Frequently asked questions

Manufacturing and product quality

How are your tinted window kits 'tailor-made'?

Our tinted window kits are made to measure as they are cut to the exact measurements of the vehicle's windows and then thermoformed onto the appropriate windows to give them the shape and curvature of the vehicle's windows. Whichever range of tinted films you choose, they all follow the same manufacturing process.

Are the pre-cut kits thermoformed to the shape of the windows?

All the films in our tinted window kits are thermoformed to make them easier to fit. The thermoforming of the film gives it the exact shape of the vehicle window.

Do you have window films for all vehicles?

Our database contains over 2500 models and we are constantly trying to expand it to meet all your needs.

My vehicle is not on the site, what should I do?

Our database contains the majority of European vehicles and is updated regularly.

If you cannot find your vehicle, please contact us by e-mail. We will do our best to find your vehicle.

Why do the films look crumpled?

The crumpled, "orange peel" appearance of the film is the result of thermoforming. Thermoforming heats the film so that it takes the shape of the glass. The heated film shrinks and takes on this crumpled appearance which will allow water to circulate between the film and the pane during installation. This simplifies the installation process. Once the film has been applied and dried, this appearance disappears.

Why does a solar film reflect heat?

Thanks to its thin metal layer, the solar energy is reflected immediately. This avoids the greenhouse effect.

What is thermoforming?

Thermoforming of automotive films is a technique that involves heating a film blank to soften it into the desired shape. Once cooled, the film retains the chosen shape.

How is thermoforming done?

From a film cut-out corresponding to the surface of the glass, the film is heated on the glass to a temperature of 500 degrees with a heat gun. The heating action allows the film to shrink. A Teflon scraper is passed over the film as it is heated so that it takes on the concave shape of the glass. This will make it easier to fit later.

What is the difference between thermoformable and thermoformed film?

The thermoforming films are sold in rolls or cut to size and must be thermoformed by you to fit the shape of the glass. The thermoformed films are prepared (heated on the glass) in our workshop. Thermoformed films are therefore more complicated to install because an additional step is necessary. For thermoformed films, the thermoforming is carried out in our workshop to make it much easier for you to fit tinted windows.

What is the difference between a roll of film and the tinted window kits Variance Auto ?

The difference between these two products is twofold:

  • The quality of the rolls of film is much lower than that of the films Variance Auto, whether they are sold in kit or cut to size. The films used by Variance Auto are of professional quality.
  • The 1st price film rolls are neither cut nor thermoformed (unlike the Premium and Essential kits Variance Auto). The customization of the kits Variance Auto greatly facilitates the installation.

What is the difference between an Essential kit Variance Auto and a Premium kit Variance Auto ?

Our Premium and Essential kits follow the same manufacturing process. They are cut to the dimensions of your windows and thermoformed to the shape of your vehicle. The difference lies mainly in the composition of the films and the additional services offered. The films of the Premium kits are more efficient and easier to handle. In addition, Premium kits usually come with a free installation pack and free delivery. The films in the Essential kits still offer effective protection and make it possible to buy at a low price.

Advice on film selection

Should the film be placed inside the car window?

Car films are only applied to the inside of your car windows. Watch the installation video [ with anchor to the installation video] to discover the correct way to install tinted window kits.

What is a safety film?

A security film delays break-ins and holds all glass fragments on its adhesive part if the window breaks. This film can be completely invisible or tinted.

Which films provide UV protection?

All films are UV-treated, so they all protect against ultraviolet light.

What are the best-selling colours?

To protect you from the sun at the rear, we recommend the "Medium 25" tint as it allows 51% of solar energy to be rejected while maintaining good visibility. To protect you from the sun at the rear, we recommend the tints "Medium plus 15" and "Dark 5", as they allow 15% and 5% of light to pass through, respectively, while allowing the view from the inside to the outside. For the front windows, we recommend "Extreme Clear 85" tint as it complies with the new legislation and allows heat and UV rejection. For more advice, follow our guides [].

Approval & warranty

How long will the films last?

The life span of the films varies from 2 to 10 years. It depends mainly on the type of installation, the installation conditions, the quality of the cleaning before installation and the quality of the installation. In general, the service life of a film is well beyond the guaranteed period.

How to apply tinted films

How easy is it to install for a private person?

The Variance Auto concept was designed to simplify the installation process as much as possible and make it accessible to everyone.

All you have to do is install them. It's up to you!

Are installation packs essential?

The installation package is highly recommended, as it will make installation easier and faster thanks to the appropriate installation tools.

Should the film be placed inside the car window?

Are there any alterations to be made?

No alterations should be made to the film before it is applied. Our cutting machine is accurate and our database is up to date and regularly checked.

Is it possible to apply film to other surfaces than glass?

The films Variance Auto must be applied only on mineral glass surfaces. For some cars, the quarter windows are made of plexiglass. Our film cannot adhere to the surface, so we do not supply films for these types of windows.

Once the installation is complete

When opening a window, does the friction of the seal on the window damage the film?

No. All our films are of high quality and scratch resistant.

Does the film prevent the use of the vehicle's de-icing system?

No, the film does not prevent the defrost system from working.

What precautions should be taken for the maintenance of films?

Do not use abrasive products or tools. The best solution is to use soapy water and a rubber scraper or soft cloth.

Can I easily remove the tinted film from my vehicle?

You can peel off the film by pulling on one of the corners. You should then remove the adhesive residue with a scraper or a copper sponge. If you want to apply a new film afterwards, we recommend that you do not use an abrasive solution

How to choose your wrapping films?

You can choose between wrapping 2D and 3D.

  • The wrapping 2D films are calendered films. They are generally used for flat or slightly curved surfaces. These vinyls are conformable but do not accept large deformations.
  • The wrapping 3D films are cast films. They are particularly appreciated to equip very curved surfaces with irregular shapes. They are suitable for curved car parts.

Can you install your wrapping yourself?

With the wrapping packs, installation is easy. Choose the references with a honeycomb structured glue for a crease and bubble free installation (reference with an "a" at the end). Thanks to this specificity, air bubbles can be easily expelled thanks to the small channels dug in the glue.

How to maintain your wrapping ?

The parts of your body covered with wrapping can be maintained in the same way as the rest of the vehicle. You just have to take care of the cuts and the joints: for that, we advise you against washing with a roller to avoid any delamination.

Is it possible to remove the wrapping ?

Yes, you can remove it at any time without leaving any traces on the bodywork of your vehicle. The adhesive used is specially designed so that you can return to the original bodywork at any time.

Is it possible to remove the Paint protection film ?

Yes, it can be removed at any time. It will not leave any marks on your bodywork.
