Capped Composites
The next generation of composite decking includes a durable plastic cap that adds added protection. A PVC cap surrounding the wood plastic composite material helps reduce staining, fading and scratching that may occur with 1st generation composite decking.

They will also have the same properties of reducing staining, fading, and scratching.
