deliberately industrial acoustic spray

SonaSpray K-13 is a deliberately industrial decorative acoustic spray that absorbs sound energy instead of reflecting it, reducing reverberation times and overall noise levels within a space. SonaSpray K-13 acoustic spray can be applied directly to most substrates including concrete, plasterboard, GRP, steel, glass, expanded polystyrene and more. Any shaped substrate can be sprayed with SonaSpray K-13 including domes, vaults, profiled, corrugated, flat.

All our acoustic products are installed by our specialist in-house teams and we cover the whole of Great Britain. Get in touch with our acoustic experts today to discuss your project requirements.

SonaSpray K-13 can be tailored to meet your specific project acoustic needs. There is a choice of finish and you can select texture, colour and acoustic performance. SonaSpray K-13 can be applied at variable thickness and variable areas to provide a designed acoustic ambience. It is spray applied to the full thickness in one application.

For the ultimate acoustic combination in sports halls, use SonaSpray K-13 on standard plain non-perforated deck with the new Oscar Evo-Panel at low level. The Oscar Evo-Panel is the first acoustic panel designed specifically for use at low level in high impact areas. Positioning these at low level prevent sound flutter off lower walls meaning you require 35% less Evo-Panels than standard acoustic panels at high level. Sport England compliant.

“Changing spec from standard acoustic panels at high level and replacing perforated metal deck in our sports hall with plain galvinised metal deck treated with SonaSpray K-13 has saved us a fortune & time in the programme. Everyone has commented on how quiet the sports hall is now”.

Test DATA certified by TNO Technical University Delft NL. 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.

SonaSpray insulates by creating dead air spaces macroscopically between and within the hollow cellulose fibres. Testing on actual buildings demonstrates that sprayed insulation outperforms fibreglass batts that are mechanically retained. 100mm thick U = 0.32 W/m2K.

For areas such as indoor pools and ice arenas, SonaSpray K-13 aids in condensation control. The proper combination of SonaSpray K-13 and ventilation prevents condensation on metal, concrete and other surfaces. SonaSpray K-13 reduces ventilation requirements, saving in both the ventilation equipment investment operating costs.

  • Dry Weight of SonaSpray K-13 per 10mm thickness = 0.72 kg/m2
  • Wet Weight of SonaSpray K-13 per 10mm thickness = 1.37 kg/m2
  • Dry Weight of SonaSpray K-13 per 20mm thickness = 1.44 kg/m2
  • Wet Weight of SonaSpray K-13 per 20mm thickness = 2.74 kg/m2

SonaSpray K-13 noise reduction insulation 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 whilst the surface is wet.

Standard Colours: (s) = Stock (ns) = Non-Stock

SonaSpray fcx: Arctic White (s), White (ns)

SonaSpray fc: Arctic White (s), White (ns), Black (ns)

SonaSpray K-13 Special: White (s), Light Grey (s), Grey (s), Dark Grey (ns), Black (s), Beige (ns), Tan (ns)

SonaSpray K-13: White (s), Light Grey (s), Grey (s), Dark Grey (ns), Black (s), Beige (ns), Tan (ns)

Bespoke colours are manufactured to order. Minimum order quantities apply and square meterage is dependent on the product and thickness of spray. Please send us your colour requirement using a Dulux paint reference and we will respond with quantity, price and colour samples.

The adhesive used with SonaSpray K-13 noise reduction insulation provides a strong, durable and resilient bond. When fully cured, surface strength of old plaster will typically improve. Fully cured SonaSpray K-13 can improve strength.

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 noise reduction insulation can be quickly and effectively applied to any prepared surface and construction configuration. This allows minimum working down time in existing structures with abilities to meet critical deadlines in new construction. SonaSpray K-13 has a coarse surface texture and is suited to large buildings with longer viewing distances; or use close up where a strong texture is required. Other SonaSpray products offer a finer surface texture. SonaSpray K-13 is also ideal in some cases for rain noise reduction within the building.

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.

Category_IIAs a protective coating to delay the ignition and reduce the surface burn rate of combustible wood and cellulosic fibre building material.
Category_IIIAs a protective coating to delay the ignition and reduce the surface burn rate of low melting point, combustible cellular plastic building materials and to protect their dimensional stability for a brief period.
Category_IVAs a protective coating for building structural steel, to supplement automatic sprinkles protection in preventing structural failure temperatures of the steel in high fire hazard occupancies.
Category_VAs a protective coating to the underside of a Class II insulated steel roof deck construction, to sufficiently lower the rate of fuel contribution from the Class II deck components to qualify the construction as Class I so allowing automatic sprinkler protection to be omitted under Factory Mutuals Standards.

SonaSpray K-13 noise reduction insulation can be over-painted or applied with additional coats of SonaSpray. Small areas of damage can be repaired by hand.

If SonaSpray K-13 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.

SonaSpray K-13 vs. Sprayed Fiberglass VIDEO – a comparative fire endurance test

This test was conducted to evaluate the fire performance and endurance qualities of two different spray applied materials used as exposed thermal and acoustical finishes. The test materials were SonaSpray K-13, a cellulose material, and sprayed fiberglass. The test was conducted using the ASTM E-119 Standard for Fire Tests of Building Construction and Materials.

what our customers say

Quote Icon

“Everyone loves the SonaSpray finish! Second to the exterior thatch, it is the most asked about and photographed material in the building.

During our regular tours, people are always asking what it is and what it is for. They love that fact that it has a purpose and is on show so they can see how the building works.”

Fergus Rolfe, Team Manager, The Enterprise Centre, UEA – SonaSpray

“Having used SonaSpray on several other projects, we knew how effective it was at reducing office noise. It’s quickly become our go-to product and our clients are always happy to follow our recommendations due to the huge difference it makes, both in open-plan areas and cellular spaces.

Having used a competitor product recently, we noticed a drop in standard and only SonaSpray delivers both in terms of aesthetics and sound management. The finish on the project was exceptional and hides any imperfections, making it as visually strong as it is at reducing noise.”

Mariachiara Dal Pozzo, Associate Director, TP Bennett

“We are really happy with the results in Studio 3 from both an acoustic point of view and aesthetically, it’s exactly what we were looking for. I would also like to say thanks to the guys who were top notch – very courteous and professional and extremely tidy. Great job all round, really appreciate it. ”
