BLOK-FLASH® embeddable flashing device

 

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.
