Abstract: A window assembly having a window frame and at least one primary sash mounted in the window frame. The primary sash has a plurality of sash members forming a primary sash perimeter and a first glazing panel mounted in the primary sash perimeter. At least one secondary sash is pivotally attached directly to the primary sash perimeter along an interior surface thereof so that the secondary sash is rotatably movable between a closed position and an open position relative to the primary sash. The secondary sash has a plurality of secondary sash members forming a secondary sash structure and a second glazing panel mounted in the secondary sash perimeter. An air chamber is located between the primary sash and the secondary sash that is substantially closed to the interior of the building structure. At least one accessory channel is locating along at least one side of the secondary sash members.

Abstract: An edge protector for a fenestration product is integrally formed of a sing le sheet of corrugated paperboard that has been perforated, slit, scored, glued , and folded in a particular manner so as to be generally flat in overall configuration prior to being placed in use. At the time of installation, the protector is partially unfolded out of its flat plane to assume an overall generally transversely L-shaped configuratio n, having a pair of legs intersecting one another at right angles to form a receiving corner for the face and side margins of the product. One leg of the protector forms a flap that covers a marginal portion of the face of the product when the protector is fitted onto the product, while the other leg forms a second flap that covers a marginal portion of the sides of the product. A stiff, relatively short spacer flange comprising a double layer of the material glued together projects edgewise from the outside of the corner in the opposite lateral direction from the side flap to keep the face of the produc t spaced away from foreign objects. Wrapping of the protector around an outside corner of the product is facilitated by the provision of tear-out tabs embodied in the face flap s o that the appropriate tab aligned with the corner of the product may be torn out to leave an emptynotch in the flap at that location. The absence of material at the corner of the product eliminates the structural rigidity otherwise afforded by the face flap at th at location to enable the protector to more readily bend around the corner.
