anti-fog window film


The problem of windows and glass surfaces fogging up due to temperatures and the steaming up effect can affect many areas. Our anti-fog window film have been specifically designed to help in these situations.

We offer two types of anti-fog window film, depending on your situation:

Hydrophilic – This window film absorbs any water that comes into contact with the surface. This way a clarity of vision remains through the surface. You will often find it is typically used on the inside of glass fronted freezer display units in supermarkets.

Hydrophobic – This type of window film rejects the water that comes into contact with it, running down the surface. You will often find that this is typically used for bathroom mirrors.

Put a stop to the fog with our anti-fog window films. Contact our team today and we’ll be happy to assist with your specific requirements.

Important Information

Not all films are suitable for all glass. The absorptance of the glass and the film, the size of the pane, the thickness of the glass and the construction of the window should be considered in terms of single pane, insulated glass, treated (with a low-emissivity coating), laminated or toughened.

Advice on the appropriate selection of film for the glass is vital to ensure that the glass does not crack as a result of thermal stress. However, it is possible that a pane of glass may break subsequent to the application of an appropriate film, because the glass pane has been damaged during the glazing of the window, or as a result of movement of the building or other physical stresses that are not apparent at the time of the film application.

The chances of glass breakage occurring subsequent to the application of film is very small. However breakage can occur and it is impossible to predict the edge condition of the glass without removing it from the frame – an approach that is not practical.

Anti-fog window film should only be applied to flat glass. It should never be applied to polycarbonate (plastic).

Drying or ‘Curing Out’ Time

The performance of window film is not fully effective immediately. A ‘curing out’ period should always be allowed of up to 30 days after installation when the remaining application solution between the film and glass evaporates.  During this period the film is still performing to its full solar control and safety capabilities. As the film begins to dry out, it is common to see bubbles, haze, streaks, and other visual defects in the film as it cures.  This is completely normal, and these will disappear as the film dries out. 


Firm ‘squeegeeing’ is vital to reduce or eliminate a ‘clouding’ effect caused by water condensation during the ‘curing’ stage. If clouding occurs it should only take a few days to clear completely. Drying conditions, however, should be adequate, including room temperature and ventilation, otherwise clouding can remain for a longer time.

‘Light Lines’

A ‘light line’ is a gap left around the edge of the window film (approx. 2 – 3mm) after application to the glass. It ensures that the solution used to apply the film can be more easily removed when ‘squeegeeing’, and avoids the potential for water and suspended dirt particles to move under the film by capillary action. It also ensures that the installed film does not touch the frame margin which could lead to lifting and peeling of the film.

Water Bubbles

Tiny water bubbles between the film and glass are normal. About 10 – 15% of the moisture stays between the glass and film immediately after installation. This moisture will disappear through condensation as the film is porous. Bubbles that do not disappear can be removed by bursting with a fine needle or sharp utility knife.


‘Inclusions’ are small particles of dust trapped between the film and the glass and should be removed by peeling back the film from the glass and flushing out using water, before the adhesive begins to take effect.

Maintenance / Cleaning

The cleaning process for a filmed window is similar to unfilmed glass. Before cleaning make sure that the film has fully cured.  We recommend waiting 30 days before cleaning after the film is installed.  Use a soft clean cloth, soft paper towel or clean synthetic sponge that is NOT abrasive. Soapy water or a normal glass cleaning solution which contains no abrasives is fine to use.  Dry with a soft clean cloth.


All films are covered by a manufacturer’s 5-year Guarantee against peeling, cracking, demetalization and delamination.
