Posted on June 20th, 2016 by Heather West

ROCKFON_ON_MitonOffice-Open218-web.jpgHelping optimize acoustics for today's commercial interiors, the ROCKFON Group offers an extensive portfolio of sound-absorbing, acoustic stone wool ceiling systems. These include baffles, islands and ceiling panels that can achieve Noise Reduction Coefficients (NRC) as high as 0.95. Sound-absorbing ROCKFON ceiling products shorten reverberation time, improve speech intelligibility, decrease noise levels and promote privacy.

"ROCKFON Optimized Acoustics™ provides a simple, straightforward approach to meet current acoustic standards, guidelines and criteria, while keeping on budget. With ROCKFON ceilings you can optimize the ideal acoustic environment without compromising style or performance," says Gary Madaras, PhD, ASA, INCE, Assoc. AIA, acoustics specialist at the ROCKFON Group.

Madaras explains, "NRC indicates the amount of noise absorbed by a ceiling material. Typically, the higher the NRC the better. Ceilings lower than NRC 0.70 often require additional absorption on the walls. Look to your ceiling panels to meet the high absorption requirements you need and to your walls for blocking, when it's needed."

ROCKFON Alaska®, with an NRC of 0.90, provides sound absorption for open plan offices, classrooms, retail and reception areas.
