Learning to Breathe Again (CM18-2-21)
Course Description:
Over the past few decades we have added more and more layers to our walls in order to save energy but we have in the process sacrificed some ability to tolerate moisture intrusion. Recent research has shown the benefits of drained and vented claddings and adaptive materials like smart vapor retarders have created new options for managing the moisture flow and moisture storage of the assembly as a whole. In order to take advantage of these options, we must understand the inter-relationships of heat, air, and moisture flow and so we will review these basic forces and identify strategies for preventing wetting while promoting drying both towards the interior and the exterior.
Learning Objectives:
- Discuss how the building code addresses heat, air, and moisture flow and how recent changes to the code could potentially reduce building durability
- Describe some of the properties of building materials that play an important role in moisture management
- Explain the concept of safe moisture storage
- Discuss how insulation assemblies can help prevent wetting while promoting drying on the interior side of the wall while drained and vented claddings to the same on the exterior
