This unique project is the first ever school building to be built under a motorway. The technical challenges were considerable and involved forming an independent, acoustically separated structure below the concrete framed Westway, next to the Hammersmith and City tube line. SonaSpray K-13 in mid-grey was applied onto concrete and plasterboard at 25mm thick to control reverberation, give clarity to sound and reduce overall noise levels.
SonaSpray K-13 applied over a reinforcement mesh during the refurbishment of the Winter Gardens Pavilion, Weston-Super Mare in order to acoustically treat and decorate. We have a range of 5 acoustic finishes from textured to the smoothest acoustic plaster available.

International Specialist Banking and Asset Management Group offices in the City of London received an office refurbishment in 2018. The fit out & refurbishment experts We Are BW were considering how to preserve the existing rib deck ceilings with beams throughout whilst solving the office acoustic issues. Our SonaSpray K-13 was applied throughout and is the perfect solution for reverberation control within offices.
6,200 m2 of SonaSpray K-13 in white applied to plasterboard and profiled deck at Cardiff Ice Arena for Kier Construction. SonaSpray aids in condensation and humidity control by absorbing water vapour then releasing it when humidity levels drop, promoting a healthy and balanced atmosphere. SonaSpray reduces ventilation requirements with potential savings in equipment and operating costs too.
SonaSpray K-13 in black was spray applied above slatted timber by one of our in house expert teams to acoustically treat the ceiling during this fit out of Arlington Business Park's ground floor and cafe by Bulb Interiors.
When The Millennium Dome made the change into the O2 Dome, there was a need once again for acoustic ceiling and wall treatment in some of the main public areas. Oscar Acoustics were already familiar with the Millennium Dome, having undertaken three separate projects for the original exhibition before.
The SonaSpray range has been included in some of the UK’s greenest projects, including The Enterprise Centre at the University of East Anglia, which was dubbed by the press as ‘the UK’s Greenest Building’. This project achieved Passivhaus standard, BREEAM outstanding rating and 31 accolades including RIBA Sustainable Project of The Year, BREEAM Awards Best Education Project and Passivhaus Trust Award.
SonaSpray K-13 noise reduction spray in black applied to the soffit at the Byron Burger restaurant in Piccadilly Garden, Manchester to control reverberation and refurbish the old ceiling.
This state-of-the-art construction skills centre at Bath College is a purpose-built facility accommodating new workshops that cater for 500+ apprentices and students studying bricklaying, construction, carpentry and stonemasonry, as well as plumbing, electrical installation and refrigeration. Without acoustic treatment the noise levels within these spaces would have been uncomfortably high whilst machinery was in use.
Each project is individual; for King Ethelbert School in Kent, acoustic measurements were taken and with purpose designed software an acoustic computer model of the sports hall was created. This enabled Oscar Acoustics to calculate which areas required treatment to achieve the desired school acoustics.
During the recent refurbishment of The Windsor Hall at the Bournemouth International Centre, improved auditorium building acoustics was a major requirement.
Sports hall acoustics are typically reverberant due to a combination of large areas of hard block walls, corrugated steel ceilings and wooden floors. To control a sports hall acoustics a large amount of acoustically absorptive material has to be applied around the hall. A spray-on material has a distinct advantage over acoustic panels in this situation.
Download BIM ObjectSonaSpray 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".

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. Fully cured SonaSpray K-13 will improve strength.
For areas such as indoor pools and ice arenas, SonaSpray K-13 noise reduction insulation aids in condensation control. The proper combination of SonaSpray K-13 and ventilation prevents condensation on metal, concrete and other surfaces. SonaSpray K-13 actually reduces ventilation requirements, saving in both the ventilation equipment cost and operating costs.
SonaSpray K-13 noise reduction insulation is a natural humidity moderator. At times of increasing humidity SonaSpray K-13 will absorb large amounts of water vapour. When the humidity drops SonaSpray K-13 will exhale water vapour and maintain a balance. This characteristic promotes a healthy atmosphere.
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.
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 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 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 flangless 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.
