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.
The article offers an in-depth look at design considerations for fire resistance when building with wood products. It also looks at wood engineering mechanics and design procedures that comply with the International Building Code (IBC), recognizing fire resistance demonstrated by structural wood beams and columns in actual fires.
In the May 2014 issue of The Construction Specifier, we published the article, “Passive Fire Protection and Interior Wall Assemblies,”by Gregg Stahl. Soon after, a reader contacted us regarding what he considered inaccuracies. We reached out to the author and, in the interest of continuing the discourse about this important topic, excerpts from both sides are included below.
For testing certain wall assemblies, the 2012 International Building Code (IBC) requires National Fire Protection Association (NFPA) 285, Standard Fire Test Method for Evaluation of Fire Propagation Characteristics of Exterior Non-load-bearing Wall Assemblies Containing Combustible Components.
