How to Choose the Right Car Windshield?

[LeColin]

Car windshield selection criteria are as follows: 1. Privacy: For those who prioritize privacy, models with lower light transmittance can be chosen. The lowest available on the market is 5%, making it nearly impossible to see inside even when pressed against the window. 2. Heat Insulation: To enhance heat insulation performance, opt for models with higher infrared blocking rates and overall heat insulation rates. Typically, market offerings achieve around 60-70% heat insulation. However, even the best car window films cannot completely prevent interior temperature rise; they can only mitigate or slow down the rate of temperature increase.
