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. |
