Every garden needs improvement to make it attractive and provide a perfect relaxing environment. There are lots of materials garden owners can put in their garden, but few have lasting value. One material homeowners can use to improve their garden is composite decking. Plastic wood decking has been praised as the best outdoor flooring material available. The qualities range from attractive surface texture to easy maintenance and a long lifespan. But what about the outdoors? Few decking materials can survive the harsh weather condition of your garden. They will rot, swell, warp or splinter when you install them outdoors. So, is composite decking good for the outdoors? 

Tip: Composite decking is an outdoor flooring material that garden owners can use to make their backyard beautiful. Like wood and plastic, composite provides a perfect surface for your outdoor activities. But unlike wood and plastic, composite performs better under bad weather conditions. This makes composite one of the best outdoor flooring materials any homeowner can use in their yard. As a synthetic material, composite is similar to plastic but outperform plastic because it can be customized to look like timber decking, which most homeowners love. 

Why Is Composite Decking the Best Outdoor Flooring Material? 

To understand why composite decking is the best outdoor flooring material, we have to look at how it is made. Composite consist of two-component which are a core of durable lumber and polyethene plastic. The lumber supports composite decking, while the polymer encapsulates the decking and provides a protective shell. 

Co-extruded Cap

Composite decking has a capped surface around the boards and provides protection when you expose it to the elements. The co-extruded cap surface provides a shield from moisture, snow, heat and cold, making composite decking perform well when you install it outdoors. 

Composite Core

The core of composite decking is made of high quality and durable hardwood material. The hardwood is selected from recycled timber combined with a polymer to form a strong core for the new composite decking. This makes plastic wood decking 100% recyclable. 

So, you can see that composite decking material composition and how it is made, makes it the perfect material for outdoor flooring. The durable materials used to install composite decking prevent it from: 


Splitting is common in wood decking when you install it outdoors. When you build your deck with composite in your outdoor space, you can be assured that the boards will not split or break. This feature of plastic wood decking is one reason it will last longer than another outdoor decking. Composite decking has an impermeable layer of plastic that encapsulate the boards and prevent splitting on the surface. Splitting is not the only problem with wood. Timber decking will also warp, shrink and break as a result of expansion and moisture absorption. The polymer encapsulation on a plastic wood decking surface will prevent moisture and make it easy to expand without shrinking.  


Another reason composite decking is good for the outdoors is that the surface is resistant to stains. When you construct your deck in your garden, you will use it for your outdoor activities. Wine, soup, grease and oil can spill on your wood-plastic composite decking and dirty the surface. Getting stains off the top of timber decking is difficult. It is because garden owners have to scrub the surface vigorously. The timber surface does not have the plastic encapsulation of composite so that that stain will penetrate the boards. Plastic wood decking will not absorb stain, making it easy for homeowners to use a cloth or brush to clean their deck when they build it outdoor.

Mould Growth

The plastic encapsulation on the composite decking surface prevents mould and mildew from growing on it. This implies that mould will not eat into plastic wood decking boards and destroy them. Lumber decking, on the other hand, will not prevent mould growth. This makes composite decking good for outdoor flooring. Keep in mind that mould will grow on your composite decking surface if water settles on it. But you can easily remove mould from the surface by spraying your deck with a hose or scrubbing. Algae, like mould, will not discolour your plastic wood decking. Garden owners can easily clean the decking surface when they build it outdoors. 


Is composite decking good for the outdoors? Yes, plastic wood decking is perfect for the outdoors. This is because of the way wood-plastic composite is made. The plastic covering or encapsulation protect the surface from weather elements and make it last longer.
