UV PROTECTION THAT WORKS
As summer temperatures rise, Personal Protective Equipment (PPE) becomes a critical line of defence for outdoor workers. While sunscreen often takes centre stage in sun protection, it is far from the only solution and for workers spending full shifts outdoors, it is not nearly enough on its own.
With skin cancer rates climbing and UV-protective product claims becoming increasingly misleading, it is more important than ever to understand how ultraviolet (UV) radiation affects the body, and how the right certified fabrics can offer powerful, lasting protection. At Concordia Textiles, we engineer fabrics that meet rigorous UV protection standards, because the right clothing does not just help workers stay comfortable now, it plays a vital role in preserving their long-term health.
UV radiation: The invisible risk
Unlike heat, UV radiation cannot be felt or seen, which is exactly why it is so often underestimated. UV exposure is highest during summer months, typically between noon and 4 p.m., but remains dangerous even on cloudy or cooler days. Workers in construction, agriculture, utilities, and logistics face this risk every shift.
There are three types of UV rays:
- UVA (320–400 nm): The most prevalent type. These rays penetrate deep into the skin and eyes and cause cumulative long-term damage, including premature ageing and increased cancer risk — even without visible sunburn.
- UVB (280–320 nm): Less abundant but more intense. Responsible for sunburn, and a primary driver of skin cancer development.
- UVC (100–280 nm): The most energetically dangerous form, but largely absorbed by the atmosphere. On earth, it is primarily encountered in occupational settings such as arc welding.
What makes clothing UV-protective?
Not all fabrics offer meaningful UV protection, even long-sleeved garments. Clothing that truly protects against UV radiation is independently tested and certified to meet specific performance standards.
The most widely referenced standard in Europe is EN 13758-2, which measures the Ultraviolet Protection Factor (UPF) of a garment. A higher UPF means less UV radiation reaches the skin. Other internationally recognised standards include UV STANDARD 801, AS/NZS 4399 (Australia/New Zealand), and AATCC TM 183 (USA).
Several physical factors influence a fabric's UV protection performance:
- Fabric density: Tightly woven or knitted constructions block more UV radiation than open or loose weaves.
- Colour: Darker and more saturated colours absorb more UV energy than pale or white shades.
- Fit: Loose-fitting garments maintain fabric density across the body surface and allow airflow. Tight fits stretch the weave, creating gaps that reduce protection.
- Condition: Worn, thinned, or damaged fabric loses protective performance. Regular inspection is essential.
- Wetness: Water-soaked fabric significantly compromises UV-blocking capability and should not be relied upon for protection.
Not all UV claims are created equal
The term “UV-protective” can be misleading when it is not supported by proper testing or certification. Many garments are promoted as “anti-UV” or suitable for sun protection, but this does not always mean they offer reliable ultraviolet protection.
Without a tested UPF rating or a recognised standard, it is difficult to know how well the fabric actually blocks UV rays. Some clothing may cover the skin, but still allow UV radiation to pass through. This can give the wearer a false sense of protection, especially during long periods of outdoor work.
Clear labeling and certified testing help prove the real level of ultraviolet protection a garment provides. They make it easier to choose clothing that offers dependable protection against UV rays, rather than relying only on marketing claims.
When evaluating UV-protective clothing, look for:
- CE certification according to EN 13758-2
- Transparent product information, not just icons or marketing slogans
- Evidence of third-party verification, not just manufacturer claims
But just how much protection does a UPF rating actually provide?
How much protection does a UPF rating actually provide?
The UPF number on a certified garment tells you the fraction of UV radiation that passes through the fabric to reach the skin. Here is what the rating scale means in practical terms:
UPF Rating | UV Blocked | UV Transmitted | Protection Category |
|---|---|---|---|
UPF 15–24 | ~93–96% | 7–4% | Good |
UPF 25–39 | ~96–97.5% | 4–2.5% | Very Good |
UPF 40–50 | ~97.5–98% | 2.5–2% | Excellent |
UPF 50+ | ≥98% | ≤2% | Excellent (Maximum) |
For outdoor professional applications, garments rated UPF 40 or above, classified as Excellent, are strongly recommended. A UPF 50+ garment, the highest category under EN 13758-2, blocks at least 98% of UV radiation, leaving no more than 2% to reach the skin. Sunscreen, by comparison, must be applied correctly, reapplied regularly, and covers only exposed skin, making certified UV-protective clothing a far more reliable line of defence for workers.
Preserving Performance Through Care
UV-protective garments require proper care to maintain their certified performance. Garments should be laundered according to the manufacturer's care instructions, as incorrect washing can degrade fabric construction and reduce UPF performance.
Garments should also be regularly inspected for signs of wear, thinning, stretching, pilling, or visible damage, any of which may compromise the fabric's protective function. When in doubt, replace. For PPE-grade applications, periodic re-testing of garments after extended use is recommended.
