When we look at the modern building environment, one of the hottest topics on many people’s minds are weather barriers and moisture control. Air and moisture management are concerns not only to the design/development side of the industry, they are also major concerns to the construction team who are the front line in ensuring that the proper system is used and installed correctly.
We look to these systems to control not only the penetration of liquid water but also to control the migration of water vapor. When these systems fail, and moisture infiltrates a structure, a cascading host of problems can result, wood begins to rot, mold begins to grow, steel corrodes, and insulating R-values decline, the list of issues can seem to be endless. Not to mention that air migration through wall assemblies decreases the overall energy efficiency of the building.
