Frequently Asked Questions

Visible Light Transmittance. This is a measure of the amount of light that passes through a substrate. For example: a 35% VLT film will be able to transmit 35% of visible light through the film. Glass in todayʼs vehicles typically will measure between 70% to 75% VLT with no tint even installed. This means that if your stateʼs law says you have to be at 35% NET you must combine the film and glass measurement together. If your glass meters at 75% and you install a 35% film on this window, it will meter a little over 26% after installation, making it illegal. In this specific example, youʼd need a 50% Film VLT to comply with your State or Territory.

TSER means the percentage Total Solar Energy Rejection. This equals solar heat reflectance plus the amount of solar heat absorbed that is then re-radiated outwards and is rejected from passing through glass. When comparing how much heat a film rejects, we should compare TSER (UV+Visible Light+IR)

OZ Window Films and Global Window Films carry a lifetime warranty to the original purchaser with receipt of installation. All installations must meet local State or Territory legal limits, as with any film manufacturer. The lifetime warranty will cover you for defective film. The warranty does not cover poor quality installation, damage from misuse, improper cleaning, or poor maintenance of door mechanisms.

Your professional installer will provide instructions and recommendations. In the Australian climate, we recommend that you leave the window rolled up for 2 days.

Observe your window film at about 1 to 1.5 Meters. Most fresh tint applications will take up to 30 days to fully cure. During this time the windows may appear hazy and or streaky. There may be small water pockets caused by excess moisture trapped between the glass and the film. Do not squeegee, prod or poke these water blisters, they will disappear once all the water has evaporated.

Though most professional installers strive for perfection, and only highest quality in their installations, due to the nature of the product and degree of dust contamination, minor imperfections are present in every window tint application. There may be pre-existing flaws or scratches on the glass that are often much more noticeable after the windows are tinted. In some cases, it could be hard water stains on the outside of the glass that was never noticed prior to your tint installation.

You can wash your car when ever you feel like it. You cannot clean the inside of your windows for 14 days.

Most cars have a ceramic "frit" edge on the rear window. Sometimes this ceramic edge is straight and flat, and sometimes it will have a dotted edge, these black ceramic dots are quite thick on most cars and will prevent the film from sticking to the between glass near or between the dots. This results in a whitish looking strip trimming the glass. Typically this isn't very noticeable but on certain cars it may be.

Some late model cars have Privacy Glass on all the windows behind the two front doors. Privacy Glass is made by using a dye during the manufacturing process. Privacy glass does not offer the same UV protection or heat reduction that a quality window film offers.

The two front windows are not tinted simply because the windows behind the two front doors have Privacy glass from factory. Unlike window film, privacy glass does not provide the same ultraviolet (UV) protection or heat reduction qualities. Window film offers 99% UV protection against both UVA and UVB rays. Privacy glass provides protection against UVB rays because UVB rays cannot penetrate any kind of glass including non tinted glass. OZ Window Films highly recommend contacting a professional installer in your area.
