Safe and secure vertical sliding aluminium systems

Vertical sliding aluminium sash windows are a popular choice for installation in hospitals, schools, and other public buildings. They can be specified with anti-ligature hardware and are an essential requirement in many public sector buildings.

Vertical sliders provide excellent levels of ventilation without projecting vents. They have an optional tilt in function for easy cleaning access and can be manufactured up to 2700mm in height.

Top and side fixed lights can be coupled to the Sapa: Technal Vertical Sliders using the Sapa: Technal Dualframe Si 120mm fixed light system.
