Generated explanation

Two cross-sectional drawings show potential air leakage locations between occupied rooms and an insulated attic beneath a sloping roof. The upper drawing highlights the wall/ceiling intersection, the opening around a metal chimney, and an attic access hatch. The lower drawing highlights a plumbing stack penetration, exhaust fans or ducts, partition tops, and a recessed pot light. Dashed outlines identify vulnerable areas, and bold arrows below the exhaust opening indicate upward air movement. Insulation is shown along the attic floor and in the exterior wall, with localized interruptions at penetrations and openings.
