Most of the insulation films on the market now only advertise their products with high infrared ray rate, but is it really a good thermal insulation film? wrong.

First we need to understand the source of heat in the sun.

VL visible light 44%

UV UV 3 %

IR infrared 53%

When the sun shines on our skin, our skin feels hot because the infrared rays penetrate but change from light energy to heat.

Therefore, if the heat-insulating film is only high in infrared ray rejection, according to the law of material heat indestruction, the heat radiation of the sun does not penetrate. Where is the heat going? This is a very simple logic. Ask the above question, right! The heat can't be gone, right! Is the heat absorbed by the glass? Then you touch the glass, God! How is the glass hotter than the one that is not attached?

​

If the radiant heat of the sun is penetrating and directly into the car, the chair, the dashboard and the steering wheel will be very hot, and the glass will not be hot, because the heat has penetrated, so it is not left on the glass, but if The radiant heat is absorbed by the insulation film, the heat does not penetrate, and it is not injected into the room, so the chair, the instrument panel and the steering wheel will not be hot, but the glass will be hot, because most of the common commercially available insulation films The infrared rays are adsorbed on the glass. If the glass absorbs the heat radiation, it will naturally be very hot. You can touch the glass with your hand to know that the original heat source is all on the glass, and even the hot hand does not dare to touch. In one second, this is an absorption type of heat insulation. This is the heat absorbing film. The heat on the glass also generates secondary radiation. More than 40% of the glass heat enters the car through the air inside the car.

​

How can we really insulate? That is to let the infrared reflection instead of absorption, Huten's insulation film will reflect most of the heat radiation, not absorbed on the glass, so the glass will not be so hot, and Infrared rays can not enter the car, allowing visible light to pass through, but reflecting the infrared rays without leaving them on the glass. This is the most effective thermal insulation film in the world.

 

It is generally believed that if the thermal insulation film is expensive, it is expensive, and vice versa is cheap. In fact, it is not completely correct. It must be said that a top-quality thermal insulation film must meet the following conditions:

1. High-reflection insulation technology (rare precious metal multilayer magnetron sputtering plus nano ceramics)

2. High transparency, high temperature resistance, good durability, no foaming, no wave pattern

3. Highly clear PET film does not affect driving sight

4. Does not affect smart tag and GPS

5. The car is parked in the sun, the heat is far slower than the general insulation film, once the car is opened, the heat is fast.

6. Protect the skin and the interior of the car, and effectively reduce the noise generated inside the car.
