With the UK experiencing some much welcomed warmer weather over the last few weeks, it’s meant many have flooded outside to soak up some of the sun’s rays.
We’ve all had it drummed into us about the dangers of spending too much time in the sun and the importance of regularly applying sunscreen. But what about those unlucky workers who spend the sunny weekdays within the confines of an office? Or those that are at school? Are they immune from the sun if the only exposure they have is through a window?
Well, the answer is no.
Sunlight streaming through a window can still expose the skin to harmful rays which tan and freckle the skin, as ordinary glass does not filter out UVA rays. Meaning that someone sat next to a regular window (i.e. untreated with any special film) could get burnt if the sun was shining directly on them.
This is because the sun emits three types of ultraviolet rays: ultraviolet (UV) A, UVB, and UVC. But ordinary glass only blocks one: UVB. This also means that you don’t get the benefit of soaking up that vital vitamin D as this is produced by the body when the skin is hit by UVB rays.
Basically, it’s not going to do you any good and it could in fact do you harm, if you sit near a window on a sunny day.
So what’s the solution?
Instead of pulling down the shades and hiding from the sun for the duration of summer, UV reduction window film can be added to windows which cuts out 99.9% of UV light, preventing harmful rays from penetrating the glass.
This allows people to sit near the windows without fear of being harmed. It’s commonly used in office buildings and schools but is also ideal for use in shop fronts, historical buildings and museums. Because not only does it protect people from harmful rays, it protects interiors and objects from fading – another unfortunate by-product of UV rays.
The great thing about UV reduction window film is that once it is installed, you can’t even tell it is on the glass and it still provides optimum clarity.
