Single Sliding Windows Over Low Lites

Description Create striking vertical lines and add natural light with the versatile and stylish Single Sliding Windows Over Low Lites by Jason Windows. Designed for Perth homeowners, renovators, and builders, this configuration pairs a top-sliding window with fixed bottom panels, providing a balance of privacy, ventilation, and design flexibility. Also referred to as split-pane windows, two-lite vertical sliding windows, or twin-sash sliding windows, this style is ideal for bedrooms, bathrooms, stairwells, or any area requiring light at a lower level and ventilation above. The top sash slides open to promote airflow, while the fixed lower panels maintain privacy or allow daylight to enter — an ideal solution when low-level openings aren’t feasible or desired. Constructed from durable, low-maintenance aluminium, our aluminium sliding windows are built to perform in Western Australia’s demanding climate. They’re available in a selection of popular powder-coated colours, including White Lustre, Silver Lustre, Anotec Dark Grey, and Charcoal Lustre. Custom sizes and colours are also available upon request if your project requires a more bespoke solution.
