Horizontal Slider windows provide great ease of opening with the option to have the sash sliding left or right. Unlike crank-style windows, Horizontal Slider windows offer convenient use for all. As they slide open without protruding, horizontal sliders are an excellent choice for rooms facing walkways, porches or patios. Horizontal Slider windows are a favorite for contemporary style homes and addressing bedroom egress requirements. On a single slider model, one sash slides to open. In a double slider model, both sashes open.  This feature great for providing air circulation to a room.
