Does car glass block UV rays?
2 Answers
Currently, many car models on the market have windshields that provide UV protection. Here is relevant information: 1. UV-blocking glass function: Filters sunlight, reduces skin damage caused by UV rays, and has the ability to block UV transmission. It helps maintain interior insulation, ensures air conditioning efficiency, and minimizes the impact of external temperature or sunlight on the cabin temperature. 2. UV-blocking and heat-insulating glass: This is a special type of glass where metal oxides are incorporated into ordinary silicate glass under strict smelting conditions, giving the glass special properties to absorb UV rays and block heat. Alternatively, post-coating techniques can be applied to ordinary glass to achieve UV protection and heat insulation. Although UV rays have the ability to kill bacteria.
I've been driving for many years. I used to think that sunlight coming through the windshield would often make my skin red and hot, but later I learned that most car glass can actually block UV rays. Windshields are usually double-layered with a special film in between, which can block over 95% of both UVB and UVA, so my skin suffers less, and the interior doesn't fade or age as quickly. Side and rear windows might offer slightly less protection, but they still have some treatment. Now, my car's glass comes with this built-in protection, making the interior much cooler in the summer without needing extra tinting—saving money and hassle. I also try to avoid driving during the peak midday sun and use the sun visor for extra comfort and peace of mind.
