Air Flow Control in Buildings | Building Science Corp

As noted earlier, the secondary planes of air flow resistance fulfill several functions, either on their own or in conjunction with the other planes of air flow resistance. These secondary barriers not only add marginally to the overall airflow resistance of the assembly, they provide a level of redundancy if the primary air barrier is designed, built, or performs imperfectly.
