Our ceiling panels are especially designed to provide acoustic ceiling solutions that are beautiful while creating healthy, comfortable spaces.
Our Chicago Metallic acoustical grid systems offer a wide range of high performance suspenion system solutions. Reliable and easy to install, they pair well with our complete assortment of ceiling panels.
Rockfon metal ceiling tiles, go beyond standard 2x2 aluminum panels, with a broad range of baffles, curved, linear, open cell, perimeter, plank, and security products suitable for decorative interiors, exterior soffits and high security applications.
Acoustic absorption is part of optimizing acoustics in interiors using acoustic ceiling tiles with high NRC ratings to reduce reverberation time, noise and sound pressure level and to improve speech intelligibility, comfort and privacy.
Sound insulation of ceilings is measured using Ceiling Attenuation Class (CAC). Ceilings should be used for sound absorption and not for blocking sound between rooms. High-insulating wall products, as measured by Sound Transmission Class (STC), should be used to for blocking noise at an STC 45 or higher.
Background white noise, such as the ambient sounds generated by HVAC systems, computers and outside traffic, should be considered as part of the building design. Sound masking systems may be needed to comply with acoustic standards’ noise level requirements.
