Security window film is one of the most oversold products in commercial glazing, and one of the most useful when it is specified honestly. These articles explain what it actually does, which is hold broken glass together so that creating an opening takes longer, and what it does not do, which is make glass unbreakable, strengthen a frame or door hardware, or provide ballistic protection.
The distinction that matters most is rarely the film thickness. It is the attachment system. Film bonded to the glass surface alone behaves differently from film connected structurally to the frame, and the published test results show that difference clearly. Articles here cover attachment methods, what blast and forced entry ratings mean, why a rating belongs to a tested configuration rather than to a product name, and how to read claims that sound impressive but describe something other than the glass in your building.
Written for school administrators, facility and security directors, architects and the people comparing bids that all use the same words. Where film is the wrong answer, we say so and explain what the right answer looks like.
