Our contribution is excellent room acoustics.

For excellent room acoustics, it's not just about a high αw-value; effectiveness across the relevant frequency ranges is what truly matters.

Our products, like Acospray DC3, achieve an αw-value of 0.45 at just 10 mm and αw = 1.00 at 35 mm. We deliver outstanding performance with minimal space requirements, providing an excellent foundation to comfortably meet the new SIA Standard 181/1 for Room Acoustics (effective from 2026).

The result: less reverberation and excellent intelligibility – even in demanding environments like restaurants, studios, or conference rooms.

Whether invisible in a minimalist design or a striking design statement – our acoustic spray plaster adapts to any architectural vision. It's freely customizable in shape, color, texture, and contour: from seamless ceilings and soft vaults to complex geometries. Surfaces can appear smooth, granular, mineral, or deep black, depending on the room concept. Feel free to browse our references and samples for inspiration.

It's ideal for new builds as well as renovations, where the acoustics seamlessly integrate into existing structures. Create unique spaces, from private rooms, offices, hotels, and hospitality venues to hospitals, sports halls, and industrial buildings. We ensure they are as acoustically impressive as they are visually.

Our acoustic spray plaster is made from 100% recycled cellulose. The material used is, in turn, fully recyclable, completely plastic-free, and based on natural substances. It's produced in Central Europe with minimal energy consumption.

We are Cradle2Cradle Certified® (Bronze) and are committed to continuously improving our sustainability standards. This way, we combine top acoustic performance with ecological responsibility – ensuring that pleasant-sounding spaces also have a good future.

Our acoustic solutions can be safely used in all spaces and meet stringent safety requirements. With a classification of RF2 / B–s1, d0, our material is flame-retardant, exhibits minimal smoke development, and prevents burning droplets in an emergency. These certified properties ensure that fire protection regulations are reliably met. Please note, however, that for areas with the highest non-combustibility requirements (RF1), such as certain core zones of escape routes, specialized solutions are required.

Beyond fire protection, our acoustic spray offers crucial advantages in terms of structural safety: Thanks to its extremely low self-weight (a mere 1.3 - 1.8 kg/m² per 10 mm thickness), the ceiling structure is barely stressed. Despite this lightness, the material boasts outstanding adhesive tensile strength, capable of withstanding 736 times its own weight. Furthermore, due to its high elasticity, the composite remains stable and crack-free even with slight movements of the building structure.

Our solutions thus make a significant contribution to comprehensive building safety while simultaneously supporting the functional design of excellent room acoustics.

Our acoustic systems don't just create quiet spaces; they also foster a healthy indoor climate. Thanks to their breathability, they naturally regulate humidity, support thermal insulation, and prevent mold growth. The surfaces are anti-allergenic – dust, bacteria, and microorganisms simply can't get a foothold.

With an M1 emission class rating, we are emission-free and meet the strictest health standards.

We believe in true value: Our acoustic systems range – depending on the material, layer thickness, and building conditions – between CHF 80 and CHF 200 per m².

Thanks to their long lifespan, minimal maintenance, and easy repair, the costs are unbeatable, even over the entire service life (Total Cost of Ownership). This means: invest once, benefit for a long time.

Our solution remains stable, functional, and visually high-quality – for decades. If damaged, repairs are very simple – easier than with a plasterboard ceiling. With our acoustic spray plaster, you secure long-term acoustic excellence and cost-efficiency.

Our acoustic spray plaster consists of cellulose fibers and a water-based binder. It's a lightweight material (approx. 1.2 kg/m² at 10 mm) with an impressive adhesive strength 736 times its own weight.

Its elastic structure prevents cracking and adapts to the movements of building components. At the same time, the surface is UV-resistant, color-stable, and diffusion-open, contributing to a consistent appearance and a healthy indoor climate. Free from harmful additives, the material choice stands for safety, sustainability, and building physics excellence.

Our acoustic spray systems adhere to almost any substrate – be it concrete, wood, plaster, metal, and much more. Application is done via spray technique directly onto the existing substrate. We don't need any complicated substructure.

Thanks to simple installation and quick drying within a few days, we support very short construction times. With dehumidifiers, drying can be shortened to as little as 2 days if needed.

Our warehouse in Switzerland and our Swiss team ensure immediate availability, flexible scheduling, and flawless execution.

We also implement extensions, phasing, or repairs quickly and straightforwardly.

Our acoustic surfaces are extremely low-maintenance. Dirt and grime can be easily removed without affecting their performance.

In case of damage, we can specifically repair partial areas – quickly, cleanly, and visually flawlessly. The durable materials withstand everyday stresses for many years. This saves you effort, costs, and time in maintenance, while the acoustic quality is permanently preserved.
