Adjustable sill pan assembly and system

Abstract

An adjustable sill pan assembly that includes a sill pan formed of components engageable in a manner enabling length adjustment. The sill pan includes a rail that is adjustably engageable with corner pieces. In addition, the rail can be cut to length and coupled to another rail using a connector. A preferred pan rail includes an upraised back dam flange and a sill overlying panel over which a wicking sill liner is placed for enabling moisture in the region of the pan between a sill and window to be expelled. One or more spacers carried by the back dam flange bear against an interior surface of the window frame to maintain a flow channel between the back dam and window further facilitating moisture removal. The pan assembly can be used in conjunction with liquid and gas impervious tape to prevent infiltration. One preferred pan assembly embodiment is of caulk-free installation.
