Air Barriers 101: Basic Theory and Design

Research conducted at OakRidge National Laboratories in Oak Ridge, TN, National Research Council Canada, and many other institutions around the world have shown that controlling airflow through the building envelope is more important and effective in reducing heat loss and moisture transport than controlling vapor diffusion.

Research conducted at OakRidge National Laboratories in Oak Ridge, TN, National Research Council Canada, and many other institutions around the world have shown that controlling airflow through the building envelope is more important and effective in reducing heat loss and moisture transport than controlling vapor diffusion. This research has demonstrated that air leakage through the building envelope has the ability to transport exponentially more moisture through the building envelope than occurs through water vapor migration. Controlling air flow has reduced problems such as corrosion, deterioration of wall components and the growth of mold.  Other benefits are improved energy efficiency and indoor air quality.
