In the August 2013 issue of The Construction Specifier, we included a Horizons column—“Introducing ‘Breathability’ to Curtain Walls—by Raymond Ting, PhD, PE.

As a complement to our more straight-ahead technical features, Horizons examines still-emerging technologies and new ways of assembling buildings. In this particular case, Ting dealt with the issue of glazed assemblies and their impact on both energy efficiency and indoor air quality (IAQ). He acknowledged …
