Transparent edge sealed window films substantially minimize (if not eliminate entirely) degradative effects on the window film, particularly solar-reflecting metals and/or oxides associated with multilayer window films, caused by ambient conditions (e.g., commercial window cleaners, salt and the like). The edges of window films are preferably sealed by a liquid solvated polymeric material which, upon curing, provides a solid transparent seal which significantly minimizes the degradative effects of the ambient environment. Most preferably, the window film whose edges are sealed will include a transparent thermoplastic (e.g., a polyester) film layer and a solar-reflecting metal and/or oxide applied onto a surface of the film layer. The sealant for such a preferred window film will be a polyester-type sealant which has silane end-group functionality and substantially no free isocyanate groups.
