Coolverre, which blocks ultraviolet rays (UV) and infrared rays (IR), is used as automotive glass that is friendly to both the driver and the environment. We developed this product in response to a request from customers who want more comfort in driving. By blocking infrared rays, which cause a thermal effect, Coolverre halves the time required for an air conditioner to decrease the in-vehicle temperature from 45°C to 25°C. The glass thus helps improve cooling efficiency, which in turn reduces CO2 emissions from the vehicle*1. As its biggest feature, Coolverre substantially blocks middle infrared rays, which mostly cause the skin to sense frizzling heat. As a result, it feels cooler inside the vehicle than the actual outside temperature, which in turn leads to a reduction in energy consumption by air conditioning. In addition, the product, incorporating Asahi Glass's unique technology, blocks ultraviolet rays, which are known to cause blotches and freckles, while allowing radio waves used for the ETC system*2 and cell phones to enter the vehicle. Coolverre, developed using Asahi Glass's technological capabilities, is indeed friendly to people and the environment.

Comparison between ordinary windshield and Coolverre

Effects of Coolverre Comparison of average in-vehicle temperatures (measured inside a vehicle parked in a space facing south in the summer) Coolverre prevents the in-vehicle temperature and the temperature of interior materials from increasing, thereby improving the cooling efficiency of the air conditioner.
