Air barrier systems provide several advantages for building projects, including increased interior comfort, durability and energy efficiency. With these attributes, they are suitable for a variety of applications in various climates.
Air barriers have the potential to reduce air leakage to acceptable levels for less than $1.50/square foot of gross building area, and are often specified for buildings. Air barriers are typically regulated through energy codes, which recognize the importance of airtight buildings and energy efficiency. As of early 2006, several states have developed existing and pending legislation on air barriers, as well as compliance criteria.
