The difference between the two is:
1. Different sun protection and heat insulation effects
Metal film technology has disadvantages, such as easy shielding of the mobile phone. Signals and poor heat dissipation, while ceramic film It is not easy to block mobile phone signals and has good heat dissipation. Thus, automotive metal insulating films are gradually being replaced by ceramic films.
2. Different Signal Transmission Rates
Another key difference between metal films and ceramic films is the signal blocking rate. Many car owners encounter unfamiliar roads when driving and need to use in-car navigation and mobile phones, but travel is often affected by poor signals. When one encounters this situation, it is sometimes due to the operationmobile phone misser, but sometimes it is because the heat insulation film of the car affects the signal passage.
3. Different Total Solar Energy Rejection Rates (TSER)
The higher the total solar energy rejection rate index, the better the thermal insulation performance. The total solar energy blocking rate index of the metal insulating film is lower, and the total solar energy blocking rate of the ceramic insulating film is higher. If you are a car owner concerned about heat insulation, sun protection effect and 100% smooth signal, you should choose the mainstream ceramic film.
4. Different internal reflective effects
Ceramic membranes are durable, not easily oxidized, have a long service life, are easy to construct, and are not internally reflective. Metallic films are more susceptible to oxidation and rinternal reflection.

Which is better, Zunyi 70 or Houyi 70
KOOL Weigu, global Brand of Eastman Chemical, the largest manufacturer of automotive films and member of the World Window Film Association, it is firmly in the high-end automotive film camp with its magnetron sputtering insulating film.
Main model:
Front gear
Weigu VP70 has a total solar energy barrier of 55%, light transmittance of 71% and 4 mil thickness;
VK70 total solar energy barrier is 55%, light transmittance is 71%, thickness is 1.5 mil;
Side rear protection
VP40, VP28, VK25, of 46% and the thickness is 4 mil;
Weigu VP28, the total solar energy blocking rate is 56%, light transmittance 29%, thickness 4 mil;< /p>
VK25, the total rejection rate of solar energy is 68%, light transmittance 28%, thickness 2 mil;
Veigu X15, the total rejection rate of solar energy is 67%, light transmittance is 16%, thickness is 1.5 mil;
Weigu K15, the total blocking rate of solar energy is 60%, light transmittance is 18%, thickness is 1.5 mil;
Weigu K35, total solar energy blocking rate is 51% , the light transmittance is 35% and the thickness is 1.5 mil;
Weigu H25/T3, the total solar energy blocking rate is 52.5% and the transmission of thelight is 24.8%;
Weigu G20/T2, the total solar energy blocking rate is 65%, and the light transmittance is 17.%;
VP This is Weigu safety protective film series, which is a series of Weigu products focused on protection and also rich in thermal insulation. In terms of automotive glass films, those with a thickness of more than 3 mil are generally called safety films, and the VAG VP series has reached 4 mil.
Hou Yi 70.
Whether it is thermal insulation, light transmission or quality assurance, Houyi series is obviously better than the Zunyi series in 4S stores.
