During the medieval period, complex Gothic structures were built from drawings that communicated a designer’s overall vision without detailing specific means of construction. Master craftsmen translated designs into buildable structures using simple tools available at the time.
Some modern architectural designs use newer materials and metal panel assemblies for roofing applications, many of which are not intended to be used as roofing and, therefore, may not be well-suited for it.
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.
The April 2013 issue of The Construction Specifier included a technical feature by J.W. Mollohan, CSI, CCPR, CEP, LEED GA, entitled, “Exterior Wall Assemblies: Are You Getting What You Specified?”
To ensure optimal fire protection, building codes require interior wall assemblies to be evaluated by industry standards to determine their fire performance. This article gives examples of fire-rated wall assemblies and passive firestop systems, describing the testing they must go through to achieve their fire ratings.
