Smart windows, on which the level of visible light transmission can be electrically switched, are produced by laminating a special switchable film between the two layers of a glass laminate The film is made by sandwiching an emulsion containing the switchable variable light transmission active material between a set of electrodes. One of the challenges of producing said laminates is preventing the migration of plasticizers and moisture from the plastic bonding layer of the laminate into the emulsion where it can degrade performance. By applying a sealing member to each electrode layer along the periphery the emulsion is protected and in a manner that facilitates automation of the process.
