RE: Box Blind Windows
i install windows all the time so have ton of old frames laying around . find someone who does this in your area ,they will more then likely have something laying around that will work for you. i just use a wide wooden sash ,like half of a kitcken window,add hinges on top and screw it on . then take a piece of 4-5in roof flashing and flash the thing to keep it from leaking.
