Weather resistive barrier’s (WRB) assembly provides separation between the conditioned space and the exterior.
Weather resistive barries need to control
- Heat
- Air
- Moisture flow
- Rain and rain penetraction
- Vapor
- Light, solar, and other radiation
- Noise and vibration
Types of weather resistive / water resistive barries
- Self-adhered sheet
- Fluid-applied membrane
- Closed cell, medium density spray polyurethane foam
- Factory-bonded membranes to sheathing
- Boardstock, rigid cellular insulation board
- Mechanically attached flexible sheet
