SonaSpray fc

 

Spray-on Acoustic 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 firm finish.

SonaSpray fc 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 can be installed where panels or stretch fabrics are impossible and even with thin coatings is an excellent sound absorber.

Safe, recycled, natural, sound absorbing cellulose fibre. Future reconstruction of buildings may require removal of SonaSpray sound absorber, it can be recycled or disposed of as a non-special waste - your local authority environmental department will give advice on recycling.

 

Typical SonaSpray fc sound absorber applications:

This sound absorber is suited to ceilings of: reception areas, schools, public buildings, auditoriums, offices, swimming pools, hotels, conference and board rooms.

SonaSpray fc Installations

University of Leicester

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 sort of sound absorber was going to be required.  Options were limited due to the half glazed and half curved feature sail design of the ceiling.

SonaSpray fc was specified for its high absorption, 80% light reflectivity, (brightening the space), and ability to follow the lines of the existing surface with a seamless finish, retaining the original exciting design features.

This sound absorber was applied directly onto plasterboard for main contractor,  Morgan Sindall in the main atrium to the feature curved sails and at low level above the surrounding balconies.  SonaSpray’s ability to follow exactly the lines of the existing surface, meant there was no need to compromise on design.

What would ordinarily be an extremely noisy, reverberant space is now a light and calm space in which it is a pleasure to spend time.


Holmes Place Fitness Centre Swimming Pool

SonaSpray fc in white applied to a feature wave design ceiling is an ideal sound absorber. SonaSpray fc offers other useful features; it is spray-applied and covers the wave design ceiling with a joint free monolithic coating. SonaSpray fc 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.

Superior acoustic control, a highly light reflective finish, the sound absorber with the ability to conform to any substrate configuration with an attractive, uniform texture make SonaSpray fc the best ceiling finish for new construction or renovation projects. Our range of sound absorber finishes offers the ideal ceiling treatment for most acoustic or thermal insulation requirements. Contact Oscar Acoustics for complete details on how SonaSpray can improve your building projects.

Acoustic DATA

SonaSpray fc installations can be tailored to meet your specific project acoustic need. There is a choice of finish; you may select texture, colour and acoustic performance. SonaSpray fc can be applied at variable thickness and variable areas to provide designed acoustic ambience. It is spray applied to the full sound absorber thickness in one application.

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.

Environmental

SonaSpray fc achieves M1 certification for Building Materials 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.

Mass

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 while 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

Durability

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.

Condensation Control

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.

RH Control

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 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 the Profab.  Please contact Oscar Acoustic for details and item code.  Surface mounted fittings e.g. hanging/pendant lights will require a pattresses to match the material depth.  Please contact Oscar Acoustics for further 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 rooms, swimming pools; in fact it’s an excellent sound absorber for any premium indoor space with a noise problem.

Fire Performance Ratings

UK Fire test by Warrington Fire Research:

  • Class 1 to BS476 Part 7
  • Class 0 to BS476 Part 6

Maintenance

SonaSpray fc sound absorber can be over-painted or applied with additional coats of SonaSpray. Small areas of damage can be repaired by hand. Maintenance of this seamless decorative sound absorbing finish is minimal.

If SonaSpray fc 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.
