Wood-plastic composite and PVC decking are latest innovations in decking techniques, made primarily from plastic material. The chief difference between the 2 types is the wooden fiber core of composite wooden decking, as well as some performance and upkeep points. Evaluating composite and PVC decking is basically easy, however there is considerable variation in the standard of each, depending on the producer.
Composite and PVC Decking Materials
The bottom ingredient for both wood-plastic composite (WPC) and PVC decking is plastic. PVC decking is made from virgin PVC, or polyvinyl chloride — a byproduct of the oil refining process and natural gasoline. Wooden-plastic composite uses polyethylene plastic, which comes from recycled plastic merchandise. Additives to help the manufacturing process and enhance suitability for development are necessary for the standard of both forms of decking and infrequently are the most expensive components of manufacturing.
A significant part in composite decking materials is floor-up wooden, referred to as wood flour. Varied sources present raw materials for wood flour, together with flooring factories, furniture makers and cabinet outlets. Variations between wood species and harvesting practices make producing consistent quality in composite decking a problem. Wooden flour also tends to create mold issues for the decking. Many composite decking manufacturers now encase the product in capstock, a plastic substance that protects the inside core of wooden fibers.
Composite decking is typically imprinted with a faux wooden-grain finish and a variety of colors with pleasing depth. PVC decking retains its plastic look in a restricted palette of neutral colours. The planks are sometimes embossed with treads for texture, providing traction and enhancing the appearance. Composite decking fades over time to varying degrees relying on the manufacturer, however generally inside three years the shade is kind of totally different. PVC decking retains its color, often warrantied for the lifetime of the proprietor.
Neither composite nor PVC decking is strong structurally, and both tend to sag without substantial assist. The surface of composite decking is well gouged, and the boards warp and splinter. PVC would not warp or splinter, but it’s subject to break from rocks, hail or objects thrown from a lawn mower. Composite decking must be sealed repeatedly as soon as its coating fades, whereas PVC requires solely periodic washing. Both kinds of decking retain heat to the point of being uncomfortable in scorching, sunny weather.
