Plastic decking has been around for a while and is an excellent option for homeowners looking to save on maintenance costs. It’s made from a mix of recycled and new materials, most notably polyvinyl chloride (PVC), and it can be molded into different shapes to create the look and feel of wood or other types of natural deck lumber. It’s waterproof and resists rot, mold, and mildew without the need for sealants or stains. It also has good short-term fade resistance and can be manufactured in a wide range of colors. Some manufacturers, such as Zuri, use cellular PVC and photorealistic print to make their boards look more realistic, but the material tends to be a little more expensive than other options.
Compared to traditional wood decking, a plastic deck requires less maintenance and can last up to 15 times longer. It is also more resistant to insects, fungus, and mold growth, and it can be molded into different shapes for a custom design. Most manufacturers offer a limited lifetime warranty for their plastic decking, although the duration of that warranty varies by product line.
The most popular plastic decking is made from either PVC or composite. Both types of materials are manufactured from recycled products, so they can help you reduce your environmental footprint. PVC plastic has a solid core and can be manufactured in various styles to resemble natural wood, while composite features a synthetic core that is encased in an organic or recycled cap for better weather resistance.
Aside from a few differences in appearance, both types of plastic decking are similar. They’re both low-maintenance and can add value to your home. Composite and capped PVC also have a higher strength to weight ratio than wood, making them more durable for heavy foot traffic and other uses.
While both plastic and composite can be crafted with a variety of color and grain patterns, most brands of composite and capped PVC have a more modern appearance than wood. Some manufacturers, such as Trex, have even been able to mimic the appearance of exotic woods for a more luxurious finish.
Both composite and capped PVC have a lower carbon footprint than natural wood, reducing the number of trees that need to be cut down to produce them. Plastic is recyclable, and it also has a lower risk of contaminating waterways and landfills, unlike wood.
Whether you choose a plastic or capped composite deck, it’s important to install them according to the manufacturer’s specifications to ensure a long lifespan and optimal performance. Both types are a bit heavier than natural wood, so you’ll need to plan for more structural support and make sure the joists can handle their extra weight. In addition, it’s crucial to leave enough room between boards for proper airflow and water drainage. Otherwise, moisture and debris may cause the boards to swell or warp, affecting their function and look. Fortunately, these issues are relatively easy to address.
