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.

Adhesive window film should only be applied to flat glass. It should never be applied to polycarbonate (plastic). We do not recommend that metalized (reflective) window film is applied to wired glass, double glazed units or highly tinted glass as thermal cracking can occur.

What is Adhesive Window Film?

Adhesive window films are constructed from a multi-lamination of micro-thin polyester. They also have a scratch resistant coating (SR) to protect the film surface and enhance durability (except films for external application).

Most films are applied to the interior surface of a glass window in a home, commercial building, or vehicle.  They have a scratch resistant coating on the outer surface to protect the film. Window film is specifically designed to protect windows from heat caused by sunlight, as well as IR and UV light. To do this, dyes and metals are layered between layers of polyester film which are bonded together. The type, amount, and quality of the dyes and metals used in the manufacturing process determine the quality, durability shade, colour, heat absorption, UV reflection, security, etc. of the finished product.

What are the Benefits of Window Film?

Window films have many benefits depending on film choice:

•Significantly reduce solar heat gain and temperature inside a building, vessel etc.
•Reduce air conditioning costs
•Extend life of HVAC systems by reducing maintenance and strain on the system
•Decrease environmental emissions
•Increase occupant comfort
•Reduce glare to improve visibility inside, especially for computer screens and VDUs
•Provide daytime privacy
•Block up to 99% of UV radiation
•Offer significant fade protection for soft furnishings, carpets, woodwork etc
•Improve building aesthetics and accent windows

Reflective / Mirror / Metalized Film

Metalized films provide a high amount of solar control because they reflect a lot of solar radiation. They get their name from the extremely thin metal layer within the film, usually aluminium. These films are made by vacuum coating a layer of metal onto polyester, then a clear laminate is applied to protect the metal. These are then sandwiched between an adhesive layer.  A UV inhibitor and a scratch resistant coating are also added.  Its shade and colour are mainly determined by the type of metal used to make it.

Metalized window film reflects more light than it absorbs and work on a ‘daylight privacy’ basis. Viewing through the film is effective from the ‘lower light level’ side of the film. This means, when these films are applied to windows facing outside people can see out of the room during normal daylight hours, but people cannot see inside easily. However, the situation is reversed at night. A ‘mirror effect’ then occurs when looking out of the window so it is much easier to see into the room than out of it, so if the inside is illuminated and the outside is dark then the film loses it’s one-way vision properties. These films can provide some privacy at night depending on the lighting arrangement inside the building, but if you want 100% privacy then blinds or curtains are still required.

Reflective films give a shiny metallic look to the outside of buildings.  This can be an attractive feature when coupled with modern architecture but it is not to everyone’s taste and the reflected dazzle/glare can be a problem.  Reflective films can also cause interference with radio, GPS and cell phones.

Reflective films are the best option if solar control is the overriding consideration in hotter climates, and people inside do not mind the slight reflections you get at night.

Non-Reflective or Dyed Film

Although they are non-reflective since they do not include any metals, these films  provide heat and glare control through solar absorption. Dyed films come in a variety of colours and are usually produced by applying a dye to the polyester base film along with a UV inhibitor. There are several product benefits associated with dyed films. They provide increased optical quality and clarity through strong glare control and, all things being equal, the dry out time is shorter than for a film with a metal layer.  It’s important to note that dyed films are less effective in controlling solar heat gain because they control heat by absorbing solar energy.  The heat absorbed by the film is transferred to the glass, then dissipated outward with the movement of air. Metal films reflect the solar energy, so they are more effective. Non-reflective films tint the glass with a low sheen finish which means there isn’t a highly mirrored appearance from the outside. The light balance will depend on whether you can see through the film from either side.  Very dark tints make the films more difficult to see through.

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.


Window films filter out over 99% of UV rays, reducing the main factor in fading. However, additional factors such as solar heat, visible light, humidity, and the presence or absence of chemical vapours also contribute to fading. Therefore, the greatest protection from fading is offered by tinted or metalized window films that reject larger levels of heat and visible light, in addition to UV.

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.
