Understanding your Windows SPF factor

The sun outputs two types of Ultra Violet (UV) rays which are responsible for damaging our skin, or simply said, giving us a sunburn.  UV rays cannot be seen.  UVA and UVB rays are responsible for premature skin aging, eye damage, and skin cancers.  A lot of research has been done and we have ways to prevent these damages.  However, when taking refuge and relaxing in your sunroom, we want to be able to sit under the sun.  That is why windows have an SPF protection factor.

SPF (Sun Protection Factor) is not an amount of protection per se.  Rather, it indicates how long it will take for the suns UVB rays to redden the skin with protection compared to how long it would take to redden the skin without protection.  To simplify, someone who is sitting behind a window with an SPF factor 60, will take 60 times longer to redden than a person sitting directly under the sun (not behind a window).  It is estimated that an SPF of 50 blocks up 98% of the suns UVB rays.

Having a higher SPF factor on your sunrooms windows means you can enjoy the suns shine for a longer period of time without having to worry about skin damage.  Your experts at Nature’s View Sunrooms are educated about each of their models and which offers the highest level of SPF protection in their windows.
