Ecoline S & Highline S sliding door
Slim profiles equal more light and a room with a view
The aluminium profile systems Ecoline S and Highline S sliding doors provide an unbroken, uniform profile sight line, with an edged profiling and a slim sight line of just 55 mm in the panel butt joint.
Within a wintergarden glazed extension the glass level of the sliding door fits flush with connected elements such as fixed windows and bi-folding doors, so there is no major offset at the edge of the glass.
Ecoline S: 2700 mm max. panel width x 2500 mm max. panel height. Highline S: 3200 mm max. panel width x 2800 mm max. panel height.
For both sliding doors, the accessible floor track comes with a built-in, cascading system drainage and is equipped with a stainless steel locking handle with a latch function. The handle locks in place when in the vertical position, so it can be used to pull the sliding panel.
Durable stainless steel rollers, the same as the cero family's tried-and-tested carriage and running tracks, provide ultra-convenient operation thanks to light sliding action.
