Do Tinted Windows Block UV Rays?

As a country that experiences some of the harshest ultraviolet rays on earth, Australia is no stranger to the scourge of sun damage. Owing to Australia’s proximity to the South Pole’s seasonal ozone hole, Australians have to slather on the SPF to avoid permanent skin damage from sun exposure. The thing is, it’s not only our skin that takes a beating from the sun. Everything the sun touches is affected by it; the sun bleaches fabric and eats into the interiors of your car, home, or workplace. For this reason, tinted windows are essential in Australia. Tinted windows block UV rays and reduce damage to our skin, building interiors, and car interiors.

What Are UV Rays?

Ultraviolet rays, also known as UV rays, are a form of electromagnetic radiation which is invisible to humans. UV rays are produced by the sun, electric arcs, tanning lamps, and black lights. Of course, it’s the sun we are most in contact with, it’s wonderful and warming, but also inescapable. Ultraviolet light is the reason our skin burns in the sun, and exposed surfaces fade and deteriorate over time. We are often oblivious to the damage that UV rays do because it happens gradually. This is why scientists developed window tinting; to block UV rays and protect us from the damaging effects of the sun. Not all ultraviolet light is the same, though.

Types of ultraviolet rays:

  • UVA is a long wave ultraviolet radiation which is not absorbed by our ozone layer.
  • UVB is a medium wave ultraviolet radiation, most of which is absorbed by the ozone layer.
  • UVC is a short wave ultraviolet radiation which is completely absorbed by the ozone layer.

How Does Window Tinting Block UV Rays?

While ultraviolet radiation levels are typically much lower inside a vehicle than in full sunlight, UV rays can still penetrate the glass. Laminated glass used for windscreens and tempered glass, which is usually used for side and rear windows, both block UVB rays. UVA rays, however, are more substantially blocked by laminated glass. Laminated glass blocks about 98% of UVA radiation. To prevent these harmful UVA rays from penetrating the tempered glass, one can apply a clear or tinted film, provided it is specified as a UVA and UVB blocking tint.

A good quality window tint will block over 99% of the total ultraviolet radiation. This tinting is so effective that it has become commonplace in not only cars but also on the windows of buildings and homes. Window tint blocks UV rays by controlling the level of heat and light which pass through them.

If your car windows are not already tinted, you should consider investing in a good quality UV blocking tint. Tinted windows will help keep your car cool, preserve the finish of your interior and the colour of your seat fabric, and most importantly, minimise irreversible sun damage to your skin!
