Composite
Commonly formed from recycled plastics and wood pieces, composite fences look like wood, but you’ll never have to paint or stain them. One of the main benefits of composite is the green factor — you are not using new lumber to build a fence. The wood in composite fencing material typically comes from recycled chips or sawdust. Composite fencing is dense, which makes it strong enough to stand up to the elements for years but it is still relatively lightweight.
Vinyl
Constructed strictly from PVC — polyvinyl chloride — vinyl fencing has the advantage of being inexpensive to buy and to maintain. If you are looking for a more modern fence, vinyl fencing is the answer. Like any plastic, it can be formed into any shape imaginable. Many vinyl fences are easier to install than composite because the panels notch together, rather than needing screws.
