Reduce your reveration time with stone wool ceiling panels

Now available in a wider range of standard sizes, styles, and formats, Rockfon Sonar® ceiling panels contribute to commercial projects’ creative designs, industry-leading performance, and sustainability goals.

High-performing absorptive ceiling panels of NRC 0.95 can improve the acoustic experience in open-plan offices, classrooms, retail shops, healthcare patient recovery areas, as well as in multifunctional rooms, corridors, meeting rooms, lobbies, and reception areas. In addition to the benefits associated with 0.95 NRC, Rockfon Sonar’s Articulation Class (AC) rating of 190 supports speech privacy, such as for conversations in human resource departments and medical clinics with partial height walls.

High sound absorption helps control the ambient noise levels and prevents excessive reverberance. This increases speech intelligibility, improves concentration and mitigates the ‘Lombard effect,’ where people talk louder and louder to make themselves heard when trying to talk in noisy environments.

Along with high acoustic performance, the panels’ lightly textured white surface delivers high light reflectance (0.85 LR) to maximize daylighting and dimensional stability at up to 100% relative humidity. Contributing to buildings’ environmental goals, Rockfon’s extensive portfolio of stone wool acoustic ceiling solutions has earned UL® Environment’s GREENGUARD Gold Certification for low-emitting products.
