Safety & Security Window Film

Safety and security window film adds a layer to existing glass that can help hold fragments together if the glass breaks. For an Alliance home or business, that can reduce loose glass and add a measure of resistance during an impact. It does not guarantee protection against entry or injury. An installer should identify the glazing before recommending a film.

Security film can help hold broken glass together, leaving fewer loose fragments after an impact. It may also make it harder to clear an opening through the glass. The result depends on the glass and the complete window assembly, so film should be one part of a wider security plan. It cannot guarantee that a window will resist entry or prevent injury.

Use a soft cloth and a mild cleaner when caring for filmed glass, and avoid abrasive tools that could mark the surface. Follow the care instructions supplied for the film installed on your windows. If the film is cut, peeling or otherwise damaged, ask the installer to assess it.

Tempered glass breaks differently from other common glazing types, which can affect how a security film performs after impact. An installer should identify the glass and assess the full window assembly before recommending film for an Alliance property. Film alone does not guarantee that broken tempered glass will stay in the opening.

Laminated glass already includes a layer designed to help retain glass when it breaks. Whether an added security film is useful depends on the glazing and the goal for that window. Ask an installer to identify the existing glass before selecting a film. For related options,

The right security film depends on the existing glass, the window assembly and what you want to protect. Ask an installer to identify the glazing and explain which film suits the application. Compare the specific products under consideration rather than choosing by thickness or a broad claim of protection alone.

Security film may help keep broken glass in place during an attempted break-in, but it cannot make a window impossible to enter. Glass type and the surrounding window assembly affect the result. If you are considering film for an Alliance home, discuss the existing glazing and your concerns with an installer. For more on the options, explore our security film information.

The terms often overlap. Both safety and security film can help retain broken glass. A safety application may focus on reducing loose fragments, while a security application may focus on added resistance during an attempted entry. The appropriate choice still depends on the glazing and the property's needs.

Annealed glass can break into larger, sharp pieces. Security film can help hold those pieces together, but the outcome depends on the glass and window assembly. Have an installer confirm the glazing and recommend a film suited to the window's intended use.

How a film works after impact depends on more than the film itself. The glass, frame and edge conditions all matter. An installer can assess whether an edge attachment is appropriate for your particular window; it should not be assumed necessary or unnecessary from the glass type alone.
