Metal lamellae Solarfin CEL 600, Bibliothek Dußlingen

Colt Solarfin is a fixed or controllable external solar shading system that may be installed either vertically or horizontally in front of the facade. It may be combined with other Colt products such as rooflights and glazed façades.
A Solarfin shading system can reduce solar heat gain, lower air conditioning running costs, and lessen glare whilst maximising the use of natural daylight. With over 20 standard profiles, fins are available as one-piece extrusions in widths up to 400mm and as multiple clipped together extrusions in widths up to 1050mm.

Solarfin louvres may be fixed at any angle and can rotate under motorised control. Spans can be up to 6m without intermediate support and up to 10m with intermediate bracing rods. Fabricated and perforated fins are also available. All principal components are manufactured from extruded aluminium alloy type 6063 T6 with stainless steel fixings.
Controllable fins can pivot through 120 degrees and can be controlled by astronomical data operating the actuators to track the path of the sun.
