Now you see it. Now you don't. Actually, the only time you'll Pella's award-winning Integrated Rolscreen is when you want to let in a breeze or a breath of fresh air. When you don't, it rolls away out of sight into the sill. Even better, when it's time to clean the window, simply release the sash and, as you tilt the sash in, the Integrated Rolscreen automatically releases and hides in the sill. Window cleaning done, return the sash to fully upright, and close the window.  The next time you open the window, the Integrated Rolscreen automatically reattaches, ready for more fresh air - with no hocus pocus!
