What is PVC Decking?

When looking for an alternative to traditional wood decking, you have many options; among them, capped composites and PVC decking.
What is PVC Decking?

Faithful readers of the Fiberon blog are familiar with the many benefits of capped composites; however, you may not know quite as much about PVC decking. Here’s a quick overview of what PVC decking is, its benefits, and when it might be the best choice for your particular deck or porch project.

PVC Decking offers rich wood aesthetics with super-easy maintenance.

PVC Decking: able to withstand moisture, dents, heavy foot traffic, and even flames

PVC stands for polyvinylchloride, which is the world’s third most widely produced synthetic plastic polymer. Chances are you already have some PVC products in or on your home: PVC-clad windows, trim, or lattice work, to name a few. Because of its chemical composition, PVC is a durable material that is highly resistant to moisture, insects, dents, and even flames, making it a smart choice for many decking and porch applications.

  • PVC decking contains no organic content. That means there’s nothing to promote mold growth, a big concern in damp areas such as lakes, marinas, or beachfront properties. Moisture resistance is the main reason why many homeowners and contractors choose PVC decking for waterside applications.
  • PVC decking resists insect infestation. Lack of organic content also means there is nothing for hungry bugs to feast upon, so no need to worry about creepy crawlies destroying your beautiful outdoor space.
  • PVC decking resists dents. It’s well-suited for high-traffic areas. Plus, whether wet or dry, it is highly slip-resistant. Another bonus for the contractor or DIYer: The boards are lightweight, so they are easier to carry and work with than other options.
  • PVC decking is flame resistant. It may not be the first thing most people think about when selecting decking material, but flame-resistance is a very important consideration if you reside where fires are a chief concern, such as Wildland Urban Interface (WUI) zones. In these locations, check that any decking you are considering is WUI-approved and complies with all relevant building codes regarding flame spread indices and wildfire exposure.
  • PVC decking is easy to maintain. Just as with capped composites, PVC decking never needs repainting, re-staining, or refinishing. An annual cleaning with mild detergent and water is usually all that’s needed to keep the boards looking their best. Of course, always consult the decking’s care and maintenance guide before using any cleaners or chemicals on the decking.

For the best project outcome, follow installation instructions carefully

Of course, there are some drawbacks with PVC decking – none too overwhelming, but it pays to be informed.

  • Temperature fluctuations: PVC decking will expand and contract with temperature changes. Your decking installation instructions will likely include recommendations for spacing (gapping) between the boards. Follow these guidelines carefully, as they will ensure there is adequate air flow and drainage at all times. Another way to minimize the impact of expansions/contractions involves the decking color and the length of the board runs. Lighter colors naturally absorb less heat, so they will not expand as much. Consider lighter colors for the body of your deck with darker shades around the edge or used as an inlay. Use shorter boards wherever possible, and incorporate a splitter or divider board (also called a breaker board) between each continuous run of longer boards.
  • Construction best practices: Neither PVC nor composite decking products are made to support a deck structurally. The boards must be installed over traditional wood posts and joists.
  • Cost: Generally speaking, PVC decking is more expensive than wood decking. However, before making your final decision, calculate the added expense of regular care and maintenance as well as periodic refinishing of a wood deck. Depending on where you live and how large your outdoor space is, you could be looking at a fairly significant outlay of cash. Long-term maintenance savings with PVC decking may balance out the higher initial expense.
  • Chemical interactions: Some brands of insect repellent and suntan lotions can stain PVC decking. In fact, these products can create problems on virtually any kind of decking. It’s best to avoid applying bug sprays or sunblock while standing on your deck. Also, do not use rubber, vinyl or polypropylene-backed rugs or mats on PVC decking. Stick with colorfast cotton rugs to avoid any possible reactions that could result in decking discoloration.
