Vinyl fencing is known for its durability and ability to withstand various weather conditions, including high temperatures and UV light. To prove this point, today is day 18 in a row with temperatures over 110° Fahrenheit in Phoenix, AZ. This is tying a record for Phoenix, AZ that was set in 1974. Here's how vinyl fencing holds up under these extreme conditions:
1. High Temperatures: Vinyl fencing is designed to be heat-resistant. It can withstand high temperatures without warping, melting, or becoming structurally compromised. Vinyl fences are typically made with a combination of PVC (polyvinyl chloride) and other additives that enhance their heat resistance. These additives help the vinyl fence maintain its shape and structural integrity even in hot climates or during heatwaves.
I took two pictures to show a real-life example. My fence was installed about 2 years ago. Today’s (7/16/2023) high is 117 °F. The pictures show an 8-foot section of fence, I placed a 4’ level in the top rail and there are no gaps under the level. That means the vinyl did not warp or sag under the extreme heat. The other pictures show that the fence is about the same temperature as the air. No burning if you touch the fence and no retaining heat when the sun goes down.
2. UV Light Resistance: Vinyl fencing is also highly resistant to UV light. The PVC used in vinyl fences contains additives that protect it from the damaging effects of the sun's ultraviolet (UV) rays. These additives act as UV stabilizers (Ti) or inhibitors, which prevent the fence from fading, yellowing, or becoming brittle over time. The UV stabilizers reflect the UV rays, reducing their impact on the vinyl material and extending the lifespan of the fence. In our example, a white vinyl fence will be within a degree or two of the air temperature. The UV light on white vinyl did not
3. Color Retention: Vinyl fencing is available in various colors, and its color retention is another notable advantage. The UV stabilizers not only protect the vinyl from UV damage but also help maintain the original color of the fence. This means that even with prolonged exposure to sunlight, the color of a vinyl fence will remain vibrant and fade-resistant, requiring minimal maintenance.
4. Low Maintenance: Vinyl fencing is highly regarded for its low maintenance requirements. Unlike wood or metal fences, vinyl fences do not need to be painted, stained, or sealed to maintain their appearance and protection against the elements. Cleaning the fence periodically with mild soap and water is usually sufficient to keep it looking good.
It's important to note that while vinyl fencing is highly resistant to high temperatures and UV light, extreme conditions such as intense heat or prolonged exposure to direct sunlight can still affect any material over time. However, compared to other fencing materials, vinyl is considered a reliable and durable option for withstanding these conditions while requiring minimal maintenance.
