BLOK-FLASH® is an embeddable flashing device for exterior single wythe C.M.U. wall systems. It collects moisture that infiltrates the wall and flows down the vertical cores and diverts it to the exterior. BLOK-FLASH® is useful at all flashing/weep hole locations including base of wall, above door and window openings, above bond beams, in parapet walls, basements and any other locations where flashing is necessary.

Benefits:
· Useful in all 8", 10", and 12" exterior block wall applications.
· Maintains greater bond than through-wall membrane flashing.
· Eliminates the need for using multiple sizes of architectural C.M.U., reducing set up charges related to producing special sizes.
· Simple installation in reinforced wall systems.
· Reduces thermal break, helping to maintain the walls R-value insulation integrity.
· Saves more than half of the labor and material costs associated with using membrane flashing in a multi-wythe course.
· 45 degree drip edge to deflect moisture away from the wall system.
· Concaved weep spout for ease of tooling.
· Eliminates unsightly head joint weeping devices.
· Light weight and compact shape for convenient shipping, handling and storage.
