Skin-friendly, UV and IR cut glass "Coolverre"

You can imagine how hot the inside of a car is in summer. Even if you are using the air-conditioner, sunlight falls on you through the wide windshield as if it pierces your skin. You must have been annoyed by that unmerciful sunlight. Summer sunlight also makes you feel like your skin is being frizzled. This feeling of being frizzled increases discomfort while you are in the car. We have developed the automotive glass "Coolverre" to drive that discomfort away and enable you to experience comfortable driving conditions. This glass attracts attention as a glass that is friendly to women skin. There is a reason, of course.

What's UV or IR?

The sunlight can be categorized into visible light, ultraviolet rays (UV), and infrared rays (IR). While you can see visible light, UV and IR are invisible. UV and IR are dominant among the sunlight in harming human skin. Many goods that protect skin against UV are already available. You must have repeatedly seen or heard the word "UV cut" in sunglasses or cosmetics. Especially, strong UV in summer can easily harm human skin. It may cause sunburn, liver spots, wrinkles, and even skin cancer. Cutting UV is the prime principle to protect your precious skin. IR is converted to heat by being absorbed into many things. When your skin is exposed to IR, you feel like your skin is being frizzled by the effect of the mid-infrared radiation. By cutting IR, you can relieve the feeling of being frizzled and improve the efficiency of the air-conditioner. The improved efficiency can also contribute to higher mileage of your car.

The advantages of Coolverre

Coolverre blocks UV and IR and allows visible light to pass through. Why can Coolverre function in that way? The key is its unique "laminated glass" structure. Coolverre consists of three layers: the glass facing outside, the glass facing inside, and the thin intermediate film between the two glass surfaces. The intermediate film contains IR cut chemicals that we have originally developed. This IR cut chemicals has excellent properties to absorb not only the heat rays of IR but also UV effectively. These special absorbent particles are contained in the intermediate film to make it possible to absorb UV and IR and allow only visible light. With conventional automotive glass, you will have the feeling of being frizzled only in 30 seconds after your skin is exposed to sunlight. With Coolverre, however, you will not have that feeling up to around one minute. In general, when you are driving a car, you can escape into a shade area within one minute. If your car has a windshield of Coolverre, you can enjoy driving even in a hot mid-summer day without having the feeling of being frizzled. Many Japanese cars have already used Coolverre as the automotive glass that supports comfortable driving. By developing products that contribute to comfort, we will be supporting pleasure of driving.
