Abstract: An insulated glass unit (IGU) comprises impact resistant safety films on the inner surfaces of the glass panes, providing an impact resistant, energy-saving IGU for use in windows and doors. A layer of the safety film providing energy savings may be trimmed from the edges of a glass pane; witch may be sealed within the interior of the IGU, preventing corrosion while providing no loss in impact resistance. A scratch-resistant, chemical vapor deposited coating may be added to an interior glass surface (i.e. facing the building interior) in order to prevent heat loss from the building. An IGU may have an Energy Star rating for both summer and winter use.

Abstract: A metallized coating is applied to a first surface of a multi-layered window film, the coating applied by vacuum deposition to form a laminated film composite. A second surface of the multi-layered window film composite is adhesively attached to a first glass pane. A thin outer edge strip of the outermost layer of the film coated with the metallized layer is removed. A second glass pane is prepared in the same way. The two glass panes are adapted to be mounted in a frame with the first surface of the film coated with the metallized coating facing each other spaced apart with a spacer. A sealant fills a cavity between the two glass panes to form an insulated glass unit.

Abstract: This invention concerns delivery vehicles entrapping active materials suspended in a water immiscible carrier. Methods of making these materials, preferably using a carboxymethylcellulose support martrix, are disclosed. The vehicles of the invention are especially well adapted to delivery of incompatible actives that can be entrapped separately and kept separately until release from the vehicle.
