Outdoor furniture and summer days are a match made in heaven. The feeling of sun warming your skin as you sit poolside is what summertime memories are made of. But much like how you would use sunscreen to protect your skin from the damaging effects of UV rays, your furniture should be equipped with its own version of SPF.


When it comes to DIY projects, the fabric you use in your outdoor living space needs protection from the sun. UV damage can cause your once-vivid fabric to degrade and break down faster, taking a toll on its durability and shortening its useful life.


So, how do you find truly fade-resistant upholstery fabric? Let’s take a look at what goes into UV-resistant fabric and how you can ensure that your investment stays gorgeous and strong, even after several summers’ worth of rays.

How Is Sun / Fade Resistant Defined?

A sun-resistant fabric is one that has been treated to withstand UV rays, which account for approximately 10% of the sun’s light. UV stands for “ultraviolet,” which is a form of light wave or radiation. UV rays have a shorter wavelength than visible light and a longer wavelength than X-rays. This wavelength makes them particularly good at penetrating through objects, which is how they can cause damage.


Prolonged exposure to UV rays can cause materials to break down. In the case of outdoor fabric, UV rays can cause a chemical reaction with the dyes in the fabric or with the man-made plastic (polymer) yarns of the fabric itself. The breakdown of the dye or fiber is what causes fading. This process is known as “photo degradation.”


The term “sunproof fabrics” can be somewhat misleading. There is no fabric in the world (even those engineered for NASA!) that can withstand all UV rays for an indefinite amount of time. So, how do you measure how sun resistant a fabric really is? Some damage and fading will inevitably occur over time, but a sun-resistant fabric should be able to resist significant fading for the expected lifetime of the furniture.

The Phifer Difference: How We Test Our Sun-Resistant Fabrics

For an objective explanation of a fabric’s level of sun resistance, we can look at independent industry standards. The most common measure of sun resistance is “hours to fade.” Using this standard, fabrics are tested in a lab using special UV lights. This process simulates years of sun exposure in a matter of days or weeks. The fabric is observed in experiments that measure how long a sample takes to show a noticeable color change.


For woven upholstery fabric, the industry standard for a sun-resistant fabric for interior application is at least 40 hours with no color change. Phifer’s process for testing our exterior Designed Fabrics for sun resistance involves exposing our fabrics to a UV source, elevated temperatures and moisture -- all of the elements they’ll come in contact with on your own outdoor porch or patio.


The fabric samples are evaluated at 300-hour intervals for up to a total of 1,200 hours of exposure. These samples are then evaluated using the AATCC Grey Scale standard. A lab technician assigns the exposed fabric a value between 1 and 5, with the value of 5 representing no minimum change, and the value of 4 representing no visible change.


Phifer holds our fabric to an extremely high standard. That’s why we hold that a value of 4 is our absolute minimum for a passing grade on all of our fade-resistant fabrics. We believe that if a fabric isn’t tough enough to withstand the elements in our testing grounds, we won’t allow it to withstand the elements outside your home. Quality is our mission -- and so is making sure that our customers can purchase beautiful, sturdy fabrics with confidence. Phifer fabrics are designed to give you years of enjoyment -- whether you’re lounging by the pool or enjoying a cool summer breeze on the lanai.

Finding a Sun-Resistant Fabric That Fits Your Lifestyle -- No Matter Where You Live!

When you’re shopping for fade-resistant upholstery fabric to use outdoors, there are a lot of factors to consider. One of the most important factors is geography. The amount of UV exposure impacts how long it will last. For example, outdoor fabric living in cloudy Seattle is likely to see less direct sunlight than outdoor fabric used in “The Sunshine State” or in the deserts of Arizona.


If you live in a very sunny part of the world, it’s even more important to look for sun-resistant fabric and ask questions about how it will perform in your environment. You can extend the life of your fabric by keeping your outdoor furniture in partially-shaded areas: chances are you’ll appreciate the shade even more than the fabric when it really heats up outside!


The level of UV resistance of a fabric depends more upon the way it is manufactured than the type of material it’s made from. Natural fabrics such as silk, cotton and linen are most vulnerable to direct sun damage, while many of the best-performing outdoor fabrics are man-made. Phifer Designed Fabrics are built with performance in mind, bolstered by a solution-dyed processing and treated for UV resistance.
