Obvious and Not-So-Obvious Reasons to Love Air Barriers

Air Barriers Energy Use

Course Description

The most obvious thing to love about air barriers is their contribution to energy efficiency: the better we are at separating the inside from the outside, the less energy we require to condition the interior space. But air barriers also make substantial, noticeable contributions to occupant comfort, including improved indoor air quality, acoustic control, and thermal comfort. This short presentation describes the advantages of air tightness, outlines how it is measured, and reviews the most critical design details to achieve the best results.
