Masonry materials and wall systems, with their inherent thermal mass characteristics, provide designers with many options to achieve energy-efficient designs. This article illustrates examples of wall configurations that exceed national building code requirements and high-performance standards, taking into account factors like increased R-values for non-mass opaque walls (prescriptive design), continuous insulation, requirements for R-value reductions caused by thermal bridging, mandatory continuous air barriers, and options for building energy design.

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, …

When properly applied, tests can yield valuable insight into the installed performance of systems, aid investigators in determining the cause of a failure, or help to determine if a product is performing to its intended level. However, when improperly applied, many tests and standards can produce misleading results, improper conclusions, and lead to unnecessary repairs or remediation efforts. Within this context, the article takes an in-depth look at roofing assemblies, along with glazing, masonry, and air barrier assemblies.
