Variablecolour Plastic Films

Dichroic plastic films cause the observed colour and opacity to change depending on the viewpoint, also on the direction and intensity of the light source. For example, one dichroic sheet changes between green, gold and orange; another between purple and blue. These films can be used to make the external envelope or internal environment of buildings appear to be active.

Thermochromic pigments in fibre-reinforced plastic sheet cladding change colour with the temperature allowing the building to visually respond to outside temperature. The thermochromic pigment is incorporated into the core fibres and the gel coat to gain maximum effect.
