Folding, Sliding, & Tilt-TurnWindows Kolbe is well known in the window and door industry for innovative products. Our two pass-through window options – folding windows and quad sliding windows – are the perfect way to blend indoor and outdoor living spaces. Double and triple sliding windows are also available for situations when space is at a premium. Tilt-turns lend a modern twist to a classic European window, with special hardware that allows them to open as a top-venting hopper window or an inswing casement.
