thermotropic

thermotropic

Materials that undergo various property transformations in response to heat and temperature changes, including conductivity, transmissivity, volumetric expansion, and solubility. Visibility in thermotropic windows is directly controlled by climatic temperature changes. However, there are no visual changes to the window at low temperatures. Therefore, during the winter these windows allow solar light and heat to penetrate undiminished into the building. See also: Smart materials
