Spray-on decorative sound absorber
SonaSpray fc is a one coat, seamless, decorative sound absorber that is spray applied to virtually any clean surface and any shape of surface. It has a lightly textured and firm finish.
SonaSpray fc sound absorbing spray will conform to most surface contours. In addition to flat surfaces it can be applied to: barrel vaults, domes, corrugated decks, pan construction and other complex surfaces.
The high performance adhesive will bond to virtually all common construction materials including plaster, wood, metal and concrete.
Some surfaces, such as water stained ceilings, wood and oxidized metal, will require sealing to prevent migratory staining of the SonaSpray finish. SonaSpray fc acoustic spray can be installed where panels or stretch fabrics are impossible and even with thin coatings is an excellent sound absorber.
Features of SonaSpray fc sound absorbing spray
- Achieves M1 certification for Building Materials emissions.
- Acts as the perfect sound absorber for buildings by absorbing sound energy instead of reflecting it, thereby reducing reverberation times and overall noise levels.
- Can contribute up to 17 points to the overall LEED (Leadership in Energy and Environmental Design) rating of a project.
- The adhesive provides a strong, durable and resilient bond.
- Can be applied to virtually any substrate configuration.
- Aids in condensation and humidity control by absorbing large amounts of water vapour and releasing it when humidity levels drop, promoting a healthy and balanced atmosphere.
- Insulates by creating dead air macroscopic spaces between and within the hollow cellulose fibres.
- Spray directly onto plasterboard, concrete, steel sheet and most other surfaces.
Listen to the amazing results!
SonaSpray fc is the sound absorber finish that transforms a noisy, reverberant space into a pleasant acoustic ambience with clarity of speech and music.
Typical SonaSpray fc sound absorber applications include:
Safe • Recycled • Natural cellulose fibre • Natural sound absorbing
Future reconstruction of buildings may require the removal of SonaSpray sound absorber. It can be recycled or disposed of as a non-special waste and your local authority environmental department will give advice on recycling.
What people say about our SonaSpray fc sound absorber spray applications...
“I am writing to congratulate your company for the success achieved in the reduction of the noise level in our school dining room when 200+ children are having their lunch. Prior to the application of SonaSpray fc the noise level was deafening and now it is possible to talk to ones neighbour in a normal voice when lunching at the staff table. We shall certainly use you again in certain other school rooms where the noise levesl are high or the acoustics are poor.

SonaSpray fc Installations
SonaSpray fc acoustic spray and sound absorber in arctic white was applied directly to finished concrete throughout the atrium, seminar rooms and lecture theatres in Blavatnik School of Government in Oxford for perfect university acoustics.
With its student population increasing rapidly, University College London (UCL) required more space on its campus in Bloomsbury. Working with the University’s Design Team, Structure Tone helped develop a scheme to refurbish the ground floor and basement and also renovate Level 10 at Torrington Place.
The large, open plan design of Leicester University’s new Student Union building meant that in order for it to be fit for purpose, i.e. a relaxing space to meet socialise and study, some kind of sound absorber was going to be needed. Options were limited due to the half glazed and half curved feature sail design of the ceiling.
SonaSpray fc in white applied to a ceiling surface is an ideal sound absorber and also helps to reduce condensation in the pool area when it is combined with appropriate ventilation. SonaSpray fc will provide the pool with a bright, attractive ceiling for years to come.
During 2000, following the repositioning of the main stage at the original Wembley Stadium, concert goers complained to the management about poor stadium acoustics spoiling their enjoyment of the concert.
A recent major refurbishment to this grade II* listed building included improvement to the church acoustics. After research by acoustic consultants - Peninsular Acoustics - an acoustic coating of SonaSpray fc sound absorber in off white was proposed at 25mm thickness to control reflected noise from hard surfaces.
Emlyn Hughes House is designed to provide drama both from the exterior and interior. The Gateway Project was intended to represent the history of the town by resembling a submarine, construction of which is the towns primary industry.
When BT Groups, 19th Century Faraday Building in the City of London received a major refurbishment the main contractor was looking for a decorative coating that would refurbish the old existing concrete soffit using a single coat.
SonaSpray fc Technical Specification
SonaSpray fc installations 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 fc can be applied at variable thicknesses and variable areas to provide designed acoustic ambience. It is spray applied to the full sound absorber thickness in one application.
SonaSpray fc standard absorption coefficients
Test DATA certified by TNO Technical University Delft NL. Tests were on a solid backing. A sound absorbing fc panel substrate with air space behind the panel will change absorption; normally there is improved absorption at low frequency.
SonaSpray fc achieves M1 certification for Building Material emissions. This is the best possible classification. Click here for certificate.
SonaSpray insulates by creating dead air spaces macroscopically between and within the hollow cellulose fibres.
Dry Weight of SonaSpray fc per 10mm thickness = 1.60 kg/m2
Wet Weight of SonaSpray fc per 10mm thickness = 2.93 kg/m2
Dry Weight of SonaSpray fc per 20mm thickness = 3.20 kg/m2
Wet Weight of SonaSpray fc per 20mm thickness = 5.86 kg/m2
Bonding to Substrate
SonaSpray fc sound absorber 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 of contaminants whilst the surface is wet. Fully cured SonaSpray fc will improve strength.
|Bond Strength:||SonaSpray fc||>600 psf ASTM E-736|
|Compression Strength:||SonaSpray fc||>400 psf ASTM E-761|
The adhesive used with SonaSpray fc sound absorber provides a strong, durable and resilient bond. When fully cured, surface strength of old plaster will typically improve.
For areas such as indoor pools, SonaSpray fc aids in condensation control. The proper combination of SonaSpray fc and ventilation prevents condensation on metal, concrete and other surfaces. SonaSpray fc sound absorber actually reduces ventilation requirements, saving in both the ventilation equipment cost and operating costs.
SonaSpray fc is a natural humidity moderator. At times of increasing humidity SonaSpray fc will absorb large amounts of water vapour. When the humidity drops SonaSpray fc will exhale water vapour and maintain a balance. This characteristic promotes a healthy atmosphere.
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 purchased direct from the Profab. Please contact Oscar Acoustics for details and an 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.
Where to use
SonaSpray fc sound absorber can be quickly and effectively applied to most prepared surfaces and construction configurations. This allows minimum working down time in existing structures with abilities to meet critical deadlines in new construction. SonaSpray fc has a fine surface texture and is suited to ceilings of offices, restaurants, receptions, designer homes, school classrooms, swimming pools etc. in fact it is an excellent sound absorber for any premium indoor space with a noise problem.
