Abstract: The present disclosure concerns a foundation window assembly comprising a window frame comprising a plurality of frame members, and at least one casing connector arranged on at least one of said plurality of frame members; and a window casing comprising a plurality of casing members defining together a frame-receiving opening, wherein at least one of said plurality of casing members defines a frame-abutting shoulder at least partially delimited by a casing flange portion and a frame-engaging portion. A frame-engaging recess is formed in the frame-engaging portion, the frame-engaging recess at least partially circumscribing the frame-receiving opening, the casing connector being removably engageable into the frame-engaging recess when the window frame is inserted into the frame-receiving opening. The present disclosure also concerns a method for installing a foundation window frame into a foundation wall.
