- Security window film holds shattered glass together, helping delay forced entry and reduce injuries from flying shards.
- The film does not prevent glass from breaking, but makes the damaged panel harder to break through.
- Selected films also offer UV protection, reduced heat and glare, and greater daytime privacy.
- Professional assessment and installation help ensure the film suits your glass, frame and security needs.
Glass windows bring natural light into your home and help create bright, open living spaces. However, standard glass can also be a weak point in your home security. If an intruder breaks a glass panel, they could reach a lock or gain entry to the property.
Quality security window film adds an extra layer of protection without significantly changing the appearance of your windows. Depending on the product selected, it could also provide UV protection, reduce glare, improve privacy and support better energy efficiency.
In this guide, we explain what security film for windows is, how it works and the benefits it provides for your home.
What Is Security Window Film?
Security window film is a multi-layered polyester film bonded to the inside surface of a glass panel using a strong adhesive. It is thicker and stronger than standard decorative or solar window films and is designed to keep shattered glass together following an impact.
The film does not stop the glass from breaking. Instead, it changes how the glass behaves after it breaks. Rather than immediately collapsing into loose glass fragments, the broken glass remains attached to the film.
This helps protect people from flying shards while leaving a more difficult barrier for potential intruders to overcome. The additional time and effort needed to break through the glass and film could discourage an attempted break-in or delay entry until help arrives.
How Does Window Security Film Help Deter a Break-In?
Many intruders want to enter a property quickly and attract as little attention as possible. An exposed glass window or door could provide a direct route into the home, particularly if breaking the glass gives the intruder access to an internal lock.
Security film helps protect against this type of forced entry by keeping shattered glass attached to the film. Even after the glass has broken, the intruder must continue striking, pulling or cutting through the damaged panel to create an opening.
Window security film also helps protect occupants from:
- Accidental impacts
- Children falling against glass
- Objects striking windows
- Storm debris and extreme weather
- Sudden glass failure
These safety and security benefits make the film suitable for residential windows as well as commercial buildings, offices, schools and other busy properties.
What Are the Other Benefits of Security Window Film?
Although security is the main reason many homeowners install window film, selected products offer several additional benefits.
UV protection
Quality window films help block harmful UV rays passing through the glass. Selected high-quality window films can block up to 99% of the sun’s UV rays.
UV protection helps reduce fading and discolouration affecting flooring, furniture, curtains, artwork and other interior materials. It also provides an added layer of protection for people spending time near sun-exposed windows.
Improved energy efficiency
Some security films also provide solar-control and insulating properties. They help reduce the amount of heat entering through the glass during warmer weather and limit heat loss during cooler periods.
This can make indoor temperatures easier to manage and reduce the demand placed on heating and air conditioning. Energy efficiency will vary according to the type of film, glass and building orientation.
Reduced heat and glare
Tinted security window film helps reduce uncomfortable glare and harsh sunlight entering living areas. This is particularly useful for rooms with large west-facing windows, television screens or home office workstations.
Reducing solar heat also helps create a more comfortable indoor environment without covering the windows and blocking all natural light.
Additional privacy
Selected tinted films provide greater daytime privacy by making it more difficult for people outside to see into the property. This helps conceal valuable items and reduces opportunities for potential intruders to inspect the interior of your home.
What Is 3M Security Window Film?
3M security window film is a range of safety, security and solar-control films designed for installation on existing glass.
Clearview Security offers 3M window film in clear and tinted options for your home or business. Depending on the selected product, the film helps retain broken glass, improve resistance against unwanted entry, block UV rays, reduce glare and limit heat transfer through windows.
Some 3M films use multiple micro-thin layers arranged to provide strength without requiring a bulky or highly visible covering. This makes them suitable for homeowners looking for added protection that maintains the appearance of their windows.
How Is Window Security Film Installed?
Professional installation typically follows these steps:
- Assess the window: The installer checks the existing glass, frame and surrounding area to determine the most suitable film and installation method.
- Measure and cut the film: Each glass panel is measured before the film is cut to fit its exact dimensions.
- Clean the glass: The window is thoroughly cleaned to remove dirt, dust and residue that could affect the finish.
- Apply the film: The film and adhesive are applied to the inside surface of the glass.
- Remove air and moisture: The installer removes trapped air and excess moisture to create a smooth finish and secure bond.
- Secure the edges if required: Depending on the system, an additional attachment method might be applied around the edges to connect the film more firmly to the window frame.
- Allow the film to cure: The film needs time to dry and settle. Temporary cloudiness or small moisture pockets might appear during this stage.
Installation generally causes minimal disruption and does not require the entire window to be replaced. The time required depends on the number, size and accessibility of the glass panels.
