Single Slider
Single-slider windows feature one operable sash that glides horizontally while the opposite sash stays fixed, offering a compact, space-saving ventilation solution. Designed for smooth operation and minimal upkeep, the single-slider windows provide energy-efficient performance and expansive glass areas that maximize natural light.
Double Slider Windows
Double-slider windows have two horizontal, independently sliding sashes for adjustable ventilation and easy interior cleaning. They offer energy-efficient, smooth operation, a sleek profile, large glass area for more natural light, and a modern, attractive look.
Three Lite end Vent Slider
The three-lite slider is specially tailored for wide openings, potentially replacing several windows as well as associated framing to gain the most of available sunlight. Both end sashes slide towards the centre for ventilation and tilt inward making them easy for you to clean.
