Technical Resources

By absorbing echoes and reflected sound BASWA Systems make conversation clearer, even in harsh situations, by reducing reverberation time.

Specifying a seamless acoustical plaster system requires more than NRC ratings. BASWA systems are independently tested to the full set of standards commercial and institutional projects demand — sound absorption (ASTM C423), fire safety (ASTM E84 Class A), mold resistance (ASTM D3273), VOC emissions (CA Section 01350), and light reflectance (ASTM E1477). All tests are performed by certified third-party laboratories and simulate real installed field conditions. Data is available across all BASWA systems, panel thicknesses, and finish types and certified reports are available upon request..

Energy & Atmosphere (EA)

Enhanced Energy Efficiency
1-12 points

INTENT

To design buildings that minimize energy use to reduce the environmental damage caused by resource extraction, air pollution, and greenhouse gas emissions and to facilitate the transition to a clean energy future.

CONTRIBUTION

BASWA system panels offer a range of high R-values relating to the total panel thickness. BASWA finishes are made with recycled marble sand and are cool to the touch. Marble has a natural ability to maintain a cool temperature due to its thermal properties, and quickly absorbs heat and then releases it slowly, creating a cooling effect.

Enhanced Refrigerant Management
1-2 points

INTENT

To eliminate ozone depletion and global warming potential, and support early compliance with the Montreal Protocol, including the Kigali Amendment, while minimizing direct contributions to climate change.

CONTRIBUTION

BASWA Cool is a draft-free, noise-free heating and cooling system with excellent sound absorption with embedded, large-scale water-transporting capillary system providing consistent thermal control at a fraction of the energy typically used in a forced air system, and without the negative effects on the ozone typical with air conditioning systems.

To reduce concentrations of chemical contaminants that can damage air quality and the environment. To protect human health and the comfort of installers and building occupants.

CONTRIBUTION

BASWA systems and system components have been tested for compliance with CA Dept. of Public Health CDPH Standard Method Vers 1.2, 2017. Detailed test data available with results of VOC and TVOC ranges.

Building Product Selection & Procurement
1-10 points

INTENT

To encourage the use of products and materials that have sustainability information available and that have environmentally, economically, and socially preferable impacts in alignment with industry momentum. To reward project teams for selecting products from manufacturers who have disclosed sustainability information about their products and optimized their products across multiple criteria areas.

CONTRIBUTION

BASWA utilizes natural plant fibers, recycled glass, post-industrial recycled marble sand, organic binders, and minimal synthetic materials to produce the most sustainable systems available.

Each BASWA system offers unique sustainable solutions. BASWA Phon, BASWA DTG, and BASWA Basic panels are made with recycled glass, reducing landfill waste and the demand for new raw materials. BASWA Natural panels are made exclusively from hemp and flax fibers sustainably cultivated by regional farmers who adhere to strict environmental standards. BASWA finishes are made of post-industrial recycled marble sand that helps form a micro-porous surface that sound can pass through to be absorbed within the system panel.

Drawing on 100% renewable and locally generated electricity from hydropower in the panel production process requires less energy and emits less greenhouse gas. Using only water instead of solvents in our products helps keep harmful VOCs out of the atmosphere.

Construction & Demolition Waste Management
1-4 points

INTENT

To reduce construction and demolition waste disposed of in landfills and incineration facilities and pollution to the environment. To reduce the environmental impacts and embodied carbon of manufacturing new materials and products. To delay the need for new landfill facilities that are often located in frontline communities. To create green jobs and materials markets for building construction services.

CONTRIBUTION

Typical installation results in less than 3% of panels discarded.  Panel scraps may be acceptable in mixed-glass recycling facilities.  Plastic buckets containing wet materials are recyclable or reusable.  Unused panels and bucket materials can be saved for future projects.

Select products are available in cardboard packaging of our products in cardboard boxes in lieu of plastic buckets, which reduces plastic waste and increases materials per pallet by 50%, and reduces the delivery weight by more than 50%.

Indoor Evironmental Quality (EQ)

Enhanced Air Quality

BASWA systems and system components have been tested for compliance with CA Dept. of Public Health CDPH Standard Method Vers 1.2, 2017. Detailed test data available with results of VOC and TVOC ranges.

Occupant Experience
1-7 points

INTENT

To move beyond neutral or sufficient spaces toward human-centered design that supports customization, enjoyment, and emotional connections between people and the building, thus increasing the likelihood of consistent satisfaction and ongoing stewardship.

CONTRIBUTION

BASWA systems interact with many senses. Sound and reverberation allow us to construct our perception of space and to develop an aural connection to others and place.

BASWA systems can be coupled to provide flexible sound absorption between zones while maintaining seamless aesthetics. BASWA systems offer high-performance, with performance values specific to each system and finish, and have been tested by standard installation conditions, A-mount and E-mount per ASTM C423 as well as CAC and STC testing.

BASWA systems can be installed in covered, outdoor areas to mitigate sound transference to indoor spaces.

BASWA finishes are made with recycled marble sand, which offers many benefits in addition to durability and natural aesthetic. Marble has a natural ability to maintain a cool temperature due to its thermal properties, and quickly absorbs heat and then releases it slowly, creating a cooling effect. Additionally, BASWA system panels offer a range of high R-values relating to the total panel thickness.

BASWA finishes also boast a high light reflectance L value of 91.03 per ASTM E 1477-98.

Accessibility and Inclusion
1-2 points

INTENT

To support the diverse needs of occupants and increase widespread usability of the building to foster an individual and collective sense of belonging.

CONTRIBUTION

The connection between improved acoustics and humans underlines the need for access to wellbeing in all spaces and knowledge on the impact of acoustics on everyday health.

BASWA systems interact with many senses. Sound and reverberation allow us to construct perception of space and determine aural connection to others and places. Aural impression is key to delivering acoustic comfort and calm, and can influence one's comprehension of spatial experience.

BASWA systems can be coupled to provide flexible sound absorption between zones while maintaining seamless aesthetics. BASWA systems offer high-performance, specific to each selected system and finish and have been tested by varying installation conditions, A-mount and E-mount per ASTM C423.

Surface stains are removed by applying BASWA Surface Cleaner, sold by BASWA acoustic. The two part system, solvent and booster, is mixed according to manufacturer’s guidelines and is applied to the affected area. Once applied, BASWA Surface Cleaner has oxidation properties that dissolve organic compounds as well as an anti-bacterial effect that will eliminate any present odors.

Deep Stains & Water Damage

Stains that have penetrated the surface and cannot be removed by the previous actions are removed as follows: Apply a 10% solution of hydrogen peroxide to the imbedded stain. This action “bubbles” the stain to the surface where it can be removed by gently patting the surface with a clean soft white towel. This process can only be used on white finished surfaces.
