The Filigree lining range has a number of unique attributed and benefits. One of them is its UPF rating. However, what does it mean to have our lining UPF rated? Join us as we explore this benefit. 

What is a UPF fabric rating?


Ultraviolet Protection Factor (UPF) indicates how much UV radiation (both UVB and UVA) a fabric allows to reach your skin. For example, a fabric with a UPF rating 50+ blocks 98 percent of the sun’s rays and allows two percent (1/50th) to penetrate, thus reducing your exposure risk significantly.

Some of the factors that contribute to the UPF rating of fabrics are;

• Composition of yarns (cotton, polyester, etc.)
• Tightness of the weave or knit (tighter improves the rating)
• Colour (darker colours are generally better)
• Stretch (more stretch lowers the rating)
• Moisture (many fabrics have lower ratings when wet)
• Finishing (fabrics are treated with UV absorbing chemicals)




Part of the solar radiation spectrum is shown in the figure below. In general, there is almost as much UVR scattered from the sky as there is direct from the sun. Hence staying out of the direct sun does not eliminate the hazard and still means your curtains, your furniture and you can suffer long term damage from scattered UVR. 





What is the difference between UPF and SPF?

 SPF is a standard used to measure the effectiveness of sunscreens. It provides only UVB protection and prolongs your protection 15 times the time it takes to burn. UPF on the other hand, is a standard used to measure the effectiveness of sun protective fabrics. It provides both UVA and UVB protection. A UPF of 50+ blocks our 49/50 (98%). Not every fabric provider offers this standard which is why Filigree Linings are your best choice at ensuring the best environment for your family. 


Which of our lining products are UPF tested?

Did you know that all our coated lining ranges are UPF tested? We test to the highest UPF standard meaning all of our lining products meet a UPF50+ and UPF30+ rating.
