Abstract

Concrete masonry units, CMU, windows and doors are flashed by applying a side flashing to the top and sides of the rough opening before blocking, applying a sill pan in the bottom of the rough opening, and then installing the window or door. Portions of the side flashings on the top and sides of the rough opening are then bent over the side and top window or door flanges so that a portion of the side flashings may be adhered or otherwise fastened to the flanges to provide a seal.
