Is the heat insulation film applied inside or outside the car?

[ColtonAnn]

Inside the car. The functions of automotive heat insulation film are as follows: 1. Thermal insulation: Blocks infrared radiation and absorbs a small amount of heat conduction, achieving relative insulation and indirectly reducing air conditioning load for energy saving. 2. UV blocking: Most mid-to-high-end heat insulation films on the market can block over 98% of UV rays, protecting the skin of drivers and passengers from UV damage, and more importantly, delaying premature fading, aging, and cracking of car interior items and leather. 3. Explosion-proof: High-quality automotive heat insulation films use special materials for the adhesive and plastic substrate, providing excellent adhesion and impact resistance, significantly improving safety by preventing theft, robbery, and collisions.
