aesthetic appearance.

By varying the thickness of the mineral wool slabs all permutations of acoustic thermal insulation are achieved.  The layer of SonaSpray also means that any sound is absorbed rather than being reflected, considerably reducing reverberation times and therefore reducing overall noise levels within the space.

Features and benefits of Sonatherm acoustic thermal insulation

  • Suitable for thermal acoustic sound insulation. Reconstruction of a building may necessitate the removal of the SonaSpray and mineral wool slabs components of Sonatherm. The SonaSpray component can be recycled or disposed of as a non-special waste to landfill.
  • Sonatherm acoustic thermal insulation is Building Regulations (E&W) Approved Document E compliant.
  • Thermal insulation with reverberation noise reduction.
  • Spray applied, one coat, decorative, thermal insulation finish with foil-faced mineral wool slabs substrate.
  • Seamless monolithic ceiling.

Other acoustic thermal insulation applications

Sonatherm thermal acoustic insulation can also be used for the soffits of walkways, underpasses and balconies.  In any area where it is protected from direct rain, architects can employ the insulating and acoustic properties of Sonatherm to the full.

Recyclable, low embodied energy & good for the environment

Sonatherm is perfect for thermal acoustic sound insulation.  Reconstruction of a building may necessitate removal of the SonaSpray and EPS components of Sonatherm.  The SonaSpray component can be recycled or disposed of as a non-special waste to landfill.

Repairing & servicing Sonatherm

Local repairs of small areas are performed by hand.  A wall or a ceiling can be entirely over sprayed in the same or a different colour.  It is also possible to spray with a water based paint - please contact our Oscar Acoustics technical department for further details.

Dust can be removed by blowing with an air pressure gun or by vacuuming with a soft brush attachment.
