Why It Matters

Create Calm
and Inviting Spaces

Every room has an acoustic signature: the echo in a lobby, the reverberation in an open-plan office, the harsh reflections off a concrete ceiling. Senza’s acoustic plaster rewrites that signature at the source.

Reducing echo, reverberation, and noise pollution: sound is absorbed at the wall or ceiling plane instead of bouncing back into the room.

Natural & Sustainable Materials

Natural & Sustainable
Mineral Materials

A high-end finishing system for walls and ceilings that combines sound-absorbing fibrous and porous materials.

Senza acoustic plaster is built from natural mineral materials rather than synthetic foams or petroleum-based binders.

That combination of performance and material integrity is exactly why architects, interior designers, commercial developers, general contractors, and luxury homeowners increasingly specify acoustic plaster over conventional acoustic panels or ceiling tile.

Acoustic Performance

Acoustic Performance

Senza acoustic plaster reduces sound reflection and noise levels by converting sound energy into heat. The finish coat is engineered to let sound pass through, where it attenuates within the mineral wool layer beneath.
