BASWA Natural is a natural, hemp and flax fiber based seamless acoustical plaster system applied directly to ceilings and walls to manage room acoustics. BASWA Natural achieves 51% less CO₂ per m².
With a flexible panel design, BASWA Natural can be used on domes, groin vaults, and complex curves as well at flat ceilings and walls. The system captures sound energy as it passes through the microporous, recycled marble finish and is absorbed into the randomly-spun natural fiber layer.
Panel thickness, finish texture, and color are all selected to meet the acoustic and visual requirements of a specific space. The sections below will guide you through these variables.
BASWA Natural takes the established standards of seamless design versatility and acoustical performance of BASWA Phon and reimagines it with a natural fiber system panel. Ideal for residential and studio applications. See BASWA case studies >
BASWA Natural follows a stable substrate, like standard drywall, concrete, or existing plaster. With a versatile finish options, BASWA Natural is the ideal acoustic system for spaces with flat or complex forms that demand sustainability-forward acoustic solutions made with natural materials.
BASWA Natural panels are made exclusively from hemp and flax fibers sustainably cultivated by regional farmers who adhere to strict environmental standards. Not only does hemp store massive amounts of CO2, but it is also quickly renewable and incredibly efficient. In addition to its carbon sequestration capabilities, it is naturally resistant to pests and can be grown without the use of pesticides. Hemp is durable, long-lasting, and mold and fire-resistant.
BASWA system finishes are produced from marble aggregate, a byproduct of stone extraction, and contain 93-95% recycled content. Free of LBC Red List materials.

Each system thickness has its own acoustical performance profile. For precise performance data, access the BASWA Downloads.

Best for mid-to-high frequency absorption, or in spaces with ceiling or wall depth constraints.

A mid-range option that with absorption into lower mid frequencies. Most common selection.
Special order thicknesses may be available upon request. Requires minimum order qualitites.
BASWA's recycled marble-aggregate finishes are trowel-applied for smooth surfaces or spray-applied for texturized finishes, available in natural white stone or custom color for a highly customizable design .

BASWA Natural panels are adhered directly onto stable substrates using a gypsum-based adhesive, and can follow complex curves and geometries. The beveled edges of the factory-coated panels form v-grooves which are filled with the same materials as the recycled glass bead panel pre-coat. This forms an acoustically monolithic surface free of mechanical fasteners, perforations, or seams that typically become visible over time.
Recycled marble aggregate finishes are then trowel-applied in one or two coats, in alignment with the lighting design and geometric complexity.
Installation typically takes 4-5 days. All BASWA systems are installed by local BASWA Certified Installers that are located throughout the world.

BASWA systems easily integrate with trimless fixures and diffusors, access panels, and other fixtures. During substrate preparation, all penetrations are roughed-in to accomodate the thickness of the selected system.

Many BASWA systems can be installed in spaces subject to high humidity such as covered outdoor spaces, pools and natatoriums, kitchen, gyms and spas.
In theses environments, it is important to ensure the dew point is not located on or within the BASWA system.
If you are interested in such an application, BASWA acoustic can help determine which system panel is most appropriate for your space to ensure a long lifespan.

BASWA systems are often used in ceiling and walls with concealed speakers behind the finish in projects like home theaters, lobbies and permanent museum exhibits.
Speaker boxes are framed into the substrate and panels are fitted around them. After a mesh is installed to cover the speaker box, BASWA finishes coat the surface uniformly.
The result is a seamless finish with high-performance sound absorption that invisibly accommodates clear, crisp amplified sound.

BASWA systems have been installed all over the world since 1991, delivering acoustical comfort to museums, universities, private clubs, and homes. Our portfolio can offer inspiration and case studies that confidence that demonstrate a lasting value.
