Bulk Water Infiltration Mechanisms Approaches to Wall Systems for Moisture Management • Barrier Walls • Drainable Walls • Rain Screen Walls Gravity Capillary Rain Action Driven Pressure Differential Rain is the Main Source of Water for Above Grade Envelope Barrier Wall •Surfaces are face sealed •Have no path for drainage Drainable Walls •Walls are not face sealed •Have secondary barriers to reduce water penetration •Rain screens provides air space for drainage and a capillary break
Rain Screens • Have an air space for drainage and drying How Wall Assemblies Get Wet •Bulk water intrusion •Air current induced moisture vapor movement •Vapor migration by diffusion Managing Water & Moisture • Job 1 keep out the water • Job 2 Eliminate air in/exfiltration • Job 3 Design so the building can dry Water moves as a liquid and a vapor • Leaks in the building enclosure • Moisture vapor piggy-backs on air movement
