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 16" O.C. when installed at a 45 degree angle. Installing at an angle is a great way to get continuous boards on 21+ foot wide decks, since the boards will direct water towards the front of the deck.
