UV rays explained (short)

Hi Everyone!

When we professionals in the automotive area talk about Window Film, the topics covered are more focused on heat rejection and privacy, at other times we talk about physical safety of vehicle occupants. However, one of the most important points that can often go unnoticed is protection against UV rays. The action of UV rays is silent, but it can often go unnoticed while still causing damage to health.

Simply put, the spectrum of the sun’s rays is divided into zones, where each part affects the environment and things and people in different ways. There is the part of visible light, infrared and UV.

The most common form of UV radiation is sunlight, which produces three main types of UV rays:

UVA
UVB
UVC

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer. So, most of the UV rays you come in contact with are UVA with a small amount of UVB.

UV radiation is classified by wavelength. Wavelength describes the distance between the peaks in a series of waves.

UVB rays have a short wavelength that reaches the outer layer of your skin (the epidermis)
UVA rays have a longer wavelength that can penetrate the middle layer of your skin (the dermis)

Both UVA and UVB rays can cause damage to your skin. Sunburn is a sign of short-term overexposure, while premature aging and skin cancer are side effects of prolonged UV exposure.

This is why STEK Window Films are still needed to protect people (drivers, glazed buildings occupants, etc) againts all type of UV rays.

Window tint… what’s the point?

Window tints, window films, or energy control films—which is what we call them around the shop—are designed to control the amount of energy that is transmitted through your vehicle’s glass. Energy comes in the form of visible light, and the varying light wavelengths can have different damaging effects on the human body as well as your vehicle.

Tesla Model Y: The biggest game changer yet?

At a quick glance, the Tesla Model Y looks kind of like a Model 3 and a Model X had a baby. In fact, the Model Y actually shares about 75% of its components with the Model 3. This creates a lot of cost savings for Tesla and puts the Model Y—with 316 miles of range and a 0-60 time of 4.8 seconds—at a very fair price.
