Aisti Aalto® acoustic tiles are a Class A sound-absorbing ceiling tile made primarily from natural wood fibre. Developed as a bio-based alternative to conventional acoustic materials, it brings together high acoustic performance, fire safety and circular design in one simple solution built into every tile.
Aisti acoustic tiles are bio-based yet high-performing alternative for suspended ceilings, without green premium in pricing.

High performance – without a green premium in pricing.
Aisti acoustic tiles begin with responsibly sourced wood fibre. The core material, Chemi-Thermo Mechanical Pulp (CTMP), is produced without toxic substances. The lightweight structure weighs just 1.8 kg per square metre and delivers Class A sound absorption and B-s1, d0 fire safety and are free from plastic binders or mineral wool.
Aisti tiles are developed primarily for offices, education, healthcare and other non-residential environments. The portfolio includes suspended ceiling and wall solutions, available in selected colour options.
High technical performance, natural material choice and a competitive price level make sustainable construction accessible for everyday building.
In the event of fire, the treatment reacts to heat and forms a protective ceramic layer on the surface of the tile. This barrier protects the wood fibres, slows flame spread and supports the material’s B-s1,d0 fire classification.
Fire protection is built into the material, delivering durable performance. This patented solution is unique to Aisti.
What does baking a cake have to do with acoustic tiles?
In this video, Mikko walks you through Aisti’s unique manufacturing process.
Starting from spruce wood, the fibres are pulped, mixed with water and a foaming agent, and transformed into a light, bubbly happiness material. As the mixture dries, natural hydrogen bonds form, creating a strong structure without plastic binders.
The tiles are then moulded, fire-protected with potassium based salt, and finished with fabric, paint, or print. Best of all, the material is easy to recycle, as it can be returned to the factory and pulped again.
A simple process. Simple product. Sustainable acoustics.

Aisti uses foam-forming technology – a foam-based process where millions of tiny bubbles distribute fibres evenly, creating a lightweight, porous structure that absorbs sound naturally.
If you believe sustainability and performance are inseparable, you’re in the right place, so do we. Aisti acoustic tile isn’t just another tile – it’s part of a new chapter in construction.
Aisti develops renewable acoustic materials for modern construction. Combining industrial scalability with material innovation, we make sustainable choices commercially viable. Changing construction for good.
