There are, of course, many more reasons to choose acoustic ceilings, but these are the most important aspects to consider.
Acoustic - Sound Absorption Coefficient (NRC) - Sound absorption is a primary design criterion and key to more effective spaces for living, working, and relaxing.
Acoustic - Ceiling Attenuation Class (CAC) ¬- Attenuation is an especially significant measure in providing acoustic privacy between adjacent areas, where sound can penetrate plenum spaces and carry to other rooms
Acoustic - Articulation Class (AC) - Articulation rates a ceiling's suitability for achieving normal privacy in open spaces by absorbing noise reflected at an angle off the ceiling into adjacent areas.
Fire Resistance - Local building codes require fire-safe construction for many building applications.
Humidity Resistance - Ceilings are designed to prevent sagging as a result of exposure to high relative humidity (moisture).
Light reflectance - Growing awareness of new, energy-saving lighting often overlooks the integral role of the ceiling. A high light-reflectance ceiling makes lighting systems - especially indirect lighting - more effective, while further reducing energy costs and consumption.
