PREMIUM AUTOMOTIVE WINDOW FILM - GENUINE PRODUCTS AT SPECIAL 2025 PRICES

Automotive window film has become increasingly popular among car owners across Vietnam. However, not everyone fully understands what window film really is, which type is best, or the latest pricing updates. That is why, in the article below, LLumar Vietnam will summarize and share useful information about automotive window films, along with updated pricing for installation. Let's explore together.

1. What is automotive window film?

Automotive window film is a thin polyester film coated with multiple layers of metal or other materials, such as ceramic, carbon, etc., using modern sputtering technology. The film is applied to the inner surface of car windows, primarily to block the sun and heat. It offers several benefits:

• Lower cabin temperature, ensuring comfort and coolness.
• Block UV rays, protecting skin health and preventing interior damage caused by ultraviolet light.
• Save fuel by reducing air-conditioning load.
• Enhance safety as the film holds shattered glass in place during impact.
• Enhance aesthetic appeal and privacy.

Thanks to these practical benefits, automotive window film has become increasingly popular and is now considered an essential accessory for car owners.

2. Practical benefits of automotive window film

The car window, directly exposed to sunlight, is the main cause of rising cabin temperature, affecting both passengers and the vehicle's interior. Window film solves this problem almost completely and offers additional benefits such as:

2.1 UV protection

Automotive window films can block up to 95% of harmful UV rays, helping protect passengers' skin and eyes while preventing vehicle interiors from premature wear and tear.

2.2. Heat reduction

Most window films today can reduce heat gain up to 65%, helping balance cabin temperature. This creates a cooler, more comfortable driving experience, reduces the need for air conditioning, and saves fuel.

2.3. Glare reduction

Window films significantly reduce glare, especially when driving against the sun or facing headlights at night. This improves visibility and ensures safer driving.

2.4. Superior interior protection

By blocking solar radiation, window film preserves the durability and appearance of your vehicle's interior. It prevents dashboards, leather seats, and steering wheels from fading, cracking, or warping.

2.5. Privacy and aesthetics

High-quality films feature strong reflective properties that block outside visibility, increasing privacy and enhancing the car's exterior appearance.

3. How to choose high-quality automotive window film

The market offers a wide range of films. To choose the right one for your vehicle, you should pay attention to the following performance indicators:

• TSER (Total Solar Energy Rejected): Indicates total heat rejection. The higher the TSER, the better the heat reduction.
• UVR (UV Rejection): The percentage of UV rays blocked. Choose films with UVR of 99% or higher.
• VLT (Visible Light Transmission): The amount of light passing through. Higher VLT means clearer visibility but lower heat rejection. Choose VLT according to personal needs and legal regulations.
• IRR (Infrared Rejection): Measures resistance to infrared rays, the main cause of heat buildup. A higher IRR ensures better cooling performance.
• VLR (Visible Light Reflectance): Indicates how much light is reflected. While high VLR improves heat rejection, it may cause glare for other drivers at night. Balance between heat reduction and driving safety.
• Glare reduction: Ensures comfortable visibility, reduces eye strain, and enhances safety while driving.

5. Standard installation process for automotive window film

To maximize film performance and longevity, correct installation is essential. Below are the 2 most common methods:

Automotive window film installation processes

5.1. Professional installation at workshops

Step 1: Vehicle inspection and film pre-shaping

Since automotive film expands when heated, it can technically be applied inside or outside the glass. However, to ensure durability, technicians always install it on the interior surface. Before starting, the vehicle is inspected. The film is measured and roughly cut to size, placed on the glass, heat-shaped to match curvature, and excess material trimmed precisely.

Step 2: Glass cleaning

For vehicles with old film: The existing film is removed with blades or cleaning agents. Steel wool may be used on the rear window with care to protect defroster lines, followed by plastic squeegees to remove residual adhesive.

For new installations:

• Remove dust with a microfiber cloth or soft brush.
• Clean stubborn stains (oil, tar, insect marks) using glass cleaner or diluted dish soap with warm water. A razor scraper or sponge may be used if needed.
• Dry thoroughly with a clean microfiber cloth.
• Re-check to ensure the surface is spotless and lint-free.

Step 3: Positioning the film

The glass is sprayed with slip solution. The protective liner is peeled back while spraying the solution to prevent static. The film is carefully placed on the window and aligned with the edges.

Step 4: Squeegeeing and bonding

Solution is sprayed on the film surface, then a squeegee is used with firm, even strokes to expel trapped water and air bubbles. This step is critical to long-term adhesion and visual quality.

Step 5: Final inspection and handover

The glass is wiped clean, both sides inspected, and any imperfections corrected immediately. In case of serious defects, the film is reapplied. Finally, customers are advised not to lower the windows for at least 48 hours to allow full curing.

5.2 DIY installation at home

• Step 1: Clean all windows thoroughly to ensure strong adhesion and a neat finish.
• Step 2: Mix mild soap with water in a spray bottle to create a slip solution.
• Step 3: Spray solution on the window, peel half the liner, apply and align the film, then peel and apply the rest.
• Step 4: Use a squeegee or plastic card to push out air bubbles.
• Step 5: Use a heat gun or hair dryer to gently warm the edges so the film conforms to the glass curves. Re-check and smooth out any remaining bubbles.

6. Conclusion

A proper window film installation not only enhances comfort and privacy but also protects passengers' health and preserves the vehicle's interior over time. For genuine LLumar automotive films at competitive prices or free consultation on installation, please contact LLumar Vietnam at our Hotline: +84 909.371.246
