2141217 9402313 PCTABS00030 A light admitting thermal insulating structure (10) having controllable transmissivity to visible radiation (11) comprises a first layer (15) generally transparent to light, a second layer (17) generally transparent or absorptive to light and spaced from the first layer; an improved partition means separates the space between the layers into compartments; a thermal radiation suppression device (16) for suppressing thermal radiation transmission; and a variable transparency device (18) for controlling transmission of light. A suitable partition includes a novel convection baffle which transmits light and thermal radiation which improves the thermal resistance and/or reduces the cost of low emissivity layers (16).
