<br /> Rough-ln: After installation of the complete air distribution system but before installation of insulation and
<br /> sheet rock. Allows for access to all duct seams and connections for re-evaluation of seal integrity if standard
<br /> is not met in intitial test.
<br /> Post Construction: At or near final inspection. The home must be complete enough to pressurize the home
<br /> to 25 pa.
<br /> Total Leakage: Aggregation of the entire systems duct leakage in a duct test.
<br /> Leakage to Exterior: Aggregation of all duct system leaks to the exterior of the CFA in a duct test.
<br /> Pascal (pa): Unit of pressure
<br /> CFA: Conditioned floor area in square feet
<br /> CFM25: Cubic feet per minute of air leakage at 25 pascals of pressure
<br /> CFM50: Cubic feet per minute of air leakage at 50 pascals of pressure
<br /> Conditioned Volume: Volume of conditioned space (CFA X ceiling hieght)
<br /> ACH50:• Air changes per hour at 50 pascals of pressure
