Casement Windows

This style of window is designed to slide horizontally from right to left and/or left to right. Some styles (double sliders) are made in such a way that both panels (sashes) operate. Others (single sliders) have only one operating sash (the other is fixed into the frame and cannot be opened). Some sliders have a tilt-in feature which allows one or both sashes to be tilted into the room, allowing for easy cleaning of the exterior panes of glass from inside the home. Some sliders are not equipped with the tilt-in feature and are thus called lift-out sliders. The sashes for lift-out sliders need to be physically removed from the window frame for cleaning.
