Hunter Douglas transforms innovative folding system into flat closing sun screen

Hunter Douglas has developed its existing harmonica folding system into a fully flat closing sun screen system, powered by a spindle motor so that they can be opened and shut electrically.

It has taken this newly developed technique and also applied it to folding screens for curved façade elements on the front of the Fioretti College in Lisse, the Netherlands. Hunter Douglas’ fixed, horizontally sliding harmonica screens are not flat closing, but stand out at a slight angle in closed position. The powder-coated aluminium panels have a 12% perforation to reduce light fall and direct sunlight. The system blocks heat as well as light.
