Reflective finish for glare and heat control, and daytime privacy

  • Reduces glare
  • Helps control heat gain
  • Cuts down UV light responsible for fading
  • Daytime privacy on the darker films
  • By the metre or cut to size

Purlfrost's reflective window film comes in 3 grades, a range of colours and exterior options, and can be applied to smooth glass on windows and doors, and the effects will be immediate. We also have a static cling reflective window film for temporary use, in rented accommodations for example. Other products in the range include coloured reflective films, extrenal grade reflective films and copper reflective films.

Why should I apply reflective window film to my windows and doors?

Mirror window film has long been the chosen solar control option for commercial buildings, due to its smart appearance and exceptional heat and glare reduction properties. These films are often specified to reduce the amount of visible light and glare which can affect staff working on computers, causing headaches and loss of productivity. Another benefit is the added privacy it offers during daytime hours, keeping prying eyes at bay and confidential documents safe. However, many people are realising the benefits of using reflective window film which can also act as a mirror window film for privacy, and as an insulation window film to help reduce heat loss in winter.

Which grade of 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. Please note that the light reflective film has hardly any privacy quality.

Is reflective film compatible with all glazing?

It all depends on how dark a film you require. For single pane glass, any film is suitable. It gets a bit more complicated with regards to double glazed units. If the pane you are applying the film to is toughened, then any grade of film is suitable. Otherwise you will have to select a lighter option. Please check the product's specifications and compatibilty data first. 

Will the film work on double glazed units?

Yes, the film will work just as well on single pane or double glazed units. However, for heat control, we would recommend an external reflective film as it is much more efficient at stopping the heat building up within the panes.

How does reflective window film work?

The film is both tinted and reflective. The tint controls the amount of visible light and therefore mitigates the amount of glare, the reflective quality of the film helps control short wave infrared responsible for heat gain, and by making the glass reflective, adds daytime privacy. It also stops 99% of UV light, helping protect your art pieces and furnishings from fading.

Is there a warranty?

Most of our window films come with a 7-year warranty, but they will last much longer.

How is film manufactured?

Most solar control tints are made of layers of different materials, and the reflective film is no different. This is what makes residential and commercial films different to car tints, as car tints are usually just dyed films.

Reflective film is made of the following layers:

1. "Hard" scratch-resistant layer, for durability and ease of maintenance during window cleaning

2. High optical quality polyester, with anti-IR metal particles deposit

3. Bonding adhesive

4. High optical quality polyester

5. Pressure Sensitive adhesive, glass polymerization within 15 days

6. Protection release liner, disposable after installation

How is 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. Please check out our video installation tutorials.

Which is best? Reflective or just tinted window film?

Reflective films tend to be much more effective than tinted films at preventing excess heat. Thanks to their metallised coating, they reflect sunlight and heat away before they penetrate through the glass making the room more comfortable. Tinted films are just as efficient when it comes to controlling excess glare, but without the reflective finish and the added privacy aspect. Internally, both types of film will look very similar adding a grey blue tinge to the glass. Like sunglasses for your windows.

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. Find out more about our range of window film installation and removal tools.

How do I clean reflective window 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.
