YOUR BROCHURE REFERS TO CANCER COUNCIL WINDOW FILMS HAVING A UPF RATING OF 50+. I HAVE HEARD OF SPF BUT NOT UPF. WHAT’S THE DIFFERENCE
Sunscreens and lotions are usually measured using Sun Protection Factor (or SPF). Items such as shade sails, umbrellas and some clothing (and window films) can be marketed showing Ultraviolet Protection Factor (UPF). In order to market any product that displays a UPF rating, the product must have undergone testing with ARPANSA. Cancer Council is a premium window film that has been tested with a result of UPF 50+ which is the highest possible rating available.
