The growing awareness of energy efficiency, green building, high performance buildings, and uncontrolled airflow (infiltration or exfiltration) through the building enclosure has led to many performance based requirements for the air barrier system.
Consultants and testing agencies are promoting air barrier performance testing and diagnostic services to building owners and marketing themselves as firms who ensure a 100% success rate is achieved when testing for air tightness when building owners procure their services. When consultants are hired they not only perform ASTM testing on the applied materials but also perform field observations during construction identifying typical compliant and non-compliant construction methods.
