Description

BlockFlash is a complete, embeddable flashing solution for managing moisture in exterior single wythe CMU walls.  It uses patented flashing pans to collect moisture in the wall and channel it to the exterior through integrated weep spouts.  Its included drainage mesh provides hundreds of clear pathways for water to flow around mortar droppings inside the block cells so it can be collected by the pans.

Features

  • High-density polypropylene sloped flashing pan with perimeter flanges, integrated weep spout and connector bridge.
  • All drainage mats made of 90% open weave polyester mesh
  • Factory-installed 90% open weave polyester mesh insect guards keep insects out of the block cells
  • Available for 6″, 8″, 10″, and 12″ standard or insulated concrete masonry units
  • Drainage mats for 8″, 10″, and 12″ sizes are 7″ x 16″; drainage mats for 6″ size are 7″ x 14″
  • Snap-off connector bridge allows fast and easy pan installation in reinforced wall systems and at corners
  • Integrated bottom lip on weep spout makes it fast and easy to accurately align flashing pans
  • Drip spouts include a 45 degree drip edge to deflect moisture away from the wall and help prevent water marks and efflorescence
  • Sloped pans with integrated edge flanges catch and funnel water to the weep spouts
