Sill pan flashing detail

Sill Pan Flashing – a type of flashing used at the bottom of window or door openings to prevent  water from infiltrating into the wall framing or interior of the structure.  When used in conjunction with header and jamb flashing it effectively prevents minor leaks or decay of the window or door units from adversely affecting the structure.

Sill pan flashing may be custom fabricated from metal or plastic stock, either in shop or on site.

Adjustable sill pan flashing is also commercially available; usually consisting of two or more pieces that are sealed together once they are trimmed to fit the opening.

Pliable sill pan flashing, also commercially available, consists of a water proof membrane with a thick adhesive backing that adheres to the sill and jambs.  It must be trimmed and pressed in place to attain the proper shape required to flash the opening.
