To limit the probability that the performance of sealant materials used in air barrier systems will fall significantly below expectations with regard to the air permeance and resistance to deterioration,
which could lead to a loss of airtightness, which could lead to excessive air infiltration and exfiltration through the building envelope, which could lead to excessive heat loss or gain, drafts or high indoor relative humidity, which could lead to the excessive use of energy for heating and cooling, which could lead to an unacceptable effect on the environment.
