Understanding opaque window film and privacy for glass

How does opaque glass work?

The appearance of opaque glass can be achieved with an application of a window film, such as frosted privacy film. These types of privacy window films block the view and also have an impact on the light, scattering the light as it passes through the glass, instead of allowing it to pass through in a straight line. 

The light is diffused in multiple directions, creating a soft glow, instead of clear visibility. This effect delivers two key benefits:

  • Two-way privacy
  • Continued natural light inside

The actual level of light transmission will depend on a number of factors, including how bright it is outside on a particular day, along with the type of film used - different films allow different levels of daylight to pass through.

Frosted window film as an alternative to opaque glass

Is window film as good as opaque glass?

Opaque glass is usually chosen as a way of delivering two-way privacy. This can be achieved in two ways:

  1. Using permanent acid-etched or sandblasted glass.
  2. Applying an opaque or frosted window film to standard glass to achieve the same stylish look and privacy solution. 

Privacy window film is a more flexible and cost-effective solution as it can be retro fitted to existing glass, and can be removed at a later date if there is a requirement to return the glass to its original state.

Six benefits of using opaque window film for privacy

The Window Film Company offers a range of window films for privacy, including a number of high performance opaque options. Here's why you should consider one of these films to deliver your privacy solution, in residential or commercial settings.

Retro fitted

Opaque window film for privacy can be applied to existing glass, meaning there is no need for replacement glazing.

Immediate privacy

Once in place, the film is effective immediately, blocking the view from both sides of the glass.

Blocks the view, not light

While the film will block vision from both sides of your window, it will diffuse instead of blocking light.

Long lasting and durable

Our opaque window films have been developed for use in demanding and high traffic areas, including bathrooms.

Decorative upgrade

Opaque window film gives glass an easy to achieve but super stylish and contemporary new look.

Versatile privacy solution

Unlike acid etched glass, film can be removed and replaced if an alternative look or finish is required.
