They also come in reversible grain enabling you to create a pattern to your design by simply turning the boards over. For instance, the style of decking I used had a smooth grain on one side and a "wood" grain on the other. By simply turning certain boards over, I was able to create a look that was diversified. This may not be something you would want to do, but it is nice to have the option.Finally and I know this is not everyone's main concern, but it is a plus. A percentage of composite decking is made from recycled material. When I look out on my deck and I see this beautiful surface, that I know I do not have to sand and seal, that I will no longer hear the theme from Jaws, that there will be no insects feasting on my gathering place, and that its make up consists of recycled materials.... I love it all the more. In your research you will find drawbacks to composite decking, let's face it, there is no perfect solution. The initial cost will be more compared to some wood products. The construction specifications are more demanding than wood products, in regard to the span of your joists, further adding to the cost.
