Acoustic plaster

Acoustic plaster is a special, open-pored plaster that improves room acoustics through sound absorption, which reduces reverberation times and increases speech intelligibility. It converts sound energy into heat, is usually applied to walls or ceilings in several layers and offers a seamless, aesthetic alternative to acoustic ceilings. 

These are mineral plaster coatings that contribute to the absorption of airborne sound with their surface structure and grain composition. Added aggregates, such as expanded natural stone particles or mineral fine chips, play an important role in this.

Key features and benefits

• : Sound absorption: Reduces reverberation and creates a pleasant atmosphere.
• Seamless: Enables a visually appealing design of wall-to-wall ceilings.
• Versatility: Suitable for offices, restaurants, lobbies and living spaces.
• Functions: Can have a moisture-regulating effect (hygroscopic) and improve sound insulation in the room.
• Application method: Often applied as a spray plaster to achieve the required porosity. 

Areas of application:

• Large rooms with a lot of sound reflection.
• Ceilings and walls in modern, smooth interiors.
• Offices and public buildings for noise reduction. 

Acoustic plaster systems can also be used in combination with heating or cooling systems and are available in various colours and structures from smooth to coarse-grained. They are an effective way to reduce sound levels and increase well-being in rooms.
