Where noise reverberation is a problem SonaSpray K-13 special acoustic ceiling and wall finish can be tailored to meet your specific project acoustic needs. There is a choice of finish; you may select texture, colour and acoustic performance. SonaSpray K-13 Special acoustic ceiling and wall finish can be applied at variable thickness and variable area to provide a designed acoustic ambience. It is spray applied to the full thickness in one application.

Test DATA certified by TNO Technical University Delft NL. SonasSpray acoustic ceiling and wall finish tests were on a solid backing. A panel backing with air space behind the panel will change absorption; normally there is improved absorption at low frequency. Substrates likely to provide increased performance include plasterboard with the use of an air gap behind, rib deck or profiled metal sheet. Please contact Oscar Acoustics’ technical department for free assistance.
The SonaSpray range contributes towards many sustainable design and health certification systems including BREEAM, SKA, Living Building Challenge and adds up to 17 points towards the LEED (Leadership in Energy and Environmental Design) rating of a project.
The SonaSpray range achieves M1 certification as Low Emitting Building Materials. This is the best possible classification.

The range is also covered by an Environmental Product Declaration in accordance with ISO 14025 and meets the requirements of the Living Building Challenge and LEED.
Achieves Cradle2Cradle and contributes towards satisfying many features under the WELL Building Standard®.
Made of fire treated, recycled paper and other rapidly renewable natural resources, SonaSpray can effectively lower the carbon footprint of the building project by sequestering rich stores of carbon for the life of the structure or application.
Oscar Acoustics have taken steps to reduce our environmental impact and demonstrate our commitment to protecting the environment by achieving ISO 14001 certification.
ISO 9001: 2000 certification
- SonaSpray is manufactured by ICC to ISO 9001.
- Installed using a four stage Oscar Acoustics quality assurance plan.
Oscar was established in 1978; this experience enables us to provide a well detailed, quality installation that stands the test of time. From specification to installation, everything is kept in-house. Oscar Acoustics only use qualified in-house operatives who specialise in installing our systems to ensure high standards are maintained.
- BIM Objects available for every product.
- All products are included within all current NBS software.
- Recessed and surface mounted items possible – see website for more information.
- Standard detail drawings for most situations.
- Bespoke detailing solutions possible.
SonaSpray acoustic ceiling and wall finish insulates by creating dead air spaces macroscopically between and within the hollow cellulose fibres. Testing on actual buildings demonstrates that sprayed insulation outperforms fibreglass bats that are mechanically retained. 100mm thick U = 0.32 W/m2K
For areas such as indoor pools and ice arenas, SonaSpray K-13 Special aids in condensation control. The proper combination of SonaSpray K-13 Special and ventilation prevents condensation on metal, concrete and other surfaces. SonaSpray K-13 Special reduces ventilation requirements, saving in both the ventilation equipment investment operating costs.
- Dry Weight of SonaSpray K-13 Special per 10mm thickness = 0.90 kg/m2
- Wet Weight of SonaSpray K-13 Special per 10mm thickness = 1.72 kg/m2
- Dry Weight of SonaSpray K-13 Special per 20mm thickness = 1.80 kg/m2
- Wet Weight of SonaSpray K-13 Special per 20mm thickness = 3.44 kg/m2
SonaSpray K-13 Special acoustic ceiling and wall finish can be applied to virtually any substrate; some surfaces may need priming to control suction. Old surfaces may need a barrier coating to prevent staining from leaching out contaminants while the surface is wet. Fully cured SonaSpray K-13 Special will improve strength as well as reducing noise reverberation.
The adhesive used with SonaSpray K-13 Special acoustic ceiling and wall finish provides a strong, durable and resilient bond. When fully cured, surface strength of old plaster will typically improve.
Recessed services e.g. spot lighting will require a halo spacer to match the material depth. Oscar Acoustics manufacture and install stainless steel halo spacers (drawing available) to the same size as the hole cut out. Stop beads may be required around openings which again we can supply and install. Specially designed access hatches are also available through Profab, enabling the SonaSpray to continue across the hatch door. Problems can arrise from using other hatches. These items are at extra cost and are to be purchsed direct from the Profab. Please contact Oscar Acoustics for details and item code. Surface mounted fittings e.g. hanging/pendant lights will require pattresses to match the material depth. Please contact Oscar Acoustics for further advice.
Please Note: 90% of flangeless fittings do not work properly with any acoustic finish. If you are specifying a flangeless fitting, please contact Oscar Acoustics for advice.
SonaSpray K-13 Special acoustic ceiling and wall finish can be quickly and effectively applied to any prepared surface and construction configuration where noise reverberation is a problem. This allows minimum working down time in existing structures with abilities to meet critical deadlines in new construction. SonaSpray K-13 Special has a medium surface texture and is suited to reducing noise reverberation in large rooms and halls. When applying to walls, position acoustic finishes above head height. For lower walls or areas of high impact, see EchoCheck acoustic blocks.
Other SonaSpray products offer a finer surface texture.
Please note that it is important not to use moisture resistant plasterboard as this can cause staining of wet applied products. Oil based stain barrier paints can be used to prevent this. Please consult Oscar Acoustics for more information.
A minimum of 12.5mm thick plasterboard, installed to British Gypsum specification should be used.
SonaSpray K-13 Special acoustic ceiling and wall finish can be over-painted (consult Oscar Acoustics technical department before painting as noise reverberation controlling properties can be significantly reduced if applied incorrectly), or applied with additional coats of SonaSpray. Small areas of damage can be repaired by hand.
If SonaSpray K-13 Special acoustic ceiling and wall finish is disturbed or damaged so that fibre is released into the atmosphere, the resulting contamination is harmless. Maintenance work can be undertaken while the building is occupied. Please refer to COSHH data for detailed product analysis.

variety of acoustic spray colours available
Available in a range of standard colours from stock, SonaSpray K-13 Special can also be manufactured to the client’s colour requirement (minimum quantity applies).
SonaSpray K-13 Special is a total acoustic spray system, with in-built treatment for fire and mould resistance; coloured through the full thickness of the coating. Manufacture is accredited ISO 9001:2000 certification.
SonaSpray K-13 Special was developed for installations where the standard SonaSpray K-13 surface was considered to be too coarse. SonaSpray K-13 Special has a finer texture and is an attractive surface finish in new build and renovation projects.
