Information
on the resistance of Alnet's UV Ultrablock Shade Cloth: SPF
- What does it mean?SPF
stands for sun protection factor. The higher the SPF number, the more protection
it should afford from exposure to UV rays. The SPF number gives one some sense
of how long one can stay in the sun without getting sunburned. It
is calculated as follows:  | Burn
time without sunscreen = 10 minutes |
| Burn
time with sunscreen SPF 15 = 10 min. x 15 = 150 min. (2 ½ hours) |
