How do you make glass UV protected?

What is the difference between UV A UV B and UV C light?

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.

Does sunlight through a window count as direct sunlight?

Is light through a window considered direct sunlight? It depends. If the sun’s rays directly hit the plant – such as through a south-facing window – this is considered direct sunlight. If the sun is bright but the rays don’t directly hit the plant, this is considered indirect light.

Does UV glass prevent fading?

The most harmful radiation in sunlight are the ultraviolet (UV) rays, which are the most energetic and thus most likely to break chemical bonds, leading to fading and degradation. Glass blocks all UV radiation below 300 nm, but transmits UV from 300-380 nm. Coatings on glass can reduce the UV transmitted by up to 75%.
