External grade solar control window film

  • Controls excess heat, glare 
  • One way mirror effect for daytime privacy
  • Available in 2 grades

Our Exterior Reflective Film is designed to go on any flat glass surface and ideal where glass is not suited to internal film, or when internal access is an issue. You can also use it on glass banisters.

Reflective window film, also known as Mirror Film is by far the most effective window film when it comes to excess sunlight and glare. Purlfrost's reflective film comes in 2 grades, can be applied to most glass surfaces and the effects will be immediate.

How does reflective film works?

The clue is in the name. The film reflects excess sunlight away from the glass, and stops short wave infrared which makes it super efficient. It also stops 99% of UV light, saving your art pieces and furnishings from fading.

Is there a warranty?

Our external reflective films come with a 3 year warranty, but they will last much longer.

How is exterior window film applied?

The film is a self adhesive material applied using a soapy water solution and a squeegee, making bubbles a thing of the past. When installing externally, make sure you do it on a dry day with little wind.

What is mirror film?

Mirror film is just another name for reflective window film. It is widely used on office windows to offer extra daytime privacy. The reflective quality of the film will also offer varying levels of privacy, when used on exterior facing windows. The darker the film, the more reflective it is, and the more privacy it will offer. However, the privacy effect will only work during day time hours.

Can I remove the film at a later stage?

Absolutely. You will need a spray bottle and some soapy water, and as wide a glass scraper as you can get. 

How do I clean the film?

Just clean with soapy water and a squeegee, that's all. Do not use anything abrasive on the film or it will scratch it. Wait for 4 weeks after installation before you clean the film.

Frequently Asked Questions
  • Which grade of external film should I choose?

    As a rule, we recommend the darker films for south facing windows, where the sun is harsher. East facing windows will be exposed in the morning, when the sun is low, and west facing windows in the afternoon when the sun is high, but brighter. North facing windows shouldn't be too affected by the sun.

  • We need privacy

    Thanks to its reflective quality, and especially the dark version, the film will give you some privacy during daytime hours, and you'll be able to clearly see out whilst passersby will struggle to see in unless they come right up to the glass.
