Sliding windows are a practical and affordable replacement window solution to any type of home. One or two sashes slide open horizontally to let in the breeze. With the single slider window, only one sash operates and tilts in for easy cleaning from inside the home. Single slider tilt windows are also available several configurations, making the window simple to operate, and easy to clean. For the double slider window, both sashes slide smoothly for flexible ventilation, and each sash tilts in for fast, safe cleaning from inside. It's a practical style that fits wide openings while keeping the look clean, modern, and easy to maintain.
