Automotive insulation film is a type of film designed to reduce heat for car windows. This film can be applied to all glass surfaces of a car, including the windshield, side windows, cabin windows, rear window, and roof (sunroof). Automotive insulation film is typically made from polyethylene terephthalate (PET), combined with various processing methods to enhance its heat-reduction capabilities.

Features of NanoX Automotive Insulation Film

NanoX automotive insulation film offers 7 outstanding features: up to 90% high-efficiency heat rejection, 100% infrared rejection (IRR), 100% ultraviolet rejection (UVR), exceptional transparency, glare reduction, privacy protection, and glass safety.

High-Efficiency Heat Rejection (Up to 90%)

Total Solar Energy Rejected (TSER) exceeds 90%. NanoX automotive insulation film acts as a shield, not only regulating part of the visible spectrum but also almost completely eliminating infrared rays. The film absorbs solar energy and reflects it back, preventing heat transmission from the outside into the vehicle.

Infrared Rejection (Up to 100%)

Infrared Rejected (IRR) reaches 100%. NanoX automotive insulation film can completely block infrared radiation. Unlike traditional films, NanoX does not rely solely on reducing light transmission for heat rejection but instead filters out infrared rays. Infrared radiation is the largest contributor to heat in sunlight, so NanoX offers light-colored windshield films that ensure visibility while maintaining high heat rejection efficiency.

Ultraviolet Rejection (Up to 99%)

Ultraviolet Rejected (UVR) reaches 99%. NanoX automotive insulation film integrates a UV-filtering system to block UV rays from penetrating the glass. This protects the health of users from skin and eye damage caused by UV rays and minimizes UV damage to vehicle interiors, especially leather components such as dashboards, seats, and steering wheels.

Exceptional Transparency

Haze level below 1. This is one of the most outstanding advantages of NanoX products, especially for windshield insulation films. NanoX films can achieve maximum heat rejection while maintaining exceptional transparency. The Nano Ceramic X-Shield technology allows light to pass through the film while minimizing light scattering, providing the best visual experience for drivers.

Glare Reduction

Glare reduction (Reduced Glare) of up to 40% for windshields and over 90% for other areas. NanoX automotive insulation film can reduce intense light sources such as sunlight or oncoming headlights, allowing drivers to see more clearly and reducing eye strain by minimizing the need for adjustment.

Privacy Protection

Visible Light Transmittance (VLT) reduced to as low as 5% for side and rear windows. NanoX offers a variety of films for side and rear windows with different VLT levels ranging from 30% to 5%. The lower the VLT, the better the protection against outside visibility, enhancing both privacy and security when vehicles are parked in public areas.

Structure and Working Principle of NanoX Automotive Insulation Film

NanoX automotive insulation film consists of the following functional layers:

Protective Nylon Layer for Adhesive: Printed with the full film code and genuine NanoX logo.
Adhesive Layer with Integrated UV Filter: High-quality specialized adhesive that incorporates a UV filtering system. Its properties remain stable even under high temperatures.
PET Layer: Supplied by a leading global PET manufacturer, meeting strict standards for quality and transparency. The PET production process includes film coloring to ensure durability and resistance to fading.
Nano Ceramic Layer: A heat-rejecting functional layer made of multiple ceramic particle layers with nano-sized particles, capable of maximizing the elimination of heat-inducing infrared radiation (IR).
Scratch-Resistant Layer: A functional layer designed to protect the film surface from scratches during use.

Working Principle of NanoX Automotive Insulation Film

The working principle of NanoX automotive insulation film is based on controlling solar heat radiation through a ceramic coating. This material features an extremely dense crystalline structure, with atoms bonded by strong covalent chemical bonds. This structure forms a barrier that prevents the movement of phonons—thermal energy carriers—through the film.

Ceramic has excellent infrared radiation (IR) absorption and reflection capabilities. When sunlight hits the glass, most of the heat is contained in infrared radiation. Therefore, blocking infrared radiation effectively prevents heat from being transmitted into the vehicle.

NanoX Automotive Insulation Film Production Technology

NanoX automotive insulation films are manufactured using Nano Ceramic X-Shield technology. This technology is developed based on advanced material science and is specially optimized for Vietnam’s climate conditions.

Nano Ceramic X-Shield employs inorganic ceramic material as its primary production component. The ceramic offers outstanding advantages, including high thermal insulation performance, excellent resistance to harsh environments, user-friendly and health-safe properties, and no interference with signal reception.

Preparation

Cut the film and prepare protective coverings.

Film Cutting

Measure and cut the film according to the glass template.

Heat Shrinking

Heat shrink the film for the windshield and rear glass to match the curvature.

Glass Cleaning

Clean and remove all dust and debris from the glass.

Film Application

Apply the film to the glass, remove excess water, trim edges, and refine details.

Inspection

Check, clean, and organize the workspace.

Final Acceptance

Verify quality and hand over to the customer.

The ceramic particles undergo a high-precision firing process, achieving an extremely small size of just 28 nm (compared to the common range of 50–100 nm) and high purity. This results in the formation of ultra-durable bonds that not only extend the film’s lifespan but also enhance its ability to absorb and reflect solar radiation in the final product.

Experience in Choosing Automotive Insulation Film

Types of Automotive Insulation Films

Automotive insulation films include 5 main types:

Dyed Tint Film: Made by dyeing PET. This type of film blocks heat by darkening the glass, preventing light from passing through. The advantage is its low price. The downside is that it has relatively low infrared radiation (IRR) and ultraviolet radiation (UVR) rejection, and its durability is also relatively low.
Metalized Tint Film: Made by coating PET with metal, typically aluminum or nickel-chromium. The advantage is its low price and better heat insulation than dyed films because metals have good heat reflection properties. The downside is its low durability (prone to oxidation) and the potential to interfere with signals.
Sputter Tint Film: Made by using rare gas ions to deposit metal in multiple layers on PET. The metals used in sputtering are usually of higher quality than those in metalized films, such as gold, silver, or titanium. The advantage is excellent heat reflection. The downside is the high production cost, which results in a higher price.
Nano Ceramic Tint Film: Made by applying multiple layers of nano-sized ceramic material onto PET. The advantage is excellent heat absorption, high durability, transparency, safety for users (no metals), and a reasonable price.
Hybrid Tint Film: Made by combining two of the four technologies above. This combination helps eliminate the weaknesses and enhance the strengths of each technology. Hybrid films often combine dyed films with metalized films or nano ceramic films with sputter films.

So, which is the best automotive insulation film today? Nano ceramic and multi-layer sputter films are the most commonly used. However, sputter films are quite expensive. In contrast, nano ceramic insulation films are more reasonably priced while still providing excellent heat protection, making them more popular.

Specifications of Automotive Insulation Films

When choosing automotive insulation films, you should pay attention to the following key specifications:

Total Solar Energy Rejected (TSER): Indicates the level of heat rejection through the glass of the film.
Infrared Rejection (IRR): Indicates the level of infrared radiation rejection through the glass of the film.
Ultraviolet Rejection (UVR): Indicates the level of ultraviolet radiation rejection through the glass of the film.
Visible Light Transmission (VLT): Indicates the level of brightness or darkness of the film.
Visible Light Reflectance (VLR): Indicates the level of reflectivity of the film.

Color of Automotive Insulation Films

Automotive insulation films come in various colors, with the most common being: brown, gray, blue tint, and green tint. You can choose the color based on your needs, preferences, or the overall color scheme of the vehicle.

Glass Positions

An important tip when choosing automotive insulation films is to select the type of film suitable for each glass position:

Windshield: To ensure clear visibility, the windshield film should have a visible light transmission (VLT) of 50% or higher; high transparency (low haze); maximum infrared rejection to increase total solar energy rejection; and a slightly gray or blue tint to reduce glare.
Front Side Windows: To ensure clear visibility of side mirrors, the side window films should not be too dark, with a VLT of 15% or higher.
Rear Side Windows/Rear Window: These positions are less strict with VLT. For maximum heat rejection and privacy, you can choose dark films with a low VLT of 5-20%. If you want more natural light inside the car and easier outside visibility, you can opt for films with a VLT of 15-30% or higher.
Sunroof: This area typically absorbs a lot of heat, causing the car to get hot. Therefore, prioritize films with the highest heat rejection specifications.

Notes after applying automotive insulation films:

After applying automotive insulation films, there are a few things to keep in mind to maintain the longevity and performance of the film:

Within 24 hours after applying the insulation film:

Do not roll the windows up or down.
Do not attach accessories to the glass, such as dashboard cameras or sunshades.
Minimize touching, pressing, or cleaning the interior surface of the glass.

This is because the adhesive of the insulation film has not fully cured within 24 hours, and such actions may cause the film to shift, leading to damage.

During use:

Avoid using cleaning solutions containing strong detergents to clean the interior of the glass. Instead, use a soft, damp cloth to gently wipe the surface of the film.
Do not use sharp objects to press or scratch the film’s surface, nor should you place high-heat objects (like lighters) close to the film.
If any issues with the film are discovered, do not attempt to fix it yourself. Instead, take the car to the service center for professional warranty and repair.
