Stone wool’s various attributes are making the material attractive for use in suspended ceilings in educational, office, and healthcare projects. This article touches on such assemblies’ acoustics, air quality and light reflection impacts, along with information about fire performance, humidity, and dimensional stability. Design professionals must also understand the aesthetic possibilities, including flexibility with edges, sizes, colors, surfaces, shapes, and textures.

Improving Floor/Ceiling Sound Control in Multifamily Projects: Sound Testing Practices

The sound transmission class (STC) and impact insulation class (IIC) are ASTM-derived single number ratings that try to quantify how much sound a stopped by partition being tested. Laboratory testing involves an ideal setting for the floor/ceiling assembly—it is isolated from the walls, and there are no penetrations for HVAC, plumbing lines, sprinklers, can lights, or electrical boxes. In the field (i.e. F-STC and F-IIC), the floor/ceiling assembly often sits on load-bearing walls, is connected to the structure, and contains many ceiling and floor penetrations for the items just mentioned. Consequently, the code allows for a lower rating for field scores over those in the lab.
