A typical urban and suburban environment has numerous sources contributing to the exterior ambient noise. Among these are the environmental sounds from a building’s heating, ventilating, and air-conditioning equipment. How can design professionals help mitigate the distraction caused by HVAC?
Continuous insulation (ci) has been a component of exterior wall assemblies for more than 40 years in North America and even longer in Europe. It has always been the smart way to design wall assemblies from the standpoint of energy conservation and water management. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment.
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. Now, in some respects, the construction industry has come full circle.
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. One such trend is the use of architectural metal wall panels as roofing to create a visually seamless transition between building walls and roof surfaces such as low-slope setbacks in the façade. This can impose unique challenges for the designer and contractor.
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.
