St. Louis International Airport recently remodeled the ceilings of the passenger check-in area in all four terminals. International Cellulose’s SonaKrete Acoustical Finish was chosen for several reasons. First and foremost is SonaKrete’s excellent noise absorption ability, which dramatically reduces reverberation or echo time.
SonaKrete’s Arctic White color provides a light reflectivity of 81%, which brightened the spaces considerably. Because SonaKrete can conform to just about any shaped surface, its application would not change Minoru Yamasaki’s domed design. SonaKrete is a spray-applied, hand-trowelled, premium finish that eliminates the popcorn look of other sprayed acoustic products.
SonaKrete may also qualify for multiple LEED Credits. SonaKrete provides an NRC of .65 at only ½” application. This achieves a lower installed cost than traditional 1” thick, sprayed acoustic plaster systems. The two standard colors of SonaKrete are White and Arctic White; however, virtually any custom color is available.
ICC’s spray-applied thermal and acoustical materials are readily available for shipment to our network of licensed installers. Please contact us for details on how we can help your project be the best it can be! https://www.spray-on.com/
