Which is better?
PVC deck boards are a budget-friendly choice that require minimal maintenance. But when we compare composite vs PVC decking, which is the better choice for your decking project and why?
What’s the difference between PVC decking and composite decking?
Many people use the terms PVC/uPVC decking and composite decking interchangeably, but it’s important to be clear on the terminology and difference between plastic and composite decking before you make your purchase.
PVC decking PVC (polyvinyl chloride) decking is a form of plastic/vinyl that contains plasticizer additives that make it a softer and more flexible material.
uPVC decking uPVC (un-plasticised polyvinyl chloride) is another form of plastic/vinyl without any additives. This makes it a more rigid and durable material.
Composite decking In comparison to PVC and UPVC decking, composite decking, also known as wood plastic composite (WPC), is made by blending synthetic materials with natural wood fibre.
So, should I buy composite or vinyl decking?
Both uPVC/PVC plastic decking and composite decking require minimal maintenance. They both offer stain and mould resistance which is perfect for bouts of cold or damp weather.
The main disadvantage of uPVC and PVC vinyl decking is that it is water resistant but slippery in wet conditions. This means that you may spend more money on rubber mats, oils, or non-slip strips to fix the issue if you choose vinyl decking.
Alternatively, composite decking provides excellent grip due to its natural wood-like texture. It also has excellent moisture resistance with the added beauty and slip-resistance of natural wood.
You will usually find that uPVC decking boards are far more expensive than WPC decking. We’d recommend composite decking if you’re on a tight budget, as it is a great long-term investment for a high quality, sustainable and eco-friendly deck.
Vinyl decking can cost £20 to £125 per metre, whereas our cheapest composite decking starts at £25.74, and this includes all of the incredible aesthetic and maintenance benefits of having high-quality WPC decking.
It’s also important to note that price reflects quality when buying vinyl decking, so you’ll probably be spending a lot more than expected if you choose uPVC decking.
Put simply, composite decking boards have a much longer lifespan than PVC deck boards. Composite decking has a brilliant extended warranty and lasts around 25-30 years!
Vinyl decking has a much shorter lifespan than composite decking due to the fact that it is made of 100% synthetic plastic. When plastics are exposed to extreme temperatures, the material will weaken.
On the other hand, composite decking is designed to flex, expand, and contract with extreme weather changes. This is due to the combination of wood fibres and plastic polymers, creating a fusion of materials than can handle heat expansion and contraction.
