Abstract: A window frame profile for forming into a window frame with a number of other similar profiles includes a separate nailing strip extruded from aluminum and attached to the outer surface of the frame profile. The nailing strip includes a planar strip member and a cylindrical bead portion along one side edge of the strip member. The bead is snap fastened into a cylindrical recess in the outer surface of the frame allowing rotation of the strip about the axis of the bead from a retracted position for transport in which the strip is received in a flat recess on the outer surface. The strip can be rotated from the retracted storage position to an erect position at right angles to the outer surface by rotation about the axis of the bead and snap fastened in the erect position.

Abstract: A window frame system includes four basic profiles for new building construction and for various other projects including renovation, bow and bay constructions. One profile includes an outer profile for engagement with the wall of a new building in which the distance between the inside wall of the profile and a nailing fin is at least 6.5 inches. The height of the profile is then reduced to accomodate this larger width. A cross mullion is provided and a sash frame profile is also provided. The inner wall of the outer frame and the side walls of the mullion are arranged for cooperation either with a picture window unit or with the sash frame. The fourth profile comprises a renovation/bow profile which can be inserted into an existing window frame or can be snapped together alongside similar profiles to form a bow or bay construction.
