The Differences Between PVC and Composite Decking

PVC and ultradecking composite board are good building materials. If you want to build a deck in your home, you can use any of these materials depending on your choice. Although they are both deck building materials, they differ from each other. What are the differences between PVC and composite decking?

What is PVC?

PVC, also known as plastic decking, is a  synthetic decking material that contains 100% plastic material. It consists of polyvinyl chloride, a kind of vinyl you can use for outdoor fencing or siding. Polyvinyl chloride is a high strength plastic. Plastic decking has a good aesthetic, it is beautiful in appearance. It also does not require sanding, sealing or staining to keep it beautiful. Compared to composite decking, it also requires a low maintenance cost.

Additionally, plastic decking makers created PVC in varieties of colours and textures. Plastic deckings are resistant to scratch. If you use PVC in your home, your deck will not scratch over time. Also, plastic decking is resistant to stains, making it easy to maintain. Additionally, they are eco-friendly and do not pose a threat to the environment.

What is Composite Decking?

Composite decking is also known as WPC or wood-plastic composite decking. It is a mixture of recycled plastic materials and wood fibres. WPC builders combine these plastic and wood fibres in a co-extrusion process. The combined mixture is heated and moulded to form composite decking.

Composite decking is the best building material so far because of its outstanding qualities. It is a strong and resilient building material that has high strength compared to other deck materials.

WPCs are resistant to any weather conditions, they can thrive in hot and cold climates. It is also resistant to wear and tear due to prolonged use. Compared to plastic decking, it also can not scratch or dent. Furthermore, Composite decking can not rot, crack, warp or splinter. It is the best material you can use in making a deck. Additionally, it does not leach chemicals into the soil.

Differences Between PVC and Composite Decking

PVC and composite decking have some similar qualities, but they differ. Here are some differences between Plastic and composite decking.


You can differentiate plastic decking from composite decking by its appearance. Composite decking has the look of natural wood. It has a wood-like grain pattern compared to PVC.  Plastic decking does not look like wood. Pvc has a more synthetic wood-like appearance. It also has a more linear grain pattern. Additionally, unlike composite decking, PVC has a more aggressive texture.


Secondly, PVC and composite decking differ in composition. Plastic decking makers made PVC from 100% recycled plastic material. Unlike PVC, composite deck manufacturers produced composite decking from a mixture of wood fibres and recycled plastic material.


Additionally, their texture in cold seasons varies from each other. In cold seasons plastics decking are more slippery. Composite decking is not slippery like PVC, even in winter. You can walk on composite decking without falling in cold seasons, unlike plastic decking.

Resistant to Cracks

Another difference between PVC and composite decking is their ability to resist cracking.  Composite decking can not crack or splinter.  WPC makers formulated composite decking with materials that made it very strong. It is so powerful that it can overcome any weather conditions without getting damaged.

But unlike composite decking, plastic decking can crack. Plastic decking material made it from 100% plastic material. Pvc can not withstand diverse climate conditions like wood-plastic decking. Composite decking can expand with heat and contract in the cold without splintering. But plastic decking will splinter if it expands and contracts.


Finally, the difference between the two decking materials is that PVC is susceptible to fading and peeling.  Plastic decking can fade and scrape compared to composite decking. When it is exposed to the weather, plastic decking can peel and fade over time. In contrast, composite decking can not peel or fade if you expose it to the elements. Wood-plastic decking is infused with ultraviolet ray resistance that will prevent the decking from fading.


The differences between PVC and composite decking is easy to tell. They differ in appearance, texture, composition and ability to resist cracks and fading.
