To understand how a material would perform in an actual installed environment, seek a product’s third party test data for the ASTM-C423 standard. BASWA Systems have been tested using ASTM-C423 A & E Mounting in order to give the most accurate indication of its performance characteristics in multiple installation conditions. Uniquely, BASWA systems are acoustically consistent in performance, despite differing installation conditions from project to project, due to its simplistic system installation requirements.

In truth, very little is sound "proof." However, excellent sound control can be achieved with the right product. If you want to reduce the noise level in a room, add sound absorption. If you want to reduce the transmission of noise from one room to another, add high sound transmission loss values to your walls, ceilings, and floors. BASWA Phon can add 5-7 points to STC rated wall or ceiling, in conjunction with products specifically developed for managing sound transmission. The STC (Sound Transmission Class) is a single-number rating of an assembly's ability to resist airborne sound transfer. In general, a higher STC rating blocks more noise from transmitting through a partition.
High frequency sound absorption is accomplished by allowing sound wave energy to pass through the micro-porous finished surface of a BASWA System, thereafter dissipating into heat energy in the mineral wool panel. When low frequencies hit a BASWA System, the surface vibrates like a diaphragm. These vibrations are then converted to heat energy as well. BASWA Phon has a noise reduction coefficient rating up to 1.00, unmet by other products. This reduction of mid-range and extreme high or low frequencies allows for clearer sounds in any room, hall, atrium, or auditorium. BASWA Phon absorbs consistently high in all frequencies.

Reverberation is sound resonance, similar to what you might think of as an echo. Reverberation Time (RT) is the time it takes for sound to decay by 60 dB once the source of sound has stopped. Reverberation Time is affected by the size, shape and volume of a space and the amount of reflective surfaces versus the amount of absorptive surfaces within a space. Reverberation has an important impact on speech intelligibility, and can affect safety, learning, or the quality of an everyday conversation.
NRC - Noise Reduction Coefficient Rating (NRC Rating): The average of a material’s sound absorption coefficients at 4 frequencies of 250, 500, 1000, 2000 Hertz. This number is between 0 and 1; zero being perfectly reflective and 1 being completely absorptive. BASWA Systems have NRC Ratings up to 1.00.
CAC - Ceiling Attenuation Class: The performance of a ceiling system as a barrier to airborne sound transmission through a common plenum between adjacent closed spaces.
STC- Sound Transmission Class: Integer rating of how well a building partition reduces the amplitude of airborne sounds. Considered when trying to minimize the transfer of sound through a wall between two adjacent spaces.
IIC- Impact Insulation Class: The ability to block impact sound by measuring the resistance to transmission of impact noise or structure-borne noise (ex. objects dropped on the floor)
Sound absorption refers to the process by which a material takes in sound energy when sound waves are encountered, as opposed to reflecting that sound energy. All materials are either acoustically absorbent or reflective. Hard surfaces, such as glass or concrete, tend to be more reflective, while soft surfaces, like furniture, drapery or carpet, are absorptive. Acoustically absorptive materials are typically rated with an NRC Rating. Learn more about acoustics here.
Any BASWA Finishes that are trowel-applied smoothly are great projection surfaces with high light reflectance. Projects utilizing BASWA Systems for projection include multiple Planetariums, museums, and the New World Symphony Hall in Miami. Contact BASWA to get more information for your application.
BASWA Finishes differ minimally, with the main contrast being the size of marble aggregate. Classic Fine and Fine utilize the finest aggregate and Classic Base, Base, and Frost with a slightly larger aggregate.
Finishes designated with “Classic” are two coat finishes and are ideal for most applications and in areas with high critical lighting. As such a product is hand applied, two-coat systems are best for achieving the smoothest possible finish.

BASWA Phon is an ideal system for existing construction and historical renovations. BASWA Phon can be applied directly to an existing, stable substrate, with the capability of preserving original plaster or encapsulating asbestos. Decorative moulding and hand-painted motifs are possible. Learn more about how BASWA Systems can be applied in Historical Renovations here.
BASWA Phon Systems can be applied to walls and ceilings, and are great for flat, curved, domed, complex-curved or vaulted surfaces.
BASWA Systems are great in high humidity environments. BASWA offers system options for ≤75% or ≤95% relative humidity. BASWA Finishes are not water soluble. Past installations include spas, natatoriums, porte-cochères, and covered outdoor spaces. BASWA Phon tested with no mold growth per ASTM D 3273-16. Learn more here.
BASWA Finish materials are capable of creating infinite custom aesthetics and finishes. Employing creative troweling or spray applying techniques in addition to utilizing the endlessly custom BASWA Colors tint additive or BASWA Shine materials, BASWA systems can be artistically matched to stone or concrete, or a completely unique texture. Learn more here.
BASWA Finishes can be installed over BASWA Hybrid or directly applied to drywall to allow for the fine tuning of sound within a space, absorbing the high end frequency range. This type of application is best for performance spaces with challenging high frequency regulation needs and will not affect the overall dynamism of the performance. Third party acoustical test data for BASWA Hybrid available upon request.
BASWA acoustic does not believe owners and designers should be limited in choices of finish colors. BASWA Systems can be finished to match any color or multiple color gradients, tying the finished surfaces into the overall design aesthetic of the space. In no way does the tint affect the acoustical absorption qualities, as these colors are integrally added to the product before application.
If a mural or decorative accent painting is desired, care must be taken to select a paint that is not likely to bridge pores, such as a water based paint. Acoustical ceilings perform through the porosity of their surface and lose their acoustical absorption when painted with traditional paints.
Contact BASWA acoustic to find out more about color and how you can start planning your new finish.

BASWA Phon Supporting Panels are adhered to the substrate using the plaster based BASWAphon Adhesive. The panels, which are 2’- 8” x 1’- 11”, are heat bonded mineral wool panels with a factory-applied and sanded brown-coat of recycled glass beads. BASWA Panels are available in 3 thicknesses: 26mm, 36mm, and 66mm. The difference between thicknesses is the measurement of the mineral wool layer only. Each panel thickness option absorbs frequencies differently. Learn more about the installation of BASWA Systems here.
BASWA Phon systems are installed over a new or existing, stable, sealed substrate. Ideal substrates include standard drywall with taped joints (no finished coating of the tape or screw heads required), concrete, intact existing plaster, or GFRG forms. Due to the system’s lightweight construction, ceiling substrate system does not typically require additional or unusual support.
HVAC diffusers, fire sprinkler heads and light fixtures are roughed in below gypsum board to finished ceiling height. Voids and penetrations not yet sealed with drywall tape are sealed with adhesive tape. This creates sealed substrates that do not allow air to pass through which would otherwise cause discoloration over time. Learn more about the installation of BASWA Systems here.
BASWA Phon can be applied to curved, domed, vaulted or warped surfaces. In order to make the panels more flexible, the backs are factory-kerfed in one or two directions. For extreme applications, the glass bead crust can be heated. The panel becomes pliable and can be fitted to the curved or domed surface. The panel is then screwed in place until the adhesive is dried. Screws are then removed and screw holes are filled with BASWA Fill, the same material used to factory-coat the panels. This ensures monolithic acoustical absorption without potential telegraphing of mechanical fasteners. Learn more about the installation of BASWA Systems here.
BASWA Phon can be integrated into any design concept and can be installed around light fixtures as well as access panels and speakers. By roughing in these items, the lighting and speakers can be flush with its surface. No pre-installation measurements are needed as all cuts are made onsite to accurately fit each light, speaker, diffuser, access panel, etc.
Concealed speakers can be recessed into a BASWA Panel, meshed, and coated with the chosen finish to create an invisible speaker aesthetic.

Under normal circumstances, BASWA products age evenly and do not require any maintenance. However, surfaces may be damaged by punctures, stains, or water. Similar to any building material, a BASWA surface may accumulate a buildup of dust particles. Acoustical ceilings perform through the porosity of their surface and therefore can not be cleaned with conventional products. BASWA acoustic has developed a range of techniques and products, which allow for removal of staining or repair of surface damages without affecting the acoustical performance.
