Acoustic Plaster

AcouStick Acoustic Plaster is a seamless, jointless acoustic ceiling and wall system built over a sound-absorbing mineral wool core and finished with a site-applied plaster coating.

The system creates a continuous monolithic surface without visible joints or a conventional suspension grid while providing sound absorption for interior spaces. Its flexible construction can follow curves, vaults, irregular geometry, and architectural profiles, making seamless acoustic plaster suitable for premium commercial, hospitality, cultural, educational, and public interiors.

Why Choose Acoustic Plaster?

Completely Seamless Surface

The system creates a continuous architectural surface without visible panel joints or a conventional exposed suspension grid, providing a clean and integrated finish.

High Sound Absorption

The mineral wool core provides the sound-absorbing layer behind the plaster finish, helping reduce reflected sound and reverberation within the treated space.

Flexible Architectural Design

The system can follow curves, vaults, irregular geometry, and other architectural profiles where conventional acoustic panels may be difficult to integrate.

Smooth Architectural Finish

The site-applied plaster creates a monolithic surface that can be finished from smooth to coarse-grained textures according to the design requirements.

Multiple Installation Systems

The system can be installed directly to a suitable substrate, mechanically fixed to a grid, or suspended depending on the project requirements.

Wide Range of Colours

A wide range of colour options is available, allowing the acoustic plaster ceiling or wall treatment to integrate with the architectural design.

How Does Acoustic Plaster Work?

Acoustic plaster combines a sound-absorbing mineral wool core with a site-applied plaster finish.

Sound waves reaching the surface interact with the acoustic system and pass into the sound-absorbing mineral wool layer, where sound energy is dissipated. This helps reduce reflected sound and reverberation while maintaining a continuous architectural surface.

Sound → Acoustic Plaster Finish → Mineral Wool Core → Sound Energy Absorption → Reduced Reverberation

The final acoustic performance depends on factors including the mineral wool thickness, plaster system, installation method, surface area, cavity configuration, and complete ceiling or wall assembly.

Acoustic Performance

Our sound absorption plaster systems are designed to provide acoustic absorption while maintaining a seamless architectural appearance.

Actual acoustic performance depends on the selected mineral wool, system thickness, installation method, cavity configuration, surface coverage, and complete system assembly. Project-specific acoustic test data should be referenced where required.

Acoustic Plaster Applications

Acoustic plaster systems are suitable for spaces where sound absorption needs to be combined with a seamless architectural finish.

Hotel Lobbies & Hospitality Interiors

Suitable for premium hotel spaces where acoustic treatment needs to be integrated into a clean architectural ceiling or wall surface.

Atriums

The seamless construction can be used in large-volume atriums where controlling reverberation is important while maintaining the architectural appearance of the space.

Auditoriums

Suitable for selected auditorium applications where sound absorption and controlled reverberation are required without visible acoustic panels.

Museums & Galleries

The continuous finish can integrate acoustic treatment into exhibition spaces while maintaining a minimal architectural appearance.

Showrooms

Suitable for premium commercial interiors where acoustic performance needs to be combined with a clean, uninterrupted ceiling or wall finish.

Places of Worship

Can be incorporated into large worship spaces where controlling reverberation and improving acoustic comfort are important.

Conference Centres

Suitable for conference and event spaces where speech clarity and reverberation control are required alongside a seamless architectural finish.

Premium Retail Interiors

Can be used in high-end retail environments where acoustic treatment needs to blend into the overall architectural design.

Frequently Asked Questions

What is acoustic plaster?

Acoustic plaster is a seamless acoustic wall or ceiling system that combines a sound-absorbing mineral wool core with a site-applied plaster finish. It provides sound absorption while creating a continuous architectural surface.

How does acoustic plaster absorb sound?

The plaster system is installed over a sound-absorbing mineral wool core. Sound energy interacts with the surface and reaches the absorptive mineral wool layer, helping reduce reflected sound and reverberation within the space.

What is the difference between acoustic plaster and conventional plaster?

Conventional plaster is primarily used as an architectural finishing material, while acoustic plaster is part of a complete sound-absorbing system that incorporates an absorptive core such as mineral wool.

What is a seamless acoustic ceiling?

A seamless acoustic ceiling is an acoustic ceiling system designed to create a continuous surface without visible panel joints or a conventional exposed grid. Acoustic plaster systems achieve this appearance through a plaster finish applied over an acoustic substrate.

Can acoustic plaster be used on walls?

Yes. Acoustic wall plaster systems can be installed on suitable wall surfaces as part of an overall acoustic treatment strategy.

Can acoustic plaster follow curved ceilings?

Yes. The system can follow curves, vaults, irregular geometry, and other architectural profiles, making it suitable for projects with complex ceiling and wall forms.

What thicknesses are available?

AcouStick Acoustic Plaster systems are available in 20, 25, 30, 40, and 50 mm applied thicknesses.

What mineral wool is used behind acoustic plaster?

The acoustic core can use rock wool or glass wool, depending on the selected system and project requirements.

Where can acoustic plaster be used?

Acoustic plaster can be used in hotel lobbies, atriums, auditoriums, museums, galleries, showrooms, places of worship, conference centres, and premium retail interiors.

How much does acoustic plaster cost in Saudi Arabia?

The price depends on the system thickness, mineral wool type, area, geometry, installation method, finish, colour, and project requirements. AcouStick provides project-specific pricing based on the required configuration and installation conditions.
