SonaSpray K-13 Installations

Investec

Investec

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 current office acoustics issues. 

Bath College Construction Skills Centre

Bath College Construction Skills Centre

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.  

Notting Hill Prep School - Westway

Notting Hill Prep School - Westway

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.

Dome & O2 Arena, Greenwich, London

Dome & O2 Arena, Greenwich, London

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.

Byron Burger, Piccadilly Gardens, Manchester

SonaSpray K-13 in black applied to the soffit at the Byron Burger restaurant in Piccadilly Garden, Manchester to control reverberation and refurbish the old ceiling. 

The Enterprise Centre - University of Anglia

The Enterprise Centre - University of Anglia

Dubbed by the press as the UK's greenest buidling, The Enterprise Centre at the University of East Anglia was designed and delivered by Architype and Morgan Sindall Construction to achieve the Passivhaus standard and a BREEAM outstanding rating. SonaSpray K-13 noise reduction insulation acoustic spray applied in light grey and white throughout the project contributed to this perfectly.

House of Blues, Chicago

House of Blues, Chicago

The House of Blues features a large stage with elaborate sound and lighting and a restaurant. For perfect club acoustics, SonaSpray K-13 Black noise reduction insulation was sprayed to the concrete ceiling which rises more than 12 metres above the floor of the club. 

Manor Drive Methodist Church

Manor Drive Methodist Church

Following the removal of asbestos in the dome and vaults, the church acoustics deteriorated dramatically. Worshippers complained they were having difficulty in hearing and understanding services due to sound reflecting around the room, a common problem in large and hard walled buildings like churches. 

The Royal Observatory

The Royal Observatory

The home of time itself. The Royal Observatory is one of the most important historic scientific sites in the world.  Founded by Charles II in 1675 it is known throughout the world as being the official starting point for each new day, year and millennium.

House of Blues

House of Blues

The House of Blues concert hall is the brainchild of Isaac Tigrett, an entrepreneur who launched his successful career with the opening of the first Hard Rock Café in London at the age of twenty two. His first House of Blues concert hall opened in Boston to an enthusiastic response and other clubs quickly followed. Chicago’s House of Blues, in particular, captures the flavour of the city’s legendary blues status whilst introducing sophisticated sound, light and club acoustic technology for an exciting atmosphere.

King Ethelbert School

King Ethelbert School

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.

Acoustic DATA:

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".

Ideal for rain noise reduction

Environmental

SonaSpray K-13 achieves M1 certification for Building Material emissions. This is the best possible classification. Click here for certificate.

Thermal DATA

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

Mass

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

Bonding to substrate

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.

Condensation control

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.

RH control

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.

Durability

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 items

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.

Where to use

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.

Category_V As 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.

Maintenance

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.
