On the heat insulation and sun protection effects of the Li L6 glass

We recently acquired the Li L6, a family five-seater SUV, and today we would like to discuss a topic closely related to every family's vehicle usage, particularly focusing on the heat insulation and sun protection effects of the Li L6's glass.

While performance parameters of the vehicle may not be deeply felt by every passenger, the heat insulation inside the car is something everyone can intuitively experience.

Before delving into the heat insulation performance of the Li L6, let’s first take a look at its glass configuration. The front and rear windshields of the Li L6 are supplied by Fuyao Glass, while the four side windows use products from Wuhu Xinyi Glass.

To further understand the heat insulation performance of the glass, we used a 250W infrared emission device to test the infrared blocking effect of the vehicle's glass.

Why test infrared heat?

This is because infrared light accounts for the largest proportion of solar heat. By testing infrared heat, we can more accurately evaluate the heat insulation performance of the glass.

(In the heat distribution of sunlight, ultraviolet light accounts for 3%, visible light for 44%, and infrared light for 53%.)

Based on our actual tests, the heat insulation performance of the Li L6's glass is as follows:

In terms of the sunroof design, the Li L6 differs from the L7, L8, and L9. It is equipped with a crossbeam-free panoramic sunroof, with an official light transmission area of 1.26 square meters. The sunroof glass effectively blocks ultraviolet light.

According to our infrared heat test data, the heat insulation effect of the sunroof glass is quite good. Additionally, the equipped electric sunshade provides extra physical blocking, almost completely blocking heat. Therefore, we recommend that no additional heat insulation film or sunroof ice armor is needed for the sunroof.

The rear side windows use dark-tinted double-layer privacy glass with a light transmittance of less than 30%. This design allows the glass to block most visible light and infrared heat, so we recommend no additional film is applied. If film is indeed necessary, it is advised to choose a film with higher light transmittance to avoid affecting the rear passengers' view.

For the front windshield, possibly due to cost considerations, the Li L6 does not adopt the double-layer silver-coated glass used in other models of the L series. As a result, its heat insulation effect is slightly inferior to the other three models in the L series. However, compared to other vehicles not using silver-coated glass, its performance is still commendable.
