How Air Sealing Can Improve Comfort and Energy Efficiency
Traditional insulation slows heat flow, but many materials do not stop air from moving through gaps. Air can travel around insulation through penetrations, framing transitions, access openings, and incomplete coverage. This movement can carry heat and moisture, reducing the performance of an otherwise well-insulated assembly. Where leakage commonly occurs Common pathways include attic hatches, plumbing and wiring penetrations, rim joists, wall-to-floor transitions, recess
