Does vinyl fencing really stand up to the wind?

In most cases. Yes. Quality vinyl fencing material is designed to stand up to just about anything mother nature can throw at it, short of being in the path of a “major” hurricane or tornado. Improvements in vinyl extrusion technology and the engineering processes of vinyl fencing systems over the years have come an incredibly long way since the initial days of vinyl fencing. Most vinyl fences are designed to withstand normal wind load. The amount of load is dependent on the installation of the posts and horizontal rails.
