Scientist and medical experts have determined that ultraviolet (UV) radiation causes sunburn, skin aging, and skin cancer. To help individuals understand and respond to the potential hazard from UV, the UV Index was introduced in a number of countries in 1995 & 1996. In the U.S., it is published on a daily basis and provides an estimate of the maximum potential hazard from UV for the next day.

The Ultraviolet Protection Factor (or “UPF”) rating system measures the UV protection provided by fabric. It is very similar to the SPF rating system used for sunscreens.
A garment with a UPF of 50 only allows 1/50th of the UV radiation falling on the surface of the garment to pass through it. In other words, it blocks 49/50ths or 98% of the UV radiation.
All Protect-a-Bub sunshades rate UPF 50+, which is the highest possible rating.
|Protection Category||UPF Ratings||% UVR Blocked|
|Excellent Protection||40, 45, 50||More than 97.5|
|Very Good Protection||25, 30, 35||95.9 to 97.4|
|Good Protection||15, 20||93.3 to 95.8|
|Insufficient Protection||2, 10||50-90|
There are a number of factors that affect the level of ultraviolet protection provided by a fabric and the UPF rating.
In order of importance these are:
At Protect-a-Bub, we have an accredited, independent testing facility test the UV protection level of every batch of material we produce for our sunshades.
