In today’s architecture, designers are expected to create spaces that are both beautiful and functional. As open-plan layouts, exposed structures, and hard surfaces continue to define modern design, managing acoustics without compromising aesthetics has become a central challenge. Achieving this balance demands materials that perform acoustically while integrating seamlessly with the architectural vision.
That’s where Oscar Acoustics’ SonaSpray® range comes into its own.

Design freedom without compromise
Unlike rigid conventional acoustic panels and tiles, SonaSpray® is a spray-applied acoustic finish that follows the contours of the architecture, whether that’s a sweeping vault, a complex soffit, or a smooth, minimalist ceiling. The result is a seamless, monolithic surface that absorbs unwanted reverberation while preserving every design detail.
For architects, SonaSpray® offers something rare: true creative freedom. It can be tinted to any colour, and comes in a range of textures, from plaster-smooth elegance to a coarse, industrial finish, adaptable to virtually any substrate. Whether in a heritage conversion or a high-end workplace, SonaSpray® quietly enhances the space acoustically, allowing the architecture to take centre stage.

Safety and performance built in
Behind its seamless surface lies robust safety performance. The range exceeds the latest fire requirements set under the updated Fire Safety: Approved Document B, achieving Class 0 to BS 476 and B-s1,d0 fire ratings. This ensures that safety, aesthetics, and compliance are built into every specification, without the need for additional coatings or treatments.
In terms of noise control, SonaSpray® absorbs sound rather than reflecting it, creating interiors that are acoustically balanced and supportive of wellbeing, productivity, and concentration. Its versatility allows it to perform equally well in the lively atmosphere of a restaurant, the focused environment of a lecture theatre, or the collaborative energy of a co-working space.

A sustainable approach to acoustics
Environmental responsibility has been a cornerstone of Oscar Acoustics’ philosophy for almost five decades. Made from rapidly renewable resources that sequester carbon and water-based adhesives, the SonaSpray® range contributes to BREEAM, LEED, SKA and Living Building Challenge targets. Its ultra-low VOC content is GREENGUARD Gold certified, supporting healthy indoor environments.
As building performance standards evolve, this blend of design, safety, and sustainability has made SonaSpray® a trusted choice for leading architects and contractors. It has been specified in some of Britain’s most ambitious projects, including Google, Amazon, Barclays, Warner Bros, Microsoft, Apple, Twickenham and many more.

Quiet confidence
For architects seeking a finish that complements, rather than compromises, design intent, SonaSpray® offers a rare balance of aesthetic harmony, acoustic performance, and environmental responsibility. It proves that effective acoustic comfort can be achieved quietly through intelligent design and seamless integration.
