Phoenix, Ariz., is among the nation’s fastest growing cities. According to the U.S. Census Bureau, the city’s population has grown about 3 percent (now at more than 1.5 million) since 2000. The Bureau also reports that Phoenix, which a century ago was not even among the 100 most populous cities in the country, has passed Philadelphia in total population to become the fifth biggest American city.
As masonry wall design continues to evolve into the 21st century, terms like “air and vapor barriers,” “steel stud assemblies,” “rigid insulation versus batt insulation,” “ventilation with weeps and vents,” “clear air space,” and “oversize masonry units” are all employed to describe today’s masonry wall. Each one of these items can have a direct impact on wall reinforcing and anchoring systems. Add to that list things like “green” and “sustainable,” and, well, you get the idea. Masonry has gone through quite a transformation over the last handful of years.
