Some have wondered if composite decking can rot like wood. Composite decking will not rot like wood decking. Even in the presence of moisture, the decking will still not decay. It makes composite boards superior to wood decking. Homeowners aware of this benefit of composite decking over wood have replaced their wood decking with composite boards. But why does composite decking not rot like wood if you expose it to moisture? It is good to know the reasons. This article will tell you more about composite decking.
What is Composite Decking
Composite decking board is a strong and durable decking material that contains both wood fibres and recycled plastic. Because of its component, composite decking is commonly referred to as wood-plastic decking or plastic wood decking. Wood-plastic decking is very beautiful and comes in varieties of colours. The composite decking is different from wood decking since wood is natural and made from 100% timber.
Types Of Composite Decking
There are different types of composite decking. But in this article, we will discuss the capped composite decking and the uncapped composite decking.
Capped Composite Decking
The capped composite decking has a high resistance to water or moisture. It has an additional covering on its outer layer. The plastic coating around the capped decking prevents the decking board from absorbing moisture from the environment.
Since it has a plastic coating around it, the capped composite decking is the best option for places with high moisture or wet areas. The decking board will not absorb water, so it will not rot. For a material, to rods, the material must have absorbed water or moisture. When the material absorbs moisture, it will decay over time. So if you want to build your composite decking yourself around a swimming area or close to a dock, capped composite decking is the best option.
Uncapped Composite Decking
The uncapped composite decking is the opposite of the capped composite decking. It does not have an additional plastic covering on its outer part. Since it does not have a plastic coating around the board, it does not mean that it will not last long. The uncapped decking will not absorb moisture or water easily like wood. Remember that composite decking is made from both plastic and wood fibre. The plastic material in the decking made it not easily absorb moisture like wood.
But, If you compare the two decking types, the capped decking is more resistant to moisture than uncapped decking. The uncapped decking is suitable in dry places or covered places. It is not suitable for installing in wet areas. Homeowners who want to build composite decking under a shed can use uncapped decking. The shed will prevent rainwater from dropping on the decking so that it won’t absorb water. Like the capped decking, the uncapped decking will not damage easily and will also last long.
What Cause Decking to Rot
Wood decking is not resistant to moisture; that is why wood rots easily. When humidity is high, wood absorbs moisture from the atmosphere and swells. The high moisture content of the wood would eventually make it decay over time.
Timber decking is also not resistant to insects like termites. Termites can penetrate the wood and eat it, thereby making the wood rot. This insect bore through the structure, thereby damaging it.
Why Composite Decking Will Not Rot
Knowing what composite decking is and the type of composite decking, let us consider why composite decking will not rot. Remember that composite decking is made up of wood fibres and plastics. These two materials are mixed in the factory to form a composite decking board. It makes composite decking highly durable than wood. And also, since the material contains plastic, it is difficult for the composite board to absorb moisture like wood. The composite decking has an extra coating on its outer layer that prevents moisture absorption.
Wood decking, on the other hand, does not have any protection on its outer part. The wood will readily absorb moisture from the environment if there’s a weather change. And when this happens, the wood will swell and rot over time. But composite decking will not absorb moisture, so there is zero possibility that composite decking boards will rot.
Will composite decking rot? The decking will not swell and rot when exposed to moisture. It makes complete decking superior to wood decking.
