Older construction was built with solid brick walls, which meant water infiltration was seldom. Today’s buildings are built with through wall flashing, which is used to divert moisture that enters a cavity wall system. Through wall flashing is typically comprised of:

  • Self-adhering rubberized asphalt
  • Copper
  • Metal
  • EPDM rubber
  • PVS plastic
