Composite decking is decking material made from an engineered wood product. It contains a mix of resins and wood or cellulose material. It can be purchased at many home improvement stores and construction suppliers in addition to being ordered directly through manufacturers.
As with wood itself, composite decking comes in an array of colors and degrees of quality. It is advisable to look up reviews before purchasing composite products.
Composite or engineered wood is made with shredded wood and cellulose material, often waste products from wood manufacturing, mixed with plastic resins. These materials are specially treated and injected into molds. Typically the molds have a wood grain pattern and the mixture may be dyed to give it a wood-like appearance.
Composite decking is designed to be used without paint or varnish, an important trait to keep in mind when making decisions about the color of the product being installed.
The mix of wood and resin can vary, depending on the product. The more wood, the more chances that composite decking will attract fungus and eventually rot, mold, and mildew. Problems with composite decking can include staining, scratching, and cracking. There are sealants available to keep composite materials in good condition and it is also a good idea to periodically scrub down the decking with a product approved for use by the manufacturer
