How to Choose Tinted Film for Car

Many car owners are confused when choosing car window films: How to choose tinted film for car? Is it the darker the better? What exactly is the difference between the expensive ones and the cheap ones? These questions seem simple, but they involve the quality of the film material, the standard of light transmission rate, and the usage environment. If one doesn't understand these, it's very easy to choose only based on appearance, neglecting safety and comfort.

Car window tinting is not only an aesthetic modification but is also closely related to sun protection and heat insulation, explosion protection, driving safety, legal compliance, and daily comfort. This article will gradually analyze the key points of choosing window film, combining professional advice and common misunderstandings, to help you select the most suitable window film solution for yourself.

 

Types of Window Tint Films

There are numerous types of car window films on the market, and their performance and prices vary greatly. When choosing, car owners must make a judgment based on their own needs and budget. The following are the four common types of car window films:

a. Dyed Film

This is the most basic and cheapest type of car film.

• Advantages: Low price, rich color options, and can improve the appearance of the vehicle.
• Disadvantages: Poor heat insulation and UV protection, short lifespan, and prone to fading.

It is suitable for car owners with limited budgets who mainly pursue appearance, but it is not recommended for long-term use.

b. Metalized Film

Adding metal particles to the film layer can enhance the heat insulation performance.

• Advantages: Good heat insulation effect and strong durability.
• Disadvantages: May interfere with electronic signals such as GPS, mobile phone signals and radio reception.

It is suitable for users who have a need for heat insulation but have a relatively low reliance on electronic devices in the vehicle.

c. Carbon Film

The use of carbon fiber particles avoids the problem of metal interference.

• Advantages: Non-reflective, excellent heat insulation performance, strong UV blocking ability, and long service life.
• Disadvantages: The price is higher than that of dyed films and metal films.

Striking a balance between performance and price, it is suitable for mid-to-high-end models and car owners who pursue durability.

d. Ceramic Film

It belongs to high-end membrane materials and is made of nano-ceramic particles.

• Advantages: It has excellent heat insulation and UV protection performance, blocking 99% of ultraviolet and infrared rays, and does not interfere with signals.
• Disadvantages: It is the most expensive.

It is the best choice for both performance and comfort, especially suitable for luxury cars and car owners with high requirements for the interior environment.

 

Key Factors to Consider When Choosing a Film

Choosing window films is not as simple as "the darker the color, the better". What really matters is the comprehensive performance of the film material in multiple aspects such as thermal insulation, safety, legality, appearance and lifespan. The following points are the core factors that car owners must consider when making a choice.

1) Heat and UV Rejection

The key indicators for evaluating the performance of the film include:

• SPF (Sun Protection Factor): Indicates the skin protection capability.
• IRR (Infrared Radiation Resistance Rate): Determines the heat insulation effect.
• UV Resistance Rate: Affects interior aging and skin health.

For instance, Veintone high-end ceramic film can block 99% of ultraviolet rays, effectively protecting the skin and preventing leather and plastic interiors from fading or cracking due to sunlight exposure. This is the most important purchasing criterion for car owners who frequently drive in hot or sunny areas.

2) Visible Light Transmittance (VLT, Visibility & Legal Regulations)

VLT (Visible Light Transmission) represents the window's light transmittance.

• The lower the light transmittance, the darker the membrane becomes, providing higher privacy, but the night vision may be limited.
• The higher the light transmittance, the clearer the vision becomes, but the privacy decreases.

The laws in various regions have specific regulations regarding the light transmittance of the front windshield, side windows and rear windows:

For example, some states in the United States stipulate that the front windshield should have at least 70% VLT, while the rear windows and rear windshields can be made deeper. In China, in most regions, it is required that the front windshield and front car windows have a light transmittance of ≥ 70%.

Before making the choice, it is necessary to confirm the local regulations to avoid fines or failure of annual inspection due to non-compliance with the film application.

3) Aesthetics & Privacy

Car films are not only functional products, but also determine the overall appearance of the vehicle.

• Dark Film: Enhances privacy, suitable for car owners who value a low-profile and spy-proof design.
• Light Film: More in line with the original factory style, providing better visibility while driving.

It is recommended to make the choice based on both the car paint color and the character of the vehicle model. For instance, a white car paired with a light gray coating appears cleaner, while a black car combined with a dark coating appears more stable.

4) Durability & Warranty

The lifespan of different grades of car films varies significantly:

• Low-end film: It is prone to fading and bubbling within 1 to 3 years.
• High-end film: It maintains stable performance for 7 to 10 years.

High-quality brands usually offer manufacturer warranties, such as those from 3M, Avery Dennison, and Veintone. The warranty covers features like color retention, crack resistance, and bubble prevention, which can effectively ensure the user experience.

5) Cost

The price range is approximately as follows:

• Entry-level membrane: $100 - $200
• Mid-range membrane: $200 - $500
• High-end ceramic membrane: $500 - $1000+

Cheap films may seem cost-effective at first glance, but they often have poor heat insulation and short lifespan. In the long run, they cost more. For instance, a $150 low-end film might need to be replaced every 2 years, while an $800 ceramic film can last for over 8 years. Overall, it's more economical.

6) Construction Techniques (Installation Quality)

Even for high-end membranes, if the construction is not done professionally, problems such as bubbles, edges lifting, and knife marks may occur.

• The construction environment should be a cleanroom to prevent dust particles from affecting the bonding process.
• The technicians should have extensive experience to ensure that the edge treatment and heat shrinkage process are carried out properly.

The construction process determines the final effect and lifespan of the vehicle film, and is an equally important factor as the quality of the film material.

FAQ

① Will applying a film affect the visibility at night?

It depends on the transmittance of the membrane. High-quality ceramic film features excellent light transmission properties. Even for light-colored models, it can maintain a clear view at night. However, if you choose the dark-colored tinted film, the visibility at night will significantly decrease, increasing the driving risk.

② Are there significant differences between cheap films and expensive films?

The difference is extremely obvious. Cheap films usually have poor heat insulation and low UV protection effect, and their lifespan is only about 2-3 years. High-end films (such as 3M, Avery Dennison, Veintone ceramic series) can achieve 99% UV blocking, and remain colorfast for 7-10 years, making them a more cost-effective option in the long run.

③ Can I still drive and have my vehicle inspected after applying the film? 

The key lies in whether the visible light transmittance (VLT) complies with the regulations.

For instance, in most regions of China, the light transmittance of the front windshield and the front windows is required to be ≥ 70%. Similarly, different states in the United States have their own specific standards.

Veintone offers compliance solutions to ensure that the light transmittance of the membrane material complies with local regulations.

④ Will applying a film damage the glass?

No. The car film is attached to the inside of the glass and does not alter the glass itself. However, if an inferior film is chosen, there might be remaining glue after removal, which requires additional cleaning. High-quality membrane materials can be reliably removed without any damage under professional operation.

⑤ How often should it be replaced?

It depends on the quality of the retina material.

• Low-end film: It may start to fade and bubble within 2 to 3 years.
• High-end film: Generally, it maintains stable performance for 7 to 10 years, and sometimes even longer.
