Most of these projects have very little urethane foam sprayed in them and are insulated with densepack cellulose in the walls. One of the projects tested out at .56 ACH50, and the others were at .89 ACH50, 1.1 ACH50, etc.. Another key to this is the use of the airtight electrical box and a foam gasket around the flange. First, the question that started this all: clearly the question is based on a confusion between vapor barriers and air barriers. Vapor barriers are intended to control vapor diffusion. Air barriers are intended to control air leakage. Poly can be used as an air barrier, but it provides a vapor barrier when you do it. Article 314 in the National Electrical Code, “Outlet, Device, Pull and Junction Boxes,” includes no mention of airtight box requirements.
