Duxxback Brand Decking from Green Bay Decking


DuxxBak™ is engineered to shed water from the deck while keeping the under-space dry, without the need for a secondary water-drainage system. Duxxbak™ diverts the water away from your home through its watertight design. The water travels through the Duxxbak™ channels and exits at the end of the deck. Create additional living space with Duxxbak™ decking.

DuxxBak™ offers more than just beauty. DuxxBak™ is the only complete non-vinyl, composite, water shedding deck system on the market.

DuxxBak™ not only creates a beautifully finished deck – but when installed on a 2nd level deck, the area underneath is instantly transformed into a dry outdoor patio or storage space. This allows homeowners the added advantage of having more usable outdoor deck space no matter the weather.

DuxxBak’s patented formulation is what makes it a step above the competition. With a combination of Biodac®, rice hulls, high density polyethylene resins, and other high quality ingredients, DuxxBak™ has high fade resistance and very minimal water absorption compared to wood-composite and PVC decking products.


With our patented, wood-free composite decking, you’ll never have to replace rotted, cracked, or warped boards again. You won’t be doing any more painting, staining, or waterproofing, either. Unlike traditional pressure treated decks, and in a niche of its own among composites, you can count on a lifetime of enjoyment on your new DuxxBak deck.

DuxxBak™ decking protects your home’s foundation by diverting water away from the building. And it safeguards your deck substructure from damaging water contact and moisture buildup common with many secondary, underdeck drainage systems.


DuxxBak is available in 5 Optima Finish, 4 Brushed Finish, and 2 Terrain Finish colors that will complement any house.

Important DuxxBak Installation Tips

Carefully review and follow the installation instructions and videos provided below. It’s a good idea to print the instructions and keep them handy during installation.

Hybrid-engineered composite decking will expand and contract as temperatures change. To minimize potential failure resulting from these movements, avoid installing your decking in extreme temperatures. The ideal installation temperature is 60 degrees Fahrenheit.

A gap of at least 3/16” must be provided where deck boards meet a house or other obstruction. That 3/16” gap must also be provided on each side of posts and other obstructions.

Use genuine Green Bay Decking fasteners, or equivalent.

All fasteners must be located a minimum of 3/4” from the ends of the deck boards. Additionally, any necessary face fasteners should be placed near the deck board structural septum, but not directly through the septum. Avoid over penetration of the fastener heads.

As with any manufactured decking product, be aware of conditions where reflective heat buildup from “Low-E” glass may cause damage to your deck.
