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.
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.
The Brick Industry Association (BIA) has named its ‘best in brick design’ projects, bringing together a diverse list of buildings from across North America. Selected by an independent panel of judges, this year’s edition of the Brick in Architecture Awards featured more than 150 entries.
There are two main field testing methods used for water repellency of concrete masonry units (CMUs), for quality assurance before being placed in a wall: droplet and RILEM tube testing. Completed assemblies can also be tested with RILEM tubes or other standard water spray tests such as ASTM E514, Standard Test Method for Water Penetration and Leakage Through Masonry.
