Improved Building Envelope Air Barrier Systems

Improved Air Barrier Systems

According to the Air Barrier Association of America, air leakage from the deterioration of the building envelope can result in up to 40% added cost for heating and up to 15% for cooling. The US Department of Energy has published findings that 10%+ of all US energy used is attributed to the condition of the building envelope.

Buildings may appear to be tightly constructed, but air leakage gets magnified due to positive or negative differential pressures between the outside and inside conditioned space. Air leakage can be the result of poor initial construction, the deterioration of aging materials, or the expansion and contraction of surfaces over time.

Air Leakage Diagram

Air leakage can result in:

  • Unnecessary heat loss in the winter and heat gain in the summer
  • Improper operation of mechanical ventilation systems
  • Poor indoor temperature and humidity control
  • Degraded indoor air quality
  • Condensation, moisture, mildew and mold in hidden roof & wall cavities
  • Deterioration of building materials at leakage points
