What is Privacy Window Film?

Privacy window film is a type of film that can be applied to commercial and residential properties. The end goal with this kind of window film is to increase the privacy of a property. Privacy window film is a cost effective alternative to replacing the glass in your windows where extra privacy is required. There are two main types of privacy film – One way privacy film and two way privacy film. 


One Way privacy window film 

One way privacy window film works by giving one side of the window a reflective appearance that you are unable to see through whilst still allowing vision from the other side. 

The film works on light balance, this means that the brightest side of the glass is the side that will display reflective properties. During the day time, this will always be the outside of the glass. At nighttime, if lights are on inside the property the effect will be reversed. As most people draw blinds or curtains of an evening this tends not to be an issue. 

This type of privacy film is most commonly used in a commercial setting and is a great alternative to blinds or curtains that block vision from both sides when closed during the day time. 


Two way privacy Window Film

Two way privacy window film is the best way of ensuring complete privacy on your properties windows. The most common form of two way privacy film is frosted film. When applied to a window, this film gives glass a ‘sandblasted’ effect meaning that vision is obscured from both sides of the glass. Frosted window film is available in a variety of patterns and can add cost effective, elegant look to your windows whilst ensuring privacy is maintained. 

In a residential environment, privacy film is a great alternative to net curtains or blinds. It is often seen on bathroom windows and doors where complete privacy is required. 



The traditional frosted privacy window film is now available in superb variations of patterned glass and diverse tints to best suit your offices’ style or building design. For example, our popular highly reflective window films come in a silver or bronze mirror effect, delivering one way enhanced privacy during daylight hours..

Guardian Window Film can apply window tinting to match the colour intensity and the amount of natural light you prefer. The films are easy to apply, ensuring a smooth and non-disruptive setup process. 

Our frosted window films are some of our most popular products as they have the ability to be as transparent as you like. If your space requires total privacy, this is simple to do and if the need for privacy is less, they can be adjusted to let more light through. Simply use our interactive tool to decide which is best for you. 



Through experience and innovation, privacy window films can now be tailored to meet a variety of additional purposes. You might simply wish to be a little more artistic and incorporate a subtle digital wallpaper print into your privacy window film. Alternatively, if you are looking to promote your products or services – then this decorative window film could be ideal for you.

A common example can be found looking at local football clubs or associations which often use digitally printed images and logos on their walls, exterior and interior windows for cost-efficient promotional campaigns.

So, if you have a need for privacy, you may as well make the best of it. Guardian has the latest window film technology, in order to give you the very best privacy. Our decorative film can make it truly unique for you or your business.

You can choose from a wide range of designs, finishes and styles. From etched glass and frosted glass film, to silver reflective window film, the options are endless. The privacy window film from Guardian works equally well in residential buildings.  You can play with colours and patterns to transform your living room glass windows into a work of art. 



At Guardian, we can print the images onto a variety of different window films. By printing onto a thicker safety film or security film, for example, we can help you protect your premises. Not only can we help you protect your property against vandalism and intruders, but we can also make your glazing compliant with health and safety regulations. 

Finally, our privacy glass films can also enhance the aesthetic appearance of your windows to lighten the atmosphere within your building. We can also print the images onto solar control film or energy control film to enhance privacy and reduce air conditioning costs.

    Frequently Asked Questions

    Privacy window film delivers one-way privacy by blocking the view into your property, or, in some cases, a specific area of your home or building. Reflective window film is generally used for building fronts facing public areas as it still preserves natural view from the inside during daylight hours. However, decorative and frosted film are more suited for indoors applications, such as on conference rooms or bathroom windows. 

    Although privacy window films are typically manufactured to preserve the optimal amount of light, they usually do affect light transmission. Whether you’ve chosen an opaque solution like frosted glass or a reflective film, the intake of light will be slightly reduced, but  one of our specialists will happily talk through our wide range of window film solutions and the varying light transmission features.

    Most privacy films for windows work equally well at night. For example, thanks to its opaque finish, frosted window film provides privacy around the clock, whereas mirror films only work during daytime.

    Depending on your requirements, you can choose from a wide range of privacy window films to suit your needs. 

    You can enhance the privacy in common areas of your home or office building using frosted film. Some customers also prefer adding in a decorative option to improve the aesthetic appearance of their premises or display a specific brand message. 

    In addition to hiding your assets from prying eyes, images can be printed onto a thicker safety film, which helps protect against vandalism and injury whilst still giving privacy from the image.

    Privacy window film can be applied internally or externally, but is typically applied on the inside surface of your windows due to access and weather conditions.  Generally, the internal films carry a longer manufacturer backed warranty as well as a longer shelf life.
