This article breaks down the types of security window film and their underlying mechanisms without diving too deep into the technicalities.

Security Film for Windows - Overview

  • Security window film reinforces glass, making it more resistant to breakage and keeping it intact during break-ins, and it includes benefits such as reduced UV exposure and protection of interior furnishings.
  • There are various types of security window films, such as anti-shatter, bomb blast, UV protection, and privacy films, each designed to meet specific needs like improving window strength, blocking harmful rays, or enhancing privacy.
  • Choosing the right security window film involves assessing specific needs, comparing product reviews and ratings, and possibly consulting an expert, with the installation process being vital for the film’s effectiveness and lifespan.

Understanding Security Window Film

Here is a little bit of background on what security window film is so you know what you are getting before making the purchase.

Also referred to as glass safety film, security window film is a transparent, self-adhesive film product adhered to the inside of glass windows or glazing. Its primary role is to enhance the security of your property. When applied, it reinforces existing glass, making it more resistant to breakage.

This added layer of protection not only makes the glass harder to break but also keeps it intact, even in the event of breakage, acting as a deterrent to would-be intruders.

Security window film has undergone rigorous testing and has been shown to effectively deter burglars and thieves, making it a worthy addition to any security system.

The film is designed to hold shattered glass fragments together, making it harder for intruders to gain entry and reducing the risk of injury from flying glass shards in the event of a break-in.

Besides its strong security features, security window films also have added bonuses like:

  • Reducing UV ray exposure
  • Protecting your property’s interior from the harmful effects of the sun
  • Prolonging the life of your furnishings
  • Reducing the risk of skin damage

Safety Window Film Advantages

If the film isn't actually adding anything to your home, then it becomes pretty useless, doesn't it? Luckily, there are tons of benefits that security window film can add to any property.

For any property owner, security window films are an excellent investment due to the numerous benefits they offer. Holding broken glass shards together makes it significantly more difficult for intruders to gain entry, thus increasing the overall security of your property.

This protective layer also reduces the potential for injuries caused by shattered glass, a feature that is particularly useful in homes with children or in commercial settings such as schools and offices.

Beyond these safety benefits, security window films also offer energy conservation benefits. Enhancing the thermal efficiency of your property is achievable by applying these films to existing windows and doors, thus lowering energy costs and fostering a more sustainable environment.

For an even higher standard of energy efficiency, you can look at window insulation film, which is designed to be extremely energy saving.

The Active Film Clear Safety & Security Window Film is one such product that offers these advantages. Along with providing protection against shattering glass, it also offers a visually seamless finish that closely resembles the window, thus not compromising on the aesthetic appeal of your property.

Types of Security Window Films

Like almost everything, there is room to choose and customise your security film before buying it.

Each is designed for specific needs, and security window films are available in various types. These include anti-shatter films, bomb blast window film, UV protection films, and privacy films.

Anti-shatter films, such as the Active Film Clear Safety & Security Window Film, work by strengthening the glass, significantly increasing its resistance to break-ins and holding glass fragments together in the event of breakage.

UV protection films, on the other hand, offer up to 99% protection against harmful UV rays, ensuring clear glass visibility while adhering to health and safety standards.

If your needs revolve around privacy, there are privacy films specifically designed to obstruct visibility from the outside, offering an added level of window protection and privacy.

These films block the view into your property without compromising on natural light, making them a popular choice for both residential and commercial properties.

Upgrading to Safety Window Film

Opting for safety window film is a cost-effective strategy to strengthen your property’s security and energy efficiency. Unlike full window replacements, these films can be applied directly to existing glass windows and doors, providing a more economical solution.

Certain safety window films, such as the Active Film Safety & Security Window Film, also offer up to 99% UV protection. This feature not only enhances the security of existing glazing but also protects your interior furnishings from fading due to prolonged exposure to sunlight.

These robust films are designed to last for years without requiring replacement, making them a worthy long-term investment for your property. The process when you upgrade existing glass involves the following:

  • Applying the film to your existing glass
  • Effectively elevating it to safety glass standards
  • Avoiding the high costs associated with full window replacements

Select the Right Security Window Film for Your Home

Safety Window Film

So, going through all of that might be a lot to take in, but it gives you a lot of options to choose from to get the perfect safety film.

The process of selecting the best security window film for your home entails assessing and comparing various options. This includes understanding your specific needs, comparing product reviews and ratings, and consulting with an expert.

Let’s delve deeper into these important steps, including full-fitting instructions.

Consider Your Specific Needs

Start by assessing your specific needs when selecting the right security window film. Are you primarily concerned about break-ins? Perhaps you’re looking to protect your home from harmful UV rays, or maybe privacy is your main concern.

If prevention of break-ins is your primary concern, anti-burglary protection films are a worthy consideration. These films are specifically designed to enhance the strength and resilience of your glass windows, offering robust protection against potential intruders.

You can further enhance your security by installing window bars, although there is a common debate on astragal bars vs Georgian bars and which one is better.

On the other hand, if privacy is a major factor for you, frosted window films may be the perfect fit. These films create an opaque finish that obscures visibility from the outside while diffusing light and maintaining a stylish appearance.

It’s also important to consider the type and location of your glass, as well as the level of security needed when selecting the right film for your home, especially if you need to hold the glass in place during a potential break-in.

Compare Product Reviews and Ratings

After identifying your specific needs, proceed to research and compare product reviews and ratings. Reliable reviews can be found on various online platforms such as and

When interpreting product ratings, it’s important to consider factors such as:

  • Safety ratings and standards
  • The cost-to-benefit ratio
  • The film’s effectiveness in addressing specific threats such as theft, vandalism, or natural disasters

In addition, consider the following factors when choosing a safety window film:

  • The film’s ability to improve the security of standard glass
  • Its resistance to break-ins and vandalism
  • Its role in accident prevention
  • The variety of safety window films offered
  • The thickness of the film
  • Safety certifications
  • UV protection
  • Warranties
  • Performance evaluations
  • Adherence to fire regulations

Consult an Expert

Seeking professional guidance can greatly assist in choosing the correct security window film for your home. A security window film expert can provide insights into:

  • Strengthening glass against break-ins and burglaries
  • Offering enhanced privacy
  • Providing UV protection
  • Reducing glare
  • Improving energy efficiency
  • Enhancing the aesthetic appeal of your property

Window Security Film Installation and Maintenance

Whenever you get your security window film, the next step is installation, but always make sure to do this right, on top of maintenance. This way, your glass safety film will be as effective as possible.
