Disclosed herein are methods and apparatuses for an improved air barrier system for use in residential or commercial buildings. An individual practicing the method, or an apparatus configured to practice the concepts disclosed herein, would insert an insulated envelope between joists located in a joist bay of a building, where the insulated envelope has a flap and the insulated envelope envelopes insulation. The user places the flap over insulation previously distributed on a floor of the joist bay, and applies an air impermeable coating over at least a portion of the flap of the insulation. By inserting the insulated envelope and applying an air impermeable coating over a flap and pre-existing insulation, the ability for attic vents to wind-wash conditioned air out of fiberous insulation is diminished. |
