The wall thickness of a vinyl fence can vary depending on the manufacturer and specific product. In general, vinyl fences have a wall thickness of between 0.125 inches and 0.5 inches. It is important to consider the wall thickness of a vinyl fence when purchasing one, as a thicker wall can provide more durability and strength to the fence. It is also important to consider the intended use of the fence and the local climate, as certain thicknesses may be more suitable for certain conditions. It is generally recommended to choose a vinyl fence with a thicker wall if it will be subjected to heavy use or if it will be installed in an area with extreme weather conditions. A durable fence, one that will withstand the test of time, needs to be at least .140 thick or higher.
