Requirement

Result

Five 1-m2 specimens tested and measured for air permeance at a minimum of six air pressure differentials between 0 and 250 Pa

Air leakage rate at 75 Pa (based on linear regression of 30 data points) ≤ 0.02 L/(s·m2)

0.018 L/(s·m2)

Water vapour permeance at 25-mm (1-in.) thickness

Report value

83.9 ng/(Pa∙s∙m2)
