Where glass and glazing is concerned, anchoring systems are present in some safety and security glazing systems and attach window film to the glass or to the frame of the glazing. Anchoring systems can be wet glazed or mechanically attached.
A wet glaze attachment is where the manufactured seals on the glazing are removed and security or safety window film is applied all the way to the edge of the glass. A new sealant is applied, securing the film and glass in place in the frame.
A mechanically-attached anchoring system physically attaches the security or safety film to the frame. The film is applied to the interior surface of the glass with an overhang that is either screwed into the frame or that is held in place with an anchor that is glued to both the glass and the frame.
