Common Problems With Composite Deckings

Composite decking is also known as wood-plastic decking or WPC. It consists of wood fibers and recycled plastic material. The materials are combined with a bonding agent, heated, and allowed to cool to form composite decking. Composite decking is a more durable decking material than wood or plastic decking. Apart from that, composite decking is resistant to the elements and can not crack or splinter.

The plastic material in the composite decking makes it so hot that you can’t walk on it with your barefoot when it’s sunny. The only way to prevent that from happening is if you build a shed over the composite deck. Another factor that can contribute to its hotness is the color of the decking. If your composite decking is dark in color, it will get hot easily when exposed to the sun. A reason for this is that dark colors absorb heat compared to lighter ones. 

Composite Decking is Difficult to Replace
