SonaSpray "fc" is a spray applied acoustical texture designed for a wide range of project types. SonaSpray "fc" provides an attractive, high performance solution to acoustical and lighting design objectives in both new construction and renovation projects. Typical installations include: schools, churches, passenger terminals, libraries, cafeterias, offices, hotels and condominiums.

SonaSpray "fc" is available in standard colors White, Artic White, and Black. Specially matched colors are also available as a design option.

Acoustic TreatmentAcoustical Performance

SonaSpray "fc", as tested by a NVLAP accredited acoustical laboratory per ASTM C-423, provides an exceptionally high noise reduction coefficient (NRC). A typical installation of 1/2" thick on solid backing, has an unequalled NRC of.65. At its maximum recommended thickness of 1", the NRC is .90.

SonaSpray outperforms all other acoustic remediation products on the market today. Noise reductions of 65% to 90% are common results achieved from using this product. SonaSpray is also Class I fire rated, meeting all local and state code requirements.

Substrate Compatibility

SonaSpray "fc" is spray applied and will conform to any surface configuration such as barrel vaults, concrete "T", corrugated decks, pan construction and other complex surfaces. The high performance adhesive will bond to virtually all common construction materials including sheetrock, plaster, wood, metal and concrete. Some surfaces (such as water stained ceilings, wood and oxidized metal) will require sealing to prevent migratory staining of the SonaSpray "fc".

Durability and Maintenance

The adhesive used to apply SonaSpray "fc" provides a strong, durable and resilient bond. This unique combination of properties provides remarkable durability. SonaSpray "fc" will resist impact and abrasion without cracking or spalling, typical to any cementitious or plaster based materials. In areas where even high abrasion resistance may be desirable, SonaSpray "fc" Dura-K may be specified. This provides even greater bond and compressive strength without reducing the acoustical performance. SonaSpray "fc" can be painted with water based latex or acrylic paint if desired, without appreciably reducing the NRC value.

Green Acoustic TreatmentClean Manufacturing

SonaSpray "fc" is processed in a clean, efficient, electrically-driven mill that requires relatively little amounts of energy.

  • Takes less energy to make than any other insulation
  • Cellulose has the highest level of recycled content in the insulation industry - up to 85%. Cellulose insulation is made with recycled paper, paper that might otherwise end up in a landfill.
  • Reduces the amount of energy needed to heat or cool a building
  • Fire resistant
  • Helps prevent greenhouse gasses
  • regionally produced, using local recycling programs and independent recyclers, and servicing communities close to home
