Abstract
A laminated glazing unit has controllable transparency to visible light and a solar load reduction element which preferentially excludes infrared radiation while being substantially transparent to visible light. Electro-active material for controlling the transmission of visible light through the glazing unit is sandwiched between electrodes deposited on facing surfaces of plys or layers of an inextensible polymeric material, such as polyethylene terephthalate. One or both electrodes comprises a solar load reduction ('SLR') element, i.e., a Fabry-Perot interference filter which includes preferably at least one silver metal film sandwiched between zinc oxide films.
