Acoustical plaster for monolithic ceilings and walls. BASWA acoustic systems have been reducing reverberation to promote wellbeing since 1991.
Specified by architects and acoustical consultants across a broad range of commercial, institutional, and residential project types, BASWA systems deliver independently verified NRC ratings up to 1.00 while maintaining monolithic surfaces that disappear into the architecture of a space.
By reducing reverberation, these acoustical finish systems improve speech intelligibility, safety, health, learning, and overall quality of life.
With an ecosystem of supporting panel options and versatile finishes, ideal solutions can be customized that follow flat ceilings, curved vaults, domes, or complex geometries in smooth or textured finishes.

BASWA acoustic is committed to sustainability, from manufacturing to finished product to support long-term ecological balance.

Integrating acoustics into architecture fosters occupant health and wellbeing by creating acoustically comfortable environments that improve on intentional human interactions and productivity.

BASWA acoustical plaster systems reduce reverberation time, providing a tranquil environment to focus on family life, learning, and overall health.

BASWA acoustical plaster absorbs airborne sound energy as it travels through the microporous, recycled marble aggregate finish and is trapped within the supporting panel layer. Sound energy that would otherwise reflect and reverberate off the room's hard surfaces gets converted invisibly into heat energy. The result is a reduction in reverberation time across a broad frequency range, which improves speech intelligibility and reduces acoustic fatigue.
BASWA system performance is deeper than high NRC and CAC Ratings, with high recycled material content, Class A fire ratings, VOC-free materials, high L-value light reflectance, and excellent performance in high humidity environments.
Acoustical plaster finishes allow the necessary acoustic performance to be built into the architecture of a space rather than layered onto the ceiling or walls. With system options that adhere to stable substrates without mechanical fasteners, like drywall or plaster, or that mount directly to grid, each system delivers the seamless, gridless design BASWA is known for.
Design natural white stone finishes or stunning custom textures that replicate other materials. BASWA systems are made to last.

Design a seamless acoustic ceiling or acoustic walls that follow flat, curved, domed, or vaulted geometry without be limited in texture or color options.
Combine design versatility and high performance acoustics with finishes that look like they're doing nothing at all.


BASWA provides acoustic performance consistency, backed by third-party testing. BASWA acoustical plaster systems for ceilings and walls are designed to integrate into any room geometry.
BASWA systems are delivered by an expanding global network of trained, certified local installers, who are supported by BASWA's reliable technical team.
