Sunroof Film & Auto Window Tint Film — Cooler Cabins, Clearer Views, Better Protection
By TECHLON · Shanghai, China · Est. 10+ Years in Automotive Film · Exported to 60+ Countries
If you have ever climbed into a parked car with a panoramic glass roof on a summer afternoon, you know the problem instantly: the cabin is an oven. A sunroof film — a dedicated line of our auto window tint film — rejects solar heat, blocks ultraviolet radiation, cuts glare and protects interiors, all without changing the view out of the roof. For distributors, auto chains and tint shops, it is also one of the fastest-growing add-on categories: every SUV with a glass roof is a candidate.
What Is Sunroof Film?
Sunroof film is a solar-control film engineered specifically for sunroof and panoramic glass-roof applications. It belongs to the same product family as window tint film — sharing the core functions of heat rejection, UV protection and glare control — but is specified for the extreme conditions a roof window faces: direct overhead sun, the largest glass area in many modern vehicles, and long hours of exposure.
The category covers nano-ceramic, sputter and UV400-grade films. At TECHLON, sunroof film (model prefix TT-RF) sits inside our auto window tint film range, which also includes nano-ceramic, UV400 skin care, sputter and chameleon films — one factory supplies every glass-coverage need.
Why Panoramic Glass Roofs Overheat — and What Tint Film Does
Automotive glass is transparent to most of the sun’s energy. A large sheet of glass sitting directly above passengers turns the cabin into a greenhouse, producing three problems: heat build-up that forces air-conditioning to work harder, UV exposure that reaches skin and fades upholstery, and glare that makes driving uncomfortable.
Sunroof film vs. no film — what changes
- Heat — IR rejection up to 99%, cabin stays cooler under direct sun
- UV — rejection up to 99.9%, protects passengers and prevents interior fading
- Glare — reduced 30%–90%, more comfortable and safer driving
- Privacy & style — even, deep shades from 5% to 70% VLT

Signal-Friendly: The EV and Sensor Question
Metallic films can block GPS, toll transponders, phone signals and even ADAS radar — a real problem in modern cars where antennas and sensors sit close to the glass. Our non-metallic nano-ceramic sunroof film delivers high heat rejection without the metal layer, so GPS, 5G, ETC and ADAS keep working normally. This makes it a natural fit for electric vehicles and any customer who values connected driving.
Built in Five Layers for Long-Term Performance
- Scratch-Resist Coating — a hard top coat that shrugs off squeegee marks and daily wear.
- Optical PET Base — high-clarity polyester that keeps the sky view haze-free and distortion-free.
- Nano-Ceramic Functional Core — ceramic nanoparticles that reject infrared (up to 99%) and ultraviolet (up to 99.9%).
- PSA Adhesive — automotive-grade pressure-sensitive adhesive for a strong bond and low-residue removal.
- Release Liner — a PET liner that protects the adhesive and is peeled off at installation.
