Abstract
Abstract A transparent thermal insulating system having controllable transmissivity to visible radiation comprising a first layer generally transparent to visible radiation, a second layer generally transparent to visible radiation and spaced from the first layer; partition means for separating the space between the layers into compartments; a thermal radiation suppression device for suppressing thermal radiation transmission; and a variable transparency thermal control device for controlling transmisson of visible radiation as a function of temperature.
