The manufactures of composite decking figured a way to solve the few flaws that were associated with composite decking namely fading as well as mold issues. The resolution is whats now called cap stocked decking. To resolve the problems manufactures have made a composite deck board that has a vinyl exterior shell. It comes in many colors and is a grooved deck board so it can be attached to the floor joists using hidden fasteners so you don’t see the unsightly screw heads.The cap stock decking I use most is from a company called Trex and is there Transcend line of decking and railing. The decking is fade resistant, scratch resistant, and mold resistant and comes with a 25 year guarantee.
