DuxxBak Water-Shedding Decking - Armorcap Colors

Duxxbak is an interlocking gutter-style board profile where you can achieve a premium look, hidden-fastener appearance, and waterproof deck surface with just your decking, with no additional underdecking required.

Duxxbak can be installed with joists 24" on center (when installed perpendicular to joists), or for a 20+ foot wide deck, boards can be angled at 45 degrees with joists spaced 16" on center.
