Abstract: A protective device for a glazed structure, in particular an aircraft windscreen 20, comprises at least one removable sacrificial sheet of transparent composite 10. The composite 10 comprises a transparent polymeric film 11 having on one side an electrically conductive layer 12 formed from a dispersion of electrically conductive particles and which is coated with a transparent hard coat 13, with the other side having adhesive layer 14 thereon. Sheets of the composite 10 may be arranged in a stack so that each sheet adheres to the adjacent underneath sheet with the uppermost sheet of each stack being removable as the sheet becomes damaged and/or dirty.

Abstract: Now, according to the present invention, performance solar control films are provided that are effective at reducing the transmission of solar radiation without also detrimentally affecting the transmission of radio waves or other wavelengths that are used for communication, such as for satellite communication or cell phones. Solar control films of the present invention comprise a polymer film onto which a layer of non-stoichiometric aluminum oxide has been formed.

Abstract: Now, according to the present invention, composite solar control films are provided that are effective at controlling solar radiation while also presenting an appealing coloration. Composite solar control films of the present invention comprise two or more polymer films bonded together, wherein at least one of the polymer film layers comprises a layer of non-stoichiometric aluminum oxide.
