Key Features of DuxxBak Decking
DuxxBak offers a number of technical and functional advantages that make it a preferred solution for modern outdoor construction projects. These features are outlined in the source material and are relevant to both residential and commercial applications.
Water-Shedding Design
The core function of DuxxBak is its ability to shed water without the need for an underdeck drainage system. The interlocking design of the deck boards channels water toward the edge of the deck, where it exits without pooling or seeping through the surface. This ensures that the space beneath the deck remains dry, making it suitable for extended outdoor living or storage.
Wood-Free Composite Material
Unlike traditional composite decking, which often includes wood flour, DuxxBak is entirely wood-free. The material is made from a combination of Biodac, rice hulls, polyethylene resins, and other high-quality ingredients. This composition results in a product that is more resistant to mold, mildew, and decay compared to wood-composite alternatives.
Structural Integrity and Durability
The decking is engineered to support 24-inch on-center joist spacing, reducing the need for additional framing. It is also rated for high mechanical strength and durability, making it suitable for both residential and commercial use. The system does not warp, crack, or crumble due to weather exposure, and it retains its structural integrity over time.
Low Maintenance and Longevity
DuxxBak requires no painting, staining, or additional waterproofing treatments. Its surface is designed to resist staining and fading, with a limited lifetime warranty covering defects in materials and workmanship. This makes it a cost-effective solution for long-term outdoor projects.
Aesthetic Options
The product is available in a variety of finishes and colors to suit different design preferences. The two primary finishes are:
- Traction Finish: A brushed surface that provides extra slip resistance, ideal for high-traffic or wet areas.
- Optima® Embossed Wood Grain Finish: A realistic wood grain pattern with a dual-embossed, variegated texture.
Color options include Walnut, Mahogany, Driftwood, Cedar, Copper Canyon, Rustic Red, Cool Sand, Boardwalk Grey, Warm Cedar, Black Walnut, Sedona Red, and Dark Mahogany.
Customization and Flexibility
DuxxBak offers multiple board profiles to accommodate different project requirements. These include:
- Fascia boards for finishing edges and transitions
- Solid board (Optima Profile) for seamless surfaces

- Strength-engineered commercial profile for high-load applications
The system can be manufactured in standard lengths of 12’, 16’, and 20’, with the option to produce custom lengths up to 24’ for specific project needs.
Installation Process Overview
The installation of DuxxBak is designed to be efficient and user-friendly, with a focus on minimizing labor costs and ensuring long-term performance. Based on the information provided, the following steps outline the general installation process:
1. Framing and Structural Preparation
Before installing DuxxBak decking, it is essential to ensure that the framing is properly prepared. The system is designed to be installed on joists spaced at 24 inches on center, which is a wider spacing than many traditional decking systems. This reduces the amount of framing material required and simplifies the installation process.
The framing should be sloped at a minimum of 1/8 inch per foot to facilitate water drainage toward the edge of the deck. This slope is critical to the functionality of the water-shedding system, as it ensures that water flows along the surface and exits the deck without pooling or seeping through the boards.
2. Deck Board Installation
DuxxBak decking boards are installed using hidden fasteners, which eliminates the need for visible screws or face-mounted hardware. The interlocking design of the boards allows for a seamless fit, reducing the risk of gaps or misalignment.
The boards are installed in a direction that aligns with the natural slope of the deck, ensuring that water is directed toward the edge. The interlocking channels in the board surface help to channel water along the length of the deck and out over the edge.
3. Edge and Transition Details
DuxxBak offers a range of complementary railing options and transition pieces to ensure a finished look and seamless integration with surrounding structures. Fascia boards are used to cap the ends of the deck and provide a clean, finished appearance. These boards also serve to reinforce the edges and prevent water from seeping into the framing.
Transitions between different materials or levels can be handled using specially designed transition strips or by adjusting the slope and alignment of the deck.
4. Finishing Touches
Once the decking is installed, the final step is to ensure that all transitions, edges, and connections are properly sealed and secured. While DuxxBak does not require additional waterproofing or sealing treatments, it is important to ensure that all connections are tight and that the deck is properly aligned to facilitate water flow.
5. Post-Installation Considerations
After installation, the deck should be regularly inspected for signs of wear or damage. While the material is highly durable and resistant to weathering, it is still important to maintain the structure to ensure long-term performance. This includes checking for loose fasteners, ensuring proper drainage, and cleaning the surface as needed.
