Summary
Through-wall flashing is a water shedding device to divert water from the cavity to the exterior of the building. To provide durable buildings, we need an informed position on the design attributes of flashing:
- Imperviousness to water
- Resistance to damage during construction—puncture, tear, sunlight, and fire Prevention of discoloration to exterior cladding
- Compatibility with adjoining adhesives and sealants (and everything else it contacts)
- Matching durability of flashing to anticipated life of the building
Topics
- Understand the purpose of through-wall flashing
- Performance criteria used to specify through-wall flashing
- Understand the attributes of commonly used flashing materials
- Understand compatibility issues between cavity wall components
