One Way Window Film

With a mirror like finish, one way window film is a privacy window film allowing you to see out as if the glass was clear. You can choose between our dark, medium and light graded adhesive window film, or our static cling one way mirror film options, all available off the roll by the metre, or cut to your exact measurements for ease of application. One way privacy window film has a charcoal colour when looking through the glass from the inside, similar to a tinted window film, and the mirror finish is seen externally. As a rule, the darker films are more reflective and more likely to add the one way privacy effect allowing you to see out whilst restricting the view in. 

  • For daytime privacy
  • Easy to apply to windows and doors
  • Available by the metre

With a mirror like finish, one way window film is a privacy window film allowing you to see out as if the glass was clear. You can choose between our dark, medium and light graded adhesive window film, or our static cling one way mirror film options, all available off the roll by the metre, or cut to your exact measurements for ease of application. One way privacy window film has a charcoal colour when looking through the glass from the inside, similar to a tinted window film, and the mirror finish is seen externally. As a rule, the darker films are more reflective and more likely to add the one way privacy effect allowing you to see out whilst restricting the view in. Do make sure you check your privacy window film is compatible with your glass, especially for older double glazed units where the glass might not be toughened.

Daytime Privacy 

One way mirror film is primarily designed for solar control and to act as a window tint to reduce heat, glare and UV light (the main cause of fading of furnishings). Thanks to the reflective silver finish, one way window film not only rejects solar heat but as the sun hits the mirror finish, it allows you to see out whilst blocking the view in from the outside world. The reflective mirror effect only works when the light is brighter outside than it is inside, so in the evening or at night when the lights are on inside your house or office, the privacy effect no longer works. One way mirror window film is therefore only suitable for privacy during the day, and more so on brighter or sunnier days. If for instance your windows are facing North with no sunlight hitting the mirror window film, the privacy benefit will be negligible.

Glass Compatibility

One way vision film is suitable for application on smooth non textured glass. Care must be taken when selecting one way film for double glazed windows as the darker grades are not suited to units where the glass is not toughened or tempered. Make sure you read the specifications for all the products before making your selection. if in doubt, order a film designed for exterior application. External films are also much more effective at controlling excess heat as the stop the heat from going through the glass and getting trapped within a double glazed unit.

Reduces Glare & Excess Heat

Do you find yourself struggling to look at your TV or phone screen on a sunny day? We all face this problem at some stage during the day or year, and traditionally we would all have reached for the blinds, curtains or shutters to ward off the sun for heat reduction. One way window film, is a very efficient alternative to blinds, allowing a controlled amount of light through thus making the room more comfortable. As well as a reduction in glare, one way window film will help reduce the amount of heat generated by the sun and coming though the glass, or worse, building up within the double glazed unit of your windows. Solar window film also stops 99% of UV light helping reduce the fading of fabric on furnishings, carpets and rugs, and wooden floors.

Curtains and blinds tend to trap the heat and heavy fabrics contribute to making the rooms hotter or stuffy. Though practical in essence, you have to sacrifice a lot of daylight by completely blocking the sun to achieve a similar level of comfort that you will benefit from with one way window film.

For Privacy Day & Night

If you are looking for a glass covering to give you privacy both during the day and at night, we would recommend a glass obscuring film like a  frosted window film or other similar 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. You could also apply a frosted film strategically so that it only covers the critical part of your window that offers you the privacy required. Typically, covering the bottom half of a bay window is sufficient.

Temporary One Way Privacy

If you are looking for a temporary solution for enhanced privacy or solar control, we supply a medium and a dark grade static cling reflective window film which are very easy to apply. The main advantage is that due to the lack of glue, the films are very easy to remove and in some cases can be kept and re-used at a later stage.

Frequently Asked Questions
  • 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.

  • 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 a reflective film which when applied to your windows and doors, gives the glass a mirrored finish and instant daytime privacy. One way window films are primarily designed as solar control films, mainly for glare and heat control, as well as the reduction of UVs responsible for the fading of furnishings.

  • Does one way window film work at night?

    Unfortunatelly, due to the lack of daylight, one way window film will have no reflective quality and therefore offer no privacy at night especially when the inside is illuminated.The privacy benefit will only take place when daylight reflects off the mirrored finish of the film. You must also consider that 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 either.

  • 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.
