4.1. Identifying Common Issues

Be proactive in identifying potential air barrier issues. Some common problems to watch for include:

  • Air leakage: Drafts or unexplained temperature fluctuations may indicate air leakage in the air barrier system.
  • Condensation or moisture issues: Excess moisture, mold, or mildew may be a sign that the air barrier is not effectively controlling moisture movement.
  • Peeling or damaged materials: Inspect the air barrier for visible damage, such as peeling, cracking, or punctures, which may compromise its performance.
  • Gaps or misalignments: Check for gaps or misalignments in the air barrier material or at joints and penetrations, which can lead to air leakage.
