A double sliding window allows two of the three sashes to slide open, offering maximum flexibility and airflow. It’s ideal for wider openings or areas where access and ventilation are priorities. In contrast, a single sliding window features only 2 sashes, where one is fixed and the other opens. Are triple sash sliding window options available? Yes. We offer configurations that include a central fixed sash with two sliding sashes on either side, commonly referred to as triple sash sliding windows. Can I order custom sizes or colours? Yes. While we stock a wide range of standard sizes and popular colours like White Lustre and Charcoal Lustre, we also offer custom sizing and powder-coated finishes to suit any project.
