Double Slider Windows
A horizontal window where both sashes operate, gliding left and right for flexible ventilation and a wide, low-profile viewing area — a smart choice for openings where side-to-side operation is more practical than raising a sash.

Wide, easy-gliding horizontal ventilation
Double slider windows operate horizontally — both sashes glide along a track so you can open either side for flexible, left-to-right airflow. With no cranks or vertical lifting, they are effortless to use and well suited to wider openings and spaces where raising a sash is less practical.
- Both sashes glide left and right along the track
- Flexible ventilation from either side of the window
- Wide, low-profile viewing area
- Smooth operation with no cranks or vertical lifting
- A great fit for openings wider than they are tall
