technical specifications
Our SonaSpray range exceeds the latest fire requirements set under the updated Fire Safety: Approved Document B.
European fire test by Efectis Nederland:
B – s1, d0
UK fire test by Warrington fire research:
Class 0 to BS476 Part 6
Class l to BS476 Part 7
Full fire test reports available on request. Important Note: Always insist on obtaining a copy of the fire test report before using a product.
Its Class 0 to BS476 and B-s1,d0 fire rating provide significant benefits over the new Approved Document B requirements by providing little to no smoke and absolutely no droplets, assisting in the safe escape of occupants.

SonaSpray fcx installations are tailored to meet your specific projects architectural acoustic needs. There is a choice of finish and acoustic performance. Special colours can be manufactured for larger installations or for most applications the standard white RAL9010 finish can be refinished with water-based paint. SonaSpray fcx may be applied at variable thicknesses and areas to provide designed acoustic ambience. It is spray and trowel applied, building to the full thickness in one application.

Acoustic testing has been carried out against concrete. Substrates likely to provide increased performance include plasterboard with the use of an air gap behind, rib deck or profiled metal sheet. Please contact Oscar Acoustics’ technical department for free assistance.
Test DATA certified by TNO Technical University Delft NL. Tests were on a solid substrate. A panel substrate with air space behind the panel will change absorption; normally there is improved absorption at low frequency giving further flexibility in the design of architectural acoustics.
The SonaSpray range contributes towards many sustainable design and health certification systems including BREEAM, SKA, Living Building Challenge and adds up to 17 points towards the LEED (Leadership in Energy and Environmental Design) rating of a project.
The SonaSpray range achieves M1 certification as Low Emitting Building Materials. This is the best possible classification.

SonaSpray finishes are compliant with CDPH/ CA Section 01350 and are GREENGUARD Gold Certified for Indoor Air Quality. GREENGUARD Gold Products are now confirmed to show compliance with BREEAM rating system HEA Indoor Air Quality and ensure that a product has met some of the world’s most rigorous and comprehensive standards for low emissions of VOC’s into indoor air. The range is also covered by an Environmental Product Declaration in accordance with ISO 14025 and meets the requirements of the Living Building Challenge and LEED.
Made of fire treated, recycled paper and other rapidly renewable natural resources, SonaSpray can effectively lower the carbon footprint of the building project by sequestering rich stores of carbon for the life of the structure or application.

Oscar Acoustics have taken steps to reduce our environmental impact and demonstrate our commitment to protecting the environment by achieving ISO 14001 certification.
ISO 9001: 2000 certification
SonaSpray is excellent at thermally insulating by creating macroscopic air spaces between and within the cellulose fibres. U-Values can be adjusted to your projects exact requirements by adjusting the spray material depth. SonaSpray insulates by creating dead air spaces macroscopically between and within the hollow cellulose fibres.
Dry weight 4.50kg/m2 at 20mm thick.
SonaSpray fcx 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 fcx will not only improve the architectural acoustics but improve the strength of the substrate.
The adhesive used with SonaSpray provides a strong, durable and resilient bond. Fully cured SonaSpray can improve the composite 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.
Any interior space requiring improved architectural acoustics; SonaSpray fcx can be quickly and effectively applied to most prepared surface and construction configurations helping to achieve minimum working down-time in existing structures, with abilities to meet critical deadlines in new construction. SonaSpray fcx trowelled finish has a durable, flat pitted surface and is suited to walls and ceilings in restaurants (see photos), offices, public buildings, hotels, shopping complexes, conference rooms, large domestic rooms and indoor pools.
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.

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.
SonaSpray fcx can be over-painted or applied with additional coats of SonaSpray. Small damage can be repaired by hand. If SonaSpray fcx 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.
versatile acoustic design
SonaSpray fcx is ideal for a wide range of interiors including offices, restaurants, hotels, swimming pools, and other public spaces where both design and acoustic performance matter. The acoustic plaster spray enables architects and designers to create modern, visually clean environments with superb sound absorption.
Our standard white finish can be over-sprayed in virtually any colour with minimal impact on acoustic performance.
Bespoke colours: Custom-tinted materials available (minimum order quantities apply).
Verified performance: Independent acoustic test data for painted finishes is available.
