What is an air barrier?

...air barrier as being: 1. Continuous: no gaps, cracks or openings. 2. Impermeable to the leakage of air. 3. Rigid: supported in both directions from wind pressure. 4. Durable: must last the life of the building. 5. Repairable: access for repair if damaged. A sampling of air barrier materials and techniques: ...

How to install an air barrier for reduced air leakage

...air barrier is to stop air leakage through differences in air pressure between inside and out. A wall system should have one vapour barrier, but can have many air barriers. A vapour barrier can act as a very effective air barrier, but an air barrier does not (and should not) always stop vapour from difusing. Understa...
