Privacy window films are a great way to enhance privacy in both commercial and residential properties. However, their effectiveness at night depends on a few different factors.
We know how important it is for businesses to have the peace of mind that their premises are as secure as possible, especially during the darker months – here’s everything you need to know about using window film for privacy at night.
How does privacy window film work?
In the daytime, most privacy window films use their reflective surfaces to create a one-way mirror effect. This is most effective when the outside is brighter than the inside, so during the day, the sunlight reflects off the window film, making it much harder to see indoors.
Lighting conditions are the most important factor when it comes to the effectiveness of reflective films, as it’s the side of the window film that is being exposed to the brightest light that will essentially take on the privacy properties. This means that at night, if there are any lights on indoors – even if it’s not a particularly brightly lit room – the one-way effect is essentially reversed, and people will be able to see inside the property.
So, whilst reflective window films can offer some degree of privacy at night, it is dependent on the lighting conditions. Although many offices and commercial properties turn their lights off at night, there is still a chance that the interior lighting may be brighter than the outdoor lighting, depending on the external light sources.
Types of privacy window film
As well as reflective window film, there are several other types of window film available that can help to bring more privacy.
Frosted window film
Frosted window films create a translucent effect that blurs the view on both sides of the window without sacrificing natural light. Although they are probably most commonly used for bathroom windows, frosted film is also ideal for conference rooms, offices and partitions. Plus, frosted window film works just as well at night as it does during the day.
Blackout window film
Blackout window film is exactly what it sounds like, a fully opaque window film that blocks all visibility. Although this is great for privacy, blackout films don’t let in any light, so it is only really suitable for areas that require total privacy, like storage rooms.
Decorative window films
Another popular option are decorative window films, which are available in a wide range of patterns and gradients. They help to obscure the view and provide privacy but just with that bit more aesthetic appeal.
Switchable or smart films
Switchable and smart films are advanced window films that can switch from transparent to opaque at the touch of a button, using liquid crystal technology. Like traditional window films, they are applied directly to glass surfaces, but switchable and smart films are powered by electricity.
When they are in a transparent state, they let in natural light and visibility, but when they are opaque they provide total privacy. These types of films are most commonly used for spaces that need a bit more confidentiality, like conference rooms and executive offices.
How to improve privacy in your office
There may not be a window film that will totally obscure the view inside your commercial property (unless you’re willing to sacrifice all of your natural light!), but it will definitely help to improve the privacy in your workplace.
For enhanced privacy at night, window films can be combined with extra protection such as blinds or curtains. Professional installation can also make a difference to how well your window film works, as poorly fitted window film can lead to uneven coverage.If you’re looking to improve the privacy in your commercial property, we’d be happy to talk you through the best type of window film for your needs.
