One Way Window Film

With a mirror like finish, one way window film restricts the view in for daytime privacy, whilst allowing you to see out. Choose between our dark, medium, light or non-adhesive one way window film options, all available by the metre or cut to your exact measurements. 
Our one way window films are mainly designed for anti-glare and heat rejection. But thanks to the reflective quality of the mirror window films, they have the added bonus of offering daytime privacy by reflecting sunlight, thus turning your windows into virtual mirrors. The films are ideal for home or office.

Please beware that the Dark grade films are only suitable for single pane glass, or double glazed units when made of toughened glass, not laminated.

AB left a new 5-star review of Purlfrost Window Film:

I have used frosted foil and one way mirror foil in my flat. I followed the instructions, read them and watched videos, as I was applying the foils for the first time. All worked really well and I am very happy with the final result! It is important to apply soapy water, especially when removing the protective layer from large pieces. It is also very important to remove even the tiniest specks of dirt on glass. I took my time to reinspect all areas for any bubbles left. I noticed that if there were bubbles left at edges which kept reappearing, it was due to foil stretched over the edge of the glass (was too big) and I had to cut it there for perfect fit. But it was all worth it, both doors and a window look as if they were made that way. 

Frequently Asked Questions
  • How does one way window film work?

    One way window film works when the outside ambiant light level is higher than the level in the room, which is why the effect only works during daytime hours. As a rule, the darker the film, the better the reflective effect is, but the more natural light will have to be sacrificed.

  • What is one way window film?

    One way privacy window film is applied to your window and doors to give the glass a mirror finish, adding instant daytime privacy. One way films were primarily designed as solar control films for glare and heat reduction, as well as UVs responsible for the fading of furnishings and art works.

  • What are the limitations of one way window film?

    The main principle is that the light level internally has to be less than the light level externally, making this product only suitable for daytime privacy. So if your windows face North or if there's a lot of shading due to trees or other buildings, it is unlikely the film will work to its full effect. And at night, the film will have no reflective quality and therefore offer no privacy from the outside.

  • Can one way film be applied to any windows?

    Window film can be applied to any smooth, non-textured glass, including double glazed units. There are some restrictions when selecting the dark one way mirror films which are explained in more detail on the products pages, so if in doubt, select our medium one way mirror film which is ideal for all types of glass, mitigates the loss of natural light and is still very effective.

  • Is one way privacy window film easy to apply?

    All our films are supplied with a free application tool and a full set of easy to follow instructions. Feel free to view our video tutorial for tips on how to apply small and large pieces of film.

  • Is there a film that offers privacy at night?

    Fot the privacy effect to work at night, you will need to restrict the view in by applying a glass obscuring film like a  frosted window film or any other types of privacy films. A good alternative could be a patterned window film which can be ordered with a clear pattern within a frosted background, allowing you to see out during the day whilst restricting the view in at night from the outside.
