Tinting car windows
Here you’ll find answers to common questions about tinting car windows with window tint film — including legality, tint levels, and how easy it is to install.
Tinting car windows can be quick and affordable — or time-consuming and expensive — depending on the film you choose. For the best finish and comfort, pick a high-quality window tint film.
If you’re doing it yourself, pre-cut window tint film makes the job much easier and can save hours of work.
Frequently asked questions about tinted car windows
Is it legal to tint car windows with window tint film?
In many European countries, it’s generally legal to tint the windows behind the driver to any darkness level. The windscreen and the front side windows are usually subject to minimum light-transmittance requirements.
As a rule of thumb across much of Europe, the windscreen often needs at least 75% light transmittance, and the front side windows at least 70% (requirements vary by country).
If you still choose to tint the front side windows, we recommend avoiding very dark film. As a practical guideline, don’t go darker than 50% on the front, as it can make eye contact with other road users harder and reduce visibility in low-light conditions.
Why tint the windows of your car?
Most people tint car windows for sun protection and comfort. Quality tint film can reduce a large share of the sun’s heat, helping keep the cabin noticeably cooler — which is appreciated by drivers, passengers, children, and pets.
Many drivers also find they rely less on the air conditioning, which can reduce energy use. Tinted windows also add privacy and can help discourage opportunistic theft by making valuables less visible.
If you’re concerned about UV and IR radiation, window tint film can block a significant amount of both. If you spend long hours driving, this can be a comfort and wellbeing benefit. If you don’t want a dark look, lighter films are available that focus on heat and radiation reduction.
Can you tint factory-tinted windows with window tint film?
Yes. Factory-tinted glass is usually tinted within the glass itself (coloured/stained glass), so you’re not applying film on top of another film.
Even “clear” car glass often has a slight natural tint. Factory-tinted windows are typically darker than standard glass, though this varies by manufacturer and specification.
Which tint level should you choose?
If you choose a good-quality film, you can still get strong heat reduction and good visibility, even when driving at night. Choose tint level based on the look you want and how much privacy you need.
- 80%+: very dark (“limo look”), minimal visibility into the car
- 50–80%: dark appearance with some visibility
- Below 50%: more discreet, higher visibility
Lighter films are often chosen to reduce heat and radiation without noticeably darkening the glass — useful where front-window rules apply.
How much cheaper will it be to tint the windows yourself?
DIY tinting can save money compared with having a workshop do the job. You will usually save between 50%-80% of the cost of tinting the windows of a car by doing the job yourself compared to having a workshop do the job.
Is it difficult to tint the windows yourself?
It doesn’t have to be. If you choose a pre-cut, removable (adhesive-free) window tint film, you don’t need prior experience or special tools. Being careful, patient, and methodical is usually enough.
Adhesive film vs adhesive-free film — what’s the difference?
Traditional adhesive film is commonly polyester-based. On curved windows it often needs heat-shrinking and shaping to fit. It’s also sensitive to creases — once a crease is in the film, it can be very difficult to hide.
Traditional adhesive film typically requires more skill and specialised tools to achieve a flawless result — that’s why it’s often described as “professional film”.
Adhesive-free (removable) film is typically flexible and designed to conform to the window’s curvature without heat-shrinking, shaping, or joining. It attaches through static adhesion, can be removed and re-applied, and is far less likely to suffer permanent creases or trapped bubbles during installation — provided you work carefully and follow the steps.
Can you tint heated windows with window tint film?
Yes. Many modern cars have heated windows without visible heating lines, and tint film can be applied as normal. For windows with surface heating elements, tinting is usually fine as long as you avoid scratching the elements and make sure the film is properly applied so it adheres evenly.
A key tip: don’t switch on the heated window for a few days after installation so the film can dry and settle first.
