Product information

Features and benefits

A wide range of system types - Ellisse can slide, hinge vertically, hinge horizontally or stay static. A wide range of louvre types are available, including extruded or sheet aluminium, Western red cedar or glass. The louvres inside the frames are able to be turned to a maximum of 85° by hand.

Robust - Ellisse is made from high grade aluminium and stainless steel and if the louvres and frames are operable, they are pivoted in UV-stable bushes and rollers. The system is designed to compensate for thermal expansion and is low in maintenance.

Potential for reduced installation costs – Ellisse can be provided in modular pre-assembled form.

Controlling Ellisse - The louvres and frames are operated either manually or by an electric actuator within a continuously sliding rail which is available in virtually any size. They can also be automated by a Colt sun tracking system such as ICS 4-Link or Soltronic.

Potential for reduced installation costs – Ellisse can be provided in modular pre-assembled form.
