Abstract Tilting double hung window construction, including a single plastic guide member at each side of a window sash for providing compression between a window frame and the window sash mounted therein and weatherstripping therebetween, as well as guiding the window sash in sliding movement relative to the frame and twopart pivoted camming and locking structure for securing the window sash in a tilted vertical position, especially in conjunction with counterbalance structure which is readily engageable with and releasable from the counterbalance structure. The window construction further includes unique single member glazing and mullion extrusions for facilitating glazing of the window structure and the sealing of window structures positioned side-by-side. Shipping clips for maintaining the frame of the window structure within predetermined limits during shipping and installing are also disclosed.
