All our awning fabrics offer a UV protection level of at least 90%. This means that you will feel safe enjoying the summer under the shelter of a Lewens awning. The UPF value of the fabric indicates how much UV solar radiation is absorbed by the material and how great its shielding effect is.
UV radiation
The solar radiation reaching the Earth's surface is invisible. While UVA radiation is less damaging to the skin and is responsible for tanning, UVB radiation leads to sunburn and is a cause of cancer. To prevent irreparable skin damage, good screening and preventive precautions are required.
The filtering capacity of awning fabrics depends on their weight, thickness and colour. The protection factor of our awning fabrics is indicated using the internationally recognised UPF (Ultraviolet Protection Factor) value for sun screening textiles (calculated according to AS/NZS 4399:1996). All our awning fabrics offer a UV protection level of at least 90%.
UPF valuet
The UPF value indicates how much UV solar radiation the fabric absorbs (UVA and UVB):
 |
UPF 15 - 24 | good UV protection (93.3% - 95.9% absorption) |
 |
UPF 25 - 39 | very good UV protection (96.0% - 97.4% absorption) |
 |
UPF 40 - 50, 50+ | excellent UV protection (> 97,5 % absorption) |
Example:
The UPF value 30 means that 29/30 of the rays are blocked out or absorbed and only 1/30 of the UV radiation penetrates the fabric. The fabric thus offers a protection level of 97%.
