Waterproofing for CMUs: What About Stucco?

In the July 2014 issue of The Construction Specifier, we published the article, “Durable Waterproofing for Concrete Masonry Walls: Redundancy Required,” by Robert M. Chamra, EIT and Beth Anne Feero. A month later, we received the following e-mail from G. Michael Starks, president of the Florida Lath & Plaster Bureau (FLAPB):

I thought this article offers sage advice should your plans call for struck and painted concrete masonry unit (CMU) walls. Unfortunately, …

Using Temperature to Control Condensation in Cold Climates

Initially, water vapor diffusion was seen as the likely culprit for condensation problems; designers and consultants spent hours running and analyzing wall assemblies using the dewpoint method. With such analyses came the concept the wall system should be tuned for maximum condensation resistance by altering or selecting the appropriate permeability of the wall components. However, to create a truly robust wall system with the greatest condensation resistance and drying potential, designers need to look at altering the temperature profile of the wall assembly by moving insulation as far as possible to the exterior of the wall.

Metal Wall Panels on the Roof: How to achieve durability and reliability using sheet metal

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.

Minimizing Risks with Solar Roofs

Commercial low-slope rooftops are an attractive platform for the installation of solar photovoltaic (PV) electricity-producing systems. Nevertheless, a roof’s function is, first and foremost, to protect the building’s contents and people from the elements. In this regard, design professionals need to anticipate the potential risks associated with the installation of roof-mounted PV arrays. This sort of due diligence is particularly important when installing PV systems on existing warranted roofs.
