Key principle of air movement: Air moves from warm to cold

1. Vapor-permeable assemblies for all climates – Promotes drying of the wall cavity in either direction.

2. Non-permeable assemblies for high humidity or cold climates – Reduces condensation on cold surfaces.

3. Non-permeable southern assemblies for hot/humid climates – Reduces thermal bridging.

4. Typical UV-resistant assemblies for architectural panels with open joints –Ensures long-term durability.
