Horizontal Sliding
Our horizontal sliding system is engineered for flexibility across a wide range of commercial window configurations, delivering slim sightlines, smooth operation, and reliable long-term performance.
Configured with 2, 3, 4, or 5 independently sliding sashes, the system provides generous access for cleaning and maintenance, and controlled ventilation, while maintaining a discreet appearance.
For larger or more demanding openings, our Enhanced range offers the same core benefits, with heavy-duty framing and self-supporting panes that ensure stability and strength across larger glass units.
Can be coupled or stacked with other units in the range to cover large glazing areas or long runs of windows. 49dB (Rw), when using 6mm toughened primary glazing and 6.8mm acoustic laminate secondary glazing. 1.5 W/m²K when using 4mm toughened Low E glazing and 80mm spacing between the primary and secondary window. Note: all sizes are for guidance only, and depend on several factors (including glass and subframe). Units and styles outside of those listed are sometimes possible – please contact us for advice. Our manufacturer's Sheffield-based has its own painting plant, allowing you to choose from a comprehensive palette of more than 200 powder-coated RAL colours to achieve a precise match with your Granada secondary glazing system. Suitable for new developments, heritage buildings, and complex commercial environments, our finishes are specified to meet the requirements of each project.
