Vinyl fencing will serve as a fine substitute for wood in most circumstances. It also has some advantages over wood, in that it will not splinter or rot, and does not need pre-treatment or stain application. Vinyl fences are durable and long-lasting, not to mention very weather-resistant.
Fences that can be built using vinyl include privacy fences, picket fences, and many more. These can also be crafted to various heights and widths, depending on your needs.
