I have been researching escape windows, too. Ours is half of a 24 by 48 window. We want the entire window to be an escape one. The useable space on ours is only about 18" high, including the red latches we would need to crawl over, by 24 " wide. Since we have Hehr windows I called their customer service. Problem we are running into is that you can't get a matching frameless escape window in our size, so we would have to go to a framed one. A framed slider escape window with a hinged top would run between $550-$600, but the entire window opens for easier exit. All Rite makes a custom after market framed escape window, but they wanted over $1600 for it!
Still hoping to locate another option that would more closely match our frameless windows. Not looking too hopeful!! Check with your window manufacturer first. If you have framed windows, you may have more options! Please post what you find. Thanks!!
