For areas such as indoor pools and ice arenas, K-13 aids in condensation control. The proper combination of K-13 and ventilation prevents condensation on metal, concrete and other surfaces. K-13 actually reduces ventilation requirements, saving in both the ventilation equipment investment and operating cost.
Acoustical Performance
The resilient fibers of K-13 absorb sound energy instead of reflecting it, reducing reverberation time and making speech and music more intelligible. Excessive noise is reduced with the application of K-13 while greatly improving ambient sound quality in a wide variety of building projects including auditoriums, sports facilities, detention facilities, television and sound studios, convention centers and parking garages.
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 unequaled NRC of.65. At its maximum recommended thickness of 1″, the NRC is .90.
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 sheet rock, 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.
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.
