A mineral-based composite deck board designed with flat-grain variegation that is lightweight, strong and stable.

*Currently unavailable in Canada

Our Vault family is made with patented mineral-based composite technology, which provides the industry’s best strength-to-weight ratio and has virtually no thermal expansion or contraction. It’s powerful, stable and doesn’t absorb moisture. The mineral-based composite technology inside Deckorators® Vault™ allows the decking to be lightweight, but creates a fiber-like structure inside, similar to wood, giving it unmatched strength. The lightweight boards are easy-to-handle on the job site and have similar properties to PVC; however, unlike PVC and other composites, Vault won’t splinter, sag, chalk or crack.

Grooved-edge decking gives a clean, fastener-free appearance to the surface of your Deckorators deck. StowawayTM hidden fasteners are a perfect way to discreetly secure deck boards to joists using the grooved edges.

The solid-edge profile is ideal when board edges are visible, such as picture-frame boards or stair treads. Solid deck boards should be fastened through the top of the board using composite deck screws.
