The purpose of an air barrier is to limit uncontrolled air leakage into and out of the building\u2019s envelope. A building\u2019s envelope is defined as roof, wall, and floor area that encloses a heated or cooled area. Uncontrolled leakage will result in increased energy usage due to the heat or cooling lost.","thumbnail_url":"https:\/\/insulation.org\/io\/wp-content\/uploads\/sites\/3\/2016\/10\/IO160204_04-1024x535.jpg"}
