Hello jhurst, the "Zap Pack" line of windows are made by Jeld-Wen, and if you are considering Andersen windows, they make a pocket window, it's their 400 Woodwright series. They are available in custom sizes on the 1/8" inch & because they are called Pocket windows, they are inserted into your old frame and you can get a screen. The Zap Pack window provides you with a upper & lower sash, 2 jamb liners, parting bead that goes at the top of the opening, and mounting clips, but you cannot
get a screen with a Zap Pack window.
The biggest positive of the Zap Pack window is that you will probably increase your visible glass area, which will give you a little more light. Anytime you add an pocket frame, something that has a complete frame around the unit, and it's inserted into the old frame, you get less light, and makes the window look smaller.
If you drive around your neighborhood, I'll bet you can tell who has a pocket window replacement by the small size of the glass. Something to consider. BTW, the Zap Pack window and Andersen 400 WoodWright series windows are available at your Home Depot.
