sustainable acoustic spray solutions for low-carbon buildings
As sustainability targets tighten for buildings in the UK, architects and specifiers are under growing pressure to reduce carbon impact without compromising performance or design. Acoustic treatments are often overlooked in this conversation. However, they play a significant role in occupant health, wellbeing, comfort and overall building performance.
Sustainable acoustic sprays offer a practical way to control sound while supporting low-carbon building goals.
Oscar Acoustics’ range of acoustic spray systems balance acoustic performance, fire safety, design flexibility and environmental responsibility. The result is a range of solutions that help create calmer, healthier spaces while minimising environmental impact.
what makes an acoustic spray sustainable?
Not all acoustic products are equal. A genuinely sustainable acoustic spray should demonstrate performance across several areas:
- use of recycled or rapidly renewable materials
- low embodied carbon
- excellent indoor air quality credentials
- durability and long service life
- contribution to leading sustainability and wellbeing certifications
Our SonaSpray range has been developed with these principles in mind, combining proven acoustic performance with transparent environmental credentials.
recycled materials and carbon reduction
Setting new standards for sustainability, our SonaSpray range is manufactured using fire-treated recycled paper and other rapidly renewable materials such as cotton and hemp. By reusing these resources, this acoustic spray helps divert waste from landfills and reduces reliance on virgin materials.
There is also a carbon benefit. SonaSpray acoustic sprays sequesters carbon for the lifetime of the building, effectively locking it into the structure rather than releasing it back into the atmosphere. This makes acoustic spray an attractive option for projects aiming to reduce whole-life carbon impact.
SonaSpray Eco+ takes this a step further. Made from fire-treated recycled newspapers, it celebrates its recycled origins through a naturally varied grey finish, removing the need for additional colour refinement processes and further lowering environmental impact.
supporting green building certifications
Sustainable acoustic spray can make a meaningful contribution to widely recognised environmental and wellbeing standards. Oscar Acoustics’ SonaSpray range supports credits across multiple certification schemes, including:
- BREEAM
- WELL
- SKA
- the Living Building Challenge
- LEED, with up to 17 points achievable depending on project scope
These certifications increasingly influence planning decisions, funding, and the long-term value of your asset. Acoustic spray that supports these frameworks helps designers align acoustic performance with broader sustainability objectives.
indoor air quality and wellbeing of occupants
Low-carbon buildings are not just about energy and materials. Indoor air quality is equally important. Acoustic sprays are often applied across large ceiling or soffit areas, so emissions performance matters.
Our SonaSpray range meets strict global standards for low VOC emissions, including GREENGUARD Gold Certification, CDPH/CA Section 01350 compliance, M1 Low Emitting Materials rating and Cradle to Cradle Certification. This ensures acoustic performance without compromising the health of occupants, particularly in schools, offices, healthcare settings and other public spaces.
fire safety without compromise
Sustainability and safety must go hand in hand. Oscar Acoustics’ acoustic sprays exceed the latest fire requirements set under Approved Document B. Products within the SonaSpray range achieve Class 0 to BS476 and B-s1,d0 fire ratings, offering little to no smoke production and no flaming droplets.
This level of fire performance allows acoustic spray to be confidently specified in exposed soffit designs and open-plan interiors, where both acoustic control and safety are critical.
efficient installations and less waste
Acoustic spray systems are spray-applied directly to suitable substrates such as concrete, plasterboard, steel or timber. This reduces the need for complex framing systems, fixings or multiple material layers, helping to minimise waste on site.
Oscar Acoustics installs all acoustic spray systems using in-house specialist teams across Great Britain. This ensures consistent quality, efficient installation and fewer remedial works, further supporting sustainable construction practices.
a practical solution for modern low-carbon buildings
From commercial offices and hospitality spaces to education and public buildings, sustainable acoustic spray offers a flexible solution that supports modern architectural design. Unlike traditional rigid solutions, SonaSpray can be applied to almost any surface and is available in a wide range of textures and colours, either blending seamlessly or becoming a design feature.
Smooth finishes such as Oscar Elite acoustic plaster and SonaSpray fcx provide refined, seamless ceilings, while products like SonaSpray K-13 deliver lightly textured or deliberately industrial aesthetics without sacrificing environmental performance.
By combining recycled content, low emissions, fire safety and long-term durability, Oscar Acoustics’ acoustic sprays help architects meet both acoustic targets and sustainability ambitions.
building calmer, greener spaces with Oscar Acoustics
Sustainable design is about making informed choices that improve how buildings perform for people and the planet. Acoustic spray is one of those choices. With nearly five decades of experience, Oscar Acoustics continues to lead the way in sustainable acoustic innovation, enabling architects to create spaces that sound good, feel comfortable and stand the test of time.
For projects where acoustic performance, environmental responsibility and visual designs must work together, our acoustic sprays offer a proven, low-carbon solution.
