When you go to the beach and sunbathe to get a tan, you will likely feel a bit fragile and burnt after spending hours under the sun. A better and more sensible option is to catch the rays of the sun from the windows. The glass pane will absorb majority of the sun’s harmful UVB rays but less than 40% of its UVA. UVA is ultraviolet radiation that is between 400 and 320nm wavelength.
Most panes of glass absorb about 97% of the sun’s UVB rays or the ones that cause skin burns or certain types of skin cancers. UVB is strongest from 10AM to 4PM but will not significantly penetrate glass to cause harm to your skin. Glass only absorbs 37% of UVA rays but it is less harmful radiation because of the longer wavelength.
Sitting behind a glass pane is equivalent to applying SPF30 sunscreen which means you can be tanned, freckled and even burnt if you stay too long on the sunny spot. Meanwhile, the windscreen of the car although made from glass is different from the glass used in your windows. The car’s windscreen has a plastic layer in between two layers of glass to block 100% of UVB rays and 80% of UVA rays. It is very unlikely that you will get a tan from inside the car during a long journey because of the protection provided by the glass windscreen.
On the other hand, even if you are not interested in getting a tan, you still need sunlight for Vitamin D. Vitamin D will help regulate the amounts of calcium and phosphate in the body for healthy bones, teeth and muscles. If you are stuck in the office during the day, how can get Vitamin D? UVB rays are blocked by the windows which mean you have to be outdoors from time to time to ensure you do not become Vitamin D deficient.
Glass is often installed on the windows for aesthetics and protection against the weather. If you need replacement for glass, there is a glass cut to size near me while you wait. The cutting services provided will ensure that glass is custom fit for the window.
