Casement windows are hinged at the side and open just like a door. They open further than any other window and use a hand-crank mechanism to operate. Casement windows are great for ventilation and can help provide a fresh breeze throughout our Indiana summer season, and all through fall. They are extremely stylish and versatile which may be why they are so popular near the Indianapolis area. Casement Windows are great alone, or you can build them into a Bow or Bay window.
