In the North Platte Auditorium, Black K-13 was used in conjunction with a drywall cloud system. K-13 black was also chosen to hide the ceiling and rigging work and to contrast with the ceiling panels, creating an attractive grid effect. Gymnasiums are the most typical SonaSpray ‘fc’ application for schools. The hard, acoustically reflective surfaces create very high reverberation times. Thus making speech and announcements unintelligable. SonaSpray ‘fc’ in Arctic White was applied to the roof deck to reduce the reverberation time. Arctic White was chosen for its high light reflectivity and clean appearance. Additionally, the resillient fibers of SonaSpray ‘fc’ resist impact damage.

K-13 and SonaSpray ‘fc’ are also ideal for use in pool areas and classrooms. Other applications include churches, office buildings, retail stores, bars and restaurants, parking garages, and airports.
