When shopping for sun protection, you may come across different ratings like UPF (Ultraviolet Protection Factor) and UVE (Ultraviolet Effectiveness), each designed to measure UV-blocking abilities. While UPF is most commonly found in sun-protective clothing, UVE ratings are applied to various non-clothing materials, like outdoor shade products. Understanding the difference between these two ratings can help you make more informed choices about sun protection, whether it’s for yourself or your environment.

What Does UVE 95 Mean?

UVE stands for Ultraviolet Effectiveness and indicates the percentage of UV radiation blocked by a shade material. A UVE rating of 95, for instance, means that the material blocks 95% of ultraviolet rays, allowing only 5% to pass through.

Where UVE Is Used

Outdoor Shade Products: The Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) introduced UVE ratings for shade products like umbrellas, tents, cabanas, shade sails, and awnings. These ratings help consumers assess the level of UV protection provided by shade structures, which can be essential for outdoor gatherings and extended time in the sun. However, a high UVE rating should not be relied upon as the only form of UV protection. Complementing shade products with UPF clothing and sunscreen ensures comprehensive sun safety.

What Does UPF 50 Mean?

UPF, or Ultraviolet Protection Factor, is a rating system primarily used for fabrics to indicate their ability to block UV radiation from reaching the skin. Unlike UVE, which may apply to a variety of materials, UPF specifically measures the UV-blocking effectiveness of fabrics and is commonly found on sun-protective clothing and accessories.

A UPF rating of 50 means that only 1/50th of the sun’s UV rays can pass through the fabric, effectively blocking 98% of ultraviolet radiation. UPF covers both UVA and UVB rays, offering full-spectrum protection for exposed skin.

Rating Scale

UPF 15-20: Provides good protection, blocking 93-95% of UV rays.
UPF 25-35: Offers very good protection, blocking 96-97% of UV rays.
UPF 40-50+: Delivers excellent protection, blocking 97-98% of UV rays.

Where UPF Is Used

UPF ratings are applied to clothing and accessories like hats and sleeves. They indicate the fabric’s effectiveness at shielding the skin from UV radiation, making UPF-rated items particularly valuable for prolonged outdoor activities.

What Does the Plus (+) Mean in UVE 95+ and UPF 50+?

The "+" in UVE 95+ and UPF 50+ indicates that the material or fabric exceeds the minimum threshold for that rating. For example, UPF 50+ means the fabric blocks at least 98% of UV radiation, but in many cases, it may block even more. Similarly, UVE 95+ means that the material blocks at least 95% of UV rays, offering a higher level of protection than a simple UVE 95 rating. The "+" provides additional assurance that the product delivers superior UV-blocking performance, making it a reliable choice for sun protection.

Key Differences Between UVE vs. UPF

While UVE and UPF ratings both offer information on UV-blocking effectiveness, they differ in what they measure and the types of products they apply to:

Material Type

UVE Ratings: Used for non-fabric items like outdoor shade products such as tents and umbrellas.
UPF Ratings: Exclusively used for fabrics and garments, providing direct sun protection for the skin.

Protection Against UV Rays

UVE: Often indicates the general ability to block UV radiation without specifying the types of rays (UVA or UVB). In most cases, a UVE rating refers to the overall percentage of UV light blocked.
UPF: Measures both UVA and UVB protection, ensuring that the fabric shields the skin from both aging and burning rays.

Standardization and Testing

UVE: Developed for materials that don’t involve fabric, with ARPANSA’s recent addition of UVE ratings for outdoor shade products. UVE ratings provide assurance of UV protection but are tailored for settings beyond direct skin contact.
UPF: Tested specifically for clothing to ensure consistent, skin-friendly protection against the full UV spectrum.

Why Understanding UVE and UPF Matters

Both UVE and UPF offer valuable information for different aspects of sun protection. Here’s how each can be applied:

Direct Skin Protection: UPF-rated clothing and accessories are designed to shield your skin directly from UV rays, making them essential for outdoor activities where sun exposure is prolonged. With UPF clothing, you can ensure that your skin remains protected without the need to constantly reapply sunscreen.
Shade Protection: UVE ratings are particularly valuable for outdoor shade structures, offering UV protection in areas requiring transparency or partial coverage. Products like UVE-rated tents and umbrellas provide reliable sun protection for gathering spaces.
Whole-Environment Sun Protection: Together, UVE and UPF ratings allow for a comprehensive approach to sun safety. By combining UPF clothing for personal protection and UVE-rated shade structures for environmental coverage, you can create a layered approach to UV protection.

The Bottom Line: Different Ratings for Different Needs

While both UVE and UPF ratings provide essential information about UV protection, they serve distinct purposes. UPF 50-rated clothing is specifically designed to shield your skin from harmful UVA and UVB rays, delivering consistent, all-day protection during outdoor activities. In contrast, UVE ratings, such as UVE 95, are applied to materials like shade structures, measuring their ability to block UV radiation and create safer shaded spaces.

By understanding these ratings, you can make informed decisions about your sun protection needs. Whether you're safeguarding your skin or creating UV-protected environments, choosing products with the appropriate UVE or UPF rating ensures you can enjoy the outdoors confidently while minimizing harmful UV exposure.
