It's too hot for window film.

Thermal insulation film is actually another name or alias of explosion-proof film (is it necessary for automobile film to lose its thermal insulation? ) Explosion-proof film (originally referred to as solar film) functions: 1, heat insulation and cooling, 2, ultraviolet protection, 3, anti-cracking and fading of automobile accessories, 4, anti-glare, 5, personal safety protection (avoiding glass bursting and personal injury, explosion-proof film safety base has very good impact resistance and tear resistance) 6, beautiful and environmentally friendly. The most important thing is to choose the right brand and choose the right one. At present, there are too many fake films on the market, especially a series of Ray-Ban and 3M. I suggest that you don't go to a roadside shop to buy it. It is best to go to an authorized store of a local professional brand to buy it. Your car personally recommends brands such as 3M or Gu Wei (authentic Gu Wei has good heat insulation).
